Hi

The Navico Corus system uses the canbus protocol,

an open protocol, which is commonly used in automotive engine control
systems. This is similar to NEMA but faster. Try googling for canbus
and you may be able to find information to help you to troubleshoot.

And don't forgot to bring a good digital storage scope and a CAN bus
analyzer.....
