Peter, that means that both trigger output and trigger input are operational. This test (it is just a php script) turns the trigger output off, measures trigger input, then turns output on and measures input again. If input was "off" in the first measurement and "on" in the second the program concludes that this is a "master" camera - the one that drives the synchronization pair of wires. You may connect oscilloscope between them and see these signals (the trigger input is opto-isolated, but the output is not, one of the signals is connected to camera ground).
If you run the camera from the FPGA trigger (TRIG=4, TRIG_CONDITION=0) you may make the output generate pulse before each frame by setting TRIG_OUT.
