The protocol is a custom one developed in-house. All the hardware
requirements needed custom designs, so there was no requirement
to support DeviceNET or CANOpen devices.

I think it would have been nice to use a standard protocol, but
I have not investigated the original arguments for not using
a standard protocol. Perhaps there were some specific requirements
that were more easily met (eg. required less microcontroller
processing) to support. I believe the protocol developed made
extensive use of the hardware support in the XAC3's for
message filtering, to reduce their message processing.
