Batboard

I have a UHF GR1225 Repeater c/w a ZR310 controller. The frq is 460.9250/465.9250 and i am using 2 users TPL code 179.9 and 186.2 which are working great. When i program DPL codes into the ZR310 i can't get the code to come through, i can only get TPL tones to work, but no DPL codes, what could i be doing wrong i wanted DPL code 506 and 664 and tried other codes but no DPL will work. Can anyone help me with this frustarating problem i have?

Thanks in advance and have a great day

John

John,
I've worked with a R1225 and ZR310 controller, and have had the same problem. In my situation, the controller was actually transmitting the DPL code inverted. We had to change all of our radios to receive inverted DPL. Try that and see if it works. I haven't figured out how to get it to transmit regular DPL. Let me know how you make out.
