TROUBLESHOOTING GUIDE

8

We have carefully tested and have found no
problems in the supplied 

MT105-120/121

;

however, we would like to offer suggestions for the
following:

8.1  CARD IS NOT RECOGNIZED

Cause 1:

The card is not recognized.

Solution:

Reset the card cage by sending the
[RES] command, or turning the
system power off and then on. Send
the [C] command to see if there is
communication with the card. If
there is no feedback, see Cause 2.

Cause 2:

Card is not plugged in all the way.

Solution:

Push the card in all the way. Reset
the system and send the [C]
command. If the card is still not
recognized, 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 card is
recognized, 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, see Solution 2.

Solution 2:

Take any other known good card
and verify that the slot used is good
by seeing if the other car is
recognized in that slot. If it is, then
the original card may be the source
of the problem. Call ALTINEX at
(714) 990-2300.

8.2  NO DISPLAY

Cause 1:

The source has a problem.

Solution:

Check the source and make sure
that there is a signal present and all
source connections are correct. If
the source is working and there is
still no display, see Cause 2.

Cause 2:

The card output is not selected.

Solution:

Select the output. Accessible
commands in are in Section 7. If no
display is present, see Cause 3.

Cause 3:

Cable connections are incorrect.

Solution:

Make sure that cables are properly
connected and that the continuity
and wiring are good. If there is still
no display present, see Cause 4.

Cause 4:

The display has a problem.

Solution:

Make sure the display has power
and is turned ON.  If there is still no
display, please call Altinex at
(714) 990-2300.
