We have carefully tested and have found no
problems in the supplied MT103-104/(109)(110) ;
however, we would like to offer suggestions for the
following:
8.1 LED IS NOT LIT
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 there is still an
Solution 3: Call ALTINEX at (714) 990-2300.
Cause 2: The MT103-104/(109)(110) 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
Solution 3.
Solution 2: Call ALTINEX at (714) 990-2300.
Cause 3: RS485 communication error
Solution 1: Make sure that the card is pushed
all the way into the slot.
Solution 2: Turn the system OFF and then ON
again. If there is still an error, see
Solution 3.
Solution 3: If there is still a problem, call
ALTINEX at (714) 990-2300.
Cause 4: 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.
