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
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. DISTORTED SOUND
Cause 1: The source level is above 1Vp-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: Volume levels are inappropriate.
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.
Cause 2 Poor signal transmission.
Solution: Check the cables for continuity and
make sure that connections are
wired properly to verify that there is
good signal transmission.
NOTE: Test the system by removing
the MT110-101/103 card
from between the source and
the destination amplifier. If
the problem persists, call
ALTINEX at (714) 990-2300.
