(4)FLD Output / FRM Output Selection (SW1 DIP7) (Initial-Factory-Setting: OFF)
OFF: Field output
ON: Frame output
Under OFF (= FLD) setting, only the 1st field data is output in response to one trigger
input. Under ON (= FRM) setting, both the 1st and 2nd field (=1 frame) data are output
in response to one trigger input. Under the FRM output setting, CCD exposure is done
twice inside the camera. This causes 1-field timing delay.
(5)RTS (Random Trigger Shutter) Pulse Control
The camera starts light-exposure at the TRIG signal falling-edge timing. The
exposure-time is determined by pulse length. Be sure to set the pulse interval longer
than 1H (approximately 103
μ
s). The TRIG interval should be set longer than 2V
(approximately 133ms).
