XC-E series
OUTLINE
The XC-ES30/30CE, XC-ES50/50CE, XC-EI30/30CE, and XC-EI50/50CE are industrial black-and-white video camera
modules, each using a 1/3- or 1/2-inch IT CCD . The 1/3- and 1/2-inch C mount commonly used in industrial applications
implements compact size and lightweight. Switching of each mode on the rear panel, which has been installed from
the XC-ST series, is followed to provide improved operability. The XC-EI series uses a CCD which is sensitive on a
near infrared area to capture a clear image even in low-intensity illumination. As with the existing devices, the XCES30/30CE, XC-ES50/50CE, XC-EI30/30CE, and XC-EI50/50CE incorporate significant shock and vibration resistance
to support installation on FA equipment.
MAIN FEATURES
1/3" and 1/2" IT CCD
A CCD sensitive on a near infrared area is used for the XC-EI series.
External trigger shutter function
(XC-ES50/ES30, XC-EI50/EI30: 1/4 to 1/10,000 seconds,
XC-ES50CE/ES30CE, XC-EI50CE/EI30CE: 1/4 to 1/8,000 seconds)
Restart Reset (R.R) function
Inputting HD and VD signals (2 VD or more) continuously from the outside can catch one image at arbitrary time
and control the stored CCD.
This function is used for long exposures and strobe with frame image output.
Synchronization system: Internal/external HD/VD
Inputting an HD/VD signal from the outside automatically establishes external synchronization.
This function is effective for controlling multiple cameras efficiently from the external system.
Setting each mode on rear panel
The setting of each mode can be changed by the DIP switch.
Almost all switches are located on the rear panel. This feature permits easy setting after equipment is installed.
Compact and lightweight
Compared to the existing devices, the size and weight are reduced widely.
Each of the XC-ES30/30CE, XC-ES50/50CE, XC-EI30/30CE, and XC-EI50/50CE can be used in applications
using two-piece cameras.

ELECTRONIC SHUTTER
External trigger shutter
These modes are used to capture one image (one field) per trigger pulse.
Set DIP switches 6, 7, and 8 on the rear panel to mode 1 or 2. (Refer to the table below.)
When the trigger pulse width is 1/3 sec or more, the output signal is switched to a normal video signal.
There are two modes for timing in which a video signal is obtained.
• Mode 1 (Non-reset mode)
In this mode, a video signal synchronized with a VD signal is output after a trigger pulse is input.
•A video signal is synchronized with the external VD signal when an external HD/VD signal is input.
•A video signal is synchronized with an internal VD signal when no external HD/VD signal is input.
• Mode 2 (Reset mode)
In this mode, an internal video signal is output from a trigger pulse after a certain period of time.
Video sync is always fixed with odd field for XC-ST70 and even field for XC-ST70CE.
For more details of each timing chart, refer to pages 16 to 23.

by 1 and 2 in the figure). For the input e xcept described abov e , the operation cannot be ensured. If the
external VD signal is not input under the prescribed conditions, the normal operation is engaged se ver al V
after a change in input operation under the prescribed conditions.
Note
: An image is superimposed when the next exposure ends before the previous image is output.
1: This is a signal input from the outside.
2: As shown in the table on page 7, exposure time Te is determined by the setting of a DIP switch.
3: The normal operation state is engaged when the high period exceeds 1/3 sec. After that, the external
trigger shutter operation is engaged when the trigger pulse goes “low”. In this case , the area betw een the
falling edge of a trigger pulse and the subsequent 50 ms period is an external input inhibition area. During
the trigger inhibit period, an input trigger may be missed.
4: An internal VD signal is output by setting the INT/EXT switch on the rear panel to INT.
*
5: An image is output when an internal VD signal f alls 10 ms or more after a trigger pulse rises (as shown by
*
2 and 3 in the figure). If the time (T in the figure) between the f alling edges of a trigger pulse and internal
VD signal is under 10 ms, an image is output when the internal VD signal or the ne xtinternal VD signal f alls
(as shown by 1 in the figure). In this case, an image is output when the next internal VD signal falls. An
image and WEN signal are always output together. For more details, refer to the WEN signal. (The f alling
edge of an internal VD signal is the same in phase as the beginning of an equalizing pulse in a SYNC V
area.)
Note
: An image is superimposed when the next exposure ends before the previous image is output.

1: This is a signal input from the outside. The trigger interval should be trigger pulse width + 1 field + 2H
period or more. The trigger interval shorter than described above cannot be ensured. If a trigger pulse is
not input under the prescribed conditions, the normal operation is ensured several V after a change in
input operation under the prescribed conditions.
