Important:
Before setting up the camera for a configuration
where the camera's RS485 data port is used for
camera control (pan, tilt, etc.) by the system con-
troller, the camera's DIP switches must be con-
figured to specify the unit number and communi-
cation parameters. (This page)
If DIP switch setting is not performed, the system
controller control will not be possible and cam-
era setup will have to be performed again. Be
sure to check the DIP switch settings before set-
ting up the camera.
■ Heat radiation
The surface of the camera radiates heat. Ventilation
holes should be provided when installing the camera in
an enclosed ceiling or confined location where heat can
build up.
■ Beware of high humidity.
If the camera is installed when humidity is very high,
moisture may collect in the camera and cause the
dome to become foggy. If the dome becomes foggy,
remove it when the humidity is low and eliminate the
moisture inside the camera, and then replace the
dome. (page 9)

DIP SWITCH SETTINGS
In a configuration where the camera's RS485 data port is used for camera control (pan, tilt, etc.) by the system con-
troller, the camera's DIP switches must be configured to specify the unit number and communication parameters.
The camera mounting base needs to be removed to access the DIP switches. See steps 1 to 3 on page 16 for infor-
mation about how to remove the camera mounting base.
■ Communication Parameters (DIP Switch 2)
The factory default settings of these DIP switches are all OFF.
Switch 1: Terminator (Internal Termination Resistance)
Set it to ON in the following situations.
When only one camera is connected.
When only one camera is connected via a daisy chain over a long distance.
Switches 2 through 4: Communication Parameters
This setting toggles between 2-line and 4-line communication.
Use these switches to select the communication protocol being
used.
