1NMEAto4 – NMEA Expander 4-Channel

The 1NMEAto4 is used for the distribution of data from one serial source (NMEA or RS232) to max. 4 receivers (RS422 or NMEA). By using NMEA as a serial source, the RS232 interface can be used for the monitoring of the data streams. The four outputs of the module are individually selectable by switches to RS422 or NMEA.

The NMEA input is galvanically isolated from the RS232 interface, the 4 outputs, and the power supply.
