6.2.2. Edge Pre-select Mode

The exposure will start at the first HD after the trigger leading edge, and it stops after the selected shutter time, and the resulting video is read out.

An EEN pulse indicate the accumulation time, and a WEN pulse that the resulting video read out. Refer to “7. Configuring the Camera.”

To use this mode:
Set function:	Trigger mode to “Edge pre-select”. SW 1-4 to ON
	On PK8407: JP301 open, JP302 open, JP331 short. Factory setting.
	Accumulation to “Field”. SW 301-4 to OFF
	Scanning to “Non-interlaced”. SW 1-5 to ON
	“Shutter Speed”. SW 1-1 through 1-3 to optimum
	Other functions
Input:	Ext. trigger to pin 5 on 6-pin connector.
	Ext HD to pin 6 on 12 pin connector. (If used).

Important notes on using this mode.

•The duration of the trigger should be >1H. (>64∝sec.)

•To avoid 1H jitter it is recommended to synchronize the trigger to HD. (See fig. 11.)

•A new trigger can not be applied before WEN is high
