We have 2 FCP suites running the same setup FCP 5.1.2 with Kona LSe cards w/KCP 3.2. One box is continuously resetting the reference from Ref In to Freerun. Both suites are fed from the same generator in our rack. Our third system is a MacPro running FCP 5.1.2 with a Kona 3 w/KCP 3.1. This also receives sync from the same generator(Tektronix SPG 422). The MacPro doesnt have any issues at all. Before I go switching cables around does the KCP jump back if refernce is lost? I was leading to believe there might be a bad cable or connection sending refernce to the troubled suite. Therfore if refernce is lost KCP will fall back to freerun.
