How do I determine the AIS serial port?

Posted November 27, 2017

The RS-232 serial interface port for AIS can be found on the Rear Panel of the PCRP. Newer PCRPs contain a motherboard with two serial interface ports (stacked vertically). Earlier PCRPs have a single serial interface on the motherboard.

If your PCRP has two vertically stacked serial ports on the Rear Panel of the PCRP then the top serial port maps to “ttyS0” and the bottom port maps to “ttyS1”. If your PCRP only has one serial port on the Rear Panel then this port maps to “ttyS0”.

If you are using the SSRENG-7404 Four Port NMEA Serial Interface Card then the following mapping applies:

Port 1: ttyS10
Port 2: ttyS11
Port 3: ttyS12
Port 4: ttyS13
