POWER UNIT (Figure 5)
A. SENSOR Connector (J5) - for cable to sensor.
B. CONT/IND Connector (J7) - for cable to Control/Indicator.
C. DATA OUT Connector (J4) - provides analog signal outputs.
D. POWER IN Connector (J1) - for conn28 VDC.
E. PRESSURE – to connect to optional pressure sensor
F. RS-232—serial data output (9600 Baud 8-N-1)
The power unit is no longer furnished with a shock-mounted base as we have determined
that one should not be required for most aircraft installations. If shock mounts are deemed
necessary, they are made by Barry Controls and the part number is Barrymount L44-
BA(M)-2. (Use BAM for metric and BA for standard). Install one on each corner of the
Power unit using the screw holes on the blue mounting brackets on the bottom. You will
need a total of 4 Barrymounts.
