OPERATION  
7.1 RS-232 CONTROL  
The MT103-123  
remote-control capabilities accessible through  
standard RS-232 communication. Control may be  
accomplished through a computer, control system,  
or any device capable of RS-232 communication.  
7
Step 1. Determine the settings required for Gain,  
Sync-On-Green, Horizontal Sync Polarity,  
and Vertical Sync Polarity. If necessary to  
change the factory defaults, set the  
switches per Diagram 4 on page 8.  
has  
many  
advanced  
Step 2. Turn off power to the MultiTasker and  
disconnect AC power.  
7.1.1 RS-232 INTERFACE  
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.  
The control commands for the MT103-123 are in  
a simple ASCII character format.  
1. Square brackets “[ ]” are part of the  
command.  
Step 4. Slide the MT103-123 into the slot in order  
to connect it to the bus. Make sure the  
card fits into place. Secure the card by  
tightening the retainer screws located on  
the top and bottom of the card.  
2. Use uppercase letters for all commands.  
3. Spaces are not legal characters.  
The cards in a MultiTasker 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 from the  
card. Some commands do both simultaneously.  
Step 5. Restore power to the enclosure and verify  
the LED near the top of the card is on and  
red indicating power is applied.  
Step 6. Connect the CAT-5 cable from the video  
output of the transmitter to the RJ-45  
Input port on the MT103-123.  
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 that includes  
“ERR” plus an error code.  
Step 7. Verify the power LED at the top of the unit  
changes to GREEN, indicating a signal  
has been detected.  
Step 8. Connect the stereo audio output from the  
MT103-123 to the audio receiving device.  
Step 9. Connect the receiving monitor to the  
applicable MT103-123 video output  
connector, RGBHV/YPbPr, S-Video, or  
C-Video depending on the input type to  
the transmitter.  
Example 1: [ERR001] Error number  
Example 2: [ERRC04] Card error C4  
Step 10. Verify the picture quality on the receiving  
monitor is equivalent to the quality as  
displayed on the local monitor at the  
transmitter. If the quality of the image is  
poor or non-existent, it may be necessary  
to adjust the video equalization on the  
MT103-123 and/or the transmitter. See  
the OPERATION section that follows for  
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 MT103-123 card.  
[ Function , Card ID , Unit ID ]  
Example: [VERC3U2]  
VER = Function  
Command Format: [VERCn]  
Cn = Card ID (n = slot # from 1 to max slots)  
Example:  
C3  
U2  
= Card ID or Group ID  
= Unit ID (optional for Unit ID 0)  
An MT103-123 card is in slot 4. Send the  
command [VERC4] and 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 1-20 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.  
[MT103-123 690-0197-005 C04]  
MT103-123  
= model number  
690-0197-005 = software version  
C04  
= card ID  
2. [C]  
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.  
This command displays the status of the card.  
Command Format: [Cn]  
Cn = Card ID (n = # from 1 to max slots)  
Example:  
NOTE: In this guide, cards are referenced by  
their IDs (C1, C2...C99). Typically, the ID  
number will be equivalent to the slot number.  
Groups will be referenced by their IDs (G1-G8).  
There is one MT103-123 card in slot 4. Sending  
the command [C4] to the MultiTasker will yield  
the following feedback:  
Changing the position of a card will significantly  
affect the commands recorded on software  
definitions or third-party control systems.  
ON, EQ=0 C04  
ON  
= output is on  
= equalization is zero  
= card ID  
The unit ID has a range from U0 to U20. U0  
should be used for single unit operation. If the ID  
is set to U0, each command may be used  
without Ui. Use the command [SETU0], as  
explained in the MT101-101 User’s Guide.  
EQ=0  
C04  
If there is no card in slot 4, sending the  
command [C4] will not return any feedback.  
3. [CnS]  
Example:  
This command saves the card settings and  
displays the status. After the system is reset or  
powered off and then back on, the card restores  
the saved settings.

4. [?]  
This command displays general information  
about the MultiTasker and cards installed in the  
unit.  
The output status line always reads “ON” since  
the MT103-123 does not have an output disable  
feature.  
Command Format: [?Ui]  
Ui = Unit ID (i = from 0 to 9)  
Example:  
The software video equalization value is shown  
following the EQ prefix, or 25 out of 50.  
The input signal detect line will display a “1”  
following the SI prefix if an input signal is  
detected, otherwise a “0” will follow the prefix.  
A MultiTasker with ID 1 has a front panel with  
part number MT101-101 and contains an  
MT103-122 and an MT103-123. Send the  
command [?U1] and receive the following  
feedback:  
6. [STA1]  
This command enables automatic feedback  
from the front panel. The command affects any  
card with auto-feedback capability, not just the  
MT103-123. The default at power on or reset is  
STA0, off. For more details, see the [?Cn]

9. [EQ]  
Command Format: [EQ=mCn]  
m = Equalization (m = # from 0 to 50)  
Cn = Card ID (n = slot # from 1 to max slots)  
Example:  
This command displays the current software  
equalization setting and selects the equalization  
function for adjustment using the [+] and [-]  
commands. This command has no effect if the  
equalization switch is set for hardware control.  
Command Format: [EQCn]  
Set the equalization level of the MT103-123 card  
in slot 4 to a value of 25 by sending the  
command [EQ=25C4]. The [+] and [-]  
commands may be used to fine-tune the  
equalization at this time.  
Cn = Card ID (n = slot # from 1 to max slots)  
Example: DISPLAY EQUALIZATION  
An MT103-123 card is in slot 4 and its  
equalization level is set to zero. Send the  
command [EQC4] and receive the following  
feedback:  
13. [CLR]  
This command clears the card settings and sets  
the software equalization to zero.

14. […S] – Save  
ID COMMANDS  
This command will save the configuration  
command being sent in memory. When sending  
the command [EQ=10C4S], after reset or  
power-up, the equalization level on C4 will be  
set to 10.  
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.  
15. [TEST]  
This command performs a series of tests on the  
internal memory. The system will display the  
results and report any failures. If there are no  
problems, the system will display the following:  
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.  
MEMORY IS GOOD  
Command Format: [TESTCn]  
Cn = Card ID (n = slot # from 1 to max slots)  
Example:  
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.  
Test the internal memory of the MT103-123 in  
slot 4 by sending the command [TESTC4].  
16. [FBD]  
This command turns feedback delay on or off  
and 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.  
17. [RSI]  
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.  
Command Format: [FBDmCn]  
m = Delay (0= no delay, 1= delay 100mS)  
Cn = Card ID (n = # from 1 to max slots)  
Example:  
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

This command sets all the cards installed in the  
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.  
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.  
Command Format: [SIDn]  
Connect the computer to the second unit only  
and send the command [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.  
n
= Card ID (n = # from 1 to 99)  
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.  
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.  
19. [SIDnCi]  
21. [RSN]  
This command sets the card ID of a single card  
to a number from 1 to 99.  
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.  
Command Format: [SIDnCi]  
n
= Card ID (n = # from 1 to 99)  
Command Format: [RSNCi]  
Ci = Card ID (i = # from 1 to 99)  
Example:  
Ci = Slot Number (i = # from 1 to max slots)  
Example:  
Send the command [SID50C10] to set the ID of  
the card in slot 10 to an ID of 50.  
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:  
20. [SID+]  
This command sets the card ID of all the cards  
in a system to their slot number plus the offset  
value.  
Command Format: [SID+n]  
[4]  
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. [HELP]  
This command displays information available for  
the MultiTasker interface commands.  
Command Format: [HELPCn]

The system will return the following feedback:  
This command adds cards to a group. In  
MultiTasker systems with audio and video cards,  
the groups are typically as follows:  
[G5=0]  
Example 2:  
Group 1 = Video Cards  
Remove all cards from all groups, effectively  
deleting all groups, by sending [RMG*]. The  
system will return the following feedback:  
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 ID (k = # from 1-8)  
Example:  
Add C2, C4, and C6 to G5 by sending the  
command [WRC2C4C6G5]. After executing this  
command, G5 will consist of C2, C4, and C6.  
Now add C8 to G5 by sending [WRC8G5]. C8 is  
added to G5, and G5 is not overwritten. View  
the contents of G5 by sending [RDG5] and  
receiving the following feedback:  
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=C2C4C6]  
[G5=C2C4C6C8]  
The feedback shows G5 and then the cards that  
make up G5. In this case, G5 includes C2, C4,  
and C6.
