Hi, Andrey!
Thany you for your patience to answer our questions!
I have some new questions about external trigger. When I set the trigger
parameter as the page
http://192.168.0.9/parsedit.php?sensor_port=0&immediate&TRIG_CONDITION=0x95555&TRIG_OUT=0x66555&TRIG_PERIOD=10000000&TRIG=4,<http://192.168.0.9/parsedit.php?sensor_port=0&immediate&TRIG_CONDITION=0x95555&TRIG_OUT=0x66555&TRIG_PERIOD=100000000&TRIG=4,>
and I made the trigger board pulsing out the signal(10HZ), I found we could
get 10 images. 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.

Hello,
Here are a couple commands (in linux) that can help to check and sync the
system clock:
- Compare PC and camera clock:
~$ ssh root@192.168.0.9<mailto:root@192.168.0.9> date;date -u
- Write PC time into camera clock:
~$ ssh root@192.168.0.9<mailto:root@192.168.0.9> "date -s @`( date -u +"%s" )`
&& hwclock -w"
After setting the system clock check if the time survives the reboot. 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.
Regards,
Oleg

Hi, Andrey,
We use default configuration(TRIG=4 and TRIG_PERIOD=25000000). 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.
Best,
David

Winston,
What trigger settings do you use ( https://wiki.elphel.com/wiki/Trigger_393 )?
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.

Hi, Andrey!
I captured some images form camera with the timestamp image name. 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.)

Winston,
I could get the info from the 192.168.0.9:2323<http://192.168.0.9:2323>. This
web could help me to get some information. But if I tried the
http://192.168.0.9:2323/timestamp_name, the timestamp file saved web did not
appear. How did I use it?
http://192.168.0.9:2323/pointer_value/img
Try the following:
1. get
diagnostics.php<https://git.elphel.com/Elphel/elphel-web-393/blob/master/src/diagnostics/diagnostics.php>
2. copy to 192.168.0.9:/www/pages/
3. In the browser open:
view-source:http://192.168.0.9/diagnostics.php?pointers
You will get xml output similar to this one:
<?xml version='1.0' standalone='yes'?>
<Document>
<camera ip='192.168.0.9'>
<port index='0' sensor='mt9p006, none, none, none' mux='none'>
<timestamps>
...
<ts frame='7290' ts='1526075540.347616'
ptr='pointer_value'>1526075540.347616</ts>
...
Take the pointer_value from the last <ts> for a particular port. Don't forget
to add "/img" or "/bimg".
If something does not work. Please send me your xml.
