6.2.3. Pulse Width Control Mode

The exposure will start at the first HD after the trigger leading edge, and it stops between the first and second HD after the trigger trailing edge. An EEN pulse indicate the accumulation time, and a WEN pulse indicates that the resulting video is read out.

Refer to “7. Configuring the Camera.”

To use this mode:
Set function:	Trigger mode to “Pulse width control”. SW 1-4 to ON
	On PK8407: JP301 open, JP302 open, JP311 open.
	Accumulation to “Field”. SW 301-4 on PK8407 to OFF
	Scanning to “Non-interlaced”. SW 1-5 to ON
	Shutter Speed to “1/10,000”. SW 1-1 through 1-3 to ON
	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 can be >1H to <900H. (>64 ∝sec. to <60msec.)

•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
