EXTERNAL TRIGGERING

}The DP30BW can input or output an external trigger signal to record still images or control a commercially available

shutter.

Connecting the BNC triggering cable

Operation using the trigger input

· The trigger signal input from an external device can be used to trigger recording of still images using the DP-BSW basic

software.

· The trigger input should be a positive logic signal and its positive-going edge is detected. (Pulse duration: 5 ms or more)

The trigger input is not compatible with random triggering. Due to the time lag of 200 ms to 1 sec after the trigger input,

it is not possible to synchronize the external trigger input and start of exposure completely.

· The trigger input is TTL compatible.
