①IMAGE SENSOR FRONT FACE
・The light receiving face of the image sensor(Dirt, water or oil deposits on the image sensor will cause an unclear picture on
the monitor. Attach the lens cap to protect the lens and the CCD fromcontamination and damage.)※When using a DC Auto-Iris lens, adjustments to the iris level can be doneby changing the level in the OSD menu by use of the remote control(RC-01) included. Please refer to the User’s Manual.
8) When detailed settings are required or an adequate image is not
obtained, connect the remote control(RC-01) to ⑩OSD(On Screen
Display) CONNECTOR, then set the functions on the screen by⑪OPERATION BUTTON.
9) When controlling the RS-485, alarm output and infrared cut-filter
changer, connect to ⑦I/O CONNECTOR after wiring using the attachedcable. See the pin configuration as follows.

DC+12VThe wiring of the connector must be exact.
Be careful not to touch the other terminal while wiring.
Protect the wiring portion by using insulation tape afterwiring. If the above care and attention is not adhered to,damage to the WAT-233 and power adaptor may occur andmay also cause fire.

④• Avoid the striking of hard objects or dropping the WAT-233.

7) After following the procedure below and the picture is still out of focus, open
the iris fully and loosen ③FINE FOCUS ADJUSTMENT SCREWS with thehex. wrench and move the lens forwards until a clear picture is obtained.
Manual Lens

Before connecting the auto-iris lens, please make sure that the pin configurationis correct by confirming with the following table. If the configuration of your iris
connector is different from the following, the plug and pins will need to berewired.

Description of Parts4) Connect ⑥VIDEO OUT on the WAT-233 with the monitor, using a
coaxial cable with 75Ω impedance, such as an RG-59 or an RG-6/U.
If the monitor has an S-terminal, high resolution imaging is possible byconnecting with ⑧Y/C OUT.
※The ⑧Y/C OUT can be used together with the ⑥VIDEO OUT.
※Select a monitor with the same television system as the WAT-233 NTSC orPAL. A monitor with more than 700TV lines is recommended.
5) Insert the power plug of the power adaptor into ⑨POWER IN on theback panel of the WAT-233. Confirm that the power adaptor is not connectedto the power supply before insertion of the power plug into ⑨POWER IN.
6) Turn on the power to the WAT-233, monitor and all other alliedequipment. When a picture cannot be obtained on the monitor, or a problem
occurs, check and follow the procedure mentioned in the【Problems andTrouble Shooting】section.

⑩OSD(On Screen Display) CONNECTOR
・The terminal designed for connection with the remote control for setting
the functions on the screen.

Auto-iris Lens

• Use a stabilized power adaptor designed for DC+12V±10%,

The WAT-233 uses high quality electrical parts and precisioncomponents.
• Do not connect any power supply directly to the video out
terminal of the unit.
Do not connect the WAT-233 with any monitor using a video/power
single transmission terminal. The WAT-233 is not designed for use
with this type of equipment. We also advise you to read theoperation manual of the monitor you plan to use before any
connections are made.
• Do not install the WAT-233 in a position subject to direct
sunlight.
Sunlight shinning directly onto the WAT-233 lens can cause
damage to the CCD.
• Select a stable place for installation of the WAT-233.
Use a support of durable strength around an installation position
on a ceiling or wall when a camera stand or tripod is used.
• Do not move the WAT-233 with the cables connected.
Before moving the WAT-233, always remove the video cable andpower cable from the rear of the camera first.
• Avoid using the WAT-233 near any strong electromagnetic field.
After installing into main equipment, if the WAT-233 is exposed toelectromagnetic waves causing the monitored image to become
distorted, we recommend the camera be shielded by appropriate
protective casing.

⑦I/O CONNECTOR
・The control terminal for the RS-485, ALARM and infrared cut filter changer.

WarningContents• Do not disassemble and/or modify the WAT-233.

with a current capacity of more than 250mA for the WAT-233.
The recommended voltage is DC+12V±10%• Do not expose the WAT-233 to wetness or high moisture
conditions.
The WAT-233 is designed and approved for indoor use only. TheWAT-233 is not water-resistant or waterproof. If the location of thecamera is outdoors or in an outdoor like environment, werecommend that you use an outdoor camera housing.
• Protect the WAT-233 from condensation.
Keep the WAT-233 dry at all times during storage and operation.
• Should the camera not work properly, switch off the powerimmediately. Then check the camera according to the “Problems
and Trouble shooting” section.

④AUTO-IRIS SOCKET・This socket is for the video/DC auto-iris lens cable connector.
(Video/DC: Auto selected by the camera)• An object becomes embedded or a quantity of liquid seeps into the camera
housing③Contact the distributor or dealer from which the WAT-233 was purchased.

The definitions of the symbols used in this operation manual are:

③FINE FOCUS ADJUSTMENT SCREWS・There are 3 hex. adjustment screws each placed at intervals of 120゜for fine
focusing of the lens.

1) Ensure that the power to the WAT-233 and the peripheral equipment isturned off before making any connections.
2) Remove the lens mount cap from the WAT-233 and attach the CSmount lens. Use the optional C-mount adaptor (34CMA-R) when a C-mountlens is used.
3) Connect the iris control cable to ④AUTO-IRIS SOCKET on the WAT233 when an auto-iris lens is being used.

■External DAY/NIGHT control terminal
When EXT mode DAY/NIGHT image setting is selected, the camera mode canbe changed from DAY to NIGHT (IR-cut filter removed) by an applied voltage of 3to 12V between the terminals A1 and B1 (current value: 1mA at 3V and 6mA at12V). By connecting a light sensor as indicated in the diagram below,
DAY/NIGHT modes can be controlled according to the lighting condition of themonitored object. Please make sure the electrical polarity is correct whenconnecting the cables.

■DAY/NIGHT status output terminal
When in NIGHT mode (IR-cut filter removed), the terminals A2 and B 2 are closed
circuit, therefore, the IR projector system is turned on if it is attached as thediagram indicated below. Please make sure that the attached IR projector
system supply voltage is 16V or less and the output current is 250mA or less.
