Mode Setting

Restart/Reset

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.

Long exposure

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.

Note

Some white spots may appear after a long exposure.

EXT VD

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),

312.5H or more (XC-EU50CE) and less than 1 second (Recommended) Four or more VD pulses are required.

Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
