Hi folks,

I've got a remote mount XTL5000 with a W7 that I'm trying to bring up to modern firmware. The current version in the radio is R05.00.00, which is pretty much ancient from what I understand. I can read/write the radio no problems from the rear USB but I can't get it to take a firmware update (using a legit iButton). I've seen conflicting information saying that firmware updates via USB may not be supported in this old firmware... ok, fair enough. So I home brewed a rear serial cable... and I can't get it to do anything at all. Period. Does anyone have the pinout for the HKN6160B serial cable? From what I understand it's just RXD/TXD/RTS/CTS going to pins 5, 6, 10 & 11 on the rear connector. Am I missing something else? Any tips or suggestions muchly appreciated!
