DLP4500: Trigger out

Emilie Cuillery

Part Number: DLP4500

Dear Ti support, Hi !

I have the DLP LightCrafter4500 and I want to use it to trigger my camera DCC3240C: https://www.thorlabs.com/thorproduct.cfm?partnumber=DCC3240C

My DLP trigger output 2 is a - 3.3V signal but the trigger level low of the camera is 0-1V and the trigger level high is 5-24V.

I had the same problem with my previous camera that I could not trigger because of that. It seems that many cameras cannot be triggered using the light output voltage. Am I missing something ? Do you have any advice so I could use my light to trigger my camera ? (I am not familiar with the electrical engineering even if I have the very basics of it)

Thank you very much for you support,

Have a nice day,

Emilie

Hello Emilie,

You could take a look into using a level translator to take the EVM output voltage to the voltage required by your camera. See this application note about level translation: www.ti.com/.../scea040.pdf. Also see some of our level shifting products at www.ti.com/.../overview.html.

Thanks,
Kyle
