![]() Only one pin is shared pin 4 and that's ground. If we stick with MaxTrac pin numbers from now on, we can see that the MaxTrac cable uses pins 4 and 7, and the MTR cable uses pins 2, 3, and 4. ![]() These are views looking into the RJ45 programming jacks on the two radios. It's said that a picture is worth a thousand words, so here's a graphical representation of the numbering schemes. ![]() However, after a little thought, I realized that the two radios can utilize one RJ45 cable if you wire it up properly. Because the two radios number the RJ45 pins differently, you must be careful how you make these cables up. The cable is wired as follows, using MTR pin numbers. ![]() The station uses the RS levels directly and only needs a simple three-wire serial connection. The interface is a single shared line that carries both transmit and receive data. ![]()
