Dear Nandi,

Thank you for the reply.

When the system alarms are outputting 'NMEA data' is the eS alarming 'no GPS source'?

Different devices have different time lapses when listening for NMEA data. This could be an issue with the internal GPS dropping out and regaining a fix but the NMEA sentence is not being received by the network in time to prevent it alarming. Do your instruments have the ability to alarm for different data loss i.e no GPS fix or is it only no NMEA? The alarm notifications can assist in identifying problems.

You could try a different NMEA 0183 port on the eS to see if this resolves the issue, you could also try isolating the network to smaller systems i.e just the eS and autopilot to see if the issue continues or it may highlight another area that needs addressing on the NMEA 0183 network.

You can send the eS unit back to us for test and repair here.

Many Thanks
Louise
