The MT109-100 is primarily designed to utilize the
inputs and output offered on the connector panel.
However, it also offers a "hidden" feature that
enables access to the MultiTasker signal bus. The
signal bus spans the width of the MultiTasker
Basic Enclosure along the back plane of the unit.
Through RS-232 control, the MT109-100 can send
or receive stereo audio signals to or from this bus,
from any of the applicable cards in the enclosure.

This feature can be used in a variety of ways to
expand the capabilities of the card. For example,
two MT109-100 cards can be installed in the
MultiTasker and the output of one can be routed to
an input of the other, creating a 15-input 1-output
switcher. Note that the signal bus handles only one
stereo audio signal path at a time.

DIAGRAM 3: JUMPER SETTINGS
The MT109-100 has 8 external inputs with 1 internal input and 1 output. The internal input is from the
Expansion card through a 10-pin ribbon cable, which is connected between P12 of the Expansion card
and P12 of the Master card. The 4 external inputs are configured as inputs 1 thru 8.
The 1 internal input is configured as input 7 or input 8. Only one of two internal inputs is used at a time
and it depends on how the jumpers on the Expansion are set.
Setting Jumpers:
1) As an Expansion card: set P13 as port 7 (L1E and R1E) or port 8 (L2E and R2E)
2) As a Master card: set jumpers on P23 and P24 as described below.
If the Expansion card's jumpers on P13 are set on L1E and R1E, the Master card must select internal
input 7 on P23 (L1E) and P24 (R1E).
If the Expansion card's jumpers on P13 are set on L2E and R2E, the Master card must select internal
input 8 on P23 (L2E) and P24 (R2E).
Note: The MT109-100 configuration is 8-in, 1-out stereo audio switcher. For a 15-in, 1-out switcher
configuration, use two MT109-100 cards. One as a Master card and the other as an Expansion
card. (See page 9.)

INSTALLING YOUR MT109-100
Step 3. The LED on the card panel will turn red
indicating that the card is in full operation.
A green LED indicates that a signal is
present. An LED that is blinking red
indicates that the card is experiencing a
problem. If the LED is blinking, see
Troubleshooting Guide in section 8.

Step 1. Determine how the MT109-100 is going
to be configured.
The MT109-100 is configured as an 8-in
1-out Stereo Audio Switcher. It may be
configured as a system with 15-in, 1-out
using two MT109-100 cards. One card is
configured as a Master card and the
other is configured as an Expansion card.
Step 4. Connect audio cables from the audio
source to the input connector of the
MT109-100.
Connect
the
output
connectors of the MT109-100 to the
audio equipment through an audio cable.
In Application Diagram, DIAGRAM 4, on
page 8, the Master card is set to accept 7
external inputs, 1 internal input and 1
output.
The Expansion card has 8
external inputs (inputs 8 thru15). For
RS-232 commands, the 8 external inputs
of the Expansion card must still be
configured as inputs 1 thru 8.
Step 5. Starting from the left, identif y the slot
number where the MT109-100 card is
plugged into the Enclosure and note that
it is for RS-232 control.
OPERATION
For example, if the master card is at slot
1 and the Expansion card is at slot 2, to
select inputs 1 thru 4, use the following
commands to select different inputs:

7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT109-100 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.

7.2 DESCRIPTION OF COMMANDS
Each command consists of three
Function, Card ID, and Unit ID.
[ Function , Card ID , Unit ID ]
Send the command [VERC2] to check the
version of the MT109-100 in slot 2. The system
will return the following feedback:
parts:
MT109-100 690-0179-003
Example: [VERC3U2]
MT109-100 = card type
690-0179-003 = software version
VER = Function
C3 = Card ID
U2 = Unit ID
2. [C]
For Function, see a detailed explanation under
each command description.
This command receives the status of the card.
Command Format: [CnUi]
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,
1 to 8, or 1 to 19 depending on the enclosure.
Cn = card ID (n = # from 1 to max slots)
Ui = unit id (i = 0 to 9)
Example:
An MT109-100 card is in slot #4. Sending the
command [C4] to the Multi-Tasker™ will yield
feedback similar to the following:
Card ID 0 (C0) is used for the controller. See
the MT100-100 User’s Guide for details.

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.

8.2 LED IS BLINKING RED
Cause 3: Cable
connections
to
destination are incorrect.
Cause 1: The CPU on the card is not
working properly.
Solution:
Solution 1: Look at the card and verify that
there is no damage. If there is no
damage, see Solution 2.
the
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.
Solution 2: Verify that all IC’s are seated in their
sockets. If the LED is still blinking
red, see Cause 2.
Cause 4: The destination amplifier has a
problem.
Cause 2: The card and its serial device are
not communicating.
Solution 1: Make sure that the destination
amplifier is powered. If there is still
no sound, see Solution 2
Solution:
Turn the system OFF and then ON
again. If there is still an error, see
Cause 3.
Solution 2: Set the volume of the destination
amplifier to a reasonable level. If
there is still no sound, call ALTINEX

Cause 1: The source level is above 1V p-p.
Solution:
Solution 2: Turn the system OFF and then ON
again. If there is still an error, see
Solution 3.
Cause 2: The destination amplifier provides
excessive amplification.
Solution 3: Call ALTINEX at (714) 990-2300.
8.3 NO SOUND
Solution 1: Make sure that the source signal
level is high enough so that the
destination amplifier does not have
to provide excessive amplification
and thereby distort the signal. If
there is still sound distortion, see
Solution 2.
Cause 1: The source has a problem.
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 2: Call ALTINEX at (714) 990-2300.
Cause 2: The proper card input may not be
selected.
Solution:
Make sure that the source level is
below 1V p-p. If the sound is still
distorted, see Cause 2.
8.5 SOUND LEVEL IS LOW
Cause 1
