[CA] [CA11] E80 / E120 Radar issue

[TomHalfmoon]

HI

I have a E120-E80 Radar - AIS system that is work OK, no issues.

I want to swap the 2 MFD'd around between upper and lower helm stations.

Current configuration.
E120 (lower) version 5.69, Set to master, Radar cable connection, Map CF card installed, NMEA AIS connected, Seatalk HS connected.

E80 upper ver 5.69, set to repeater, Sea Talk HS connected.

ALL working

If I simply swap the 2 MFD around and reconnect all cables, set the e80 to master, e120 to repeated, swap CF Card, all works EXCEPT no Radar image.

Testing tried so far. disconnect Seatalk HS from network, E80 stand alone. Still not working. Swap e120 back as stand alone and all working OK.

Something about the e80 not accepting the radar signal??

Thanks for any suggestions.

Tom
