Video Cable
1. It is recommended to use a video monitor whose
resolution is at least equal to the camera's.
2. Terminate the camera output with 75-ohm resistor
at the furthest end of its cable run.
A. It is recommended to use 75-ohms coaxial
cable.
(RG-59/U, RG-6/U, RG-11/U, RG-15/U)
B. Always set the last monitor`s termination
switch to 75 ohms, and set the termination
switches of intermediate monitors to high
impedance (Hi-Z) position.
C. The maximum extensible coaxial cable length
between the camera and the monitor is shown
in the table 1. Since cable quality varies
among manufactures, verify video quality
before final installation if maximum length are
to be used.

3. Wiring precautions :
• Do not bend coaxial cable into a curve whose
radius is smaller than 10 times the cables diame-
ter.
• Never staple the cable - not even with circular sta-
ples. Mismatching will occur.
• Never crush or pinch the cable
All of these will change the impedance of the
cable and cause poor picture quality.
Caution: Always set the Flange-back adjusting ring to
fully clockwise (C-mount side) by loosing the
screw on the ring before mounting the lens other-
wise the inner glass and CCD image sensor could
be damaged by the lens.
MOUNTING THE LENS
(1) Mount the lens by turning it clockwise onto the
lens mount of the camera.
(2) Connect the lens cable to the Auto Iris Lens
Connector on the camera when an auto iris lens is
used.
