SW-D7000U, 9CH. COLOR VIDEO MULTIPLEXER14 JVC PROFESSIONAL, IMAGING PRODUCTSNOTE: Do not use locked type S-video cable.2.3 CAMERA INPUTSUse 75 ohm BNC connectors and video coaxial cable to connect to the camera input BNC socketson the back of your multiplexer.For each camera input, there are two BNC sockets, one for the camera input and one for the loopedcamera signal. If you connect to both BNC sockets your multiplexer automatically removes the 75-ohm termination. If using the loop-through facility, make sure that your ultimate connection point(e.g. A monitor or VCR) provides a 75-ohm termination at the end of the line. If you do not use theloop-through output the multiplexer will automatically terminate at the input BNC.Connect your 9 camera inputs. If you have less than 9 cameras, you can disable individual camerainputs in the menu system, see CAMERA ENABLE/DISABLE.2.4 VCR CONNECTIONSThis connection consists of a video and VEXT input (25 pin D-sub) connections. For an S-VHSVCR, use 4-pin mini-din S-VHS connectors.For a standard VCR use 75 ohm coaxial cable and BNC connectors.NOTE: Do not use locked type S-video cable.If you are using S-VHS, then for full benefit, you must also select S-VHS in the VCR SETUP menu.Although the VEXT connection is optional, it is a good way to simplify the operation of yourmultiplexer because it automatically synchronizes your VCR to your multiplexer. If using the VEXTinput, the SWITCH INPUT option must be used in the VCR SETUP menu.NOTE: Some time-lapse VCR’s do not transmit a VEXT signal in real time mode (2 hourNTSC/EIA). In these cases, if you are using the VEXT input, select the same recordingspeeds in both the Alarm Record Speed and Normal Record Speed menu settings in theRECORD OPTION in the MAIN MENU.B1 2 3 4 5 6 7 8 9RS-23 2-1 SVHSSVHS1 RS-485 212 VDCAlarm, Vext & Accessoryconnections, DB-25 RS-232C RS-485Monitor A outputscomposite, Y/CVCR inputscomposite, Y/CMonitor B outputcomposite VCR outputsY/C, composite12V DC power,center positiveCamera BNC inputs1-9 looping
