I have spent some time today investigating the pinouts and behavior of the RJ45 connections on the radio for the purpose of integrating with other things. I have also messaged BTWR to ask for the official information. I will post the results here in the near future.
One think I discovered today is what I consider to be an error in the manual. The pin numbers used in the manual for the RJ45 (8P8C) connector are backwards from the standard. So if you make you own cable and reverse the conductors based on the standard pin numbers, the cable will be incorrect. If using the standard pin numbers, Pins 5 and 7 need to be reversed end to end, not 2 and 4 as indicated in the manual. However, if you follow the graphic in the manual you will be fine.
I found the problem to my high swr on my gmrs radio. I was using the wrong connector connected to my new surcom sw 102 swr meter. it was reading 19.99 swr and now reading 1.4 or 1.5 swr and the watt output seems to be close using my 40 watt radio. Just a amature mistake. I am now so happy I can talk on it and not worry about blowing up my new radio. Now I have to figure out how to use repeaters.
Thanks for all your help
