Hi, I've contacted people in the industry but everyone is stumped about this cruise control unit I bought off ebay. OEM does not support it, as we know they are out of business.

It is a SCS/Frigette part#202-3235. What stumps everyone is that it does not have the DIP switches but instead has some sort of interface pins that should be connected to a computer. Does anybody have more info on this? I have included a photo of the PCB of the unit, compared with a photo of the PCB of the older unit it is meant to replace.

Thanks

ICSP most likely stands for In Circuit Serial Programming. It is most likely an interface to write firmware to the main processor - not to update settings.

Always fun to see how modern technology has drastically reduced component count. Chances are that all the dip switch settings are now programming through a separate interface (ie hold UP button for 10 seconds to enter programming mode (this is just an example, I know nothing about the unit).
