[CA] AIS Transmitter for My E-120 System

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tfvassallo,

The AIS250 would need to be replaced with an AIS650. As the AIS650 is a Class B AIS transceiver, it must be interfaced to the passive GPS antenna which is packaged with the AIS650. This passive GPS antenna will need to be installed in a location affording it an unobstructed view of the skies overhead. The AIS650 will need to be interfaced to a dedicated VHF antenna having a gain of no more than -3dB. Alternatively, the AIS650 may be interface to an AIS100 Class B AIS Antenna Splitter, which would permit a single VHF antenna to support the VHF radio and AIS650. Like the AIS250, the MFD's NMEA 0183 cable will be interfaced to the 38400 BAUD NMEA 0183 leads of the AIS650. Should a DSC VHF radio's NMEA 0183 input leads presently be interfaced to your AIS250's 4800 BAUD NMEA 0183 terminals, then these NMEA 0183 leads will instead be interfaced to the 4800 BAUD NMEA 0183 output leads of the AIS650. The AIS650's power, ground, and drain leads will be spliced to the power, ground, and drain leads currently in place for the AIS250.
