Mike, You have programmed active low for both COR and PL but it sounds as though you have not used command 005 to set the receiver access mode to require both COR and PL. By default it requires only COR for the repeater to go active. In that state the PL input will simply be ignored.
With command 005 you can set receiver and DTMF decoder access conditions. If you want to require both COR and PL for both repeater access and to send DTMF commands to the RLC-4, the proper command would be 005 1 3 3.
