data multiplexer-converter / NMEA / NMEA / for ships
The alarm converter is used to connect nautical instruments with NMEA Alarm outputs to the bridge alarm systems. According to the Standard IEC61162-1, the alarm telegram switching information for a relay contact can be processed which are derived from the bridge alarm system. From the corresponding switching output of the alarm system for ACK or mute, a NMEA telegram $ ssACK, xxx * hh will be formed which will send to the nautical system. There are two digital channels available, each with an input and relay output (NO) and a serial channel. The functionality of the VL-ALR-CH is configurable via parameters.
