OPERATION
7.1 RS-232 CONTROL

INSTALLING YOUR MT113-102/103
6
Step 1. Slide the MT113-102/103 into an available
slot in the Multi-Tasker™ Basic Enclosure
in order to connect to the bus. Make sure
that the MT113-102/103 card fits into
place. Secure the card to the Multi-
Tasker™ by tightening the retainer
screws located on the top and bottom of
the MT113-102/103 card.
When used in the Multi-Tasker™ Enclosure, the
MT113-102/103 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.
Step 2. The LED on the card panel will turn red
indicating that the card is in full operation.
7.1.1 RS-232 INTERFACE
Step 3. Connect audio cables from the audio
source to the input connector of the
MT113-102/103. Connect the output
connectors of the MT113-102/103 to the
audio equipment through an audio cable.
The RS-232 commands for the MT113-102/103 are
in a simple ASCII character format.
1.
Square brackets “[ ]” are part of the
command.
2.
3.
Use uppercase letters for all commands.
Commands may be executed with or
without a space.
Step 4. Starting from the left, identify the slot
number where the MT113-102/103 card is
plugged into the Enclosure and note that
it is for RS-232 control.
After processing a command, an OK or ER will be
returned as feedback if "F" is included at the end of
a command string or if the unit ID is zero.

Ui = unit id (i = from 0 to 9) (refer to the MT100-
100 user’s guide for explanation)
7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts: function,
card ID, and unit ID. [Function, Card ID, Unit ID]
Example:
If one MT109-102 card is in slot #2 of unit 3 with
input 1 ON:
Example:
To send command [C2U3], the Multi-Tasker™
Enclosure will return feedback information about
card status, which will display all current
settings:
VOLIN1:16
VOLIN2:16
VOLIN3:32
VOLOUT:12
BASS:8
TREBLE:14
LOUDNESS:ON
If there is no card in slot #2 of unit 3, sending
the [C2U3] command will not return any
feedback.
[VERC3U2]
VER = Function
C3 = Card ID
U2 = Unit ID
For detailed information regarding function, see
each command description.
Card ID is an assigned value from 1 to 19, 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 on
software definitions or a third party control system.
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).
3. [CnS]
This command is to save card status such as
ON/OFF, IN/OUT, and volume control where
applicable.
Example:
4. [SELmCnUi]
[VERC3]: for unit ID zero
[VERC3Ui]: for unit ID other than zero
[VERC3]: equivalent to [VERC3U0]

[SELmCnUi] [–] [–] [–] [–] or [+] [+] [+] [+]
m = Input number (m = 1 to 3)
n = Card ID number (n = slot # from 1 to 19)
i = Unit ID number (i = 0 to 9)
+ = increases volume. (maximum of 15 levels
for audio).
– = decreases volume. (maximum of 15 levels
for audio).
1. [VERCnUi]
This command receives the software version
and card type for the MT113-102/103 card.
Cn = card ID number (n = # from 1 to 19)
Ui = Unit ID (i = # from 0 to 9) (refer to the
MT100-100 user’s guide for explanation)
Example:
Example:
If one MT113-102 card is in slot #2.
To send command [VERC2], the Multi-Tasker™
Enclosure will return:

TROUBLESHOOTING GUIDE
8
We have carefully tested and have found no
problems in the supplied MT113-102/103; however,
we would like to offer suggestions for the following:
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 sound present, see Cause 4.
8.1 LED IS NOT ON
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 lights, see Cause 2.
Cause 4: The destination amplifier has a problem.
Solution 1: Make sure that the destination amplifier
is powered. If there is still no sound, see
Solution 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 lit, see Cause 3.
Solution 2: Set the volume of the destination
amplifier to a reasonable level. If there
is still no sound, call ALTINEX at (714)
990-2300.
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.
8.3 SOUND DISTORTION
Cause 1: The source level is above 1Vp-p.
Solution1: Make sure that the source level is
below 1V p-p. If the sound is still
distorted, see Solution 2.
Solution 2: Call ALTINEX at (714) 990-2300.
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.
8.4 SOUND LEVEL IS LOW
Cause 1: The volume levels are inappropriate.
Solution 1: Turn up the source volume. If sound
level is still low, see Solution 2.
Solution 2: Turn up the destination amplifier
volume. If the sound level is still low,
see Cause 2.
8.2 NO SOUND
Cause 1: The source has a problem.
Cause 2: Poor signal transmission.
Solution Check the source and make sure that it
is working at an appropriate volume
level and all source connections are
correct. If the source is working and
there is still no sound, see Cause 2.
Solution: Check the cables for continuity and
make sure that connections are wired
properly to verify that there is good
signal transmission. Note: Test the
system by removing the card from
between the source and the destination
amplifier. If problem persists, call
ALTINEX at (714) 990-2300.
Cause 2: The proper card input may not be
selected.
Solution: Select the card input that is used, by
RS-232 accessible commands in
