SC20 does not show in item list on FI70

[NornaBiron]

Hello,
I recently installed my SC20 compass in a simple N2K network with a FI70 display and a Vesper8000 AIS.
When I try to configure the SC20 from the FI70 it does not show up on the device list so I cannot configure it. Heading however is shown OK. Also all the PGN's of the SC20 are shown in the PGN list. The same happens when I disconnect the Vesper.
Should I use the PC configuration tool or is there an other trick to let the SC20 be shown in the network?

The SCX20?
It should show up in the sensor list. It sounds like something on the bus isn't correct.

The same happens when I disconnect the Vesper.

What exactly is happening when you disconnect the vesper?
