It is necessary to adjust the communication speed and use
the same communication protocol with external devices
such as a controller when connecting those external
devices to the DATA port or the SERIAL connector
(RS232C).
It is also necessary to perform the settings for the network
such as the IP address and the gateway address when
operating this unit a PC via a network such as a LAN.
These are the descriptions of how to perform the required
settings for communication with external devices.

[Camera Control] Settings for the communi-
cation method and the cable compensation
for camera control

Select a communication method for each camera channel
to control cameras from the following.

COAX:

Controls camera with the coaxial communication

(CAM 1 - 8 CH are available for the WJ-HD316, CAM 1 -
6 CH are available for the WJ-HD309)

PSD:

Controls camera with the PS·Data. (CAM 9 - 16 CH

are available for the WJ-HD316, CAM 7 - 9 CH are
available for the WJ-HD309)

RS485:

Controls camera with the RS485 communication.

(CAM 1 - 16 CH are available for the WJ-HD316, CAM 1
- 9 CH are available for the WJ-HD309)

OFF:

Does not control camera (CAM 1 - 16 CH are avail-

able)

Notes:

• Perform settings according to the cameras connected

to this unit.

• CAM 9-16 control 4 cameras each (only for the WJ-

HD316).

• When using the coaxial communication to control cam-

eras, connect cameras to the VIDEO IN connectors 1 -
8 for the WJ-HD316 (1 - 6 for the WJ-HD309) (coaxial
communication compatible). When controlling cameras
connected to other VIDEO IN connectors with coaxial
communication, use a coaxial communication unit (WJ-
MP204). In this case, select "PSD" for the communica-
tion method for the camera channels to be controlled
through the coaxial communication unit.

• To prevent operation mistakes, set the unused camera

channels to off.
It is possible to compensate for the video signal trans-
mission loss from the camera when using the VIDEO IN
connector 1 - 8. (cable compensation)
Perform the settings for the cable compensation
according to the length of cable used.

When the length of cable used is shorter than 500 m

When the length of cable used is longer than 500 m

and shorter than 900 m

When the length of cable used is longer than 900 m

and shorter than 1 200 m

Notes:

• Use 5C-2V cables for the cable compensation.
• Perform the settings for the cable compensation prop-

erly according to the cable length. Otherwise camera
pictures may not be displayed/recorded correctly.

[PS.Data Setup] Settings for the PS·Data

Perform the following settings for the PS·Data.

Unit Address (System)

A unit address (System) is a unique number assigning to
PS·Data devices. The addresses must be unique to identify
system devices when connecting multiple devices compati-
ble with PS·Data. Numbers, "001"-"099", are to be assigned
as the unit addresses to the system devices.

Unit Address (Controller)

The unit address (controller) is used to control a PS·Data
device connected to this unit. Numbers, "001" - "099" are to
be assigned.

Cascade

Select ON or OFF whether or not to use the cascade con-
nection.
Set this to ON when connecting two or more units or in the
