CAMERA INPUTS
Use 75 ohm BNC connectors and video coaxial cable to connect to the camera input BNC sockets
on the back of your multiplexer.
For each camera input, there are two BNC sockets, one for the camera input and one for the looped
camera 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 the
loop-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 camera
inputs in the menu system, see CAMERA ENABLE/DISABLE.

VCR CONNECTIONS
This connection consists of a video and VEXT input (25 pin D-sub) connections.
VCR, 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 your
multiplexer because it automatically synchronizes your VCR to your multiplexer. If using the VEXT
input, 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 hour
NTSC/EIA). In these cases, if you are using the VEXT input, select the same recording
speeds in both the Alarm Record Speed and Normal Record Speed menu settings in the
RECORD OPTION in the MAIN MENU.
