Specifications of the Trigger
Pulse
• Input impedance; 10 k
Ω 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
µ
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
µ
sec to 250 msec.
Exposure time = Trigger pulse width + 97
µsec (EIA)
Trigger pulse width + 120
µsec (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.

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.)

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