WAT-910BD H/W MANUAL
This manual is to explain the hardware features of the WAT-910BD.
Description requiring electrical knowledge needed to properly use the camera is included in the contents of this
document.
Please read this document carefully, and use and/or install the camera after full understanding.
Under improper installation, it may cause serious damage to the connected equipment and the camera.
Please contact the distributor or dealer from which the WAT-910BD was purchased, if you do not understand the
installation, operation or safety instructions laid out in our manuals.
How to use the OSD(On-Screen Display) menu and setting each function, for more information, please refer to
"WAT-910BD OSD Manual" together. In addition, how to operate and install the camera, please refer
"WAT-910BD Operation Manual" together with this document.
Design and specifications are subject to change for improvement without notice.
Watec is not responsible for any inconvenience or damages to the video and monitoring recording
equipment caused by misuse, mis-operation or improper wiring of our equipment.
Technical information contained herein is for reference only and does not convey any license by any implication
or otherwise under any intellectual property right or other right of Watec or third parties.
Watec does not assume responsibility for any right infringements arising out of the use of this information.
WAT-910BD is an ultra-high sensitivity B/W board camera equipped with 1/2 " format CCD.
By adopting the latest high-sensitivity CCD and DSP with a variety of functions to the signal processing unit,
WAT-910BD realized various functions and higher performances.
* In addition to the automatic exposure control function, high speed shutter and the electronic iris,
WAT-910BD is equipped with low-speed shutter (multi-field integration) function for dark
field imaging. High-quality imaging is now possible by the combination of these functions without
the illumination of the object.
* By adopting the latest DSP to the video processing block, a variety of digital signal processing functions
such as noise reduction, dynamic range correction, white blemish correction and motion detection are
available.
* For setting each functions, you can use user-friendly OSD menu or SPI communication to directly set
the functions.
* Digital output (parallel output) terminal is equipped for the video output, in addition to the conventional
analog output
* Since WAT-910BD is small in size (42mm square) and lightweight (approx.40g)design, making it ideal for
building into a variety of applications.

WAT-910BD H/W MANUAL
4.1 POWER INPUT
(1) Input Voltage
Recommended supply voltage range and the absolute maximum ratings
are as follows.
Normally, We recommend to use WAT-910BD in "Supply Voltage Range(recommended) ".
Using in range of "Supply Voltage Range(Capable)", the camera may be NOT damaged.
In this case(especially lower voltage condition), please check followings.
*When shooting a significantly brighter object, blooming or smear increases might occur.
*When using VIDEO IRIS LENS, the lens iris does not open, or the iris opening and closing is slow.
In the case of using "supply voltage range(capable)", please adopt it after fully evaluation of proper
operation of the camera/system.
In case of using power supply voltage exceed the maximum rating, it will cause a serious damage to camera
and/or to other equipment connecting to the camera.
(2) Power Consumption
Power consumption by the camera is about 1.32W. (Supply voltage: DC +12V, current consumption: 110mA)
This value is Typical. (It has been measured under the following conditions)
*Measuring condition:
1) The camera function settings are all default.(equal values after running the OSD menu "RESET")
2) Using a manual iris lens, the lens iris is fully closed.
The power consumption of the camera and efficiency depend on the supply voltage.
Under the above conditions, the measurement values of the power consumption and current consumption
related to the supply voltage are shown in following table.
Please note the following points in the selection and design of the power supply used.
* When a auto iris lens (Video iris/ DC iris) is used, the power consumption will increase.
The increment of current consumption is related to lens specification.
* By the combination of the camera functions to be used, the current value will change.
Please select or design power supply of enough performance, in consideration of camera usage.

4.3 DC IRIS LENS CONTROL
This connector is used to connect a DC IRIS LENS.
When connecting the lens, be careful to wire after
confirming the pin assignments.
(1) Wiring to the lens
Pin assignments of JEITA standard iris connector
and J3 connector terminal have one-to-one
correspondence as following.
(2) Adjustment method of the lens iris
The lens iris is adjusted with next steps.
STEP1: Fix the shutter speed by using OSD menu.(SETUP->EXPOSURE->SHUTTER)
Recommended setting of SHUTTER is either OFF(EIA:1/60,CCIR:1/50) or FL(EIA:1/100,CCIR:1/120).
STEP2: Turn off "SENSE UP" function.
STEP3: Turn off "AGC" function.
Set "GAIN" to the minimum value (6dB) by using "MANUAL GAIN" menu.
STEP4: Return to the EXPOSURE menu, by adjusting the VR1, set the proper lens iris.
STEP5: If the adjustment of lens iris is correct, when AGC is switched to LOW from OFF, the video signal
will be a little brighter.
STEP5: When switching to AGC LOW from OFF, and the video screen is to be slightly

WAT-910BD H/W MANUAL
(1)Video Data Format
The WAT-910BD is a camera that conforms to the EIA/CCIR video format.
The Analog Video Output (Video Output Connector:J2) is a composite video output which conforms to the
EIA/CCIR standard, however, the digital video output does not fully comply with these standards.
The video format of the digital data output is in accordance with table 5.1-7.
(2)Data Format
The output digital data conforms to the ITU-R BT.656, however, the output data clock rate (DCK)
frequency is as shown in the figure below.
※Caution: Does not comply with the ITU-R BT.656 Standard DCK=27[MHz] output.
The Chroma Signal, Luminance Signal, Blanking Data, and TRC Data are output in sequence from the
Digital Output Connector (J6).
TRC Code, Chroma Signal, and Luminance Signal data format comply with the ITU-R BT.656 standards,
however, due to the difference in DCK frequency, the Blanking Data Number, Effective Data Number,
and Total Data Number do not comply with ITU-R BT.656(DCK=27MHz). The Figure below shows the output
data number for each.

(3)Output Timing for Digital Data
The effective image data is outputs the Luminance Data and Color Difference Data in Y/Cb/Cr=4:2:2 format.
(The output sequence is repeated in the Cb,Y,Cr,Y,… sequence)
Since the WAT-910BD is a monochrome camera, the Cb,Cr data are all 80[h].
The Horizontal Blanking Period (without TRC Code) is Cb,Cr=80[h], Y=10[h], repeated output.
The TRC Code, which is used to set the Efective Pixel Period, is output with every horizontal line.
The TRC Code complies with the ITU-R BT.656 standard, and output the 4 Byte Codes below.
ＳＡＶ： Start of Active Video [hex]
ＥＡＶ： End of Active Video [hex]
The 4th Byte of the TRC code (XX) is output according to the Figure below.
*NOTE: F=0 : during field 1 F=1 : during field 2
