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 ordinary 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.
Timing and conditions
Example 1 of Long exposure
EXT HD
Continuous signal: 15.734 kHz (XC-ST50/ST30), 15.625 kHz (XC-ST50CE/30CE) Allowable frequency value 1%
EXT VD
VD interval(T): 262.5H or more (XC-ST50/ST30), 312.5H or more (XC-ST50CE/30CE) and 1 second or less (Recommended)
Four or more VD pulses are required.
