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.

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.

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.

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
will then be 4.
The command [HELPC10] is sent to the card in
slot 10. 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.

18. [SIDn]
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

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:
G1-G8: EMPTY
26. [RD]
This command reads and then displays the
members in a group.
Command Format: [RDGk]
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.

Cause 1: There is no power.
We have carefully tested and have found no
problems in the supplied MT103-123. However, we
would like to offer suggestions for the following:
Solution: Disconnect the video input from the
MT103-123 and verify the LED is on
and red indicating power is present.
Reconnect the computer's video
output. If the LED is still not green
see Cause 2.
8.1 LED IS NOT RED
The LED should be on and red when power is
applied and there is no video signal present. If
the LED is on and green, the unit is receiving
power and a signal.

cage slot. The card cage may
require service. Call ALTINEX at

not work and the LED is still not lit,
see Solution 2.
Cause 2: Cable connections are incorrect.

Solution 2: Take any other known good card
with an LED and verify that the slot
used is good by seeing if the other
card’s LED lights in that slot. If it
lights, then the original card may be
the source of the problem. Call
ALTINEX at (714) 990-2300.
