Find out which pins are TX and RX.  Connect them together and run a terminal program (I like CoolTerm: http://freeware.the-meiers.org/#CoolTerm).  Set the port for no handshake.  Anything you type should be echoed back.  That will at least confirm the cable is functioning.  There have been reports of fake Prolific chips, especially in cables sourced in China.

I read the posts on these problems.  Read CHIRP FAQs.

 I purchased a programming cable that was for BaoFeng U5 & B5/B6 and others.

I verified cable was fully inserted into radio. Did take an extra push to get fully inserted.

I had a hard time finding the correct Com Port, eventually found COM3 was being used by pulling cable and watching message appear and disappear accordingly.

Instructions are not clear whether to use just numeric designation (3) or full name (COM3), but neither worked.

Tried installing in other USB/Com ports and received error messages” “Device Driver software was not successfully installed” – Prolific USB-to-Serial Com Port (COM4) or COM5. 

Do not get this error when plugged Into COM3.

 

Notes:  Using Win 7, latest version of CHIRP 3-24-2014, USB Ver 2.0 ports.

 

What suggestions do you have?

Roger
