1. Camera Mounting Screw Hole
This threaded hole (1/4” - 20) is used to mount the
camera onto a mounting bracket or tripod.
2. Flange-back Adjusting Ring
This is used to adjust the back focal length or pic-
ture focus by rotating this ring to clockwise for C-
mount lens or counterclockwise for special C-
mount (CS mount) lens.
CAUTIONS :
1. Always set this ring to fully clockwise before
mounting the lens to prevent damage of inner
glass or CCD image sensor.
2. Do not turn this ring too much to counterclock-
wise when the C-mount lens is mounted as
this could damage the inner glass or CCD
image sensor.
3. Lens (Option)
4. 12 V In Terminal (DC 12V IN)
This terminal accepts 12 V DC power source
(10.8V - 16V)
-5-
5. AGC ON/OFF Switch (AGC ON/OFF)
This switch is used to select the gain of the video
amplifier as follows :
ON: When the lens iris is fully opened at low light
shooting, a clear picture is obtained by auto-
matic increase of the gain.
OFF: A natural and low-noise picture is obtained
under a low light condition.
6. Automatic Light Control/Electronic Light
Control Selection Switch (ELC / ALC)
This switch is used to select the lens as follows.
ALC: Choose this position when using an auto iris
lens.
ELC: Choose this position when using a fixed or
manual iris lens.
7. Detail Level Selection Switch (SOFT/SHARP)
The detail/aperture level can be selected by this
switch. Set this switch to the desired position while
observing the picture on the monitor.
Note: The aperture is cut off at SOFT position.
-6-
8. Back Light Compensation On/Off Switch (BLC
ON/OFF)
When back light affects the picture, set this switch
to the ON position for a clear picture.
9. Automatic Tracing White Balance Control
On/Off Switch (ATW, ON/OFF(AWC))
The white balance setting can be selected as ;
ON: The white balance is automatically and con-
tinuously set by detecting the characteristic /
colour temperature of light source through the
lens and controlling the gain of red and blue
signal even if the characteristic / colour tem-
perature varies.
Note: The white balance setting is effected by the
setting level of the ATW Control (11). (The
bluish white is obtained when the ATW Control
has been set to the B side.
OFF: The white balance is automatically set and
fixed with the condition switched to the AWC
from ATW. When the characteristic/colour
temperature of light source changes, set this
switch to the ATW ON position then set it back
OFF.
Note: The white balance setting is effected by the
setting level of the ATW Control (11). (The
bluish white is obtained when the ATW Control
has been set to the B side.
10. Power Indicator (POWER)
11. ATW Control (ATW ON, R/B)
This control adjusts the level of red and blue
colour balance even if the ATW ON/OFF Switch (9)
is set to any position. It is preset at the centre posi-
tion which usually provides accurate colour repro-
duction.
12. Video Level Control (VIDEO LEVEL, L/H)
This control adjusts the level of auto iris control
when the ELC/ALC Selection switch (6) is set to
the ALC position, or the level of electric light con-
trol when the selection switch (6) is set to the ELC
position.
Note: This control does not work in the following
conditions
• AGC ON/OFF Switch (5) is set to OFF with the
manual or fixed lens.
• AGC gain reaches the maximum level when
setting the AGC ON/OFF Switch (5) to ON.
13. S-Video Output Connector (S-VIDEO OUT)
The luminance (Y) and chroma (C) signals for
monitor are provided at this connector.
14. Video Output Connector (VIDEO OUT)
A 1.0 Vp-p / 75 ohms composite video signal is
provided at this connector.
