6.4.5. J4 4-Pin Power Connector
J4 is used for primary and secondary input voltages for the 12RII-LC and 12RII-SR radio systems. The J4 cable plugs into J1-
J4 on the Power Supply Board. J4 typical signal interfaces are shown in the table below.

A +74VDC
B 13 VDC Com
C -74VDC
D +13 VDC
6.4.6. J5 23-Pin Power & Control
J5 is used for input power, control and audio signal interfaces on the 12RII-RC radio. The J5 cable assembly plugs into J1-J4
on the Power Supply Board and J5 & J6 on the Radio Control Board.
The Following tables are the currently defined power interfaces used on 74V, 37V and 13V AAR Remote Control Radio
systems.
