Anybody using the CNX-P2140 on an intel mac mini? Mine boots up fine but shuts down after a minute or so with the LEDs in the CNX-P2140 flashing.
I believe I have all the jumpers set correctly:
JP2: +5 (Although I don't have this output hooked up to anything yet)
JP4: Config 1
JP5: Mac mini Intel
I have a windows 7 64 bit laptop so no joy on the included software for softjumpers etc.
For testing I have the CNX-P2140 wired up to my subwoofer amp. +12 to +12, gnd to gnd, and the yellow "ignition" wire connected to the amp control wire coming from my head unit. Guess I should have tested that but I'm assuming that is at +12 as long as the head unit is on.
