Basic Troubleshooting Checks
Failures of a general nature (affecting many cards and/or functions simultaneously), or gross
inoperability errors are best addressed first by performing basic checks before proceeding further.
Table 3.5
provides basic system checks that typically locate the source of most general problems.
If required and applicable, perform further troubleshooting in accordance with the other
troubleshooting tables in this section.
Processing Error Troubleshooting
Table 3.6
provides LDP-8242 processing troubleshooting information. If the LDP-8242 card
exhibits any of the symptoms listed in
Table 3.6
, follow the troubleshooting instructions
provided.
In the majority of cases, most errors are caused by simple errors where the LDP-8242 is not
appropriately set for the type of signal being received by the card.
The error indications shown below are typical for the corresponding error conditions listed. Other
error indications not specified here may also be displayed on DashBoard™ and/or the LDP-8242
card-edge status indicators.
Where errors are displayed on both the LDP-8242 card and network remote controls, the
respective indicators and displays are individually described in this section.

Item
Checks
Verify for power presence
On both the frame Network Controller Card and the LDP-8242, in all cases when
power is being properly supplied there is always at least one indicator illuminated.
Any card showing no illuminated indicators should be cause for concern.
Check Cable connection
secureness and connecting
points
Make certain all cable connections are fully secure (including coaxial cable attachment
to cable ferrules on BNC connectors). Also, make certain all connecting points are as
intended. Make certain the selected connecting points correlate to the intended card
inputs and/or outputs. Cabling mistakes are especially easy to make when working
with large I/O modules.
Card seating within slots
Make certain all cards are properly seated within its frame slot. (It is best to assure
proper seating by ejecting the card and reseating it again.)
Check status indicators and
displays
On both DashBoard™ and the LDP-8242 card-edge indicators, red indications signify
an error condition. If a status indicator signifies an error, proceed to the following
tables in this section for further action.
Troubleshoot by substitution
All cards within the frame can be hot-swapped, replacing a suspect card or module
with a known-good item.
