Raymarine forum

I installed a Maretron J2K100 J1939 to NMEA 2000 gateway for use with my generator. I connected it to the SeaTalk(ng) network via the raymarine SeaTalk(ng) to NMEA2000 adapter. The device functions properly on the network, however when connected, all of the Raymarine devices (p70r, e127, i70) are unable to select data source. It returns a message stating that it was unable to select data source and to refer to the manual.

When I unplug the J2K100 the problem goes away. Any idea what the issue could be?
