[chirp_users] Help with Programming Rugged Radios RM-60

searched the site and scoured google, but came up with nothing. Apologies in advance for my lack of knowledge

Equipment: Windows 10 64bit Prolific USB to 3.5mm Cable running 3.2.0.0 Driver (as instructed by MIKLOR), correct identified port Rugged Radios RM60

Issue: Need to Program Radio with Chirp. Radio is not listed on Chirp site. I tried selecting other radios such as TYT or QYT as others had used, but software will say 'Radio did not enter clone mode' or radio not recognized, or something along those lines.

What am I missing? wrong cable/driver? incorrect radio being selected in Chirp? setting on radio? Do i have to use RT system's software and/or cable?

Thanks for any help you can provide.
