INSTALLING YOUR MULTI-TASKER™ 6
Step 1. Slide the MT104-107 into an available
slot in the Multi-Tasker™ Enclosure in
order to connect to the bus. Make sure
that the MT104-107 card fits into place.
Secure the card to the Multi-Tasker™ by
tightening the retainer screws located on
the top and bottom of the MT104-107
card.
Step 2. The LED on the card panel will turn red
indicating that the card is in full operation.
Step 3. Connect a coaxial cable from the video
source to the input connector of the
MT104-107. Connect the output
connectors of the MT104-107 to the
display devices through a coaxial cable.
Step 4. Starting from the left, identify the slot
number where the MT104-107 card is
plugged into the Enclosure and note that
it is for RS-232 control.
OPERATION 7
7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT104-107 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.
7.1.1 RS-232 INTERFACE
The RS-232 commands for the MT104-107 are
in a simple ASCII character format.
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
Each command consists of three parts:
Function, card ID, and unit ID. [Function,
Card ID, Unit ID]
Example:
[VERC3U2]
VER = Function
C3 = Card ID
U2 = Unit ID
For Function, see a detailed explanation under
each command description.
The Card ID is an assigned value from 1 to 19
(1 to 8 or 1 to 4 depending on which enclosure
is being used), which represents the number of
slots. Card ID 0 (C0) is used for the controller
(see user’s guide for the MT100-100).
Changing the position of a card will significantly
affect the commands recorded in software
definitions or a third party control system.
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 0, then each command can be
used without Ui (use command [SETU0]; see
user’s guide for the MT100-100).
Example:
[VERC3]: for unit ID zero
[VERC3Ui]: for unit ID other than zero
[VERC3]: equivalent to [VERC3U0]
1. [VER]
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
After processing a command, an OK or ER will
be returned as feedback if "F" is included at the
end of a command string.
Commands such as [ON], [OFF], and [ IO] that
end in "S" will be saved into memory.
This command receives the software version
and card type for the MT104-107 card.
Command Format: [VERCnUi]
Cn = card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
An MT104-107 card is in slot #2 of unit 3.
Retrieve the card type and version by sending
7
Page 9
MULTI-TASKER
the command [VERC2U3]. The Multi-Tasker™
will return the following feedback:
MT104-107 690-0160-002
MT104-107 = card type
690-0160-002 = software version
2. [C]
This command receives the status of the card.
Command Format: [CnUi]
Cn = card ID (n = 1 to max slots)
Ui = unit id (i = from 0 to 9)
Example:
There is an MT104-107 card is in slot #2 of
unit 3. S-Video Input 1 is ON and C-Video
Input 3 is ON. To get the status of the card,
send the command [C2U3]. The feedback will
be as follows:
ON: 1-SVID 3-CVID
1-SVID = S-Video Input 1 ON
3-CVID = Composite Video Input 3 ON
If there is no card in slot #2 of unit 3, sending
the [C2U3] command will not return any
feedback.
3. [CnS]
This command saves the current status of the
card's input to output configuration. This
configuration will be restored after the system is
Reset or powered OFF then ON.
Cn = card number
S = save configuration
If S-Video Outputs 1,2,3 and Video Outputs
1,2,3 are enabled, the feedback after sending
the command [C4S], for slot 4, would be:
SVID: 1,2,3 CVID: 1,2,3 C04 Saved
4. [ON]
This command enables one input of a single
card or a group of cards.

TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MT104-107; however, we
would like to offer suggestions for the following:
8.1 LED IS NOT LIT
Cause 1 Card cage is not plugged in.
Solution: Plug card cage in. If the LED lights,
the problem is solved. If the LED is
still not ON, see Cause 2.
Cause 2: Card is not plugged in all the way.
Solution: Push the card in all the way. If the
LED is still not ON, see Cause 3.
Cause 3: Card cage slot has a problem.
Solution 1 Test the card in other slots of the
card cage. If the slot was damaged,
the card may work in other slots. If
other slots work and the LED lights,
the problem is the card cage slot.
The card cage may require service.
Call ALTINEX at (714) 990-2300. If
the other slots do not work and the
LED is still not lit, see Solution 2.
Solution 2 Take any other known good card
with an LED and install it in the
questionable slot. If the LED on the
good card comes ON, then the
original card may be the source of
the problem. Call ALTINEX at
(714) 990-2300.
8.2 NO DISPLAY
Cause 1 The source has a problem.
Solution: Check the source and make sure
that there is a signal present and all
source connections are correct. If
the source is working and there is
still no display, see Cause 2.
Cause 2: The card input is not selected.
Solution: Select the card input. See RS- 232
accessible commands in section 7.
If no display is present, see
Cause 3.
Cause 3: Cable connections to the
destination are incorrect.
Solution: Make sure that cables are
connected properly. Also, make
sure that the continuity and wiring
are good. If there is still no display
present, see Cause 4.
Cause 4: The display has a problem.
Solution: Make sure that the display is
powered. If there is still no display,
call ALTINEX at (714) 990-2300.
