Hello all, I, quickly, browsed through the archives, but didn't see this question asked / resolved. I am really hoping that someone has the knowledge and time to help with this. I am setting up an allstar node and running into things that I just don't know how to do. I need to know how to interface (get the right pins to the right pins) the Kenwood TKR-820 UHF repeater's 15-pin accessory port to the URI's 25-pin port. I really don't know which pins are necessary or which ones connect to which ones. I hope this made sense. Below, I have included the websites for the pin layouts of each of these two machines. Any help would be greatly appreciated.
