PTZ CONNECTIONS
Four screw terminals provide connection to RS422 type Pan Tilt Zoom (PTZ) cameras. Two wires are for DO+
and DO-, and two wires are for DI+ and DI-. Shield may be used to keep the common mode voltage of the
camera and the DVMD14 transceivers within the +12 to -7V range. If Shield is used there will be ground loop
currents flowing and care must be taken to insure that the power supply of the camera can float (via isolated
transformer) with respect to the DVMD14 ground. DO+, DO- and Shield are used for most cameras, connecting
to their DI+, DI- and ground pins respectively. Shield is connected to DC common through a 100 ohm resistor for
all ports.
Pluggable Screw Connectors
The pin connections for the Pluggable connectors are shown in Table 1 below.

CONNECTION INSTRUCTIONS
Connecting the DVMD to a camera and computer is simple. The connections should be accomplished in the
sequence outlined below.
•
Step One:
Connect the 120/240 VAC Power Supply by attaching two IEC power cords to an AC outlet.
•
Step Two:
Connect a 75 ohm Coaxial Cable from the VIDEO OUT BNC connector located on the DVMD14 Rear
Panel (See Figure 3B) to the Video In port on a CCTV Monitor.
•
Step Three:
Connect a second 75 ohm Coaxial Cable from the VIDEO IN BNC connector on the DVMD14 to the
Video Out port on a camera.
•
Step Four:
Connect a CAT5 cable to the XPORT RJ45 interface and to a hub, router or Ethernet switch that is
connected to the HOST PC that is running ManagerNETxxx.
•
Step Four:
Power up both supplies on the DVMD14.
•
Step Five:
Determine the XPORT IP address. This may be set by the Lantronix XPORT configuration program
available from Radiant or Lantronix. Set the IP address to a value that is compatible with the LAN you
are using (E.G. 10.0.0.9, or 192.168.1.109). Set the port number as desired. (E.G. 4500)
•
Step Six:
Run ManagerNETxxx and enter a CAMERA value in the setup menu with the matching IP address and
port number from Step 5 above.
