Section 1.1 - Key features

•

Up to ten different setups can be stored and

recalled, allowing instant re-configuration, not

only of the RC-898, but also of all DTRS units

connected to it.

1 – Introduction

The RC-898 is a fully-featured remote control

unit, which allows you to control up to six DTRS

units (DA-98, DA-88 or DA-38 units) with a sin-

gle cable, as well as units implementing the Sony

P2 protocol, or using parallel control. As an alter-

native to parallel control, up to five GPI event-

controlled units can be connected.

1.2 Unpacking

The box contains the following.

•

RC-898 Remote Control Unit (x 1)

Accessories:

•

Remote/sync connection cable (x 1)

Remote/sync terminator (x 1)

This manual (x 1)

In addition to providing almost all functions avail-

able from the front panels of the DTRS units, the

RC-898 in some cases actually extends the capa-

bilities of the basic DTRS system.

1.1 Key features

1.3 About this manual

•

DTRS units controlled by the RC-898 are

locked to sample accuracy, providing you with

a “virtual” digital multitrack recorder, with up

to 48 tracks.

This manual is written in sections according to the

function that you will be performing.

•

Section 1 - “Introduction”: This section.

•

Up to 99 location memories may be entered (or

captured) and edited to frame accuracy, for

marking important points in a recording

project.

Section 2 - “RC-898 features”: The front and

rear panel features of the RC-898.

•

Section 3 - “Connections”: How to hook up the

RC-898 with other equipment.

•

Timecode values are entered and edited using a

positive-feel numeric keypad.

Section 4 - “Menu and basic operations”: How

to use the menu system, and the basic princi-

ples of operating the RC-898.

The DTRS units’ transport functions, including

the shuttle control, are duplicated on the RC-

898. These transport controls may also be used

to control the RS-422 or parallel external

machine.

•

Section 5 - “Basic DTRS operations”: The

main everyday transport and other operations

that you will perform when using the RC-898

with DTRS units.

•

The RC-898 also features a jog dial, allowing

frame-by-frame manual location.

•

Section 6 - “Location functions”: Using the

location functions of the RC-898.

The jog dial can also be used as a data entry

control for the entry of location point and other

values.

Section 7 - “Making settings on the DTRS

units”: more advanced DTRS settings, that you

will probably not need to make every day.

•

Auto-punch operations are fully supported. The

RC-898 provides one-key operation for

rehearsal and recording with automated punch

points.

•

Section 8 - “Timecode functions”: Functions

related to timecode and DTRS units.

Section 9 - “External control and settings”:

Other control functions, and control of units

other than DTRS (P2, GPI, etc.).

System settings, for the DTRS units and for the

RC-898 itself, are made using a convenient

menu system, and displayed on a clear backlit

20-character x 4-line display.

•

Section 10 - “Menu and parameter reference”:

A guide to the menu items, together with

parameters and default values.

The most frequently-accessed setting menus

can be assigned to function keys, so that they

may be easily recalled.

Please check both the Table of Contents and the

Index when you are searching for a particular

function or operation. There is also a guide to the

different menu screens available on the RC-898

(10, “Menu and parameter reference”).

•

Lighted indicators give an instant indication of

the status of the most important functions.

All timecode formats are supported, as well as

pull-up/pull-down, making the RC-898 the

ideal choice for post-production work in both

the movie and video fields.

When describing a control, display or connector,

the name of the control is emphasized, as: “Press

the STR key [17]”, or “the CONFIDENCE indi-

cator [10] will light”. The number in brackets fol-

lowing the name of the control is the number of

the control as shown on the front panel illustra-

tion, as well as that used in the appropriate sec-

tions describing the front and rear panels.

•

Relative humidity should be between 30% and

80% non-condensing

•

Avoid spraying polish, insecticides, etc. near

the RC-898.

WARNING

A special font is used for showing the messages

that appear on the LCD display screen [11], for

example: ^9PinLocate Preroll.

If you need to clean the unit, use a soft cloth, moistened if

necessary with a little detergent and water. Do not use abra-

sive cleaners or solvents such as alcohol or thinner.

When describing a value as shown on the TAPE

TIME [13], MEMORY NO [14], or LOCATE

TIME/VALUE [15] displays, the following font is

used: 00:23:45:12 or on.

•

Avoid subjecting the RC-898 to jolts, sudden

shocks, etc.

WARNING

Some functions of the RC-898 apply to all DTRS

recorders, some only to DA-98 units, some to DA-

38 units and some to DA-88 units with the SY-88

synchronizer board fitted. Wherever appropriate,

this manual will use combinations of the follow-

ing symbols to show what operations may be per-

formed with the different units in the DTRS range:

If you have to return the unit for service or repair, use the

original packing materials if possible. If the unit is to be

transported to a recording location, etc., use a suitable trans-

port case with sufficient shock protection.

TASCAM does not accept responsibility for dam-

age resulting from neglect or accident.

1.4.2 Battery backup

The RC-898 requires no power supply of its own,

drawing its power from the DTRS units to which

it is connected.

All units

No symbol

DA-88 with SY-88

DA-38

Location memories and configuration settings are

stored using a battery backup system. The battery

should provide power for several years of use.

When the battery eventually degrades to the point

where it cannot provide enough power to retain

settings, the message ^MemoryErrorwill

be shown on the display screen (this can be

removed by pressing the ESCAPE key).

DA-98

This manual may also make references to the

manuals of the DTRS units and the SY-88. In the

case of the DA-98 and DA-38, these references

will be made in terms of section numbers (e.g.

“4.2” and “4-5” respectively). In the case of the

DA-88 and SY-88, page numbers will be provided

(e.g. “p16” and “p5-7” respectively).

When this message appears, all memories (loca-

tion memories and configuration settings) are

cleared and reset to the default settings.

1.4 Precautions and

recommendations

If you see this message, contact your TASCAM

dealer for details of battery replacement. Do not

attempt to replace the battery by yourself.

As with every precision piece of electronic equip-

ment, common-sense precautions apply with the

RC-898.

1.4.3 Digital audio cables

When making connections between TASCAM

digital audio units, always use genuine TASCAM

cables. This applies particularly to any T-DIF dig-

However, you should note the following points in

particular with regard to the operation of the unit:

1.4.1 Environmental conditions

The RC-898 can be operated in most environ-

ments, but we suggest that you keep the environ-

mental conditions within the following limits:

•

Ambient temperature between 5° and 35° C

(41° and 95° F).

1-2

Section 1.5 - Accessories

ital audio connections between DTRS recorders,

DTRS recorders and digital mixing consoles, etc.

WARNING

Only use TASCAM-supplied and TASCAM-approved

cables when making such connections. Though the cables

and connectors may resemble computer cables, they serve

different purposes, and meet a different set of specifications.

The use of cables other than TASCAM cables will at best

cause the equipment to work erratically, and at worst cause

damage to the equipment.

If the use of cables other than TASCAM cables causes or

results in damage, the warranty is voided.

1.4.4 Reference clock in a digital studio

It is likely that the RC-898 will be operated in an

environment where there is more than one digital

audio source available.

If this is the case, you must make sure that all dig-

ital audio sources in the setup are driven by the

same reference clock signal (“word clock” or

“Word sync”).

If different clock sources are used throughout a

setup, it is actually possible to damage speakers,

etc. because of mismatches.

1.5 Accessories

Despite the powerful range of functions which

may be controlled from the RC-898, the unit is

relatively compact. It may be found convenient to

mount the RC-898 on a roll-around stand, avail-

able as CS-898.

Should you need extension meters from the tape

decks, this can be achieved using MU-8824 meter

units and appropriate mounting hardware (MK-

8924).

Section 2.1 - Front panel

This section gives a brief overview of the front

and rear panel controls and their functions.

ual tracks when ALL INPUT is turned off again.

Start recording or re-set the REC FUNCTION

keys to restore this.

2.1 Front panel

[5]

AUTO MON key and indicator

[1]

REC FUNCTION keys

This key performs the same function as the AUTO

MON key on a DA-98. However, the DA-88 and

DA-38 are not equipped with a key with this label,

so the function is slightly different when control-

ling one of these units.

These keys with integral indicators allow you to

set and view the track arming status of up to six

DTRS units attached to the RC-898, or five DTRS

units and another recorder.

Tracks 1 through 8 apply to the first unit, 9

through 16 to the second, and so on.

Pressing this key is the equivalent of pressing the

INSERT key on a connected DA-38, and pressing

both the AUTO INPUT and INSERT keys on a

DA-88. It is used in punch modes to switch auto-

matically between tape and source when punching

in and out automatically. The indicator lights

when this function is active.

The last eight are used to control tracks 41

through 48 (the sixth DTRS unit) or may be used

for the two analog and four digital tracks of a P2

recorder, as marked (A1, A2, and D1 through

D4). These keys are only available for this pur-

pose when recording is enabled for the P2 unit

(see 9.3.5, “Controlling recording operations on

the serial unit”). When used to control the P2 unit

in this way, the last two REC FUNCTION keys

are unused.

Note that the status of the INPUT MONITOR

keys on a DA-98 will be overridden by the AUTO

MON key. However, when AUTO MON is turned

off again, the original status of these keys will be

restored.

[2]

INPUT MONITOR keys

Changing the REC FUNCTION status of DA-98

tracks while AUTO MON is on will lose the rela-

tionship between the REC FUNCTION and

INPUT MONITOR status for individual tracks

when AUTO MON is turned off again. Start

recording or re-set the REC FUNCTION keys to

restore this.

These keys with integral indicators allow you to

set and view the input monitoring status of the

tracks of any DA-98 units attached to the RC-898.

See section 7.1 of the DA-98 manual for details of

the operation of these keys, which function in the

same way as the keys on the RC-898.

When the RC-898 is used to control DA-88 and

DA-38 units, the keys cannot be used, but the indi-

cators still reflect the current monitoring status, on

a track-by-track basis, of the connected units.

[6]

[7]

CLOCK indicators (INT, WORD and

VIDEO)

These indicators correspond to the indicators with

the same names on the currently-selected DTRS

unit.

[3]

[4]

ALL SAFE key

This key (with integral indicator) is equivalent to

turning off all the REC FUNCTION keys [1].

When all tracks are safed in this way, the ALL

SAFE indicator lights. When the ALL SAFE

mode is turned off (the indicator goes out), the

previous track arming status will be restored.

To use the RC-898 to change the clock source on a

DTRS unit , see 7.2.6, “Clock selection”.

TC indicators (24, 25, 29, 30, DF)

These indicators correspond to the system time-

code type of the currently-selected DTRS unit.

ALL INPUT key and indicator

This key (with integral indicator) performs the

function of the ALL INPUT key on the connected

DTRS units. The indicator lights when the func-

tion is active.

Here, the 29 on the RC-898 panel is an abbrevia-

tion for “29.97”. The

indicator will light if the

timecode is in drop-frame format.The supported

timecode types are therefore:

24fps (cine)

The INPUT MONITOR keys on a DA-98 also

affect the switching between source and tape.

Changing the REC FUNCTION status of any

tracks while the ALL INPUT function is on will

lose the relationship between the REC FUNC-

TION and INPUT MONITOR status for individ-

25fps (PAL/SECAM)

29.97 (NTSC color non-drop)

These controls work with DTRS units and with

units connected to the EXT 2 control port [43].

[22] F1 through F10 function keys

These keys are used with frequently-used menus,

so that one keypress will bring up these menus.

The keys may be “shifted” [23] to provide a sec-

ond bank of 10 less frequently-used menu keys.

They are used to simulate the “rock and roll” of an

open-reel tape deck, allowing precise positioning

of the controlled units. The indicators above the

controls show the current direction of the

medium’s movement.

[23] SHIFT key

This key is used to provide a second bank of ten

function keys for quick access to frequently-used

menus.

When the DATA INC/DEC indicator [27] is lit,

the JOG dial acts as a data editing control for the

least significant field of the value shown in the

LOCATE TIME/VALUE display [15].

It is also used with the UP and DOWN keys [25]

to use them as NEXT and PREVIOUS keys for

the selection of machines in the display screen

menus.

[29] CAPTURE key

When this is pressed, the current time is displayed

on the LOCATE TIME/VALUE display [15]

where it may be edited and stored as a location

memory, or used for “one-shot” location purposes.

It is also used in conjunction with the ENTER/

LOAD key [20] to transfer entered values to the

parameters being set in the display screen.

[33] AUTO PLAY key and indicator

This key with its integral indicator works with

DTRS units. It allows the units to start playing

back automatically when a location point is

reached.

These transport controls duplicate those available

on DTRS units. They may also be used to control

units connected to the E1 (parallel) and E2 (9-pin

serial) ports when the appropriate machine is

selected ([8] and [31]).

[34] PRRL key and indicator

This key with its integral indicator works with

DTRS units. It is used to locate the tape to the

punch-in position, minus the pre-roll time set for

punch operations (see 6.7.5, “Setting pre-roll and

post-roll times”).

[41] LOC key

This key provides one-touch operation to allow

location to the memory position shown on the

LOCATE TIME/VALUE display [15]. If a loca-

tion pre-roll time has been set (see 6.5.1, “Setting

the location pre-roll value”) the pre-roll offset will

be subtracted from the location value, and the

location will be to that new calculated value.

For instance, if the punch pre-roll value is set to 5

seconds, and the punch-in point is “00:55:12:12”,

the unit will finish locating at 00:55:07:12.

[35] RHSL key and indicator

This key allows you to rehearse auto-punch opera-

tions on the units connected to the RC-898. For

full details, see 6.7, “Punch operations”.

This port provides parallel control and tally sig-

nals or GPI control for event control, which may

be triggered from a small “cue list” in the RC-898.

[36] AUTO PUNCH key and indicator

This key allows you to perform auto-punch opera-

tions on the units connected to the RC-898. For

full details, see 6.7, “Punch operations”.

The pinout for this 15-pin ’D’-sub connector is

given in 3.2, “Connections (parallel units)”. You

will need to make your own cable, referring to the

the table above, and to the equivalent table in the

manual of the other equipment if you wish to con-

trol an external unit through parallel control, or if

you wish to send GPI events from the RC-898.

NOTE

The two keys above do not work in the same way as the

rehearsal and auto punch keys on DTRS units. Even if you

are an experienced user of DTRS equipment, we recom-

mend that you read 6.7, “Punch operations” to get a full

understanding of punch operations when using the RC-898

to control recording operations.

[43] EXT 2 - serial port

This 9-pin ‘D’-sub connector is used for the con-

trol of devices implementing the Sony P2 proto-

col. A cable designed for P2 connections may be

used with this port.

[44] REMOTE OUT connector

This connector is used for the control of the DTRS

units. It should be connected to the REMOTE IN/

SYNC IN of the first DTRS unit in the chain.

[38] MARK OUT key

This key allows you to set and check the punch-

out point for automatic punch operations. For full

details of how to use this key, see 6.7.1, “Setting

[45] DIP switches (1 & 2)

The two DIP switches are both on when in the

down position. As shipped from the factory,

switch 1 is off (up) and switch 2 is on (dow), and

you probably will not need to change them.

However, when a passive device is connected to

the EXT 1 connector and power is not provided

from the device to the tally supply pin, this switch

1 (TALLY POWER) should be set to the on

(down) position, allowing the RC-898 to use its

own power for this purpose.

Switch 2, GND LIFT (ground lift) controls the

isolation of the ground of the RC-848/DTRS sys-

tem from the ground of devices attached to the

EXT 1 and EXT 2 ports. Usually this switch is in

the on (down) position, but you may need to turn it

off (up) if your system suffers from hum prob-

lems. However, a full discussion of ground loops

and their associated problems is outside the scope

of this manual, and we recommend that you con-

sult one of the many reference works on this sub-

ject if necessary.

WARNING

All connections to the RC-898 should be made with the

power to all units turned off. If this is not done, the opera-

tion of the units may become unstable, and damage may

possibly occur.

Turn off power to all units when making connections. If you

do not do this, there is a possibility that the RC-898 will

malfunction or even be damaged.

3.1 Connection to DTRS units

The RC-898’s REC FUNCTION and INPUT

MONITOR keys 1 through 8 now control the first

unit, Keys 9 through 16 control the next unit in

the chain, and so on (regardless of the actual

Machine IDs of the units).

The RC-898 and DTRS units form a “daisy-

chain”, with the RC-898 being at the head, and the

“tail” unit being terminated with the terminator

supplied with the RC-898.

NOTE

Tighten the screws holding the cable connector to

the RC-898 and to the DTRS unit. This will pre-

vent accidental disconnection of the RC-898 in the

middle of a session.

When you connect a number of DTRS units which are of

different types, including DA-98s, the DA-98 units should

be at the head of the chain immediately following the RC-

898. Any DA-38 and DA-88 units should then be connected

following the DA-98s. If there is more than one DA-98 in

the chain, they should be connected together, before the DA-

38s and DA-88s. The order of the DA-38 and DA-88 units is

not important.

WARNING

Use only TASCAM cables to connect the RC-898 to the first

DTRS unit, and to connect the DTRS units to each other. If

the use of cables other than TASCAM cables causes or

results in damage to the units, the warranty is voided.

If a DTRS unit other than a DA-98 is used as a master unit,

the automatic Output TC Source function and Timecode

Offset functions of the DA-98 may not work correctly (see

the DA-98 Owner’s Manual, 10.5 and 13.2). In additoin,

remote control operation may not work correctly.

No power connection is needed for the RC-898.

All power for the operation of the RC-898 is sup-

plied by the first DTRS unit.

If the DTRS units are DA-88s and DA-38s only, they may

be connected in any order.

However, if you are operating a mixed set of DA-38s, and

DA-88s fitted with the SY-88 synchronizer board, we sug-

gest that the SY-88-equipped DA-88 should follow the RC-

898, allowing it to serve as a timecode slave, and a DTRS

chase master for the DA-38s.

NOTE

The TASCAM TM-D8000 digital mixing console also

allows the control of DTRS units. However, it is not possi-

ble to use a TM-D8000 and RC-898 for control of DTRS

units in the same setup. Naturally, however, a TM-D8000

console can be used to mix the audio to and from DTRS

units controlled by an RC-898 unit.

Use the suppled cable to connect the RC-898 to

the REMOTE IN/SYNC IN of the first DTRS

unit, and a PW-88S cable to connect the SYNC

OUT of the first unit to the REMOTE IN/SYNC

IN of the next unit, and so on, until the terminator

3.1.1 Machine IDs

Set the machine IDs of the DTRS units so that the

IDs run in a sequence from the unit at the “head”

of the chain, closest to the RC-898 (lowest possi-

ble ID) to the “tail” unit (highest ID). There

should be no gaps in this sequence.

A DA-88 uses a rotary switch to set the ID and

uses 0 as the lowest ID, and a DA-38 or DA-98

uses software to make this setting, and uses 1 as

3.2 Connections (parallel

units)

The RC-898 allows control of a unit implementing

the Sony P2 protocol. This connection is made

through the EXT 2 serial port [43], using a serial

cable designed for this purpose. The pinout for

this connector is as follows:

The RC-898 allows transport control of a unit con-

nected to the EXT 1 parallel port. Before making

this connection, check the specifications of the

other unit to ensure that the control pins available

match those provided by the RC-898, as shown

below in 3.2.2, “Parallel control/GPI pinout”.

The RC-898 provides only transport control for a unit con-

etc. are not possible when using the EXT 1 parallel port.

If a passive unit that does not supply power to the

tally supply pin (8) is being used, switch 1

(TALLY POWER) of the RC-898 [45] must be set

on (down) to allow the RC-898 to provide this

power.

Make the connection using a cable designed for

RS-422 connection (check the pinout of your P2

device before making the connection). This

machine may now be controlled by the RC-898

when the E2 MACHINE indicator [8] is lit.

3.2.1 Connections (GPI event units)

The EXT 1 parallel port may also be used for the

purpose of controlling up to five GPI event-con-

trolled devices.

3.4 A note on system clocks

When working with many digital audio units, all

these units must be fed from the same clock

source (either word or video). If this is not done,

there is a risk that speakers, etc. may be damaged.

The way in which these devices may be triggered

from the RC-898 is explained in 9.2, “Controlling

GPI devices”.

Note that this clock master is entirely different

from the timecode master in a studio setup. It is

perfectly possible for a clock slave to be a time-

code master and vice versa.

Section 3.5 - Memory and batteries

3.5 Memory and batteries

As you have noticed, the RC-898 requires no

power supply of its own, drawing its power from

the DTRS units to which it is connected.

Location memories and configuration settings are

stored using a battery backup system. The battery

should provide power for several years of use.

When the battery eventually degrades to the point

where it cannot provide enough power to retain

settings, the message ^MemoryErrorwill

be shown on the diaply screen (this can be

removed by pressing the ESCAPE key).

When this message appears, all memories (loca-

tion memories and configuration settings) are

cleared and reset to the default settings.

If you see this message, contact your TASCAM

dealer for details of battery replacement. Do not

attempt to replace the battery by yourself.

In this menu, there are two editable fields, as you

will see if you move the cursor with the LEFT and

RIGHT cursor keys. The cursor changes so that

the field which is currently to be edited is high-

lighted by an underline cursor.

4.1 Navigation

The menus are arranged hierarchically, from a top

(master) menu, through to individual parameters.

The master “top” menu appears like this:

Select Menu Group

>0 1 2 3 4 5 6 7

The first editable field is the ^Fixfield, which

may be changed between the values of ^Fixand

Vari. The second field is the numerical field

which sets the amount of the varispeed as a per-

centage of normal speed. The values of both fields

are set with the UP and DOWN cursor keys.

The cursor is represented here by the >symbol.

Use the LEFT and RIGHT keys to move the cur-

sor along a row, and the UP and DOWN keys to

move it between rows.

As soon as a value is changed, it is set. There is no

need to press any key to confirm the entry.

To return to a level above the current level, press

the ESCAPE key. You can continue pressing the

ESCAPE key until the top menu is reached.

As the cursor moves over the menu group num-

bers, the bottom line of the screen will change to

show an abbreviated summary of the contents of

the menu group. In the example above, the con-

tents of the ⁰menu group are: track delay, track

copy settings, varispeed and the location pre-roll

setting.

NOTE

Note that the Machinevalue (i.e. which machine is

being controlled) cannot be set in this way (this is explained

in 4.3, “Selecting the unit controlled by the menus”).

When the cursor is over the menu group which

you wish to enter, press the SELECT key to enter

Some operations are only possible on certain

models of DTRS recorder. For instance, timecode

functions are only available on the DA-98 and

DA-88 units equipped with the SY-88 board, and

dithering is only possible with DA-38 and DA-98

units. If you attempt to perform an operation on a

4.4 Commonly-used menus

The F1 through F10 function keys [22] may be

used to recall the ten functions (menu screens)

that you use most often.

However, as you can see from the front panel of

the RC-898, the UP and DOWN keys have

another meaning when used in combination with

the SHIFT key [23], and they change to being

NEXT and PREVIOUS keys, allowing you to

select the next unit in the chain, or the previous

one, respectively.

When the SHIFT key [23] is held down, these

keys can be used as an additional ten function

keys; F11 through F20.

NOTE

The menu-to-key assignments made on the RC-898 are

entirely independent of any menu-to-key assignments made

on the RC-898.

NOTE

This selection has no effect on the transport or location sec-

tion of the RC-898 and vice versa. The unit shown on the

MACHINE indicator [8] selected with the MACHINE key

The RC-898 allows you to store and recall almost

all parameters set using the menu system, so the

same remote control unit can be used with a vari-

ety of different equipment setups with the mini-

mum of reconfiguration.

F17 Abs Diff

This is a great time-saver, as not only are the RC-

898’s parameters stored and recalled, but the set-

tings for the DTRS units connected to the RC-898

are also stored and recalled. In this way, up to six

DTRS units can be reconfigured to preset configu-

ration patterns with the press of one key.

to select an individual unit, all DTRS units

connected to the RC-898 can be selected to

format tapes together.

5.1.1 Selecting the unit to which

operations refer

Generally speaking, the unit controlled by the

transport keys will be the first unit in the chain

(the other units in the chain are assumed to be

using the ABS chase protocol through DTRS

synchronization.

4) Move the cursor to the sampling frequency

field, and use the UP and DOWN keys to choose

between ^44.1and 48(kHz).

However, transport operations, etc. can also be

performed on individually-selected machines

other than the first one:

NOTE

If a digital signal is received at the DIGITAL IN connector

of the DTRS unit, and digital input has been selected (see

7.2.9, “Input selection”), the sampling frequency is decided

by the frequency of the incoming signal and cannot be

changed.

1) Press the MACHINE key [31].

The word MACHINE will start to flash in the

LOCATE TIME/VALUE

display [15].

5) Move the cursor to the “control” field and use

the UP key to change the setting from ^offto

tape from the beginning, you should wait until the

end of the tape before rewinding and ejecting it.

5.1.5 Transport controls

The RC-898 shares a common interface with all

DTRS units with regard to transport functions

(including entering end exiting record mode).

Consult the relevant portions of the DTRS unit

manual if you are unsure of the way in which

transport operations are carried out.

NOTES

The display shows a negative ABS time for a few seconds at

the beginning of the tape. While a negative time is shown,

no audio can be recorded on the tape.

We suggest that you leave a blank header of at least 30 sec-

onds at the beginning of the tape. This can be marked as a

virtual “zero point” if you like (see 6.3, “Setting a relative

time reference”).

One exception to this is the LOC key [41] which

does not appear on the front panel of DTRS units.

It is used to locate the tape to the value shown on

the LOCATE TIME/VALUE display [15]. For full

details of how this key is used and the location

facilities available from the RC-898, see 6, “Loca-

tion functions”.

5.1.3 Arming tracks

The tracks of the DTRS units are armed using the

REC FUNCTION keys with their indicators.

These keys and indicators only work for tracks of

units that are actually connected.

5.1.6 Shuttle mode

The RC-898 incorporates a jog dial and shuttle

wheel to allow precise positioning of the tape in

the DTRS units.

NOTE

When the DATA INC/DEC indicator [27] is not

lit, moving either of these controls will control the

selected unit(s) appropriately.

Before recording, you should make sure that either digital or

analog inputs, as required, have been selected (see 7.2.9,

“Input selection”) and the appropriate clock settings have

been made (see 7.2.6, “Clock selection”).

NOTE

Armed tracks, i.e. those which are ready for

When the currently-selected unit is recording, the jog and

shuttle controls are disabled (this prevents accidental inter-

ruption of a take).

recording, are shown by their indicators flashing.

Tracks which are actually recording are shown by

their indicators being steadily lit.

The indicators will go out 10 seconds after the

jog/shuttle controls are last used.

When a DA-88 or DA-38 track is recording, the

INPUT MONITOR indicator will light, showing

that the monitoring for the tracks is from the input

source, rather than being off-tape. The INPUT

MONITOR keys are not operational with a DA-88

or DA-38 unit.

The shuttle wheel allows forward motion at the

following speeds (relative to normal speed): 8 x,

4 x, 2 x, 1 x, 1/2, 1/4. The same speeds, except for

1 x, are available in reverse mode. The further the

shuttle wheel is turned away from the center posi-

tion in either the clockwise or counterclockwise

direction, the faster the tape will be moved.

When operating a DA-98 unit, the INPUT MONI-

TOR keys are operational, and can be used to

change between off-tape and source monitoring.

The jog dial allows very precise positioning of the

tape to frame accuracy.

5.1.4 ALL SAFE

Monitoring during shuttling is explained below

(see 5.2.3, “Shuttle monitoring”).

The ALL SAFE key [3] prevents accidental arm-

ing of tracks. When lit, all REC FUNCTION indi-

cators go out, and the keys of both the RC-898 and

the DTRS unit or units (see 7.2.2, “Key Mode”

below) are locked (pressing them will not arm

tracks).

5.2 Monitoring

The monitoring of off-tape and input source sig-

nals is complex, and varies a little between the

DA-88 and DA-38 units, and the DA-98 units, due

to the latter being provided with track-by-track

switching facilities between source and off-tape

monitoring, as well as the confidence mode

method of off-tape monitoring while recording

(see 7.2.12, “Confidence mode”).

When the ALL SAFE key is pressed to turn off

the safe operation, the arming status of all tracks

will return to what it was before the ALL SAFE

key was pressed.

little time by ignoring the “frames” field when

entering and locating to location memories.

6 – Location functions

NOTE

The RC-898 can store and recall up to 100 loca-

tion memory positions, allowing you to find key

points in a recording project easily.

The location and synchronization accuracy is not affected

by this function.

The contents of location memories (timecode val-

ues) are displayed on the LOCATE TIME/VALUE

LED display [15], and the number of the current

location memory is displayed on the MEMORY

NO. 2-digit LED display [14].

Accordingly, the RC-898 provides you with a way

to do this:

1) From the F menu group, move the cursor to

FrameDispand press SELECT:

6.1 Reference modes

Frame Display

Before proceeding with an explanation of the way

in which location operations are carried out, it is

necessary to examine the way in which times are

displayed on the RC-898.

The RC-898 can use one of three time reference

modes to show the tape times of the DTRS units

connected to it, as shown on the timecode indica-

tors [12]: ABS, REL and TC.

2) Use the UP or DOWN key to change from ^on

to ^off.

When frame display is set on, the last two digits

of the display will be used for the frames field of

location memories, and the RC-898 expects frames

to be entered as part of time values. When set to

off, the frames field is ignored (i.e. always

assumed to be zero).

ABS refers to the absolute time, as determined

from the servo track of the DTRS tape.

TC refers to timecode read from the timecode

track of the DTRS unit. However, since the RC-

898 does not accept timecode directly, this need

not be actual timecode, but in the case of a DA-98

or DA-88, may be pseudo-timecode, “synthe-

sized” from the ABS values (see 8.1.2, “Synthe-

sizing timecode from ABS times”).

6.3 Setting a relative time

reference

This operation is equivalent to pressing the “reset”

button on a numerical tape counter to set the value

to “0000”. When the RC-898 is in relative mode,

the time shown on the TAPE TIME display [13]

becomes relative to a zero point which you set.

This zero point is referenced to the first DTRS

unit in the chain.

REL refers to the time value, relative to a user-

defined reference point (see 6.3, “Setting a relative

time reference”).

Cue points may be set “on-the-fly” or entered

manually, and copied from a cue list. All cue

points may be edited and “trimmed” to frame

accuracy.

1) From the F menu group, move the cursor to

DispTimeand press SELECT:

For faster entry and editing, cue points may

optionally be displayed and edited to second accu-

racy, ignoring the “frames” field.

6.2 Setting the precision

Absolute

The RC-898 typically displays to frame-based

precision (although in fact, the location and syn-

chronization is to sample precision).

2) Use the UP or DOWN key to change

Absoluteto Relative.

However, it is not always necessary to work to this

degree of accuracy, and you may want to save a

followed by ENTER/LOAD.

The current time value from the first DTRS unit

will be displayed on the LOCATE TIME/VALUE

display [15].

The LOCATE TIME/VALUE display will now

show the actual time value of the “zero point”.

3) Press the LOC key [41].

4) Press the STR key [17].

The tape will return to the nominal “zero point”

and the TAPE TIME display will show

00:00:00:00.

The MEMORY NO. display [14] will start to flash.

5) Press the numeric keypad’s 0 key, and then

press the ENTER/LOAD key [20] to enter the

current time into the 00 location memory.

6.4 ABS setting

The ABS setting allows you to use the subcode on

the servo track of the DTRS unit as the time refer-

ence of the RC-898. Usually, this starts at

00:00:00:00, and continues for the length of

the tape.

The TAPE TIME display will now show

00:00:00:00, showing that it is now at zero,

relative to the time you have just captured.

If the display shows something other than

00:00:00:00, this means that the tape is now at

a position other than the point where you captured

the time (i.e. the tape was playing or recording).

However, there are some options available with

the ABS mode, which increase the flexibility of

the system. These are described in 8.1.2, “Synthe-

sizing timecode from ABS times”, and allow you

to start with an offset, etc. when synsthesizing

timecode.

All times now are relative to this time. Any loca-

tions will now be shown on the TAPE TIME dis-

play relative to the new 00 memory. For example,

if the relative “zero point” is set to

6.4.1 A note on ABS frame rate

00:30:00:00, when the tape is at the absolute

location of 00:45:00:00, the value shown on

the TAPE TIME display will be 00:15:00:00

(45 – 30). However, even though the value shown

on the TAPE TIME display changes, neither the

actual tape position nor values shown on the

LOCATE TIME/VALUE display are affected.

When ABS is selected, the number of frames per

second is different from that in any timecode

mode. For details of setting SMPTE/EBU frame

rates, see 8.1.3, “Selecting a timecode type”.

Timecode (whether SMPTE or EBU) contains a

fixed number of frames per second. However, the

ABS method of timing works in a slightly differ-

ent way.

Absolute settings

A minus value is shown on the displays either

with a leading minus sign (–) on the TAPE TIME

display, or with a leading period (.) on the

LOCATE TIME/VALUE display.

This pattern is repeated every three seconds, as

you will notice when you set frame values using

the menu system in ABS mode. When multiple

DTRS units are connected together in DTRS sync

mode, the master unit always outputs ABS tim-

ings to the slave unit(s).

6.3.1 “Return-to-zero”

Since the RC-898 works on time-based, rather

than counter-based, references, there is no dedi-

cated “RTZ” control. However, you can return to

the zero point using the following procedure:

6.4.2 Selecting Time Mode

may also be used to control the chase mode of the DTRS

units as described in 8.1.8, “Chasing to external timecode”.

NOTES

The values set here apply to the RC-898 location functions,

and are not affect settings made on the DTRS units con-

nected to the RC-898.

6.5 Location operations

The values set here do not apply to the auto-punch operation

pre-roll time, which is set using a separate menu (see 6.7.5,

“Setting pre-roll and post-roll times”).

Location transport operations on the RC-898 are

mainly controlled using the LOC key [41]. This

key, which has no equivalent on the DTRS units,

allows the instant location of the tape to the value

shown in the LOCATE TIME/VALUE display.

6.5.2 Auto play

When the DTRS unit reaches the location point, it

will normally go into stop mode.

However, it is also possible to set a locate pre-roll

time, and if this is set to a non-zero value, locating

to a position will move the tape to the time shown

in the display, minus the pre-roll value.

However, if the AUTO PLAY indicator [33] is on,

the unit will automatically start playing when the

location point is reached.

For example, if the pre-roll time is set to 5 sec-

onds, and the time shown in the LOCATE TIME/

VALUE display is 01:23:03:02, when the

LOC key is pressed, the tape will locate to

01:22:58:02. This allows time for cueing,

slave unit lock-up, etc.

6.5.3 “Instant” location

If you are playing back or recording, and you wish

to mark a point for later one-time location:

1) Press the CAPTURE key [29] at the point

where you wish to return.

2) At any point following the capture, press the

LOC key to return to the location point that has

just been captured.

NOTE

In the following explanations, in the interests of clarity and

brevity, we will refer to the units locating to the location

time. This should always be assumed to be the location time

minus the location offset, unless specifically mentioned

otherwise.

It is not necessary to stop the tape before pressing

LOC

. Location can be performed while the unit’s

transport is in any mode, including fast forward

and rewind.

6.5.1 Setting the location pre-roll value

You can now “fine-tune” this time value (see 6.5.5,

“Editing a location”). This location point may also

be stored in a location memory (see 6.5.6, “Storing

To set the pre-roll value which will be used by

location operations:

Section 6.5 - Location operations

the location in a memory”) and recalled for later

use.

6.5.6 Storing the location in a memory

There are 100 memories into which location time

values may be stored, numbered from 00 to 99.

6.5.4 Manual entry of a location point

You can also use the numeric keypad to enter a

time value manually from a cue list, etc. to which

you can locate.

The location memory which is currently in used is

shown in the 2-digit MEMORY NO. display [14].

As mentioned above (6.3, “Setting a relative time

reference”), location 00 is used for special pur-

poses, such as storing the “zero” reference point in

relative time mode. We therefore suggest that you

do not use location memory 00 as a general loca-

tion point.

Time values are entered from the right of the dis-

play, which is cleared as soon as a number key is

pressed. For instance, to enter a value of

01:25:34:12, the following keys should be

pressed:

00:00:00:01 (display is cleared and

starts flashing)

NOTE

00:00:12:53

00:01:25:34

00:12:53:41

01:25:34:12

Location memories stored on the RC-898 are completely

independent of either the MEMO 1 and MEMO 2 points

stored in the DTRS units, or of the 10 extra memory loca-

tions which may be stored in a DA-98 unit.

1) Enter or capture a location time (you do not

need to press ENTER in this case).

ENTER/LOAD (stops display flashing and enters the

value)

2) Press the STR key [17].

Note that the ENTER/LOAD key [20] is used to

confirm the entry.

The LOCATE TIME/VALUE display will stop

flashing, and the MEMORY NO. display [14] will

start to flash.

If you make a mistake entering the value, you can

stop the entry procedure with the CANCEL key

[19]. The display will stop flashing.

3) Use the numeric keypad [16] to enter the

number of the location memory into which you

want to store the value.

This time value can now be used for “instant”

location (simply press the LOC key [41]) or

stored in a location memory for further use (see

6.5.6, “Storing the location in a memory”).

The number will “fill up” from the right. If you

want to store the time value in memory 03, for

example, you only need to press the 3 key, but if

you want to store it in memory 13, press the 1 key,

followed by the 3 key.

6.5.5 Editing a location

When a location has been captured or entered as

described above, it can be edited using the jog dial

[28].

You can also use the JOG dial as a data dial (when

the DATA INC/DEC indicator [27] is lit) to select

the location memory.

1) Ensure that the DATA INC/DEC indicator [27]

4) Press the ENTER/LOAD key [20].

is lit.

The MEMORY NO. display will stop flashing, and

the value is stored in the location memory.

If this indicator is not lit, the JOG dial will control

the tape transport.

If you enter the wrong location memory, press the

CANCEL [19] key. The MEMORY NO. display

will stop flashing and will return to its previous

value.

2) Use the JOG dial to adjust the value of the

location point.

3) To confirm this edited value, either locate to the

position that you have just edited, or store the

edited value into the location memory.

6.5.7 Recalling a location memory

To recall and locate to a time value stored in a

location memory:

4) To use the JOG dial as a transport control

again, press the DATA INC/DEC key so that the

indicator goes out.

1) Press the RCL key [18].

The MEMORY NO. display [14] will start to flash.

which may have been entered accidentally. See

6.7.4, “Undo function” for details. Note that there

is no “redo” function available.

The number will “fill up” from the right. If you

want to recall memory 03, for example, you only

need to press the 3 key, but if you want to recall

memory 13, press the 1 key, followed by the 3

key.

6.5.9 Editing a location memory

When a memory has been recalled, it is possible to

edit it, either by replacing the contents with a

value entered from the numeric keypad or using

the jog/shuttle controls:

3) Press the ENTER/LOAD key [20].

The MEMORY NO. display will stop flashing, and

the time value stored in that memory will appear

on the LOCATE TIME/VALUE display.

1) Use the DATA INC/DEC key [27] to set the jog/

shuttle controls into data editing mode.

4) Press the LOC key [41].

2) Use the JOG dial [28] to “nudge” the values

displayed on the LOCATE TIME/VALUE

display [15].

The tape will locate to the location point that has

just been recalled.

If you enter a location memory in which nothing

has been stored, this is not an error, but the

LOCATE TIME/VALUE display will show

00:00:00:00.

The value will flash.

3) Confirm the entry with the STR key [17].

The LOCATE TIME/VALUE display will stop

flashing, and the MEMORY NO. display [14] will

start to flash.

If you enter the wrong location memory, press the

CANCEL [19] key. The MEMORY NO. display

will stop flashing and return to its previous value..

4) Press the ENTER/LOAD key to store the edited

value to the same location memory, or the

numeric keypad, followed by the ENTER/

LOAD key to store the edited value to a

different location.

6.5.8 Repeated entry of location points

You can also use the CUE STR key [39] to store a

series of location points as a tape is played.

1) Recall a location memory.

The location memory immediately after the

recalled memory will be overwritten, so make sure

that it is a location you do not want to keep.

6.6 Repeating a section

You can set two points, independently of the loca-

tion memories, which allow you to repeat play-

back continuously between them.

2) Start playing (or recording) the tape.

The order of steps 1) and 2) can be reversed.

NOTE

3) Press the CUE STR key.

The current tape location will be stored into the

location memory following the one you have just

recalled. No confirmation is necessary.

The points that are set here using the RC-898 are indepen-

dent of any repeat points set on the DTRS units. When

repeat times are set using the RC-898, the repeat function is

not available from the DTRS front panel.

The LOCATE TIME/VALUE display will now

show the value of the time just stored in the loca-

tion memory, and the MEMORY NO. display will

show the memory number in which it has been

stored.

1) From menu group 3, move the cursor to

The punch points can be checked and recalled in

the same way as any other location memory.

Alternatively, you can use the numeric keypad to

set the time value.

1) Press the RCL key.

The MEMORY NO. display will start to flash.

4) Move the cursor to the Startparameter,

and press the UP key to select the ^End

parameter.

2) Press either the IN or the OUT key, as

appropriate.

5) Set the time values for the ^Endpoint.

The time value of the punch-in or the punch-out

point will be shown on the LOCATE TIME/

VALUE display.

6) Press the REPEAT key (the indicator will light)

to start the repeat between the two points.

•

The LOC key can be now be used for instant

location to the punch-in or punch-out point.

The ^Startand ^Endtimes must be at least 5

seconds apart, otherwise repeat play cannot take

place.

The PRRL key [34] will also locate to the pre-

roll time minus the punch pre-roll time (see

6.7.5, “Setting pre-roll and post-roll times” for

details of setting this value). This is indepen-

dent of the location pre-roll time (see 6.5.1,

“Setting the location pre-roll value”).

If the ^Endtime is set, and the ^Starttime is

set to a time after the ^Endtime, when the

REPEAT key is pressed, the two time points will

be swapped, so that the ^Startcomes before the

^End.

In addition to checking the actual punch positions,

you can also check the length of the punch time:

When you are editing the repeat times, the DTRS

unit tries to take into account the fact that the

^Endshould follow the ^Start, and automati-

cally attempts to adjust the entries as they are

made so that they are consistent.

1) Press the RCL key.

The MEMORY NO. display will start to flash.

2) Press and hold down the IN key.

While the LOCATE TIME/VALUE display is

flashing, press the IN or OUT key as appropri-

ate. The display will stop flashing, and the

MEMORY NO. display will show in or ot,

depending on whether the value has been

stored as the punch-in or punch-out point.

2) If the DATA INC/DEC indicator [27] is not lit,

press the DATA INC/DEC key so that the

indicator is lit.

3) Use the JOG dial to adjust the value of the

punch-in or punch-out point.

4) After adjusting the value, press the IN or the

OUT key as appropriate to store the new value

into the punch memory.

NOTE

Setting a punch-out time which comes before the punch-in

time is meaningless, and will not be automatically corrected

by the RC-898. If you try to perform a punch operation with

the punch points set in this way, the tape will locate to the

punch-in point (minus the punch pre-roll time) and then

stop.

6.7.4 Undo function

If you have stored a punch in or out value and

overwritten it in error, there is an “undo” function,

ples, or advanced relative to other tracks up to a

value of 200 samples.

5) If you prefer to work in sample values, rather

than milliseconds, move the cursor to the

You can also use the cursor keys to enter a value

directly on the display screen.

2) Use the UP or DOWN key to select between

Alland Individual.

If you select ^Individual, only that unit cur-

rently selected for control (see 5.1.1, “Selecting

the unit to which operations refer”) will be con-

trolled by the three keys mentioned above. If you

select ^All, then all DTRS units connected will

respond to the commands of the ALL SAFE, ALL

INPUT and AUTO MON keys.

NOTE

There is an “invisible” field immediately to the right of the

frames field. If you place the cursor there and increment or

decrement the value, you can change the time as a whole (as

the frame field passes its maximum value, the seconds field

will increment).

The Auto Offset function described below can also

be used to set the offset.

7.2.3 Chasing with an offset

It is not always required that the DTRS units are in

perfect synchronization with each other.

4) Transfer the value to the display screen by

pressing and holding down the SHIFT key [23]

and pressing the ENTER/LOAD key [20].

For instance, it may be that three DTRS units are

being used for video post-production purposes.

The dialog and Foley tracks of a project have been

recorded on one DTRS tape (up to eight tracks),

and the backing music has been recorded on two

more tapes (16 tracks). Obviously, the units

replaying the two music tapes should be synchro-

nized to each other, but the music may need to be

“slipped” relative to the dialog and Foley unit

(which is, in turn, synchronized to the timecode

on the video, as described in 8.1.8, “Chasing to

external timecode”).

5) Use the SHIFT and UP (NEXT) keys to select

any other units which will chase with an offset.

When the master DTRS unit plays, the slave units

should now chase at the offset value you have set

up.

If an offset value is set on any unit or units, and

the Time Mode is set to ABS, the OFFSET indi-

cator [10] will light.

If you need to “fine-tune” these values, you can

use the UP and DOWN keys to adjust the value of

8.1.2 Synthesizing timecode from ABS

times

98 88

This section describes the timecode-based

functions available through the RC-898. Note that

while the RC-898 contains no timecode generator

or reader of its own, it is able to control the time-

code generators and synchronization facilities of

DA-98 and DA-88/SY-88 units. Since the DA-38

does not have any timecode facilities, this section

does not have any relevance if you are using a

setup composed of only DA-38 units.

98 88

As mentioned earlier, linear timecode

does not necessarily have to be striped on a tape

for the DTRS unit to be able to use the TC setting.

The subcode can be used to synthesize timecode,

eliminating the need to pre-stripe the tape for

timecode-based work.

In addition, the DA-98 can add offsets to the

ABS value, so that the timecode values can start at

any desired position, or can create a repeating

timecode pattern for tracks of nominal 10 or 20

minutes’ duration. See also 10.2.3 and 10.2.4 of

the DA-98 manual for further details.

Note that in this section, we use the term “time-

code” to refer to SMPTE/EBU timecode rather

than to ABS timecode.

When using a chain of DTRS units which are to

be synchronized to external timecode, you will

usually need to synchronize the first unit in the

chain. The other units should then chase to the

first, using the DTRSABS synchronization facil-

ity. For information related to this and to other

non-timecode-related synchronization features,

If the timecode on the DTRS unit matches the

DTRS tapes contain a video soundtrack and have

been striped either concurrently with, or from the

video tape), there is no need for an offset.

01:01:22:03

30DF

The bottom line of the display shows the current

timecode value being output from the tape. If the

tape is stopped, the last timecode read from tape

will be shown.

If, however, the DTRS tracks are not linked in this

way with the master source, an offset is required.

The offset can be ±12 hours from the received

timecode. Timecode “wraps” in a 24-hour clock

format, so that 12 hours in advance of 13:00:00:00

is 01:00:00:00, and 12 hours behind 02:00:00:00

is 14:00:00:00.

External timecode, if it is being used for recording

or for synchronization purposes, can be read in the

same way, except that the cursor should be moved

to Ext TCin menu group E.

8.1.8 Chasing to external timecode

When chasing to an external timecode source

(remember that you cannot chase to MTC), there

are two cases to be considered. The first is when

the DTRS unit which will be chasing timecode is

the first unit in the chain. In this case, there is no

DTRS sync signal received at the SYNC IN con-

nector (of course, the RC-898 provides control

signals), and hence, pressing the CHASE key [32]

will automatically synchronize the DTRS unit to

the incoming timecode.

1) From menu group 4, move the cursor to ^TC

^Offsetand press SELECT:

Timecode Offset

Machine

+00:00:00:00.00 30DF

Note that this setting is made to subframe accu-

racy. The timecode type will be shown in the bot-

tom right of the display screen.

The reference to which the incoming timecode is

matched, however, depends on the ^Time

^Modesettings of the DTRS unit with regard to

ABS or timecode (see 6.4.2, “Selecting Time

Mode”).

2) Use the numeric keypad to set the offset (use

the +/- key to change values between positive

and negative).

The value will be shown in the LOCATE TIME/

VALUE display and the OFFSET indicator [10]

will light.

In the case of a unit which is connected to the

master DTRS unit in the chain, the situation is a

little more complex, as the unit must be set up to

slave to incoming timecode rather than the DTRS

sync signals. Here, the ^{Time Mode}menu is

used once again (6.4.2, “Selecting Time Mode”),

but here it determines the chase sync source; time-

code or ABS sync.

If an offset value is set on any unit or units and the

Time Mode is set to TC, the OFFSET indicator

[10] will light.

As an alternative to using the numeric keypad, you

may also use the cursor keys to enter values

directly into the LCD display.

Note that it is unlikely that you will need to syn-

chronize a slave unit with timecode—typically,

only the first unit in the chain will be a timecode

slave, and this will act as a DTRS sync master for

the other units in the chain.

first clock setting (i.e. units 2 and 3 cannot have

their clocks set using the function described in

7.2.6, “Clock selection”), and the fourth unit can

have its clock set independently of the other three.

put, starting at the frame which has just been read.

Secondly, you can choose a “leap” option, in

which timecode is continuously output, but not

consecutively (the values between frames will

leap as the tape is read). The last mode is “off”, in

which case, no timecode will be output in fast

transport modes. See section 10.4.3 of the DA-98

manual for further details of this facility.

The park position allows you to set a pre-

roll position automatically on a DA-98 slaved to a

master timecode source. This gives the master unit

time to start playing timecode after starting to

play, and provides optimal lock-up when locating

and chasing external timecode. See sections

10.7.6 and 10.7.7 of the DA-98 manual for further

details of this function.

VIDEO IN terminal. This means that the time-

code frame boundaries will be aligned with the

frame boundaries as received in the video signal.

2) Play and stop the master unit.

3) If chase mode is off on the slave DA-98, turn it

on.

This is a completely different function to the syn-

chronization of the word clock to video (see 7.2.6,

“Clock selection”).

4) Use the UP or DOWN key to turn the ^TEST

from ^offto on.

In addition, if video resolve is enabled, the unit

can be set to track the frame boundaries constantly

and rechase if it drops out of sync (re-sync), or can

be set to a “lock and forget” mode (free), in a sim-

ilar way to the rechase options available for time-

code (see 8.2.5, “Rechase mode”). In re-sync

mode, output will be muted while the unit changes

speed to match frame boundaries.

The DA-98 will now start to rewind so that the rel-

ative difference is zero. Wait until the DA-98 tape

has stopped before proceeding with the next

step.

5) Play the master unit.

The park position value shown in the display

screen will change as the park position is calcu-

lated. Wait until the value has stabilized before

proceeding to the next step.

4) Move the cursor to the Widthfield and use

the UP and DOWN keys to select the pulse

NOTE

The minimum value for the pulse width is 0 ms,

and the maximum is 990 ms, settable in 10ms

increments.

The RC-898 provides only transport control for a unit con-

nected to the parallel port. Functions such as track arming,

etc. are not possible when using the EXT 1 parallel port.

Most GPI units require a trigger width of 200 ms.

If you are unsure of the trigger width for a particu-

lar device, we suggest that you try this value first

of all.

9.2 Controlling GPI devices

Up to five GPI devices may be connected to the

EXT 1 port. These devices may be triggered at set

times, based on the times received for display on

the TAPE TIME display of the RC-898.

NOTE

Note that the polarity setting here is also used as the polarity

setting for transport control signals sent to the E1 parallel

port device (see 9.1, “Controlling the parallel port

device”. In this case, the pulse width is fixed at 500 ms.)

Refer to the documentation supplied with any

units to be controlled by GPI to find out whether

the unit requires the controlling circuit to be

closed or open in order to trigger the event, and

the time of the pulse needed to act as a trigger.

9.2.2 Setting the trigger points

The location memories also serve as GPI trigger

points, when GPI devices are connected to the

EXT 1 port.

The wiring for the parallel port when used with

GPI devices is given in 3.2.2, “Parallel control/

GPI pinout”.

Since up to 10 GPI events can be associated with

location memories, we suggest the following

method of working:

NOTE

Since the GPI event timings are based on the information

transmitted from the DTRS recorders connected to the RC-

898, the timing may “slip” by up to one frame.

•

Use a “block” of location memories for this

purpose, starting at a number such as 80 or 90.

NOTE

While playing back the program material

which will be used with the GPI events, use the

CUE STR key [39] to add repeated cue points

to the list, as described in 6.5.8, “Repeated

entry of location points”.

ory is selected, the event will be turned off.

Alternatively, key in these cue points manually

from a cue list.

The EXT 2 9-pin serial connector [43] of the RC-

898 is used for RS-422 control of suitably-

equipped devices (Sony P2 protocol). As an exam-

ple of how this may be used, if you connect the

master VTR to the EXT 2 port, you can use the

RC-898 to control the whole system.

Adjust the fine timing of these trigger points

using the jog dial, if necessary.

Of course, there is nothing to prevent you from

using existing location memories for GPI triggers,

but you may find it easier to work with a series of

events dedicated to this purpose.

for the DTRS slaves. These DTRS slaves will be

used for recording, but the VTR will not (other-

wise the worktape will be erased!). The RC-898

therefore provides you with a “split mode” in

which all transport keys except the RECORD key

and the REC FUNCTION keys control the VTR,

and the recording keys control the DTRS units.

9.3.3 Serial unit timing source

The RS-422 device can be set to accept its timing

signals from either external timecode, or from the

Timer 1 internal time source (the video CTL sub-

code track).

In this way, all recording operations, including

auto-punch operations, can be carried out on the

DTRS units without the risk of accidentally eras-

ing the VTR tape.

However, there is one function where operation is

slightly different, and this is “on-the-fly” punch-

ing. Usually, when DTRS tracks have been armed,

and the tape is being played, pressing RECORD

will drop the tracks into record mode, and press-

ing PLAY will drop them out into play mode. In

split mode, this is not possible, since the PLAY

key controls the VTR.

98 When the track arming and recording of a

DA-98 unit is controlled by an external controller,

you can specify which tracks on the DA-98 corre-

spond to the tracks controlled by the controller

(for arming and recording purposes). The standard

video controller protocol (P2 protocol) allows for

control of up to eight digital and four analog audio

tracks. This function allows you to map DA-98

tracks to the “logical” tracks.

The following chart explains the relationship

between the serial unit, the split/normal mode, and

this function:

This mapping of DA-98 tracks to controller tracks

does not imply any correspondence between the

9.4.5 Device emulation

The DA-98 can emulate a variety of other

9.4.3 Timecode track mapping

devices, for example video recorders, etc., when

controlled by an editor (i.e. this setting determines

the way in which the DA-98 responds to a Device-

ID request).

This function is related to the track mapping

function described above. Analog track 3 in the

controller mapping is traditionally used as the

timecode track. To map this track to the audio

track selected above (see 9.4.2, “Track mapping

functions”) or to the dedicated timecode track of

the DA-98:

2) Use the UP and DOWN keys to select the

appropriate setting for each connected DTRS

unit.

Selecting disablehere means that the track

referred to by the controller’s commands as “ana-

log 3” will be the DTRS track designated as “ana-

log 3” in the table above (9.4.2, “Track mapping

functions”). Selecting enablemeans that the

DA-98’s dedicated timecode track will be con-

trolled by commands addressed by the controller

to the “analog 3” track.

any other device from this list.

9.4.4 Remote track arming

It is sometimes useful to be able to disable

track arming of a DA-98 unit from a remote con-

troller, especially when that controller is a video

editor which only allows for the arming and con-

after the command is received from the editor (the

DA-98 begins recording immediately). Many edi-

When locating in 9-pin command mode, the

then enter pause mode.

2) Use the UP and DOWN keys to select a value

from between ⁰and 9frames, or Auto. The

value of the ^Autosetting depends on the

emulation selected (see 9.4.5, “Device

What is then returned to the controller can be

either a Stop message, for use with controllers

who will only issue their next command when a

Stop signal is received, or a Still message for use

with controllers which make a distinction between

pause and Stop (e.g. LYNX II and Microlynx syn-

chronizers).
