	* It's easy to modify the cable to trigger itself and other multiple cameras.		* It's easy to modify the cable to trigger itself and other multiple cameras by connecting together red and black wires (+) and white with green (-). For self-testing (external trigger loop back) it is sufficient, for LED - connect anode to "+" (red+black), cathode - to "-" (white+green).

			Turn on external trigger loop back (cable should be inserted):
			http://192.168.0.9/parsedit.php?sensor_port=0&immediate&TRIG_CONDITION=0x80000&TRIG_OUT=0x66555&TRIG_PERIOD=25000000&TRIG=4

			Or use interactive page:
			http://192.168.0.9/parsedit.php?sensor_port=0&embed=0.25&title=Parameters+for+groups:+trigger+&TRIG&TRIG_MASTER&TRIG_CONDITION=0x80000&TRIG_DELAY&TRIG_OUT=0x66555&TRIG_PERIOD=25000000&TRIG_BITLENGTH&EXTERN_TIMESTAMP&XMIT_TIMESTAMP&TRIG_DECIMATE&THIS_FRAME&refresh

			And then click "Apply" button.

			Both variants should turn camera into external loop back mode with 0.25s period (4 fps). If the page (and the camera) hangs, the loop is not working. For troubleshooting you may restart the camera, open
			http://192.168.0.9/parsedit.php?sensor_port=0&embed=0.25&title=Parameters+for+groups:+trigger+&TRIG&TRIG_MASTER&TRIG_CONDITION=0&TRIG_DELAY&TRIG_OUT=0x66555&TRIG_PERIOD=25000000&TRIG_BITLENGTH&EXTERN_TIMESTAMP&XMIT_TIMESTAMP&TRIG_DECIMATE&THIS_FRAME&refresh

			and press "apply". The camera will continue using internal trigger (TRIG_CONDITION=0) but still generate trigger output (TRIG_OUT=0x66555). This output can be controlled by either the LED soldered to the cable or the oscilloscope (ground to the green+white, signal - red+black - it should show not just a pulse but a encoded timestamp some 22us long. Changing TRIG_CONDITION to 0x80000 (enter 80000 into "New value/Hex" field without "0x" and press "Apply") should activate loop back, and if it works then "Refresh" button should cause new "THIS_FRAME" field value. If it does not work - trigger input does not reach camera - bad cable or connector.

			* The simplest synchronization would be making a custom audio cable to sync all cameras in the system
			* In case there are multiple cameras in the same enclosure it might make sense to sync them by chaining using 4-pin flex cables
