ABOUT YOUR MT107-202 2
MT107-202
8 BALANCED AUDIO INPUTS
The MT107-202 is an 8 Balanced Audio Input
expansion card for use with the MT107-103 64X64
Matrix Engine. The MT107-202 is capable of
receiving balanced audio signals.
Each MT107-202 connects to the Input Connector
on the MT107-103 Matrix Engine. Up to 7
expansion cards may be connected to the Engine.
Each card is connected to the Engine via special
cables provided with the Engine.
Audio Input signals are buffered to the matrix
system through individual Differential Line
Receivers. In many audio/visual environments,
there may be a great deal of noise and other
interference from power lines, electronic equipment
and poorly shielded cables. The MT107-202 utilizes
balanced audio inputs in order most effectively
reduce and/or eliminate "hum" and other forms of
noise.
Volume control, including mute capability, is
employed on the MT107-202. The volume and
mute controls may be applied to any individual
input and are software controlled for flexibility.
As part of the MT107-103 Matrix Engine, the
MT107-202 has built-in special features. Signal
detection circuitry allows the user to determine the
presence of an input signal on any channel.
Altinex's software and hardware allow for the
switching of any input to output combination and
prevents illegal switching combinations that may
damage components.

INSTALLING YOUR MT107-202 6
Step 1. Locate the MT107-103 currently installed
in the Multi-Tasker™. Ensure there are
enough empty slots in the enclosure to
allow for the one or more MT107-202's to
be installed.
Step 2. Route the ribbon cables through the notch
in the add-on boards and connect to the
MT107-103 base assembly using special
cables provided with the Engine. Make
sure that cable connector is secured in
the socket of the input card.
Step 3. Carefully, slide the MT107-202 into an
empty slot in the Multi-Tasker™
Enclosure.
Step 4. Secure each card by tightening the
retainer screws at the top and bottom of
each card.
OPERATION 7
7.1 RS-232 CONTROL
The MT107-202 has many advanced remote
control capabilities when used in the
Multi-Tasker™ Enclosure as part of an
MT107-103 Matrix Switcher. These capabilities
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
Please, see the MT107-103 User's Guide for a
full listing of commands available for the
MT107-202 as part of a Multi-Tasker™ Matrix
Switcher.
TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MT107-202. However, we
would like to offer suggestions for the following:
8.1 NO SOUND
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 sound, see Cause 2.
Cause 2: The input signal is not detected.
Solution 1: In MTSetup™, or other control
software, send the [SDI] command.
This command is detailed in the
MT107-103's User Guide. Verify a
signal is detected for the input
number in question. If a signal is not
detected, see Solution 2.
Solution 2: Verify the MT107-202 is connected
to the MT107-103 and that the cable
is in good condition. If a signal is
detected, see Cause 3. If there is no
signal detected, please, call Altinex
at [phone].
Cause 3: The path is not selected.
Solution: Make sure the input to output path is
correctly selected.
For example, Input 17 is connected
to Output 1 in the matrix engine.
Physically, the source signal is
connected to Input 17 and the
receiving device cable is connected
to Output 1. See RS-232 accessible
commands in Section 7 of the
MT107-103's User Guide for
command details.
If no sound is present, see Cause 4.

MULTI-TASKER™

Cause 4: Input volume is too low or muted.
Solution: Check the volume for the selected
input to output connection. Turn
OFF the MUTE function and try
adjusting the volume. If there is still
no sound, see Cause 5.
Cause 5: Cable connections are incorrect.
Solution: Make sure that cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no sound present, see
Cause 5.
Cause 6: The receiving device has a
problem.
Solution: Make sure the receiving device has
power and is turned ON. If there is
still no sound, please call Altinex at
[phone].
