[CA] [CA11] AIS 650 not transmitting reliably

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Labratdeb,

The reported issue may occur if the AIS650 has been interfaced to the system via both NMEA 0183 and SeaTalkng. Given the equipment listed, the AIS650 should only be interfaced to the system via SeaTalkng. With regard to Silent Mode, this mode may be configured via the i70S MFID or via the MFD. When the setting is changed on one of these devices, it should be repeated on each of the system's MFDs and i70/i70S MFIDs. Next, the AIS650 will not transmit (will appear silent) if it is unable to acquire a GPS position FIX or has lost the position FIX. Care should be taken to ensure that the AIS650's GPS antenna has been positioned where it will have an unobstructed view of the skies overhead. If so, and the problem persists, then the AIS650's Status LED should be examined. If it is amber, then it hasn't acquired or has lost its GPS position FIX. If it is green, then it should be transmitting (recommend checking with a nearby vessel equipped with an AIS receiver (MarineTraffic.com is not a particularly reliable tool for this purpose ... particularly in not located near a receiver). If the AIS650's status LED is green and other nearby AIS equipped vessels are unable to receive your system's transmissions, then it would be recommended that the AIS650 be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
