To set Restart/Reset mode
The information on one screen can be extracted at any
time by externally inputting a restart/reset signal (HD/
VD). To enter this mode, set DIP switches 6, 7, and 8
on the rear panel of the camera as shown in the figure
below. The setting is especially effective for the
operation explained below.
The Restart/Reset function extends the CCD
accumulation time, resulting in a highly sensitive
image. This function is effective when you cannot gain
satisfactory sensitivity under normal operating
conditions, or when you want to observe a moving
object. Extend the VD interval (T) period between
external VD pulses.

Frame Accumulation (Factory setting)
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
Continuous signal: 15.734 kHz (XC-EU50) Allowable frequency value ±1%,
15.625 kHz (XC-EU50CE) Allowable frequency value ±1%
VD interval (T): 262.5 H or more (XC-EU50) and less than 1 second (Recommended),
312.5 H or more (XC-EU50CE) and less than 1 second (Recommended)
Four or more VD pulses are required.
Some white spots may appear after a long exposure.
