If ECU B data fails, no data is sent on ECU B.
Status LED
The RDAC CAN has a greed status LED indicator.
Single flash: RDAC CAN is powered and working but there is not data received on the ECU
CAN bus.
Double flash: RDAC CAN is powered and working, data is being received on the ECU CAN
bus.
Error codes
The RDAC CAN interface transmits the value 9001 as RPM in case there is no data received
from a UL Power ECU.
As the EFIS should be setup for 1.0 pulses per revolution (RPM setup menu) this results in
the value 9001 displayed on the EFIS in this case.
If no data is received from the Rotax ECU for one second, all values will be transmitted as
“zero” (except for the RPM which is transmitted as 9001).
Tip: If the RPM overs peed alarm is set and enabled, this will trigger the alarm on the EFIS.
G2 EFIS setup
The G2 EFIS (Odyssey/Voyager) have two RDAC inputs intended for use with MGL's
traditional RDAC systems.
Starting from RDAC model XF, the CAN bus is favored for the RDAC data feed connection.
The G2 needs to be told that you would like to use the CAN bus for the RDAC. You do this in
the “Engine monitoring setup”:
There is no setup required for the iEFIS as the iEFIS uses only the CAN bus for RDAC
connections.
With the traditional RDAC devices fuel pressure input and current sensor inputs used spare
RDAC inputs and this required selection of the inputs as needed.
With the CAN based RDAC units this is not required as the CAN based systems have
dedicated inputs for these senders and the input selections are blanked out.
Note: G2 RDAC on CAN bus is supported from software version 1.1.0.0 or higher.
