So I have perused the site, and cannot find it:
Does anyone have the pinout (serial or USB) for a 51xx programming cable?
I assume you can use an XTS adapter on the radio itself.
Thank you,

Re: 51SL Programming cable
It works, I've built one, the one lead is reversed as Mancow states.
Also here is how to convert a XTS keyloader cable to work with you EFJ

I use my T3011DX keyloader with the EFJ 5100 w/o any issues.
