[CA] [CA11] E140\W chart plotter wit AIS500 and GPS not initializing

zed1776,

Q1. The MFD initializes, the Limitation of Use is displayed, as always, and I continue to the chart page which loads up no problem. The AIS is off and GPS is no signal.
A1. As indicated within my initial response, Class B AIS transceivers such as the AIS500 are not typically configured to supply GPS data to systems. The MFD should have been interfaced to an external GPS sensor (ex. Raystar 125, Raystar 130, etc.) which in turn would have supplied the system with GPS data. It typically takes the Raystar 125 GPS Sensor less than three minutes to acquire a GPS position FIX after being powered ON. Should the system have been interfaced to a Raystar 125 GPS Sensor and should the GPS be slow to acquire or loose its GPS position FIX, then Please click here to view a FAQ addressing how to proceed.

Q2. Does the AIS have its own GPS or is it using the Seatalk/GPS antenna data feed?
A2. As indicated within my initial response, the AIS500 is not dependent upon an external SeaTalk / NMEA 0183 GPS data source for its operation. Like all Class B AIS transceivers, the AIS500 features an internal GPS receiver which is reliant upon a passive GPS antenna to collect and deliver GPS signal to the AIS500. This GPS antenna is connected to the AIS500's GPS antenna socket.
