Video Input Connections
The DLM-7 Module uses NTSC or PAL compatible cameras. Use
only a CCIR camera, as older types may not function properly with
the DLM-7 Module.
Install the camera mounting hardware as per the manufacturer’s
instructions and mount the camera. Connect the camera to a
monitor, and align the camera with the target area and adjust the
camera’sfocus. Ifanon-sitemonitoristobepermanentlyconnected
betweenthecameraandtheDLM-7module,themonitorconnection
must be high impedance.
Connect the first camera to the VIN1 terminal and remove the
jumper clip from J102. If only one camera is used with the DLM-7,
it should be connected to input VIN1. Connect additional cameras
to BNC connectors VIN2 through VIN7. Up to seven cameras may
be connected to the DLM-7.
Power Requirements
The DLM-7 Camera Selector usually does not require an additional
power supply.
Connection to the DLM-1 Module
Ensure power is removed from all components before making
connections between the Downlook modules. Connect the DLM-7
ModuletotheDLM-1Module withthe10-pinribboncablesupplied.
Refer to the connection diagram below and ensure that the ribbon
cable is oriented properly.
Jumpers J102 through J108
Jumpers J102 through J108 are used to terminate unused video
inputs. If a video input is not used, short the pins for the terminal
using one of the supplied jumper clips. If a camera is connected
to a terminal, remove the clip from the jumper.
Local Video Output
A monitor may be connected to the DLM-7 to allow for local video
monitoring. The monitor will display the image from the currently
active camera. Connect a monitor with a high input impedence to
the VIDEO OUT terminal. If required, picture quality at the local
monitor may be adjusted with part R129. Use a small screwdriver
to adjust part R129; do not force the adjustment screw beyond its
natural range of motion.
