1NMEAto4RG – NMEA Expander 4-Channel
The module 1NMEAto4RG is used to distribute data from two alternative NMEA sources to 4 parallel working NMEA transmitters (CH3 to CH6).
The module 1NMEAto4RG is used to distribute data from two alternative NMEA sources to 4 parallel working NMEA transmitters (CH3 to CH6). Through a redundancy circuit, CH1 is switched over to CH2 after about 4 seconds in the absence of input data.
At the same time, an error message signaled through a red LED and the alarm relay is opened. The inputs and the outputs are galvanically isolated from each other and the power supply.
