Restart/Reset - Sony XC-HR90 Technical Manual

Restart/Reset

Setting Restart/Reset Mode
The information on one screen can be extracted at any time by externally inputting restart/reset signals (HD/VD).
To enter this mode, set the trigger shutter switches (6 to 8) on the rear panel of the camera as shown in the figure
below.
To use restart/reset mode and partial scan mode simultaneously, set the partial scan mode switch (5) to ON (right
side).
Long exposure
The Restart/Reset function extends the CCD accumulation time, resulting in highly sensitive image capture. This
function is effective when you cannot gain satisfactory sensitivity under normal operating conditions, or when you
want to observe the trail of a moving object. Extend the VD interval (T) between external VD pulses.
