RV-C Bus Communication:
RV-C is a communications
protocol based on CAN that is
used for control, coordination,
and diagnostics.
Note : Anyone that intends on
connecting to the RV-C bus
should have a knowledge of the
RV-C specification. For more
information on RV-C protocol go
to: http://www.rv-c.com
The sensors use a default source address of 72 and SPN-ISB
instances are 0 for fresh, 1 for black, 2 for grey and 18 for galley
(depending how the display is equipped). The LPG sensor uses a
default source address of 73 and a SPN-ISB instance of 3.
1. By disabling the LPG or 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 in
the image above. 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.
