The MT109-100 has 8 external inputs, 1 internal input, and 1 output. The internal inputs come from an
Expansion card using a 10-pin IDC cable connected between P12s of the Expansion and Master cards.
The internal input is configured as input 7 or input 8. Only one of two internal inputs is used at a time
and it depends on how the jumpers on the Expansion are set. In order to use one of the internal inputs,
one of the external inputs (7 or 8) cannot be used.
Setting Jumpers:
1) As an Expansion card: set P13 as port 7 (L1E and R1E) or port 8 (L2E and R2E).
2) As a Master card: set jumpers on P23 and P24 as described below.
If the Expansion card's jumpers on P13 are set on L1E and R1E, the Master card must select internal
input 7 on P23 (L1E) and P24 (R1E).
If the Expansion card's jumpers on P13 are set on L2E and R2E, the Master card must select internal
input 8 on P23 (L2E) and P24 (R2E).
Note: The MT109-100 is an 8-In, 1-Out switcher. For a 15-In, 1-Out switcher, use two MT109-100
cards, one as a Master card and the other as an Expansion card. (See page 8.)

Step 1. Determine how the MT109-100 is going to
be configured. A standard MT109-100 is
an 8-In, 1-Out switcher, but two
MT109-100s (one Master and one
Expansion) may be configured as a
15-In, 1-Out switcher.
Step 8. The MT109-100 is now operational.
OPERATION
7
7.1 RS-232 CONTROL
In Application Diagram, DIAGRAM 4, on
page 8, the Master is set to accept 7
external inputs and 1 internal input. The
Expansion card has 8 external inputs
(inputs 8-15). For RS-232 commands, the
8 external inputs of the Expansion card
must still be configured as inputs 1-8.
The
MT109-100
has
many
advanced
remote-control capabilities accessible through
standard RS-232 communication. Control may be
accomplished through a computer control system
or any other device capable of sending RS-232
communication.
For example, if the Master is in slot 1 and
the Expansion card is in slot 2, select
inputs using the following commands:
7.1.1 RS-232 INTERFACE
The control commands for the MT109-100 are
in a simple ASCII character format.
To select input 1:
[ON1C1]
[ON2C1]
1. Square brackets “[ ]” are part of the
command.
2:
...
7:
[ON7C1]
2. Use uppercase letters for all commands.
To select input 8:
[ON8C1] [ON1C2]
[ON8C1] [ON2C2]
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
actions or request information from the card.
Some commands do both simultaneously.
9:
...
15: [ON8C1] [ON8C2]
Step 2. Turn off power to the MultiTasker system
and disconnect from AC power.
Step 3. Remove a slot cover (MT200-101) from
an unused slot. Identify the slot number
and note that it is for RS-232 control.
A command that instructs the card only to
perform an action will generate feedback of “[ ]”.
The open bracket immediately followed by a
close bracket indicates the card received a valid
Step 4. Slide the MT109-100 into an available slot
in the MultiTasker in order to connect to
the bus. Make sure that the MT109-100
fits into place and then secure the card by
tightening the retainer screws located on
the top and bottom of the card.
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]”.
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 5. Restore power to the MultiTasker system.
Step 6. The LED on the card panel will turn red
indicating the card is operational. An LED
that is blinking red indicates a problem. If
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
1. [VER]
Each command consists of three parts:
Function, Card ID, and Unit ID.
This command displays the software version
and card type for the card.
[ Function , Card ID , Unit ID ]
Command Format: [VERCnUi]
Example: [VERC3U2]
VER = Function
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
C3
U2
= Card ID or Group ID
Example:
= Unit ID (optional for Unit ID 0)
Send the command [VERC2] to check the
version of the MT109-100 in slot 2. The system
will return the following feedback:
For Function, see a detailed explanation under
each command description.
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.
[MT109-100 690-0179-006]
MT109-100 = card type
690-0179-006 = software version
2. [C]
This command displays the status of the card.
Command Format: [CnUi]
Card ID 0 (C0) is used for the controller and
cannot be reassigned.
Cn = card ID (n = # from 1 to max slots)
Ui = unit id (i = 0 to 9)
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.
Example:
An MT109-100 card is in slot 4. Sending the
command [C4] to the MultiTasker will yield
feedback similar to the following:
Changing the position of a card will significantly
affect the commands recorded on software
definitions or third-party control systems.

Example:
31. […F] – Feedback
The command [HELPC4] is sent to the card in
slot 4. Some of the data is displayed, but most
is missing. Send the [FBD1C4] to slow the rate
at which the card sends feedback to the system.
After processing a command, an OK or ER will
be returned as feedback if "F" is included at the
end of the command string.
32. […P] – Path
ID COMMANDS: RSI, SIDn, SIDnCi, SID+, RSN
This command sets the path for the output, but
is not active until the switch command, [SW], is
executed. Commands ending in "P" are not
executed immediately. The path for outputs on
one or more cards can be preloaded. See the
[SW] command for details.
The default Card ID is the card’s slot number.
The next several commands allow the ID to be
set 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.
33. [SW] – Switch
The switch command immediately connects
inputs and/or outputs, which were previously set
with the path command on this card and all
other cards in the system.
Some cards require more than one slot in the
MultiTasker system. As an example, some
matrix switcher cards require 4 slots. If there are
5 of these cards installed, they would be
numbered C4, C8, C12, C16 and C20.
Changing the Card ID allows the user to define
the cards as C1, C2, C3, C4 and C5.
Example:
There is an MT109-100 in slot 2 and another
MT109-100 in slot 3. Switch C2 to Input 1 at the
same time a switching C3 to Input 4 by sending
the following commands:
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.
[ON1C2P] [ON4C3P] [SW]
34. [TEST]
This command performs a series of tests on the
internal memory.
The ID commands work with all MultiTasker
Front Panel 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:
Upon completion, the system will display
"MEMORY IS GOOD" if all tests pass;
otherwise, failures will be indicated.
35. [FBD]
690-0122-019 = Version 019 or later.
690-0123-005 = Version 005 or later.
690-0124-019 = Version 019 or later.
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.
Send the command [VER] and verify the
feedback includes the following:
690-0122-019 690-0123-005 690-0124-019
Command Format: [FBDmCnUi]
Check the last three digits against the numbers
above to determine if the Card ID commands
can address all 99 Card IDs.
m = Delay (0= no delay, 1= delay 100mS)
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = from 0 to 9)

36. [RSI]
This command resets the card IDs in the
39. [SID+]
This command sets the Card ID of all the cards
in a system to their slot number plus the offset
value.
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.
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 sum of the slot number,
8, and the offset, 91, equals 99.
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.
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.
37. [SIDn]
This command sets all the cards installed in a
MultiTasker 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.
Connect the computer to the second unit only
and send [SID+20] to set the ID of all cards in
the enclosure to their slot number plus 20.
Reconnect both units to the computer.
Command Format: [SIDn]
n
= Card ID (n = # from 1 to 99)
Example:
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.
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.
40. [RSN]
38. [SIDnCi]
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.
This command sets the Card ID of a single card
to a number from 1 to 99.
Command Format: [SIDnCi]
Command Format: [RSNCi]
Ci = Card ID (i = # from 1 to 99)
Example:
n
= Card ID (n = # from 1 to 99)
Ci = Slot Number (i = # from 1 to max slots)
Example:
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:
Send the command [SID50C10] to set the ID of
the card in slot 10 to an ID of 50.

Example:
GROUP COMMANDS
Group 5 consists of the cards located in slots
numbered 2, 4, and 6. Remove just cards 4 and
6 from the group by sending the command
[RMC4C6G1]. The system will return the
following feedback:
The next few commands are group commands.
The use of groups allows several boards, with the
same functions, to be controlled simultaneously
with a single command. These commands apply to
all cards, not only the MT109-100.
[G5=C2]
42. [WR]
44. [RMG]
This command groups multiple cards in the

maximum of eight groups.
This command may be used to delete an entire
group, or all groups.
REMOVE A GROUP
Remove all the members from the group,
effectively deleting the group.
In systems with audio and video cards, the
cards are typically grouped as follows:
Command Format: [RMGkUi]
Gk = Group ID (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
Group 1 = Video Cards
Group 2 = Audio Cards
Group 3 = Video and Audio Cards
Command Format: [WRCn1Cn2…GkUi]
Cn = Card ID (n = slot # from 1 to max slots)
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Group 5 consists of the cards located in slots
number 2, 4 and 6. Remove all cards from the
group by sending the command [RMG5]. The
system will return the following feedback:
Example:
[G5=0]
Group cards 2, 4, and 6 as Group 5 of Unit ID 1
by sending [WRC2C4C6G5U1]. After executing
