Transmission mode

Switches between Single-ended and Differential transmission modes.

The Differential transmission mode supports higher speeds, longer cable runs, and better data integrity. Differential mode works when connected to opto-isolated inputs, as specified by the NMEA 0183 standard.

The Single-ended mode is required when sending a signal to a single-ended receiver device, such as a PC for example.

Refer to the NMEA 0400 Installation Standard for wiring guidelines for the different transmission modes.
