Motorola R100 JAUX and
Compiled by Robert W. Meister WA1MIK
JAUX is wired to J3 on the QRN4314A interface board. J2 on the interface board is wired to the station control board mounted on the top cover. Pins with no information are Not Connected or Not Used. Almost all of the signals pass through buffer or inverter circuits on the interface board. The Direction is IN TO or OUT OF JAUX. This information is also presented in the R100 Instruction Manual starting on page 48 of the PDF file.

Interfacing common repeater controllers is easily done through the JAux connector with the exception of having to add a couple of wires to bring out a few additional signals. The CSI controller hookup sheet is VERY helpful here.
For D-Star controllers and such, the following connection points work very well
(this information was provided by Scott N3XCC):
Remember to program the rreceiver for carrier squelch and no PL/DPL transmit tone.
