How to trigger two DMK 21BU04.H cameras?

Yin Lou

Hi,

Everybody! I'm a new man, Lou Yin. In my experiment, I want to use the DLP Lightcrafter to trigger two CCD cameras(DMK 21BU04.H ), but I don't know how to do it. And the serial number, PIN1(EXT_TRIG_VCC), PIN2(what???), PIN3(TRIG_OUT_CON), PIN4(what?????) of connector J7, is right ? Figure 1

Would you like to give me detail information about Trigger Connection setup?

Thank you!

Yin Lou,

Welcome to the DLP & MEMS E2E forum.

Please see this document: http://www.ti.com/lit/wp/dlpa032/dlpa032.pdf Using the DLP® LightCrafter™ to Trigger CCD Cameras from The Imaging Source®

PIN 3 (TRIG_OUT_CON) is an open drain signal, which means that you can trigger 2 cameras (or perhaps more) simultaneously by paralleling them.

Pascal DLP,

Thank you very much for your help!

After I saw that document and with the help of your answer,I draw a picture to show it. Fig. 1 Is it right? If not, what's the right? Can you introduce with a diagram?

Yin Lou,

I can't tell from your annotation (drawing) how you are wiring to the BNC connectors on the DMK21BU04.H cameras - follow the instructions in the referenced white paper. However, it looks like you have simply paralleled the connection to the two cameras. If it works with one, it should work with 2 cameras.
