Does anyone know if the RCM3700 and RCM4000 programming cable is the same? I have a RCM4000 kit and the connections look like they could fit a RCM3700
Yes, it will work on an RCM3700. The only 3000 based cores that cable won’t work with are the RCM3000 and RCM3100 lines, which use a 2mm pitch connector instead of the 1.27mm on newer modules. The signals are the same though, just a connector issue for the RCM3000 and RCM3100.
