RV-C Bus Communication:
RV-C is a communications protocol based on CAN that is used for
control, coordination, and diagnostics.
1. By changing the FRESH/GREY/BLACK to zero senders, you
are disabling that sender's updates over the RV-C bus as
well.
2. The primary display has priority over the RV-C bus to check
levels. The secondary display will wait until the primary
display releases the bus before getting level readings.
3. The RV-C has a 4-pin connector as shown in the red box.
The connector pins conform to the RV-C standard.
4. Some displays have a wired connection as shown in the
red box in the image below. If this is what your display has,
connect the wiring according to the following table.
