TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MT110-100/102; 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 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.
8.2 LED IS BLINKING RED
Cause 1: The CPU on the card is not
working properly.
Solution 1: Look at the card and verify that
there is no damage. If there is no
damage, see Solution 2.
Solution 2: Verify that all ICs are seated in their
sockets. If the LED is still blinking
red, see Cause 2.
Cause 2: The card and its serial device are
not communicating.
Solution 1: Turn the system off and then on
again. If there is still an error, see
Cause 3.
Cause 3: RS485 communication error
Solution 1: Make sure that the card is pushed
all the way into the slot. If there is
still an error, see Solution 2.
Solution 2: Turn the system off and then on
again. If there is still an error, see
Solution 3.
Solution 3: Call ALTINEX at (714) 990-2300.
8.3. NO SOUND
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.
Cause 2: The proper input card may not be
selected.
Solution: Select the card input that is used, by
RS-232 accessible commands in
section 7. If no sound 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 sound
present, see Cause 4.
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
