Wiring Precautions
• Do not bend the coaxial into a curve with a radius smaller
than 10 times the cable’s diameter.
• Never staple the cable even if using circular staples.
Impendance mismatching will occur.
• Never crush or pinch the cable. This may cause poor
picture quality.
Connecting the RS485 Cable
Refer to the pin assignment (Figure 4) to make the correct
connection to the terminal for remote control by EIA/TIA RS485
format. Those cables should be 0.654 conductor twisted pair
cables. When using these cables the maximum extension
distance is 1000 m.
If this camera is the last camera in the network, the termination
resistor (see Figure 3) should be switched to ON.

Connecting LAMP Contact
To prevent mechanized OLPF (Optical Low Pass Filter)
hunting, this camera is equipped with LAMP and GND external
contact terminals (see Figure 4). When LAMP is connected to
GND, the camera is in B/W mode. When it is open, the camera
will automatically switch between B/W and color.
Caution When using IR illuminators, use a lens that is
compatible with IR illuminations. Any lens other
than a compatible one can result in the camera
being out of focus.
