Short answer -Yes, ignition on bike toggled many times, also pulled fuse to EZcan. No 'reset of virtual fuse' as expected, had a fuse overload been the cause.
Long answer - I analysed from first principals, using multimeter to trace actual voltages. Long sequence of events, in no particular order: Cam LEDs on controller found to be not lit, so enabled wifi on phone & Innovv app to see cam not powered up/online. As cam is powered by Hex EZCan accessory circuit with power, earth & trigger, used multimeter to confirm power was coming out of EZcan but Innov controller relay not being activated by trigger, ergo: trigger not alive. Had to go buy very long USB cable to connect EZcan to Mac Mini inside house. Ran software & it showed all configured circuits active, with current limits as I had set months ago. Didn't look at diagnostics for cam's accessory circuit (mistake) - just toggled that circuit off & on (with green slider button, IIRC). Innovv camera then sprung to life & now all good.
Question is: Why does EZcan software interface show accessory circuit is on & active when it was clearly "configured to be active" but "not on/active".
According to doco, cycling the power to EZcan should reset any "blown virtual fuse", but that didn't work for me. Only toggling circuit OFf then ON again worked.
Would be inconvenient if I was away from home/computer! I carry an iPhone, so software that used BT/USB/wifi from EZcan to phone would be a great long-trrm fix.
