Make sure that the external HD/VD phases against the standard central phase are as shown in the figure above. Invalid signal input may cause an error in the internal reset.

When you restart/reset the camera or operate the camera by inputting an external trigger shutter pulse, the Vsync signal for the image is output 1 H later from the external VD.

Normal:

HD/VD continuous (EIA/CCIR frequencies: Maintained. Timing: See the above figure.)

Restart/Reset and /External trigger shutter

HD continuous/VD (Reset): Any timing if the phase with HD is within the above range.

•Input impedance; 10 kΩ or more.

•The voltage and pulse width used are measured at pin 11 of a 12-pin multi-connector on the rear panel.

•If you set the trigger pulse with the DIP switches, use the 100 ∝s to 1/4 sec pulse width.

Setting the external shutter speed with the trigger pulse width

Set all DIP switches (1 to 4 on the rear panel) to 0. You can obtain an arbitrary shutter speed by setting the trigger pulse width to the range of 2 ∝sec to 250 msec.

Exposure time = Trigger pulse width + 97 ∝sec (EIA) Trigger pulse width + 120 ∝sec (CCIR)

Notes

•The DIP switch 5 position is optional. (The field setting is recommended.) The field setting can obtain a sensitivity that is twice that of the frame setting.

•If you input a new trigger pulse before the video signal output for the previous trigger pulse is output completely, an incorrect video signal will be output.
