• STROBE OUT (Output): STROBE OUT is an LVTTL output (0 to 3.3 V) that is high during the actual sensor
exposure time. STROBE OUT is typically used to synchronize an external flash lamp or other device with
the camera.
• TRIGGER IN (Input): TRIGGER IN is an LVTTL input (0 to 3.3 V) used to trigger exposures on the camera.
Transitions can occur from the HIGH to LOW states or LOW to HIGH, as selected using the ThorCam
interface. Default is Low to High. Minimum Trigger Pulse-width is 100 µs. Maximum trigger voltage may
not exceed +5 V or go below -0.7 V.
