Hello, In the link you used the internal trigger generator is working and is routed out to the sync cable (which is probably self-looped - input and output wires are connected):
Try: *1.* Set TRIG_OUT=0x0 to stop internal pulses at the sync cable output: # old link: http://192.168.0.9/parsedit.php?sensor_port=0&immediate&TRIG_CONDITION=0x95555&TRIG_OUT=0x66555&TRIG_PERIOD=100000000&TRIG=4 # new link: http://192.168.0.9/parsedit.php?sensor_port=0&immediate&TRIG_CONDITION=0x95555&; > *TRIG_OUT=0x0*&TRIG_PERIOD=100000000&TRIG=4 *or * *2.* If the sync cable inputs and outputs connected. Disconnect the wires from each other and apply your trigger source: signal or "+" - to Black wire, ground or "-" - to Green wire. Please, check the wire colors and pinout here <https://wiki.elphel.com/wiki/103891>. Let us know if that worked. Thanks. I'll update our docs to make them clear.
