Watec WAT-902H Operation Manual

WAT-902H
CCD CAMERA
OPERATION MANUAL
INTRODUCTION:
Thank you for choosing the WAT-902H, B/W CCD Camera.
WATEC hopes that both the quality and design satisfy your requirements.
Before proceeding to install or operate the WAT-902H, please read and understand thoroughly the contents of this
Operation Manual.
For future reference we also advise safe keeping of this manual.
CAUTIONS:
1. Use only the AD-901 or equivalent power adaptor for the WAT-902H. Power supplied without voltage stabilization
and/or the voltage range is not maintained at ±10% 12VD. C. may cause damage to the WAT-902H.
2. Do not expose the WAT-902H to wetness or high moisture conditions. The WAT-902H is designed and approved
for indoor use only.
If the location of the WAT-902H is outdoors or in an outdoor like environment, we recommend that you use an
OUTDOOR CAMERA HOUSING.
3. Avoid the striking of hard objects or dropping the unit.
4. Do not disassemble and/or modify the WAT-902H or the component parts or accessories. WATEC can not be held
responsible for equipment failure or any damage or trouble caused by such action.
5. Do not install the WAT-902H near a heat source, such as radiators or heating air ducts, or in a position subject to
direct sunlight ※, excessive dust, mechanical vibration or shock.
6. When the WAT-902H is used under fluorescent or mercury lighting conditions, a flickering phenomenon may
occur on the monitor screen. This does not mean that the WAT-902H is damaged.
7. A white dot affected by cosmic rays may casually appear on the monitor screen. This is a characteristics which the
CCD cell unit has and is not considered abnormal.
8. When installing the WAT-902H 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.
9. Check and protect the WAT-902H from any source generating a strong electromagnetic field from your equipment,
when the WAT-902H is fitted near or inside that unit.
10. Do not connect any power supply directly to the VIDEO OUT terminal of the unit. This may cause damage.
11. 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 to the video signal terminal of the WAT-902H.
12. Do not make connections and/or operate the WAT-902H with wet hands.
13. Should the WAT-902H not work properly, switch off the power and then check that power and video terminals are
properly connected.
※ Sunlight shinning directly onto the camera lens can cause damage to the CCD.

DESCRIPTION OF CAMERA PARTS (Unit:mm)
(Front)
①CCD front face ②Lens mount(CS mount type) ③Hexagonal focusing adjustment screws(3pcs)
④Tripod mounting screw holes(Upper and lower) ⑤AUTO IRIS SOCKET ⑥VIDEO OUT
⑦SHUTTER switch ⑧POWER
①CCD front face (light receiving face of the CCD camera)
NOTE: 1. Handle the CCD and the 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 or oil deposits on either will cause an unclear picture on the monitor and scratches will
become permanent damage.
②Lens mount (CS mount type)
NOTE: Any standard model C mount lens can be attached to the WAT-902H, if our optional C mount ring,
30CMA-R is fitted to the unit.
③Hexagonal focusing adjustment screws (for fine focusing adjustment by the lens mount ring.)
There are three hexagonal focusing adjustment screws each placed at intervals of 120°around the lens mount
ring for the forward and backward motions of the lens mount.
④Tripod mounting screw holes (Upper and lower)
Thread size and depth are the same as those for the standard camera tripods.(U1/4")
⑤AUTO IRIS SOCKET
Female connector for the auto-iris lens.
NOTE: When the BLC(back light compensation)switch is ON in conjunction with the auto iris lens, the iris
control is shown within the restricted area on the monitor screen. See Sec. 9 of OPERATION in the
operation manual for a more detailed explanation.
⑥VIDEO OUT-The RCA terminal for video signal output.
Iris connector
NOTE: A 3C2V or 5C2V cable with 75Ω impedance must be used for connection with the WAT-902H.
(Side) (Rear)
When conversion of the AGC Lo/Hi⑨
switch is required, loosen the four corner
screws on the rear panel and pick them up
with tweezers.
Slide the ⑨switch towards your required
⑨AGC Lo/Hi
position with the tweezers and make sure to
position it firmly. Otherwise it may cause
instability to the WAT-902H.
NOTE 1. Be careful not to scratch the surface
of the rear panel during this
conversion work.
2. Do not bear any excess force to the
⑨switch on conversion. THIS
MAY CAUSE DAMAGE.
⑦SHUTTER switch-The electronic shutter speed conversion switch

ON EIA: 1/60~1/100000 CCIR: 1/50~1/100000
OFF EIA: 1/60 CCIR: 1/50
⑧POWER-The power input terminal
NOTE: The optional power adaptor, AD-901 (DC+12V, 250mA) is recommended for use with the WAT-902H.
⑨AGC Lo/Hi-AGC gain switch
The switch is set to Hi gain at the upper position and to Lo gain at the lower position.
The switch is set to Hi upon shipment.
OPERETION:
NOTE: Ensure that before any connections are made to the WAT-902H the power is switched OFF.
1) Remove the Lens Cap from ① the CCD front face and attach the lens.
NOTE: When the C mount type lens is used, mount the optional 30CMA-R, C mount conversion ring before the
lens is mounted.
: Confirm the specifications of the lens to be used, when it can not be mounted onto the WAT-902H smoothly.
(Mounting a non standardized lens may cause damage to the threads of the lens and lens mount too.)
2) Using the Auto Iris lens
Connect the iris control cable to AUTO IRIS SOCKET⑤ on the WAT-902H, when the auto iris lens is used.
IMPORTANT NOTES FOR AUTO IRIS USAGE
: Ensure that the connector mentioned in the operation manual of the Auto-Iris lens
can be applied to the one shown in the diagram on the right connect it firmly to
the connector on the right side of the WAT-902H.
: Insert the pins as shown in the picture on the right. If the pin configuration is
different from that shown, use the special adaptor supplied with this unit.
CAUTION: Do not touch the power pin or the signal control pin with the Common
(GND) pins on the extra connector for the Auto Iris lens.
:The power (pin) in the drawing on the right must be used for connection
with the auto iris lens only, otherwise this may cause damage to the WAT-902H.
3) Insert the DC plug of the power adaptor to POWER⑧ on the rear panel of the WAT-902H.
NOTE: Ensure that the power adaptor is not ON before insertion of the DC plug into POWER⑧.
IMPORTANT NOTES FOR POWER ADAPTOR USAGE
: Use a stabilized power adaptor designed for DC+12V±10% with a current
capacity of 250mA.
: Use the optional DC plug when the shape or polarity of the DC plug of the DC
power adaptor can not be fitted to POWER⑧ on the WAT-902H.
: Connect the cables to the DC adaptor using the drawing on the right.
CAUTION : Be careful not to touch any other terminal while wiring.
NOTE : This may cause damage to the WAT-902H and power adaptor or may cause
fire if the above care and attention is not adhered to.
4) Connect VIDEO OUT⑥ on the WAT-902H to the monitor, using the coaxial cable with 75Ωimpedance such as
3C2V or 5C2V.
IMPORTANT NOTES ON THE MONITOR SPECIFICATIONS
: Select a monitor with the same transmission mode as the WAT-902H.
There are two versions, EIA and CCIR.
: A monitor with 700TV lines is recommended.
Caution: Do not use a monitor which uses a video signal/power multiplex transmission cable.
