Connect non-multiplex type cameras to the CAMERA IN
connectors 1 to 16. For cameras equipped with RS-485
communication facilities, connect the RS-485 cable as fol-
lows.
Check the camera addresses when using RS-485 cameras.
Operations from the system controller will be invalid if the
camera addresses are set improperly.
• Use addresses from 1 to 16 for individual cameras.
• Do not set the same address for more than one camera
in an RS-485 chain.
• Before connecting the RS-485 camera(s) to DATA 1, 2
and/or 3, configure the system through WJ-SX150A
Administrator Console.
■ Connection with the Camera
Sites
Connect the data-multiplex type cameras (or camera site
equipment) to the CAMERA IN connectors 1 to 16 on the
matrix switcher's rear panel.
Notes:
• Make sure that the cable length is less than 900 m
(3 000 ft) between the camera site and the unit when
using RG-59/U, BELDEN 9259 or equivalent cables.
• If you use locally procured cables, it is important to use
only a data-grade cable, which is suitable for RS-485
communication (shielded 2-wire twisted cable).
• When the cable length is extended, cable compensa-
tion is available. (Refer to pp. 74 and 94.)
