This parameter will increment every time a CTSync message is received with a bad
checksum
This parameter will increment every time a message has not been received when the
module is expecting one.
This parameter will increment every time the synchronization signal is the incorrect
width. During synchronization this parameter is likely to increase but should stabilise
once synchronization is complete. After synchronization, if this parameter is
incrementing then there is likely to be excessive noise on the EIA-RS485 network.
Check the connections.
This parameter allows the user to set up the Second Processor in the Inter-Option
module Synchronization scheme. For more information refer to Chapter 10 Inter-option
Synchronization on page 104.
