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).

EXPOSURE TIME 

 
 

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.
