Thermal eye 2620AS not working (solved)

Hello.

First, here's the manual for Thermal eye 2620AS, because we need it to discuss further:

















Today I try to play with it, it was bought as new and I didn't use it because it have a rare connector, however this time I soldered some cable direct on to it and just want to see if it works.

First I used the low voltage input, and because I don't have a 1.8-3.2v power source, so I use Li-ion battery with 2 IN4007 in series, but the camera did not work at all, despite I verified the voltage is in range. Then I tried the high voltage input, the camera's NUC shutter works, but no video output, I tried both 12v and 24v adapter.

What can be the problem?

Thanks.

Stating the obvious, but just to be sure....

Have you got pin 8 = ground ?
Otherwise no video out

Have you connected all the power pins as it says ?
Seems rather insistent that you need to connect the lot so that might actually be true, and you have a bit of a problem without the JST 14 way

All I have are the 13 ways from the 2000 so not much help.

regards
Bill

Sam,

Thank you very much for sharing the L3 core user manual. I have been after such information for some time just in case i get one of these cores.

Sam,

If I were testing this camera I would definitely use the high voltage input as that is the pre-regulator for the core and so provides better overvoltage protection etc. The low voltage input is positioned after the pre-regulator and an over voltage event here could be damaging to the cores regulator and even other components.

Note the grounding requirement of pin 7 and, as bill said, correct video output selection via the grounding of the video select pin.

An operating FFC shutter usually indicates a happy core that is running so this does sound like a video output selection issue. The board can also drive a KOPIN LCD and it may be running in that mode.

Hello Bill.
Thank you very much, err... okay I'm so stupid this time, I didn't connect pin 7 and 8 to ground...
I'll report back when I have time to fix that and test again.
Sam
