Good evening y'all got a question. If any of you all hooked one of these up before I got a Motorola r 1225 repeater that I would like to hook this controller too. I would like to know how and what I need to do for programming the repeater to make this work. I appreciate all who come back. Been working on this for a couple hours zetron 37 repeaterman controller I'm pretty sure I got the pins where they need to go to hook it up. When I press the disable button on controller status light goes off and transmit light engage. It has a constant carrier keying up the repeater no audio when trying to transmit through it either. Hopefully somebody on here could give me a pinout diagram to hook this up and also what to program into the repeater I tried different things and still doing the same results. Thank you
