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 IC’s 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:
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 card input 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
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.
8.4 SOUND DISTORTION
Cause 1:
The source level is above 1V p-p.
Solution:
Make sure that the source level is
below 1V p-p. If the sound is still
distorted, see Cause 2.
Cause 2:
The destination amplifier provides
excessive amplification.
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.
Solution 2:
Call ALTINEX at (714) 990-2300.
8.5 SOUND LEVEL IS LOW
Cause 1
Input volume is low.
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.
