I have a consumer device (More specifically a Pioneer P99RS car audio head unit) that I need to operate remotely, with the front panel about 3 meters away from the main unit. The front panel connects to the main unit through an 18 way 1mm pitch FFC cable. What I need to do is extend this FFC cable from its original 8cm to about 3 metres. I'm fairly certain data loss won't be a problem since (as far as I understand) communication is just a few low speed serial interfaces.
The FFC cable is soldered onto the front panel but is detachable from the main unit, thus I'm thinking the easiest thing to do would be just using some sort of a breakout board in each end, connecting one of the boards directly to the front panel, the other board to the main unit through a new FFC cable, and interconnecting the two boards with CAT5/6 cables. Does that sound reasonable to you guys, or are there better ways?
Where can I find breakout boards (Or other viable solutions!) for 18way 1mm ffcs? I found a few forum links etc but they're all old and mostly dead.
