Operation
3.8 Using the RV-C Connector
Magnum inverters and accessories normally communicate using proprietary MagNet serial data thru
the NETWORK port. On the MSH3012RV inverter, this MagNet data is converted internally to RV-C
compliant protocol and provided through the RV-C connector. This allows the RV-C connector to
be connected to a RV-C network in your coach, so that you can monitor and control this inverter
and its connected accessories with your coach’s RV-C compliant display.
Note:
The MSH3012RV inverter can only
receive settings and commands
from one device (i.e.,
RV-C device or Magnum remote) at a time.
3.8.1 LED
Indicator
Use the RV-C’s LED indicator—located just above the RV-C connector port (see Figure 3-12)—to
determine the status of the RV-C port. When power is
fi
rst applied to the inverter, the RV-C status
indicator (yellow LED) comes on for 2 seconds, then goes off.
When the RV-C connector port is connected to an active RV-C network bus/backbone, the inverter’s
RV-C port becomes active. When the RV-C port is active, the RV-C status indicator will blink. Use
Table 3-3 below and the RV-C port indicator to determine the RV-C port’s operation.
Note: The RV-C status LED will only come on/blink if the MSH3012RV is connected to an active
RV-C network.
Table 3-3, Operating Status For RV-C Port
LED
Operating Status
Blinks*
When the RV-C status indicator continuously blinks and pauses, the RV-C port
is active and able to communicate on the RV-C network.
OFF
The RV-C port is not active and is not detecting data or power from the RV-C
network.
The RV-C status indicator (yellow LED) will rapidly blink and pause continuously as described
below to indicate which address it has been assigned:
1 blink, then
a pause*
Normal operation and the inverter has been assigned with address #1 on the
RV-C network bus
2 blinks, then
a pause*
Normal operation and the inverter has been assigned with address #2 on the
RV-C network bus
Note*: LED (yellow) blink = Rapidly blinks on and off (0.2 seconds on and 0.2 seconds off); pause =
1 second off.
