Overview
The XC-ST series is a monochrome video camera
module using an interline transfer CCD (Charge
Coupled Device) solid state image sensor.
Features
High image quality
The interline transfer CCD provides a high-resolution
image with 768 (H) ×494 (V) pixels (XC-ST51/ST50/
ST30) or 752 (H) ×582 (V) pixels (XC-ST51CE/
ST50CE/ST30CE).
Various mode settings
Rear panel switches allow the following mode settings.
•Gain: Auto/Fixed/Manual
•
γ
compensation
•Synchronized input/output
•Potential accumulation: FRAME/FIELD
•75 Ωtermination
•Trigger pulse polarity: +/–
•Shutter speed: Normal/Trigger shutter
External synchronization
HD (horizontal drive), VD (vertical drive) signals:
The camera module automatically determines
whether to operate in interlace or noninterlace
mode from the HD and VD signals input for
external synchronization.
VS (Video/Sync) signals: External synchronization
with a video or composite sync signal. (The unit
switches automatically between HD/VD and VS
synchronization.)
Internal sync signal output
You can output the HD and VD signals from the 12-
pin connector by changing the rear panel switch.
Electronic shutter function
Shutter speed can be selected from a wide range (1/125
to 1/10000 sec.) or in flickerless (FL) mode.
Body fixing
These mounting screw holes are provided in the
reference plane on the lower surface of the body,
allowing mounting with the absolute minimum
deviation of the optical axis.
The connector complies with the new EIAJ
12-pin pin assignment.
The new pin arrangement allows the connector to
accept a trigger pulse and a WEN signal.

1) This unit is shipped from the factory with the GAIN switch being set to F
(fix), so the Manual gain control knob is not operative unless the switch
setting is changed. When the GAIN switch is set to M (manual), you can
rotate this knob to adjust gain over the range 0 to 18 dB.

About the Electronic
Shutter
There are two shutter types: normal shutter and
external trigger shutter. Select them with the DIP
switches on the rear panel.
DIP Switches on the Rear Panel
Normal Shutter
This mode provides continuous video output with the
electronic shutter selected by switches to capture a
high-speed moving object clearly.
Rear panel
DIP switches
Switches 1 to 4: Shutter speed
Switch 5: Potential accumulation mode
Switches 6 to 8: Restart reset/External trigger
shutter mode switch 1) If you set the mode to flickerless, the positions of DIP
switches 1 to 3 are optional.
Note
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.
ExternalTrigger Shutter
By inputting an external trigger pulse, the camera is
able to capture fast-moving objects clearly.
For more information, see “External Trigger Shutter” (page
12).

Restart/Reset
To Set 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.
The Reset/Restart mode is especially effective for frame
image output with long exposure or a strobe light.
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.
