Hi Team,

Can I ask some questions about the DLP® LightCrafter™ 6500 and 9000 Evaluation Module manual?

For the trigger input in Table 4-1. (Trigger Input Connector Pins)

what is the difference between Trigger In 1 Supply and Trigger In 1.

Could you please also let me know if I want to input a 3.3V TTL signal, what I should send to the 6 pins connector?

Thank you.

Hello Mark,

Section 1.6.2 of the LightCrafter(TM) User's Guide discusses the voltage selectors for both the input and output triggers.

Referring to the schematic, it looks like you need to put a jumper on pins 1&2 of J22 to enable a 3.3V TRIGGER1_IN. You would then put your 3.3V trigger on pin2 and GND on Pin 3 of J23:

Hopefully that helps.
