Network connections ContentsData connections overviewThe AIS unit includes 2 bidirectional NMEA 0183 connections, as well as NMEA 2000 / SeaTalkng, and USB connections. The AIS unit can multiplex the data received on its NMEA 0183 inputs with its AIS data, and then output this combined data to an external NMEA 0183 device, via the AIS unit’s high speed (38,400) NMEA 0183 output.USB connectionBefore using your product for the first time, you must configure it using the proAIS2 software, via a PC connected to the USB connection. NMEA 2000 / SeaTalkng connectionYour product can transmit data to devices connected on SeaTalkng® or NMEA 2000 CAN bus networks. Connection is established using the DeviceNet connector located on the bottom of the unit.NMEA 0183 connectionThe AIS700 can transmit and receive NMEA 0183 data, using the NMEA 0183 wires located on the power / data cable.GPS (GNSS) antenna connectionConnect the supplied GNSS antenna to your AIS700 using the GNSS antenna connection. The antenna is fitted with a 10 m (33ft) cable for connecting to the AIS700.VHF antenna connectionConnect a VHF antenna (not supplied) to your AIS700 using the VHF antenna connection. VHF radio connectionFor systems that include a VHF DSC radio, you can share the VHF antenna by connecting your Radio’s VHF antenna connection to the VHF Radio connection on your AIS700. Connect your VHF antenna to the AIS700’s VHF antenna connection.Silent mode switch connectionIn Silent mode your AIS700 will stop transmitting position data and operate as a receiver only. Silent mode can be enabled using a connected MFD and by connecting a switch to the relevant wires on the Power/data cable. Please refer to your MFD’s operation instructions for details on enabling silent mode.Previous topic: MountingNext topic: Power connections
