I am able to (and have) transferred data from RR and updated firmware in both my radios with the supplied cables that came with these radios thru the FRONT RADIO PORT only. I wanted to use the REAR PORT to keep cable out of my way. However I think I need a different adapter than the one in pics below. I found this female/female 9 pin adapter that mates with my cables so I can use rear port. But it doesnt work. I ran a "detect" in Freescan and no matter what USB port on computer I use, and all the combinations Freescan searches for it still dosnt work. I am thinking this small adapter I found is a "GENDER CHANGER" and what I need is a "NULL MODEM"? Not sure what I need. I was hoping this would work to avoid more long cables in the way. And I was hesitant to order one online cause I dont know exactly what I need.
