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
