NN3D BB data2 port

The Data2 port on BB, TD2 and TD3, is that RS232 or RS422 level? thanks

NMEA.ORG requires that all certified NMEA 0183 is at RS422 levels. The NN3D NMEA ports are certified and at these RS422 signal levels.

Thanks.. I remember seeing 4800baud in the setup but not sure of how many data bits, start, stop and parity bits. Thanks
