Part Number: DLP4500
I'm trying to figure out how to set the output triggering to 3.3V, and am confused how to use the J13 and J15 pins to accomplish this. I've read the dlp4500 manual but the wording is too sparse and I'm not sure how to actually use the pins to select the output triggering voltage. Please do not just refer me to the manual.
I assume you are using the LightCrafter 4500 EVM in this case.
Have you seen the schematic available in the reference design page?: https://www.ti.com/lit/df/tidr157a/tidr157a.pdf
The pin assignments for J13 and J15 are marked in a bit more detail there. You need to install the header onto the right pair of connectors to get the output you want. For example, on J3 for 1.8V you would install the header for pins 5 and 6, while for 3.3V you would isntall the header onto pins 3 and 4. In this case, you would only want to install a single jumper between two pins in any configuration.
I hope this helps. Let me know if you would like a more detailed explanation.

Thanks, finally the required information is provided. My projector came with what looks as shorts across pins 3-4 (see picture). I wasn't able to pull these off, but I need 3.3V anyway. Is this part what you mean by a header that shorts the pins?

We are looking into your query and will get back to you before the end of 09/14/20.
In reply to Mayank Khandelwal:
Can you check whether those two pins (3,4 of J13/J15) are shorted or not using a mulimeter? Can you once again try pulling that jumper out? If you are not able to do it and if you cannot check whether the pins are shorted or not, then I would suggest you to contact TI customer service center.
Thanks Mayank, I've confirmed that the J13 and J15 pins are shorted to provide 3.3V output for the output trigger. I think that I will need to buy a hirose converter cable to interface with my Basler Ace camera.
