Looking at the voltage diagram Pin8 CLI and hanger is biased high to look for the hanger button (or CP1). You might check to make sure some nimrod hasn't jumper-ed Pin8 to ground on the front board instead of soldering CP1 to disable hanger function. I only use the OEM USB cables, and since they have always worked (senior moments aside) I haven't bothered to explore the levels and rates.

Looks like Pin1 8V+ is used to power the cable components for plain RS-232 serial connections without power from the PC, but I am not positive. If the chip doesn't decode the signal it won't send, or if it sends something may be garbling the data. The front board chip looks for an instruction on CLI, then responds on CLO.

Looks like you are down to trial and error creating a OPC1122 clone. Starting with the F5/621 and F1/221-series, 2-7-8 via OPC1122 became the standard this has carried forward to F1/2721 and the F5/6xxx radios and FR5/6000 repeaters.

Often the Kenwood software is less than $100 so don't be a cheapskate just purchase it.įor M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. Typically each series or individual radio requires its own software package. Please use Google or some other search engine to find a dealer that sells the software.

The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). To obtain Motorola software see the Sticky in the Motorola forum. It is YOUR responsibility to properly word your request. We do not want any hurt feelings when your vague post is mistaken for a free request.
