[CA] [CA11] SPLITTER FOR AIS - VHF Active or Passive?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Alterboy,

Please note that when a VHF antenna is shared between an AIS350/650 and a VHF radio, a Class B AIS Antenna Splitter must be installed. Failure to do so may result in damage to the receiver section of the AIS350/650 and/or VHF radio. While Raymarine no longer offers a Class B AIS Antenna Splitter because the AIS700 features a built in antenna splitter, third party Class B AIS antenna splitters (ex. Digital Yacht SPL2000, etc.) are available in the market.

Please additionally note that installation of a Class B AIS Antenna Splitter would have no effect upon Silent Mode state of an AIS650. Should an AIS650 remain in silent mode:

- verify that the AIS650 has been updated with the latest available Raymarine product software update.

- verify that the AIS650 has not simultaneously been interfaced to the system via its NMEA 0183 and SeaTalkng communications interfaces.

- verify that the AIS650's Silent Mode leads do not create a closed circuit. Any exposed conductors of these leads should be clipped off and the leads should then be insulated to prevent shorting.
