Connecting Devices to the DX4000
Use the following diagram of the rear panel of the DX4000 to determine how to connect devices to the unit.
Figure 5. Rear Panel of the DX4000
1. Connect up to four cameras at the video inputs. Refer to Table A for video coaxial cable distances. The DX4000 features automatic
termination of video if no loop out cables are attached. Remove all unused cables from the video output ports.
2. If desired, connect analog monitors to the video outputs (looping). Refer to Table A for video coaxial cable distances. You must terminate all
monitors. If you connect a single monitor to an output, terminate the monitor at 75 ohms. If you connect more than one monitor to an
output, terminate the farthest monitor at 75 ohms, and terminate the others at Hi-Z. Remove all unused cables.
3. If desired, connect an analog monitor to the main monitor output. Refer to Table A for video coaxial cable distances. If you connect more
than one monitor to an output, terminate the farthest monitor at 75 ohms, and terminate the others at Hi-Z.
4. If desired, connect a spot monitor to the DX4000. Refer to Table A for video coaxial cable distances. If you connect more than one monitor
to an output, terminate the farthest monitor at 75 ohms, and terminate the others at Hi-Z. Note that you can view live video from a spot
monitor. To search for and play back video or to configure the DX4000, you must be working at the unit and main monitor or at a remote
computer.
5. Select the video stream type for the cameras. Choices are NTSC or PAL.
WARNING: To avoid electric shock, turn off the unit and unplug it while connecting devices to the DX4000. Adequate ventilation is
required for proper operation of the DX4000. Allow two inches of space above the unit and on each side for air circulation.
Table A. Video Coaxial Cable Requirements
Cable Type* Maximum Distance
RG59/U 750 ft (229 m)
RG6/U 1,000 ft (305 m)
RG11/U 1,500 ft (457 m)
*Cable requirements:
75 ohms impedance
All-copper center conductor
All-copper braided shield with 95% braid coverage
WARNING: Changing the video stream type from NTSC to PAL reformats the hard disk. Do not change video stream types until any
recorded video has been backed up to CD or a removable USB flash memory device.
