Mismatched baud rate (actually, after
initialization and “Setup Complete” the
diagnostic line would first report “Port x
ERR Coms Parity” followed by the
Framing error message.
Failure of Comms line after power up
and initialization.
Mismatched parity entry in the Comms
file.
If the communications line is faulty (mis-
wired or not seated, for example), then,
on initial power-up, the diagnostic
screen will indicate this error message.
If the communication line goes bad after
power-up and initialization, then a Port x
ERR Coms Fatal error will occur
followed by a Port x ERR Max Retry
message.
Temporary communications fault.
Noise on the data line.
Port x ERR Coms Framing
Port x ERR Coms Fatal
Port x ERR Coms Parity
Port x ERR Coms Max Retry
Symptom Possible Cause Corrective Action
Correct the Comms file baud rate
settings to match those of the equipment
it is attached to.
Check and correct hardware fault.
Correct the Comms/configuration file for
correct settings.
Check and correct the hardware fault.
Fault will automatically be corrected
when communications resume.
Check data cables.

CC1 System Errors
8.0 TROUBLESHOOTING/COMMON PROBLEMS
In the tables below, some of the more common problems associated with CC1 power up,
initialization, and operation are shown. For many of these, we also list possible causes
and solutions.
Problems with the CC1 may occur in the following areas:
• The CC1 itself.
• Setup files (also known as configuration files or flat files).
• Peripheral Devices connected to the CC1.
• The DOS operating system.
It is important that a log be kept of all changes made to the system whether they be hard-
ware or software related. The commentary should document the change made, why it was
made, the date it was made, and the person responsible for the change. That way it will be
easier to backtrack if errors occur. It also makes it easier to separate errors caused by the
last recorded change from other types of errors, whenever one occurs.
Table B lists some common CC1 equipment errors.
Table C lists some common CC1 initialization problems.
