How to operate in framing mode

1.The camera must be running in master mode.

•External sync signal cannot be present at power up.

2.Provide a LVDS active low “FRAME SEL” LVDS signal to pin 5 and pin 13 of the camera’s control connector (DB15).

READOUT TIME

EXPOSURE TIME

FRAME PULSE

1.Provide the LED with a trigger pulse that is active high during the camera’s exposure time.

•An inverted FRAME SEL pulse with LED driver could be used. This requires a LVDS receiver that will convert the FRAME SEL signal to TTL. This signal will turn ON a transistor or a FET to drive the LED light source.

•If a TTL signal is available from the frame grabber, this could directly drive the LED driver.
