Communication card (more likely): The prefix “DMC” and the context of the GE Mark V system still indicate that communication is a common possibility. The functions of this card may be related to the following:
Manage communication interfaces (such as serial ports, Ethernet).
Specific communication protocols for handling data exchange within the system.
Variants of communication cards (possible): The suffix “AZZ03A” may indicate variants of DMCBG1A cards with specific functions. It may be:
Different communication interface versions (e.g. support for additional protocols).
Card revision, including communication related error fixes or minor feature enhancements.
