Initial Installation and Configuration
Before installing the VPort 251, verify that all items in the package checklist
are present. In addition, you will need a notebook or PC equipped with an
Ethernet port to complete the installation.
Step 1: Connect the power source, and connect loop-through power output
if required.
The VPort 251 can be powered by a 12 to 32 VDC power source, or an 18 to
30 VAC power source. The power input jack accepts a concentric barrel-type
connector. The loop-through power output accepts a 2-pin terminal block
connector. Check the STAT LED on the top panel to verify that power is
connected correctly.
NOTE The VPort 251's power output is looped through the power input
and will match the voltage of the power input source. For example,
if the power input is 12 VDC, the loop-through power output will
also be 12 VDC.
Step 2: Connect the VPort to the network.
The VPort 251 has an auto-sensing 10/100 Mbps Ethernet port, with built-in
LEDs to show 10 Mbps (amber) or 100 Mbps (green) connection activity.
Step 3: Connect the VPort to a camera and an audio source.
Use a coaxial cable to connect a video camera to the VPort's VIDEO INPUT
port, which uses a BNC connector.
A microphone or an amplifier can be plugged directly into the VPort's AUDIO
INPUT jack, and a speaker can be plugged into the AUDIO OUTPUT jack.
NOTE Check the VIDEO LED on the top panel to verify that the video
connection is working properly.
Step 4: Connect the VPort 251 to a motorized PTZ camera/device.
If you are using a PTZ camera or device, you can connect the PTZ control
cable to the VPort to allow PTZ control over the network. A 5-pin terminal
block for RS-232/422/485 serial connections is provided for this purpose. The
pin assignments are shown below:
PIN RS-422/485 RS-232
1 GND
Ground GND Ground
2 R- Rx- --- N/A
3 R+ Rx+ RxD RxD
4 T-\D-
Tx-/ Data- --- N/A
5 T+\D+
Tx+/ Data+ TxD TxD
To enable PTZ control, configure the PTZ control protocol in the VPort's
web-based manager.

NOTE Drivers are required to support specific PTZ control protocols. The
VPort 251 supports the following protocols:
yPelco D
yPelco P
yDynaColor DynaDome
For other protocols, please contact the video camera manufacturer
for the PTZ control commands. You may then use the VPort 251’s
Custom Camera function to program PTZ control.
NOTE New PTZ drivers can be uploaded for the VPort 251. Please contact
a Moxa sales rep to discuss development of new PTZ drivers.
NOTE The “Transparent PTZ Control” function can be used for PTZ
camera control over the network, without requiring special PTZ
drivers. PTZ cameras can be directly controlled by a keyboard or
PTZ control panel on the network.
Step 5: Configure the VPort’s IP address.
After powering on the VPort 251, wait a few seconds for the POST (Power On
Self Test). The STAT LED will turn green when the POST is completed. The
NETWORK LED will blink as the IP address is assigned. The IP address will
be selected according to the network environment.
Network Environment with DHCP Server
In this case, the VPort's IP address is assigned by a DHCP server. Use the
DHCP server’s IP address table or Moxa's VPort utility to look up the IP
address that was assigned to the VPort.
Using VPort and EtherDevice Configurator
1. Run edscfgui.exe to start VPort and EtherDevice Configurator. Select
Broadcast Search from the List Server menu to search for the VPort on
the network.
NOTE VPort and Ether Device Configurator can be downloaded at
www.moxa.com.
2. The Broadcast Search window will show a list of all EDS switches and
VPorts located on the network.
- 6 -

3. When the search is complete, every EDS switch and VPort found on the
network will be listed onscreen.
NOTE Broadcast Search can only search for devices connected to the
same LAN domain as the PC running the utility. If your devices are
located on different LAN domain, use the Specify IP Address
function to search for a specific IP address.
4. Double-click the selected VPort, or use a web browser to access the
VPort’s web-based manager (web console).
Network Environment without DHCP Server
If your VPort is connected to a network that does not have a DHCP server, then
you will need to configure the VPort's IP address manually. The default IP
address of the VPort 251 is 192.168.127.100 and the default subnet mask is
255.255.255.0. Make sure that you change your computer’s IP address and
subnet mask so that the computer is on the same subnet as the VPort.
Open the VPort’s web-based manager (see Step 6) and navigate to the System
Configuration ÆNetwork ÆGeneral page. Select Use fixed IP address to
ensure that the IP address you assign is not deleted each time the VPort is
restarted.
Step 6: Open the VPort's web-based manager
In a web browser, enter the VPort's IP address as the URL to open the VPort's
web-based manager.
Step 7: Install the ActiveX Control plug-in
When you first access the VPort’s web-based manager, a message will appear
regarding the installation of the VPort ActiveX Control component. Click
"Yes" to allow the display of video images in the web browser.
- 7 -

NOTE For Windows XP SP2 or above, the ActiveX Control component
may be automatically blocked for security reasons. In this case, the
warning message may not appear. Unblock the ActiveX control
function or disable the security configuration to allow installation
of the VPort ActiveX Control component.
Step 8: Continue to the VPort’s web-based manager
After installing the ActiveX Control component, the VPort’s web-based
manager will appear. Check the following items to verify that the system was
installed properly:
yVideo images
yAudio (make sure your PC’s or notebook’s sound is turned on)
yVideo information
Step 9: Access the VPort’s system configuration
In the VPort's web-based manager, the model name, server Name, IP address,
MAC address, firmware version, and LED status will be displayed at the top
of the page. Use this information to verify system information and installation.
Click System Configuration to see an overview of the system configuration.

Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing or wiring
the VPort.
Determine the maximum current for each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowed for each wire size.
If the current exceeds the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.
- 10 -

You should also pay attention to the following:
yUse separate paths to route wiring for power and devices. If power wiring
and device wiring paths must cross, make sure the wires are perpendicular
at the intersection point.
NOTE: Do not run signal or communications wiring and power wiring in
the same wire conduit. To avoid interference, wires with different signal
characteristics should be routed separately.
yYou can use the type of signal transmitted through a wire to determine
which wires should be kept separate. The rule of thumb is that wiring that
shares similar electrical characteristics can be bundled together.
yKeep input wiring and output wiring separated.
yIt is strongly advised that you label wiring to all devices in the system when
necessary.
Grounding the VPort 251
Grounding and wire routing help limit the effects of noise from
electromagnetic interference (EMI). Before connecting devices, run the ground
connection from the grounding point on the VPort to the grounding surface.
ATTENTION
This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
Wiring the Relay Output
The VPort 251 has one set of
relay outputs, labeled RELAY. 3
contacts on the 5-pin terminal
block on the VPort's top panel are
used for the relay output.
The relay output can be used for the following:
ySystem alarm, such as for network disconnection
yEvent alarm, such as for VMD (video motion detection), video loss, or
digital inputs
The maximum current and power capacity of the relay output is 24
VDC @ 1A. Please be careful not to exceed this power
specification.
Before connecting the VPort to the DC/AC power inputs, make
sure that the DC power source voltage is stable.
Wiring the Digital Inputs
The VPort 251 has one digital input channel, labeled DI. Two contacts on the
5-pin terminal block on the VPort's top panel are used to connect to this DI.
- 11 -

STEP 1: Insert the negative
(ground)/positive DI wires into the
┴/I1 terminals.
STEP 2: To keep the DI wires from
pulling loose, use a small flathead
screwdriver to tighten the
connection.
STEP 3: Insert the terminal block
connector into the receptor on the
VPort’s top panel.
Communication Connections
The VPort 251 has an RS-232 console port and a 10/100BaseT(X) Ethernet
port, which both use RJ45 connectors.
RS-232 Connection
The RS-232 console port is on the top panel and uses a 10-pin RJ45 connector.
Use an RJ45-to-DB9 or RJ45-to-DB25 cable to connect your PC COM port to
the console port. Cable wiring diagrams are shown below. You may then use a
console terminal program, such as Moxa's PComm Terminal Emulator, to open
the VPort’s console configuration utility.
