7.3. Camera Control Cable Connection
• Connect camera control terminals "+" and "-" (RS-485) of the Remote Controller or the Interface Unit to the
camera's camera control terminals "+" and "-", respectively.
• Sequentially connect the camera's camera control terminals "+" and "-" to the next camera's camera control
terminals "+" and "-."
• Connect the GND cable in the figure below to the Camera Input/Output Connector Terminal No. 5, GND
terminal (white cable).
Notes
• The maximum number of units connectable to a pair of RS-485 lines (from termination to termination) is 32
units including the Remote Controller. The maximum cable length connecting each terminal is 1.2 km in
total.
• The camera may not operate correctly if 32 or more units are connected or the total cable distance exceeds
1.2 km. In such cases, split or extend wiring using the C-IF500 Interface Unit.

7.2. Note on Camera Installation
• Be sure to seal and insulate each connection of the video output cable, power supply cable, control cable,
and alarm cable with each corresponding cable from the other equipment using the waterproof tape. Perform
the wiring paying attention not to touch the peripheral metal parts.
Monitor, Digital video recorder
Remote controller
AC adapter
Insulate each cable with the waterproof tape.
• Avoid installing the camera cables in close proximity to fluorescent lamps or other electrical appliances.
Failure to do this can downgrade the picture quality.
• If there is a strong electric or magnetic field near the camera, such as television transmission antennas,
motors or transformers, this may distort or roll the monitor picture. In such cases, run the entire wiring route
through metal conduit tubing.
• Before applying the power to the camera, be sure to complete all connections between the camera and
related equipment.
