The original KPG-4 used a DB-25 connector for the computer side. The back-shell contains the radio interface circuitry. Later Kenwood supplied cables did change to use the DB-9 connector for the computer connection. The change was made possible by the increasing use of leadless components.
You need to be in a true DOS environment for these older programs to run properly. Best to use an older computer that runs Win98 or XP and boot into DOS. I keep several older laptops around for just such occasions.

Thanks for the reply. I purchased the KPG-4 cable which is what I was trying to use and was using DOS. But I'm confused because the KPG-4 cable I bought
has a serial pin connector on the end going to the computer and you said it has a 25 pin connector on it. Should i have purchased one with a 25 Pin connector?
Thanks
Mike
