General
The RDAC CAN interface forms the bridge between the UL Power ECU and an MGL Avionics
G2 EFIS system and iEFIS systems.
The RDAC CAN interface provides the following:
a) CAN bus Interface to ULP ECU A with fallback to ECU B on ECU A failure
b) Interface to ULP ECU system via RS232 port
c) 2 fuel level sender inputs with internal pullups suitable for resistive senders. Pullup
resistors can be disabled via dip switch allowing senders with a voltage output to be
connected.
d) Input for a DC current monitor centered around 2.5V (range 0.5-4.5V).
The RDAC CAN emulates the RDAC XF system.
Data connections:
Connect the RDAC EFIS CAN to the CAN interface of the EFIS.
Observe CAN bus termination resistor recommendations for this connection.
UP Power engine data
The RDAC CAN provides the following engine data from the UL Power interface:
RPM
Please configure your EFIS for 1.0 pulses per revolution.
