8 Rear View@1 Camera Input Connector 1-4 (CAMERA IN 1 2 3 4)These connectors accept the composite video signalsupplied by the cameras while passing through thecontrol data and VD2 sync signal.@2 Camera Output Connector 1-4 (CAMERA OUT 1 2 34)These connectors supply the looped through compositevideo of the camera image. Any one of these connec-tors can accept VD2 sync from a connected devicesuch as a Video Multiplexer that accepts compositevideo while sending VD2. Refer to page 23 for details.@3 Spot Input Connector (SPOT IN)Accepts a spot output signal supplied from anotherData Multiplex Unit when connecting more than one unitin a daisy fashion.@4 Spot Output Connector (SPOT OUT)Supplies the composite video signal of the selectedcamera, alarm activated camera or WJ-MP204C setupmenus to display them on the monitor. This BNC is usu-ally connected with a monitor. In a multi-unit connec-tion this is connected with SPOT IN of the next unitunless the unit is at the tail end.@5 VS/VD Input Connector (VS/VD IN)Accepts C. Sync, VBS or VD sync input. The unit willfollow the sync input while supplying sync through theVS/VD OUT connector to other devices. Cameras willfollow VD2 sync supplied through the CAMERA IN con-nectors. You need to set up VS/VD INPUT in the SYS-TEM menu window when connecting. Refer to page 23for details.Note: Sync source should comply with the EIA RS-170standard. Do not input signals having a high jittercontent such as VCR playback signals.@6 VS/VD Output Connector (VS/VD OUT)Supplies a sync signal depending on the input to theVS/VD IN connector and setting of the MODE DIPswitch #1. Refer to page 15 and 23 for details.@7 Alarm/Remote Terminal (ALARM/REMOTE)Pins #6-9 are used in one out of four ways most suitableto your system requirements: alarm input, alarm output,remote input, and remote output. Input/output is speci-fied by the position of an internal connector whilealarm/remote is specified in the SYSTEM setup menu.Refer to page 16 and 26 for more details.@8 RS-485 Terminal (RS-485)These terminals are exclusively used for devices com-patible with “Camera Communication Protocol” such asthe WJ-SX350 Matrix Switcher and WJ-FS616C VideoMultiplexer. Through R (receive) and T (transmit) termi-nals, the unit exchanges communication data for cam-era control and other commands in 2-line half duplex or4-line full duplex mode.@9 Data Port (DATA)This port is exclusively used to communicate withdevices compatible with “PS • Data protocol” such asthe WJ-FS316/416 Video Multiplexer, Digital DiskRecorder and System Controller WV-CU360C. Usingthis port is incompatible with using RS-485 terminalabove.#0 DIP Switch (MODE)Data communication mode and sync setting are speci-fied with this switch.
