The GIA 63W contains a total of 5 channels of RS-485 serial data communications. Two of these
channels can also be configured as RS-422 mode channels to allow for system flexibility. These data
busses conform to EIA standard RS-485, or RS-422, depending on which mode they are currently
operating in.
