Hi, Oleg I just tested the method 1. However, When I set the parameter TRIG_OUT = 0x00 and applied it, all the parameters could not save(Test it many times). So I removed the external signal line, and tested all of these, it made works. The frame num stopped growing. Another question is that parameters can not be saved when I change the trigger parameter(I remove the autoparameter*.* file in etc/elphel393), but other parameters probably can be saved success. Can you have other suggestion?

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.

I have some new questions about external trigger.

But I stopped the trigger board signal, I also could update the image(10hz). I wanted to konw that how can I test the external trigger signal work? Because when i stop external source trigger signal, it could receive images too. ________________________________ ----------------------------------------------------------- Best Regrad!

If it does not - then please update the firmware to 20180511<https://wiki.elphel.com/wiki/10393_manual#Firmware.2Fsoftware_update>. There was a bug in the clock driver we had to fix a while ago.

Is that OK? And now our situation is there are timestamps in EXIF header. But it is not the kernel's system time. e.g. the timestamp in EXIF may be 2018/09/14 but actually system's date is 2018/09/18. How can i fix it? Thanks.

Trigger 393 - ElphelWiki - wiki.elphel.com<https://wiki.elphel.com/wiki/Trigger_393> wiki.elphel.com<http://wiki.elphel.com> Description. 10389 board is required. The triggering is used for one or several cameras synchronization or setting the frame rate (or fps). The conditions of the trigger can be generated either internally or externally. Camera channels should be in triggered mode (TRIG=4) and have correct TRIG_PERIOD. Then all channels will be exactly synchronized. If you set TRIG_PERIOD to some "even" number (like exactly 10fps with TRIG_PERIOD=10000000), then timestamps will have all digits but seconds and tenths of a second the same for all frames.

This timestamp was the same with camera system timestamp. And the other way, each image had its exif information that contained the real timestamp. But this timestamp from exif information was not the same with system timestamp. So can you provided some detials about where was the exif timestamp from. And how did i do can solve this problem. (i had synchronized the camera system time with the GPS timestamp.) ________________________________ ----------------------------------------------------------- Best Regrad!
