HR10A-10R-12PB-01 (Hirose) male
* Note : To change the signal output on pin no. 6, 7 and 9, it is necessary to make jumper setting.
See “7-2. Jumpers on board” for more informations.
CAUTION
1.
When trigger signal is input at #5 of 6 pin multi connector, do not input/ output HD signal at #6 of 12 pin multi
connector, as it causes a failure in Ext. trigger mode.
2.
Do not use video output at the same time both from #4 of 12 pin multi connector and BNC connector, as it
.
causes a failure on video signal due to double termination

6. Functions and operations
6-1. Input/ output of HD/ VD signal
a) Input of external HD/ VD signal (Factory pre-set)
To input ext. HD/ VD signal, make JP9/ JP11 short-circuited, and JP12/ JP13 open-circuited.
To change the termination of ext. HD/ VD signal, it is neccessary to make the jumper JP8/ JP10
short-circuited. All jumpers are located on PK8273 board. For details, please refer to 7-2-
3. Jumpers on PK8273 board.
Note : Factory pre-set is set at HD/ VD input (TTL) .
b) Output of internal HD/ VD signal
To output int. HD/ VD signal, make jumper JP9/ JP11 open-circuited, and JP12/ JP13 short-
circuited. All jumpers are located on PK8273 board. Please refer to 7-2-3. Jumpers on
PK8273 board.
CAUTION
Int. HD/ VD signal is effective only at 75 Ohm termination.
6-2. Ext. trigger/ readout mode
Ext. trigger mode of CV-M40 allows 3 different driving modes, as follows.
Edge pre-select trigger : Asynchronous reset by the external trigger pulse
mode
Exposure period controlled by 8-step fixed shutter steps
Pulse-width control
mode
: Asynchronous reset by the external trigger pulse
Exposure period controlled by the pulse width of the external trigger pulse.
Frame-delay readout
mode
:
Asynchronous reset by the external trigger pulse
Exposure period controlled by 8 fixed shutter steps
Video readout timing controlled by rising edge of the external trigger
pulse.
6-2-1. Edge pre-select mode
In this mode, the exposure starts at the falling edge of the external trigger pulse. The WEN
pulse originates from the camera.
The shutter speed is controlled by the SW1 switch on the rear panel of the camera and the RS
232C serial interface.
For details, refer to the timing charts section of this manual.
To use this mode, set up the camera as follows ;

CV-M40
a)
Set SW1-5 at ON, and SW1-6 at OFF to select the Edge pre-select mode.
b) Set SW1-1 to SW1-3 to select the appropriate shutter speed. For controlling the shutter
speed by the RS 232C serial interface, set SW1-8 at ON.
c)
Set the SW1-4 switch to ON to select the Binning mode and set the switch SW1-7 to OFF
to select the Partial scan mode.
CAUTION
The pulse width of the external trigger pulse must be 2H to 1300H.
6-2-2. Pulse width control mode
In this mode, the exposure time is controlled by the pulse width of external trigger pulse. The
exposure starts at the falling edge of the external trigger pulse and ends at the rising edge of
the external trigger pulse. The WEN pulse is generated and output from the camera.
For details, refer to the timing charts section of this manual.
To use this mode, set up the camera as follows ;
Set SW1-5 at OFF, and SW1-6 at ON to select the Pulse width control mode.
a)
b)
Set the SW1-4 switch to ON to select the Binning mode and set the switch SW1-7 to OFF
to select the Partial scan mode.
CAUTION
The pulse width of the external trigger pulse must be 2H to 525H.
6-2-3. Frame-delay readout mode
In this mode, the timing of the video output is controlled by the width of the external trigger
pulse. The exposure starts at the falling edge of the external trigger pulse and ends according
to the shutter setting. The video signal is output at the rising edge of the external trigger signal.
The WEN pulse is generated and output from the camera.
For details, refer to the timing charts section of this manual.
To use this mode, set up the camera as follows ;
Set SW1-5 at ON, and SW1-6 at ON to select the Frame-delay readout mode.
Set SW1-1 to SW1-3 to select the shutter speed.
a)
b)
c)
Set the SW1-4 switch to ON to select the Binning mode and set the switch SW1-7 to OFF
to select the Partial scan mode.
CAUTION
The minimum value of pulse width for the external trigger pulse depends on the exposure time, as follow.
Minimum : pulse width (more than 3H) > exposure time

Jumpers JP1 and JP2 are used to select the gamma setting. See table below for options.
Please note that both jumpers must be in the “open” position to allow RS 232C setting of
gamma. If no setting is provided via RS 232C, the camera will default to gamma 1.0.
Note : Gamma is set at “Setting by RS 232C interface” with 1.0.
CAUTION
Do not set the jumpers both JP1/ JP2 at short circuited, as it causes a serious damge to the camera.
7-2-2. Jumpers on PK8202 board
Jumpers JP5, JP6 and JP7 enable or disable the ext. trigger input, the WEN output and pixel
clock output, respectively.

a) Jumpers JP8 thru JP13 control the input/ output state as well as the termination of the HD
and VD signals on pin #6 and #7 of the 12 pin connector.
b) Jumpers JP14 thru JP17 control the effective number of lines in the partial scan mode.
Note : Partial scan is set at 120 (v) as factory pre-set.

c) JP22 WEN Polarity Reversing
When JP22 is set to OPEN, WEN is output, and only 1H period becomes HIGH level before
video output starts. The periods from WEN output and video start may differ at each mode.
When JP22 is set to SHORT, WEN’s image output period becomes LOW level, and after finish-
ing output, it becomes HIGH level.
The periods from WEN output and video start is same at each mode.

10. Appendix
10.1. Precautions
Personnel not trained in dealing with similar electronic devices should not service this camera.
The camera contains components sensitive to electrostatic discharge. The handling of these devices
should follow the requirements of electrostatic sensitive components.
Do not attempt to disassemble this camera.
Do not expose this camera to rain or moisture.
Do not face this camera towards the sun, extreme bright light or light reflecting objects.
Even when this camera is not in use, put the supplied lens cap on the lens mount.
Handle this camera with the maximum care.
Operate this camera only from the type of power source indicated on the camera.
Power off the camera during any modification such as changes of jumper and switch setting.
10.2. Typical CCD Characteristics
The following effects may be observed on the video monitor screen. They do not indicate any fault of the
CCD camera, but do associate with typical CCD characteristics.
V. Smear
Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical smear may
be visible on the video monitor screen. This phenomenon is related to the characteristics of the
Interline Transfer System employed in the CCD.
V. Aliasing
When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on the
monitor may appear.
Blemishes
Some pixel defects can occur, but this does not have en effect on the practical operation.
Patterned Noise
When the CCD camera captures a dark object at high temperature or is used for long time integration,
fixed pattern noise (shown as white dots) may appear on the video monitor screen.
