[TG] [TG11] AIS 650 stops displaying targets

[Tom - Raymarine - Moderator]

Hello Tim,

Some questions:

• Does the AIS appear in the eS127's SeatalkNG device list (Home > Setup > Maintenance > Diagnostics > Select Device), at the time the problem is happening?
• What does the AIS's LED show, at the time the problem occurs?
• Does the AIS work with the PC over USB the rest of the time?
• If you disconnect the STNG, does the NMEA0183 work?
  

The AIS is designed to be connected over either SeatalkNG or NMEA0183 but not both at the same time, so it's possible - especially if you have two-way NMEA0183 - that this is causing the AIS's software to crash, or similar.
Alternatively, perhaps you have a power-supply issue where the AIS's supply voltage is dipping when it tries to transmit and this is causing an internal networking failure.

It's not a common issue I've come across personally, so this is a bit speculative.

Regards,
Tom
