6.4.7. J6 12-Pin Accessory
The 12-Pin Accessory connector is a typical option on the 12RII-LC radio. The J6 cable assembly plugs into J6 on the Radio
Control Board. The typical interface signals are shown below.
Note: As an alternate for some applications a 15 pin connector is supplied. Signal interface is identical except for pins M &
N. Speaker outputs are replaced with I/O-3 & I/O-4 signals.
