and disconnect from AC power.
Step 3. Remove a slot cover (MT200-101) from
one of the unused slots. Identify the slot
number and note that it is for RS-232
control.
7.1.1 RS-232 INTERFACE
Step 4. Slide the MT115-110 into the enclosure in
order to connect it to the bus. Make sure
the card fits into place and then secure
the card by tightening its retainer screws.
The control commands for the MT115-110 are in
a simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
Step 5. Restore power to the enclosure. The
2. Use uppercase letters for all commands.

LEDs for each input should be on and red.
Step 6. Connect the computer/component video
and audio sources to Inputs 1 and 2. If a
properly formatted input signal is
available, the Input LED will turn green.
The cards in a MultiTasker system are capable
of performing various functions, as well as
providing feedback to the user or control
system. Commands instruct a card to perform
specific actions or request information about the
status of the card. Some commands do both
simultaneously.
Step 7. Connect the 4TP OUT1 to the input of its
Twisted Pair receiver.
Step 8. Connect the 4TP OUT2 to the input of its
Twisted Pair receiver.
A command that instructs the card only to
perform an action will generate feedback of “[ ]”.
The open bracket immediately followed by a
closed bracket indicates the card received a
valid command. If the command requested
information from the card, the feedback
generated by the card is the acknowledgement
of having received a valid command. Invalid
commands generate feedback of “[ERR001]”.
Step 9. The MT115-110 is now ready for
operation.
Step 10. Video equalization is provided to fine-tune
the displayed image on the remote
display. The equalization adjustments on
the MT115-110 and Twisted Pair receiver
work together. Typically, for short cable
runs the equalization will be set to near
minimum. Cable lengths up to 400 ft
(122 m) will require near maximum
equalization on both units.
After processing a command, an “OK” or
[ERR001] will be returned as feedback if ‘F’ is
included at the end of a command string.
Step 11. The MT115-110 also has video gain
adjustment capability through RS-232
control. See the following section for
RS-232 command details.
Commands ending in ‘S’ will be saved into
memory. Commands not ending in ‘S’ will still be
executed, but will not be restored when the
system is reset or powered off, then on.

7.2 DESCRIPTION OF COMMANDS
COMMANDS
Each command consists of three parts:
Function, Card ID, and Unit ID.
1. [VER]
This command displays the software version
and card type for the MT115-110 card.
[ Function , Card ID , Unit ID ]
Example: [VERC3U2]
Command Format: [VERCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
VER= Function
C3 = Card ID or Group ID
U2 = Unit ID (optional for Unit ID 0)
An MT115-110 card is in slot 3. Send the
command [VERC3], and the system will return
feedback similar to the following:
For Function, see a detailed explanation under
each command description.
[MT115-110 690-0231-001 C03]
The card ID is a unique identifier. It is equal to
the enclosure slot number, or it may be an
assigned value. As the slot number, the value
can range from 1-4 up to 1-to-20 depending on
the enclosure. If the value is assigned, the ID
may be a maximum of 99. Card ID 0 (C0) is
used for the controller and cannot be
reassigned.
MT115-110
= Model number
690-0231-001 = Firmware version
C03
= Card ID
2. [C]
This command displays the status of the card.
Command Format: [Cn]
The group ID is a number representing a group
of cards defined with the [WR] command. When
using the group ID, all cards in the group will
perform the given instruction.
Cn = Card ID (n = # from 1 to max slots)
Example:
NOTE: In this manual, cards will be referenced
by their ID (C1, C2...C99). Typically, the ID
number will be equivalent to the slot number.
Groups will be referenced by their ID (G1-G8).
There is an MT115-110 card in slot 3. Sending
the command [C3] will yield feedback similar to
the following:
INPUT#1 VIDEO GAIN 4
EQUALIZATION 32
INPUT#2 VIDEO GAIN 4
EQUALIZATION 32
Changing the position of a card will significantly
affect the commands recorded on software
definitions or third-party control systems.
The unit ID has a value from 0 to 9. Unit ID 0
should be used for single unit operation. If the
unit ID is set to zero, each command may be
used without Ui. Use the command [SETU0], as
explained in the MT100-100 User’s Guide.
In this case, both card inputs are set for a video
gain of 4 and an equalization of 32.
If there is no card in slot 4, sending the [C4]
command will not return any feedback.
Example:
[VERC3]:
For Unit ID Zero
[VERC3Ui]: For Unit ID other than Zero
[VERC3]:
Equivalent to [VERC3U0]

setting for Input 1 will be displayed.
This command turns feedback delay on or off. It
is necessary when installing some newer cards
in older systems. If the system does not receive
all of the feedback from the card, the card may
be communicating too fast. This command will
slow down the card's communication rate.
[10]
Next, send the commands [-], [-], and [-] to
decrease the setting by 3. Send the [GAIN]
command again to display the new value.
[7]
Command Format: [FBDm]
m = Delay (0= no delay, 1= delay 100mS)
Example:
13. [GAIN=]
This command sets the gain level for an input to
a value specified by the user. A gain setting of 4
is equivalent to unity gain.
The command [HELPC3] is sent to the card in
slot 3. Some of the HELP file is displayed on the
screen, but most is missing. Send the command
[FBD1] to slow down the rate at which the card
sends feedback to the system.

17. [RSI]
ID COMMANDS
This command resets the card IDs in the
system. After sending this command, each card
ID in the system will match the slot number of
the card. If the card is moved to another slot, its
ID number will be the new slot number.
The default card ID is the same as the card slot
number. The next several commands allow the
user to change the card ID to a value other than
the slot number. Once the ID is changed,
moving the card to another slot will not change
the card ID. If a card in slot 4 is set to ID 1, then
moved to slot 10, its ID will remain 1. The RSI
command forces each installed card to take its
slot number as its ID number, regardless of the
slot in which it is installed.
Command Format: [RSI]
Example:
Send the command [RSI] to the system with
Unit ID 0. The card in slot 1 will have ID 1, the
card in slot 2 will have ID 2, and so on. If the
card in slot 1 is then moved to slot 4, the card ID
will then be 4.
Some cards require more than one slot in the
MultiTasker system. As an example, some
matrix switcher cards require 4 slots. If 5 of
these cards are installed, they would be
numbered C4, C8, C12, C16, and C20.
Changing the ID allows the user to define the
cards as C1, C2, C3, C4, and C5.
18. [SIDn]
This command sets all the cards installed in the
MultiTasker system to the same card ID. After
sending this command, all cards will be
addressed with the same ID. Use caution when
sending this command to a system with multiple
board types.
Another use for changing the card ID is to be
able to use multiple systems without having to
set each unit to a different unit ID. All systems
may be left as unit ID 0 for ease of
programming. The cards in the first unit may be
numbered 1-10 and in the second unit 11-20.
Command Format: [SIDn]
n
= Card ID (n = # from 1 to 99)
Example:
The ID commands work with all MultiTasker
systems. However, front panels that have
firmware releases prior to the following will not
be able to address card IDs greater than the
number of slots in the system:
Send the command [SID1] to the system. All the
cards in the system now have ID 1. Any
commands that are sent to card ID 1 will be
received and executed by each card.
690-0122-019 = Version 019 or later.
690-0123-005 = Version 005 or later.
690-0124-019 = Version 019 or later.
19. [SIDnCi]
This command sets the card ID of a single card
to a number from 1 to 99.
Command Format: [SIDnCi]
Send the command [VER], and the system will
respond with feedback that includes the
following:
n
= Card ID (n = # from 1 to 99)
Ci = Slot Number (i = # from 1 to max slots)
690-0122-019 690-0123-005 690-0124-019
Example:
Check the last three digits against the numbers
above to determine if the card ID commands
can address all 99 card IDs.
Send the command [SID50C10] to set the ID of
the card in slot 10 to an ID of 50.

20. [SID+]
This command sets the card ID of all the cards
GROUP COMMANDS
The next few commands are group commands.
The use of groups allows several cards with the
same functions to be controlled simultaneously
using a single command. Up to 8 groups
(G1-G8) may be defined in a MultiTasker
system. These commands apply to all cards,
not only the MT115-110.
in a system to their slot number plus the offset
value.
Command Format: [SID+n]
n = Offset amount (n = # from 0 to 99)
The maximum card ID is 99, so subtract
the highest slot number from 99 to find
the maximum offset. For example, in an
8-slot enclosure, the maximum offset
would be 91. The slot number (8) plus the
offset (91) equals 99.
22. [WR]
This command adds cards to a group allowing
all the group members to be controlled
simultaneously with the same commands. Each
MultiTasker unit may define a maximum of eight
groups.
Example:
There are two 20-slot enclosures to be
connected together during normal operation.
The first unit will use the default IDs where the
card ID is equal to the slot number. The second
unit will have the same unit ID, but each card ID
will be offset by 20.
In MultiTasker systems with audio and video
cards, the groups are typically as follows:
Group 1 = Video Cards
Group 2 = Audio Cards
Group 3 = Video and Audio Cards
Command Format: [WRCn1Cn2…Gk]
Cn = Card ID (n = slot # from 1 to max slots)
Gk = Group number (k = # from 1-8)
Example:
Connect the computer to the second unit only.
Send [SID+20] to set the ID of all the cards in
the second enclosure to their slot number plus
20. Reconnect both units to the computer.
The cards in the first unit will be referenced as
card IDs 1-20 and the cards in the second unit
will be referenced by card IDs 21-40.
Add C2, C4, and C6 to G5 by sending the
command [WRC2C4C6G5]. After executing this
command, C2, C4, and C6 will be G5. The
system will return the following feedback:
21. [RSN]
This command displays the slot number of a
card with a specified ID number. If more than
one card has the same ID, each slot number will
be displayed.
[G5=C2C4C6]
Now when a command is sent to G5, each
board in G5 will execute the same command.
Command Format: [RSNCi]
Ci = Card ID (i = # from 1 to 99)
Example:
23. [RMC]
This command may be used to remove one or
more group members from a group. Reset the
system after using this command for all changes
to take effect.
The card in slot 4 takes up four slots in the
enclosure. Its ID was set to 1 since it is the first
card installed in the system, reading from left to
right. Send the command [RSNC1] to find the
slot number of this card. The system responds
with the following feedback:
Command Format: [RMCn1Cn2…Gk]
Cn = Card ID (n= # from 1 to max slots)
Gk = Group ID (k = # from 1-8)

Example:
Command Format: [RDGk]
G5 consists of the C2, C4, and C6. Remove
only C4 and C6 from the group by sending the
command [RMC4C6G5]. The system will return
the following feedback:
Gk = Group ID (k = # from 1-8)
Example:
C2, C4, and C6 make up G5. Read the member
data for G5 by sending the command [RDG5].
The system will return feedback as follows:
[G5=C2]
24. [RMG]
[G5=C2C4C6]
This command may be used to delete an entire
group, or all groups.
The feedback shows G5 and then the cards that
make up G5. In this case, G5 includes C2, C4,
and C6.

1. In order to enter Menu Mode, the system
needs to be connected to a computer
running RS-232 control software.
7.4 MENU MODE
Menu Mode commands allow virtually the same
functionality as programming commands. Unlike
the programming commands in the previous
sections, menu commands prompt the user to
select from a list of available options. The system
then responds based upon selections made by the
user.
2. In the Terminal Window, press ENTER on
the keyboard.
3. The system interrogates all cards and
returns a list of cards and their ID numbers.
Example: 08: MT115-110
NOTE: Only cards supporting the menu
feature will be displayed.
The menu-driven commands are only available with
MultiTasker systems that have the following front
panel firmware:
4. Enter the 2-digit ID and a menu for the card
will be displayed. In the example above,
enter “08” for the MT115-110.
690-0122-015 = Version 015 or later.
690-0123-004 = Version 004 or later.
690-0124-018 = Version 018 or later.
WARNING: Do NOT enter any characters
except those relating to the desired menu.
Press ENTER after “08” and the original
prompt will be displayed.
Send the command [VER] and the system will
respond with feedback that includes the following:
690-0122-015 690-0123-004 690-0124-018
5. The system will prompt for selections
specific to the selected card.
Check the last three digits against the numbers
above to determine if Menu Mode is available.
6. Read each menu carefully, and continue
selecting keys as prompted for further
functions. (Example prompt: "Key= ")
