B.16.4 Error Messages Associated with the Flash
RAM
1. Several error messages may occur during programming. All of them allow the user to
restart the programming process. If multiple failures occur, the serial cable connection may
be intermittent or there may be excessive noise on the serial line. Take steps to assure a
solid connection between the PC and CHPA. Use a shielded cable where the shield attaches
to the connector shell. Use a short cable - don't exceed 20ft. The error messages you may
see include:

Incorrect message length error means that the CHPA hasn't received all of the characters that it
expected to receive. This error will appear if the serial cable is removed during Flash RAM
programming.
