Ok guys, i managed to try out the settings suggested by Mattias (and reconnect the coolant sensor, but still no trigger.
Rob, wasn't that relay just to give the vems a direct power feed to the battery?, i cant really remember. I do however have voltage at the CAS and i can see the voltage switching on my DVM.
I notice when i try to use the 'record trigger log' i only get a blank grey background screen, not a blue band as it shows on the demo video posted earlier, dont know if this is relevant?
