Simrad’s R10 Interface Junction Box provides heading input for systems with NMEA 2000 backbone (SimNet). Connects the RI10 to a SimNet or NMEA2000 network to allow heading and position information to be sent to the scanner for MARPA calculations. Main data network interface between the radar and the display (ethernet). Provides data and power connection between the Broadband radar dome and the RI10. Units green LED indicates power is supplied to the RI10 and indicates SimNet state. A sequence of three rapid flashes indicates no SimNet connection was made at time of power up and a solid light means SimNet connection was lost after power up. Note: Lowrance HDS units sold in the USA do not require an interface box and the scanner connects directly to the display or Ethernet switch. If chart overlay or MARPA are required for Lowrance HDS USA then an RI10 Interface box and heading sensor are required. Powered by 12 or 24 V DC and uses a 5-amp fuse or breaker. The RI10 receives heading via SimNet or NMEA2000 network and transmits this data to the radar, where MARPA processing is performed. For Simrad installations with more than one SimNet heading source the RI10 will use the Simrad group source. The source used by the Simrad group can be viewed or changed via an NSE / NSO / NSS display in the settings menu. Unit measures (W x D) 6.76
