I have 4 right now. If they are *true* NMEA listeners with opto-isolators on the input they should be basically no load at all. Not all mine are, so I had issues with one GPS not being able to drive them all. The GPS 17 from Garmin has no problem with them :)

Getting GPS data from the RL80CRC shouldn't be an issue at 4800 baud; but the AIS info from the radio WILL NOT be recognized by the RL80CRC; I'm not sure you can even set the ports on that unit to 38,400 baud.

If memory serves, the standard is 4800 8N1 no flow control. Remember - only ONE talker on the line and as many listeners as you want.
