38■ Connections for RS-485 Type CameraThere are two options to connect the camera with the matrixswitcher, depending on the distance between them.One is "Home Run" wiring and the other is daisy chainwiring. "Home Run" wiring has the transmission stability withless transmission loss, and daisy chain wiring has connec-tion flexibility with less data ports occupied. For data-multi-plex type cameras, 900 meters (3 000 ft) is the limit to usecoaxial cable such as RG-59/U, BELDEN 9259 or equiva-lent.Note: If more distance is required, use cameras andmatrix switcher with RS-485 communication feature.Remote control becomes possible.● "Home Run" Wiring1. Connect with a RS-485 camera in "Home Run" wiring asshown in the figure.2. Set the LINE SELECT switch to 2 or 4.Notes:• Before connecting RS-485 cameras to DATA1 to 3, dataport setting through WJ-SX150 Administrator Console isnecessary. (Refer to p. 81 Data Port.)• Recommended for RS-485 communication is AWG#22or thicker one. The cable should be shielded, two-wire,twisted pair, and with low impedance.• Set the LINE SELECT switch to 4 when programmingpreset position of WV-CSR600/650 Series camera isconnected to the unit.● Daisy Chain Wiring1. Draw up a plan for connection between the camerasand the input channels of the matrix switcher, and theassignment of unit addresses to cameras.2. Set the LINE SELECT switch to 2. Also, set the connect-ed device's switch if required.3. Connect one end of the cable to RS-485 (CAMERA),and the other end to the first camera in the chain, asshown in the figure. Repeat this procedure for all cam-eras.4. Set the termination switches of the cameras at the chainends to ON. Camera's termination switches must be setto OFF except the ones at the chain ends.Notes:• Set the same number for the camera's unit address asand CAMERA IN.• Check the settings of the camera addresses whenusing RS-485 cameras. Operations from the systemcontroller will be invalid if the camera addresses are setimproperly.• Do not use addresses other than 1 to 16 for individualcameras (More than 17 cameras are not allowed).• Do not set the same address for more than one camerain an RS-485 chain.• Termination is the key to data transmission and recep-tion in the chain. While the other switches are set toOFF, only the switches at the chain ends must be set toON.• The termination of this unit's RS-485 camera port isalways set to ON. Connect the unit at the end of thedaisy chain.• The more equipment there is in the chain, the slowerthe response may be.WJ-SX150RS-485 type camera2DATA 3 DATA 2TERMOFF ON 4RS485(CAMERA)LINESELECTRS485(CAMERA)DATA 4PS•DATADATA HDR DATA 1Set it toposition 4.WV-CPR450 and others (For theTermination Switch positions, referto the oprating instractions of thecamera.)(A)(B)GNDOFF ONWJ-SX1502DATA 3 DATA 2TERMOFF ON 4RS485(CAMERA)LINESELECTRS485(CAMERA)DATA 4 DATA 1Set it toposition 2.DATA HDRPS•DATARBRATBTAGNDNoneMatrix switcher's rear panelTBTARBRARS485 Port
