DPX16m: Instructions for Basic Operation and Installation
Page 6
3.
Determine the record speed (record hours format) you will use with your VCR and set up
the DPX16m to work with your VCR using the “VCR Set up” and “VCR Selection” menus
(see page 10).
4.
Exit the DPX16m menus by pressing the DISPLAY button to exit each menu and finally
the menu system.
5.
If your VCR has internal “on-screen” menus for its set up, use the “VCR Bypass” feature
of the DPX16m (see the “VCR Bypass Operation” description on page 8) to view the
VCR’s “on-screen” menus on the display monitor.
6.
At this point, the basic configuration of your DPX16m is complete. You may now proceed
to set more advanced functions as required for your installation (alarms, camera labels,
multiplexing options, etc.). Refer to the “Advanced Function Menus” starting on page 11
for detailed information for the feature(s) you require.

ONNECTIONS
The sixteen camera input BNC connectors each have a looping output and the factory default
configuration of each 75 Ohm termination is ON. Eight DIP switches inside the unit (see section below)
determine whether the termination is ON or OFF for each camera input.
The DPX16m has 75 ohm BNC video outputs for the main and call monitors. Connect a 75 ohm coax
cable between the “Main” monitor output and your primary monitor input. Connection of a separate
monitor to the “Call” monitor output is optional.
Connect a 75 ohm coax cable from the “VCR IN” BNC to the video output of the VCR and a 75 ohm coax
cable from the “VCR OUT” BNC to the video input of the VCR.
The two alarm connectors are a standard DB-15 type that will mate with the alarm wire adapter board or a
standard computer-type cable. See page 24 for further alarm connection information.

The top cover of the DPX16m should only be removed if it is necessary to adjust input termination
settings, or RS-232 port settings. To remove the top cover, remove the 4 screws on each side. Gently
slide the top cover back until the cover disengages from the plastic front panel bezel and then lift the cover
off the chassis. DO NOT ATTEMPT TO PULL THE COVER DIRECTLY UPWARD WITHOUT
DISENGAGING IT FROM THE FRONT BEZEL.

The video line termination switches for each camera input are accessed by removing the top cover. The
switches are located in pairs near the back panel on the main circuit board. Each switch pair is marked on
the circuit board and the 75 Ohm termination is enabled when the switch is in the “ON” position. The
factory default setting for each input is 75 Ohm termination “ON”. Also note that there is an additional
termination switch for the VCR input.
