Its not so bad on my bench. With the right software you should be able to program it no problem. simple comm connection with a null modem cable be sure to use the top port on the ccb as the lower 1 is for smdr .f4 f37 is what you need any of the f4 series should work don't let the unrecognized message software version scare you. If you cant dig up a copy of the f4 software email me and I'll hook you up. But since its a used car dealer I got this used ksu only talked on by this little old lady on sunday its cheap. LOL
