4.5 EP and COM2 Faults
NO COM2. TRY RESTART
(System Messages from M3 via COM2 are Missing)
NOT RECORDING
(M3 Program or Windows has Halted not Running)
This indicates that there is a loss of communication between the M3 Software /PC
and the CDP/MEU. The restart is due to data from COM2 timing out.
Check the saved data leading up to the restart. The $PAMIV messages from the CDP
should reveal what was going on.
If the M3 software suddenly stops then after a while you should see the restart
messages appear on the CDP
The CDP will only restart the motherboard after M3 software fails, or after a power
restart.
Test Equipment:
- SVGA Monitor
- Keyboard and Mouse
- On CDP switch 4-5 (Auto Restart Disabled) is on.
Test Cables:
NONE
Fault Correction:
Check ‘Output from EP COM2 LED’.
On maximising the M3 program access the ‘Config’ and ensure that both COM1 and
COM2 have 38400 selected.
