RESTART RESET (R.R)
The information on one screen can be extracted at any time by inputting a restart/reset signal (HD/VD) from the
outside. To enter this mode, set DIP switches 6, 7, and 8 on the rear panel of a camera as shown in the table below.
The setting is especially effective for the following operation.
Long exposure
A high-sensitivity image is obtained by extending the exposure time of the CCD when satisfactory sensitivity
cannot be obtained under other operating conditions or when observing the trail of a moving object.
The exposure time is determined by the VD interval (T) period between external VD pulses as follows.

Exposure time for Odd field
Exposure time for Even field
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-ES50/ES30, XC-EI50/XC-EI30)Allowable frequency value ±1%,
15.625 kHz (XC-ES50CE/ES30CE, XC-EI50CE/XC-EI30CE) Allowable frequency value ±1%
VD interval(T): 262.5H or more (XC-ES50/ES30, XC-EI50/XC-EI30) and less than 1 second (Recommended),
312.5H or more (XC-ES50CE/ES30CE, XC-EI50CE/XC-EI30CE) and less than 1 second (Recommended)
Four or more VD pulses are required.
