[CA] [CA11] AIS 500 Stuck in Silent Mode

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Marc,

The AIS500 is not stuck in silent mode ... it is simply unable to acquire a GPS position FIX. This is indicated by the amber color of the AIS500's Status LED. Should the AIS500's passive GPS antenna be mounted in a location affording it an unobstructed view of the skies overhead and should the AIS500's Status LED remain amber, then it would indicate a fault within the AIS500's internal GPS receiver circuitry or within the passive GPS antenna (and/or the GPS antenna's cable assembly). This problem would typically be fault isolated by connecting the AIS500 to a compatible passive GPS antenna (i.e. R62241 GNSS passive antenna with 10m (32.8ft) coaxial cable) which was known to be operational. Unfortunately, should the problem be fault isolated to the AIS500's GPS internal receiver circuitry, then it would unfortunately be necessary to replace the AIS500 (an AIS700 would be recommended) as Raymarine can no longer service this AIS receiver.
