OPERATION MANUAL

DIGITAL CCD COLOR CAMERA

WAT-231S

INTRODUCTION:

Thank you for choosing our WAT-231S DIGITAL CCD COLOR Camera.

Watec hopes that both the quality and design satisfy your requirements.

Before proceeding to install or operate the WAT-231S, please read and understand thoroughly the contents 

of this Operation Manual.

For future reference we also advise safe keeping of this manual.

CAUTIONS:

CCD front face (light receiving face of the CCD camera)

NOTE:

1. Handle the CCD and lens with special care.

2. Always attach the lens cap so as to protect the lens and the CCD from contamination and damage.

3. Dirt, water and oil deposits on either will cause an unclear picture on the monitor, and scratches 

will become permanent damage.

CS lens mount

Any standard C-mount lens can be attached to the WAT-231S, when our optional C-mount ring 34CMA-R is

fitted to ②CS mount lens.

Hexagonal focusing adjustment screws (for fine focusing adjustment by the lens mounting ring).

There are three hexagonal focusing adjustment screws each placed at intervals of 120°around the lens

mount ring for the forward and backward motion of the lens mount.

AUTO IRIS

Power and control signals are supplied to the auto iris lens when the auto iris lens is used.

See Sec.2 of the operation manual for more detailed attention. (Patent pending)

LEVEL (for Auto iris lens)- Auto Iris volume level adjustment.

When using a DC driven iris lens the volume level of the Auto iris can be adjusted using this function.

Tripod mounting screw holes (upper and lower)

Thread size and depth are the same as those for standard camera tripods (U1/4").

WHITE BALANCE selector with four different manual presetting, AUTO (Auto trace) M.W.B. (Manual

Push-lock white balance) for (R) and (B), and P.W.B. (Push-lock white balance) buttons.

NOTE:

⑦WHITE BALANCE selector is set to AUTO upon shipment.

See Sec. 8.

The ⑦WHITE BALANCE selector is set at ⑧M.W.B. then press button (R) for adjustment, and then 

release when the required setting is obtained.

⑧- 2 (B) button is effective when the blue color temperature is more enhanced.

The ⑦WHITE BALANCE selector is set at ⑧M.W.B. then press button (B) for  adjustment and then

release when the required setting is obtained.

P.W.B. must be used in combination with (B) push button for automatic correction of the color temperature  

The ⑦WHITE BALANCE selector is set to ⑧P.W.B. then press button (B) for  adjustment, and release when

the required setting is obtained.

BACK LIGHT (ON/OFF) switch for the Back Light compensation function.

NOTE:

⑩BACK LIGHT (ON/OFF) switch is set to OFF upon shipment.

VIDEO OUT

The B.N.C. terminal for video signal output.

NOTE:

A RG-59B (RG-140/U) or RG-6A/U coaxial cable with 75

Ω

impedance must be used for connection

with the WAT-231S. See Sec.4.

Y/C OUT - This terminal is for Y/C signal output.

NOTE:

A RG-59B (RG-140/U) or RG-6A/U coaxial cable with 75

Ω

impedance must be used.

POWER

The terminal is designed for connection with a DC plug from an appropriate power adaptor.

NOTE:

The optional power adaptor AD-901 (DC+12V,250mA) is recommended for use with the WAT-231S. 

See Sec.3.

: In the upper position the Gamma correction is at about 0.45.

: The Gamma correction switch is set to ON upon shipment.

SHUTTER SPEED switch- Electronic shutter speed conversion switch.

: ⑮ is set to 8-EI:OFF upon shipment.

: ⑮ can be selected in accordance with your required application.

AUTO trace setting: The white balance is automatically adjusted on the monitor screen in

various lighting situations.

Daylight setting (Approx.6300K): The white balance is adjusted when sunlight is

illuminating the monitored area.

Fluorescent lamp setting 1. (Approx.5100K): The white balance is adjusted when fluorescent

lamps being used emit light close to the blue spectrum.

Fluorescent lamp setting 2. (Approx.4200K): The white balance is adjusted when fluorescent

lamps being used emit light close to the red spectrum.

Incandescent lamp setting (Approx.3200K): The white balance is adjusted when incandescent

lighting is illuminating the monitored area.

⑧Manual Push-lock white balance setting: M.W.B. for (R)-red and (B)-blue color

temperatures. The two push buttons can be independently operated to determine any

required red or blue color temperature in a range of between 2500K and 9500K.

⑨Push-lock white balance setting must be used in combination with (B): The white balance

is corrected in conditions when the above pre-set modes are ineffective due to extreme color

temperature situations.

WHITE BALANCE lock setting.

Any required color temperature set by P.W.B. or M.W.B. button is active until the power is

switched off.

※

Use only the AD-901 or equivalent power adaptor for the WAT-231S. Power supplied without voltage

stabilization and/or the voltage range not maintained at   ±10% 12V. DC. may cause damage to the camera.

Do not expose the WAT-231S to wetness or high moisture conditions. The WAT-231S is designed and

approved for indoor use only.

If the location of the camera is outdoors or in an outdoor like environment, we recommend that you use an

OUTDOOR CAMERA HOUSING.

Avoid the striking of hard objects or dropping the unit.

Do not disassemble and/or modify the WAT-231S or the component parts or accessories. Watec can not be

held responsible for equipment failure or any damage and/or trouble caused by such action.

Do not install the WAT-231S near heat sources, such as radiators or heating air ducts, or in a position

subject to direct sunlight ※, excessive dust, mechanical vibration or shock.

When installing the WAT-231S in an industrial or commercial environment (i. e. within equipment housing,

near other electronic device, etc.), make sure to avoid any strong electromagnetic field, otherwise the video

output may be distorted and monitor sharpness compromised.

Do not connect any power supply directly to the VIDEO OUT terminal of the unit. This may cause damage.

When a cable operation system, such as video/power multiplex transmission is being used, check the

specifications or requirements of your monitor for proper connection with the video signal terminal of the

camera.

Do not make connections and/or operate the WAT-231S with wet hands.

Should the WAT-231S not work properly, switch off the power and then, check that power and video

terminals are properly connected.

Sunlight shining directly onto the camera lens can cause damage to the CCD.

Using the contents figures below, check to make sure all parts are present before use.

NOTE: 

Ensure that before any connections are made to the WAT-231S the power is switched OFF.

SETTING UP AND OPERATION OF THE WAT-231S:

Remove the lens cap from the WAT-231S and attach the lens.  

Use the optional C-mount adaptor 34CMA-R, when the C-mount model lens is used.

NOTE:

Confirm the specifications of the lens to be used, when it can not be mounted onto the WAT-231S

smoothly.

Connect the iris control cable to ④AUTO IRIS on the WAT-231S, when the auto iris lens is used.

NOTE:

Confirm the version of the auto iris lens to be used, as shown below;

1) Video iris lens.

2) DC driven iris lens.

・1-FL : Flicker compensation.

: This function is used to reduce the flickering phenomena occurring on the monitor screen caused by

fluorescent and mercury lamps. (This function is effective when used with normal commercial

power supplies and is effective at 50Hz in NTSC and 60Hz when using PAL).

See Sec. 7 + 8.

・8-EI : OFF (Electronic Iris)

: The  ⑮SHUTTER SPEED can be controlled automatically, also the Iris can be corrected

electronically in accordance with the light intensity of the object. 

It is more beneficial used in combination with a fixed iris lens which can not be adjusted to the

received light intensity.

・9-EI : FL (Electronic Iris)

: This relieves flickering and color-rolling (periodical variation of color).

: It is also effective when a fixed iris lens with a large F value is used.

(It is available for commercial power frequency areas such as 50Hz in Ntsc/Eia and 60Hz in Pal/Ccir

versions.)
