Step 2. Slide the MT113-100/101 into an available
slot in the MultiTasker Enclosure in order
to connect to the bus. Make sure that the
MT113-100/101 card fits into place.
7.2 DESCRIPTION OF COMMANDS
Each command consists of three
Function, Card ID, and Unit ID.
[ Function , Card ID , Unit ID ]
Step 3. Secure the card to the MultiTasker by
tightening the retainer screws located on
the top and bottom of the MT113-100/101
card.
Example: [VERC3U2]
VER = Function
C3 = Card ID or Group ID
U2 = Unit ID
Step 4. Turn on power to the MultiTasker.
Step 5. The fan on the card will turn on.
For Function, see a detailed explanation under
each command description.
Step 6. Connect audio cables from the audio
source to the input connector of the
MT113-100/101. Connect the output
connectors of the MT113-100/101 to the
audio equipment through an audio cable.
The Card ID is an assigned value. It is equal to
the enclosure slot number in which the card is
installed. The value can range from 1 to 4 up to
1 to 20 depending on the enclosure.
Step 7. Starting from the left, identify the slot
number where the MT113-100/101 card is
plugged into the enclosure and note that it
is for RS-232 control.
OPERATION
Card ID 0 (C0) is used for the controller. See
the MT100-100 User’s Guide for details.
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.

7.1 RS-232 CONTROL
Changing the position of a card will significantly
affect the commands recorded on software
definitions or third party control systems.
The MT113-100/101 has many advanced remote
control capabilities, which are accessible through
standard RS-232 communication. The actual
controlling can be accomplished through a
computer control system or any other device
capable of sending RS-232 commands.
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.
7.1.1 RS-232 INTERFACE
The RS-232 commands, for the MT113-100/101

The following 7 commands are used to control the
output volume of the MT113-100/101. They may be
used with computer control, but also are designed
to be used with the {SETVK} command using keys
on the Front Panel. The following code sample sets
front panel keys 8 and 10 to Ramp Up and Ramp
Down respectively. See your Front Panel User’s
Guide for more details.
21. [MUT1]
This command disables the speaker output. It
does not affect the fixed output.
Command Format: [MUT1CnUi]
When defined as a volume control key, the key will
respond to two conditions: press and release.
Below, subroutine 8 starts ramping up when key 8
is pressed and subroutine 10 starts ramping down
when key 10 is pressed. Subroutine 108 stops
ramping when either key is released.
Cn = Card ID (n = slot # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
Turn off the speaker ports of the
MT113-100/101 in slot #4 by sending the
command [MUT1C4].
{WRS8=RUPC4}
{WRK8=8,108,0,0,0}
{WRS10=RDNC4}
{WRK10=10,108,0,0,0}
{WRS108=RSTC4}
{SETVK8}
{WRLK8=VOL_UP}
{SETVK10}
{WRLK10=VOL_DN}
[RAMP=10C4]
22. [CLR]
This command clears the card and resets it to
its factory defaults. All volume levels are set to
maximum, bass and treble are set to midrange,
loudness is turned off and mute is turned off.
Command Format: [CLRCnUi]
Cn = Card ID (n = slot # from 1 to max slots)
//Ramp Up
//Press= start, release= stop
//Ramp Down
//Press= start, release= stop
//STOP RAMPING
//Set key 8 as volume key
//Define Key 8 Label
//Set key 8 as volume key
//Define Key 8 Label
//Set the ramp rate.
23. [RUP]
Ui = Unit ID (i = # from 0 to 9)
This command ramps the OUTPUT volume to
its maximum level at the rate defined using the
[RAMP] command.
Example:
Clear the MT113-100/101 in slot #4 by sending
the command [CLRC4]. Send the status
command after the clear command and receive
the following feedback:
Command Format: [RUPCnUi]

MULTITASKER™
Example:
Example:
There is an MT113-100/101 in slot #5. Send the
command [RAMP=16C5] to set the ramp rate to
16 seconds. After this is set, any ramping will
occur at a rate of 16 steps in 16 seconds, or 1
second per step. Confirm the setting by sending
the command [RAMPC5] and receiving the
feedback:
The command [HELPC4] is sent to the card in
slot #4. Some of the HELP file is displayed on
the screen, but most is missing. Send the
command [FBD1C4] to slow down the rate at
which the card sends feedback to the system.
CARD ID COMMANDS
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.
RAMPTIME = 16 SECONDS
30. [TEST]
This command performs a test on the internal
memory. Upon completion, the system will
display the results. If there are no problems, the
system will display the following:
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 ID's greater than
the number of slots in the system:
MEMORY IS GOOD
Otherwise, failures will be indicated.
690-0122-019 = Version 019 or later.
Command Format: [TESTCnUi]
690-0123-005 = Version 005 or later.
Cn = Card ID (n = slot # from 1 to max slots)
690-0124-019 = Version 019 or later.
Ui = Unit ID (i = # from 0 to 9)
NOTE: In MTSetup, send the command [VER]
from the Terminal Window. The system will
respond with feedback similar to the following:
Example:
There is an MT113-100/101 in slot #10. In order
to test the internal memory, send the command
[TESTC10].
[690-0122-015 690-0123-005 690-0124-019]
Check the last three digits against the numbers
above to determine if the Card ID commands
can address all 99 Card ID's.
31. [FBD]
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.
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.
Command Format: [FBDmCnUi]
m
= Delay (0= no delay, 1= delay 100mS)
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.

32. [RSI]
35. [SID+]
This command resets the card ID's in the
system. After sending this command, each card
ID in the system will match the slot number of
the card. Use this command along with the SID
commands that follow. The [RSI] command
MUST be used prior to changing Card ID's once
they have already been set.
This command sets the ID of all the cards in a
system to their slot number plus an 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.
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.
Example:
There are two, 20 slot enclosures to be
connected together during normal operation.
The first unit will use the Card ID defaults which
are equal to their slot numbers. The second unit
will have the same Unit ID, but will have the
card ID's offset by 20.
33. [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.
Connect the computer to the second unit only.
Send the command [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)
The cards in the first unit will be referenced as
Card ID's 1-20 and the cards in the second unit
will be referenced by Card ID's 21-40.
Example:
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.
36. [RSN]
This command reads the slot number of the
card with a specified ID number, and returns the
value to the system to be displayed in the
terminal window. If more than one card has the
same ID, each slot number will be displayed.
34. [SIDnCi]
This command sets the Card ID of a single card
to a number from 1 to 99.
Command Format: [RSNCi]
Command Format: [SIDnCi]
n
Ci = Card ID (i = # from 1 to 99)
= Card ID (n = # from 1 to 99)
Example:
Ci = Slot Number (i = # from 1 to max slots)
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:
Example:
Send the command [SID50C10] to set the ID of
the card in slot #10 to an ID of 50.

39. [RMC]
Command Format: [HELPCnUi]
Ui = Unit ID (i = # from 0 to 9)
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.
Example:
Command Format: [RMCn1Cn2…GkUi]
In order to display the RS-232 commands
available for the MT113-100/101 card in slot #2,

Cn = Card ID (n = # from 1 to max slots)
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
38. [WR]
Group 1 consists of the cards located in slots
numbered 1, 2, 3, 4 and 5. Remove just cards
#4 and #5 from the group by sending the
command [RMC4C5G1]. The system will return
the following feedback:
This command groups multiple cards in the
enclosure allowing all the group members to be
controlled simultaneously with the same
command. Each unit may define a maximum of
eight groups.
G1=C1C2C3
In MultiTasker systems with audio and video
cards, boards are typically grouped as follows:
40. [RMG]
This command may be used to delete an entire
group, or all groups.
Group 1 = Video Cards
Group 2 = Audio Cards
Group 3 = Video and Audio Cards
REMOVE ONE GROUP MEMBERS
If assigning group commands to button
functions, it is best to use the "Press and Hold
on Power Up" to make group settings.
Remove all the members from the group,
effectively deleting the group.
Command Format: [WRCn1Cn2…GkUi]
Gk = Group number (k = # from 1-8)
Cn = Card ID (n = slot # from 1 to max slots)
Ui = Unit ID (i = # from 0-9)
Gk = Group number (k = # from 1-8)
Example:
Ui = Unit ID (i = # from 0-9)
Group 1 consists of the cards located in slots
number 1, 2 and 3. Remove all cards from the
