Moxa VPort 351 Introduction
1-2
Overview
The VPort 351 is a full motion, 1-channel Industrial Video Encoder that uses the standard MJPEG/MPEG4
algorithm, and features DIN-Rail Mounting capability, 12/24 VDC and 24 VAC redundant power inputs, and
IP30 protection to meet the requirements of industrial environments. The VPort 351 can digitize any analog
video source and distribute these digital images over an IP network, turning your CCTV system into a “Video
over IP” Network System INSTANTLY. The cutting edge video compression algorithm gives the VPort 351 an
FPS of up to 30 in D1 resolution (720 x 480), with maximum bandwidth of 5 Mbps, to provide high video
performance and more efficient network transmission. In addition, the VPort 351 also provides 2-way audio
communication for a voice over IP communication, making the control of your video surveillance system more
real-time.
In addition, the VPort 351-T is rated to operate at temperatures ranging from -40 to 75°C, which is especially
suitable for outdoor applications.
High Performance MJPEG/MPEG4 compression
Video input can be efficiently compressed into MJPEG/MPEG4 video stream packets without delay. This is all
done without sacrificing remote monitoring capability or storage. Five levels of compression quality and four
different image resolutions are provided to provide greater versatility.
2-way audio supported for a complete surveillance solution
The VPort 351 supports both audio input and audio output for voice over IP communication between a field site
and central site. The 2-way audio function not only saves time, but also saves the cost of needing to add
additional communication devices (such as a phone).
Video recorded pre/post-alarm for better event records
The VPort 351 is designed to record pre/post alarm video to help system administrators determine what causes
an alarm to be triggered. The record includes both video and time stamp to provide a more complete record.
Rugged design for industrial environments
The VPort 351 is an industrial video encoder, which means that it is specially designed for harsh industrial
environments. With the 12/24 VDC and 24 VAC redundant power inputs, IP30 protection, and DIN-Rail
mounting, the VPort 351 meets the critical requirements of most industrial applications. Most importantly, the
VPort 351-T can operate reliably in a -40 to 75°C temperature range, making it the first video encoder of its
kind that can be used for extended temperature, industrial-grade applications. The VPort 351-T is an optimal
solution for outdoor environments. In addition, the VPort 351 has received important industrial and safety
approvals, such as UL508, Class 1, Div. 2, making the VPort 351 well suited for transportation, utility, and
manufacturing systems.
RTSP streaming for easy integration
RTSP (Real-time Streaming Protocol) is a client-server multimedia presentation control protocol, which enables
the interoperability of video devices and software. Hardware or software that supports RTSP streaming can
easily identify and decode the video stream without the hassle of codec installation. For example, users can
view video images from the VPort 351 directly with Quick Time and VLC, both of which support RTSP streaming.
Multicast (IGMP) transmission for network efficiency
Transmitting digital video images via an IP network requires a dozen times the bandwidth required for
transmitting general data. For this reason, the efficiency of network bandwidth management is one of the most
important issues that determines the performance of a video over IP surveillance system. The VPort 351
supports multicast transmission with IGMP protocol, which can reduce the bandwidth requirements when
multiple clients access the same video stream, and greatly increases the efficiency of network bandwidth
management.

Moxa VPort 351 Introduction
1-3
Easy web access using standard browsers
There is no need to install new software to access the video encoder, since the embedded web server allows
users to use any popular web browser to access the video encoder from anywhere over the Internet. As long
as you are connected to the network, you will be able to view the same images seen by your cameras.
Built-in 3 area-selectable Video Motion Detection (VMD)
External sensors are not required, since the video channel can be configured to detect motion in 3 areas,
making it easy to set up a security system in either your office or the field. And the customizable settings allow
you to tune the system for both object size and sensitivity, making the video encoder adaptable to different
environments.
Weekly schedule for automated surveillance
The user-defined time period will check security settings on a weekly basis, and send notifications or drive
external devices, making the VPort 351 suitable for more versatile applications.
Flexible I/O control for external devices
2 opto-isolated sensor inputs and 2 relay outputs are provided to control external devices, giving system
integrators the option of turning an analog system into an advanced security system.
Moxa SoftDVR Lite IP Surveillance Software
To extend the video encoder’s capabilities, Moxa SoftDVRTM Lite IP Surveillance Software, which supports a
maximum of 4 cameras in quad, is included free of charge, allowing users to turn their PC into a digital video
recorder. Scheduling or one-click recording saves important images on your local hard disk, and the reliable
motion detection and instant warning features make you ready for any situation. A quick and easy to use
search and playback function lets you easily find the image you’re looking for, so that you can inspect the
images more carefully, and also save the output to an AVI file.
SDK support for developers
The high-performance video encoder can be integrated into many applications—without busting your
budget—and the complete programming interface of the Moxa VPort SDK PLUS makes the developer’s job easy
and straightforward. To ask about SDK requirements, please contact a Moxa sales representative for details
and an application form.

Product Description
BNC video input/output
The BNC video input is a 75-ohm video port for connecting an external camera. To ensure that the correct video
modulation type is detected, cameras should be connected and powered on before the VPort is powered on.
NOTE
Please use the standard CCTV cable (RG59U or above) to connect the video camera and VPort’s BNC connector.
Mini stereo jacks for audio input/output
The VPort 351 has 2 mini stereo jacks for audio input and output on the front panel. One jack is for a
MIC-in/Line-in audio input connection, which can be directly connected with a microphone or an audio source
from an amplifier. The other jack is a Line-out audio output connection, which can be used to connect
earphones or an amplifier.
DIP switches for 75-ohm resistance and audio signal test
2 DIP switches are located between the video input and video output connectors.
VPort 351’s video output port is a loop-through port. If the user wants to use the video output port, the 75-ohm
dip switch (DIP switch 2) must be turned to OFF to enable this loop-through video signal. If the video output
port is not used, the 75 ohm dip switch needs to be turned to ON (the default is ON).
DIP switch 1 is for switching the audio input and audio output to the loop-through mode for testing the audio
source signal. Put the DIP switch in he ON position to activate the Audio Test mode. In this case, sound from
the microphone connected to the audio input jack can be heard through the speaker or earphones connected
to the audio output jack. In addition, if the audio test mode is enabled, you can check if the audio signal is
working by looking at the AUDIO TEST LED.
NOTE
Please make sure the 75 ohm DIP switch is turned to ON when only video input is used, or the video image
display may
be not stable.

To enable PTZ control, users should configure the PTZ control protocol in the web console.
NOTE
The PTZ control protocol is not standardized. To use a particular PTZ control protocol, the video encoder must
support the driver for that protocol. Currently, the VPort 351 supports PTZ control protocol drivers for:
1.
Pelco D
2.
Pelco P
3.
Dynacolor DynaDome
In addition, there is an item named “Transparent PTZ Control” in the camera driver list, which is used to
transmit the PTZ control signal through the TCP/IP network to the VPort D351 video decoder or PC (additional
Real COM driver required), and the PTZ co
ntrol panel or keyboard can directly control the PTZ camera or
device. In this way, there is no need for a PTZ camera driver and better than that, you are not limited because
you don’t have a particular protocol .
In addition, to using a protocol that is not on the list, you will need to contact the manufacturer of the camera
to get the PTZ control commands, and then use the VPort 351’s custom camera function to program the PTZ
control.
NOTE
The VPort 351 comes with a PTZ driver upload function for imple
menting new PTZ drivers. Please contact a
Moxa sales representative if you need assistance from Moxa’s R&D department to create a new PTZ driver.
Redundant 12/24 VDC and 24 VAC power inputs
The VPort 351 has two power inputs to provide redundancy. Each power input support both 12/24 VDC and 24
VAC power for greater versatility.
NOTE
The supported power input specifications for the VPort 351 series are 12
-
32 VDC for a 12/24 VDC power input,
or 18
-30 VAC for a 24 VAC power input. This differs from the Moxa EDS switch’s 12-45 VDC power input.

Moxa VPort 351 Introduction

The VPort 351 has one RS-232 (10-pin RJ45) console port located on the top panel. Use either an RJ45-to-DB9
cable or RJ45-to-DB25 cable to connect the VPort 351’s console port to your PC’s COM port. You may then use
a console terminal program, such as Moxa PComm Terminal Emulator, to access the VPort 351’s console
configuration utility.
Reset Button
A recessed RESET button is provided for rebooting and restoring the system to the factory default settings. Use
a pointed object, such as a straightened paper clip or toothpick, to press the Reset button.

Before Getting Started
In what follows, “user” refers to those who can access the video encoder, and “administrator” refers to the
person who knows the root password that allows changes to the Video Encoder’s configuration, in addition to
providing general access. Administrators should read this part of the manual carefully, especially during
installation.
Initial Installation and Configuration
Before installing the VPort 351 video encoder, verify that all the items in the Package Checklist are present. You
will also need a PC or laptop with an Ethernet port.
Step 1: Select the power source
The VPort 351 can use a 12 to 32 VDC power source or an 18 to 30 VAC power source. It has two power inputs
for redundancy. Users use the LED indicators on the front panel to verify that the power is connected. If a power
input fails, the FAULT LED will light up red.
NOTE
The VPort 351 supports a different range of power inputs than Moxa’s EDS line of Ethernet switches. The VPort
351 comes with two power inputs for redundancy. Each input supports 12 to 32 VDC for a 12/24 VDC power
source or 18 to 30 VAC for a 24 VAC power source. EDS switches support a 12 to 45 VDC power source.
Step 2: Connect the VPort 351 to the network
Depending on the specific model, your VPort 351 will have an auto-sensing 10/100 Mbps RJ45 Ethernet port or
a 100 Mbps single or multi-mode fiber optic port. Use the port to connect the VPort to the network. LEDs on the
network port will indicate whether the 10 Mbps or 100 Mbps connection is active.
Step 3: Connect the VPort 351 to a camera and an audio source
Use coaxial cables with BNC connectors to connect your camera to the VIDEO INPUT port and your monitor or
DVR to the VIDEO OUTPUT port. The VPort 351 uses a loop-through video output port DIP switch for activating
the 75-ohm resistor. The 75-ohm resistor should be set to OFF when video output is enabled.
You may plug a microphone or amplifier directly into the AUDIO INPUT port and a speaker into the AUDIO
OUTPUT port.
NOTE
The VIDEO LED on the front panel lights up when an active signal is detected on the video input port. Use this
LED to verify that video is working properly.
ATTENTION
A ground loop isolator is recommended to be used between the camera and the VPort to avoid a sudden
current, which is generated by the electric potential difference between these 2 device’s ground power, to burn
out the VPort’s chips and boards.
Step 4: Connect the VPort 351 to a PTZ camera
The VPort 351 allows remote control of a PTZ camera’s pan, tilt, and zoom from the network. You will need to
connect the camera’s PTZ control cable to the VPort 351’s PTZ port for PTZ control. The port is a 5-pin terminal
block that supports the RS-232, RS-422, and RS-485 interfaces. Please refer to Chapter 1 for the
RS-232/RS-422/RS-485 COM port’s pin assignments.
Use the VPort 351’s web console to configure and enable PTZ control. Note that there are different PTZ
protocols. The VPort 351 supports PTZ drivers for Pelco D, Pelco P and DynaColor DynaDome, and can be
customized to work with other PTZ protocols. Please contact a Moxa sales representative if you need assistance
from Moxa’s R&D department to create a new PTZ driver.

In addition, Transparent PTZ Control can be used for controlling a camera with a legacy PTZ control panel or
keyboard, which means all of kinds of PTZ cameras can be controlled without any PTZ driver requirements.
Users can connect legacy PTZ control panels or keyboards with the PTZ port of VPort D351 or the COM port of
a PC (provided Moxa Real COM port driver installed) to directly control the PTZ camera connected to the VPort
351.
NOTE
The PTZ control panel or keyboard must be able to control the PTZ camera being used.
Step 5: Configure the VPort 351’s IP address
When the VPort 351 is first powered on, the POST (Power On Self Test) will run for a few moments. The STAT
LED will turn green when the POST is complete. The NETWORK LED will then flash as the IP address is assigned.
The network environment determines how the IP address is assigned.

Network Environment with DHCP Server:
For this network environment, the unit’s IP address will be assigned by the network’s DHCP server. Refer to the
DHCP server’s IP address table to determine the unit’s assigned IP address. You may also use the Moxa VPort
and Ether Device Configurator Utility (edscfgui.exe), as described below:
1. Run edscfgui.exe to search for VPorts and EDS switches. After the Utility window opens, you may also
select or click on Broadcast Search, located under the List Server menu, or click on the Broadcast Search
icon to initiate a search.
NOTE
You may download the
Moxa VPort and EtherDevice Configurator Utility (edscfgui.exe)
software from
Moxa’s website at
www.moxa.com.
2. The Broadcast Search window will open, displaying a list of all switches and VPorts located on the network,
as well as the progress of the search.

3. When the search has concluded, the Model Name, MAC address, and IP address of the EDS Switch and VPort
will be listed in the Utility window.
NOTE
Broadcast Search can only be used to search for devices on the same LAN domain. If your devices are located
on a different LAN domain, use
Specify IP Address to search for the device by keying in the IP address.
4. Double click the selected VPort, or use the IE web browser to access the VPort’s web-based manager (web
console).
Network Environment without a DHCP Server:
If the unit is connected to a network that does not have a DHCP server, then you will need to configure the IP
address manually. The VPort 351 has a default IP address of 192.168.127.100 with a default subnet mask of
255.255.255.0. You may need to change your computer’s IP address and subnet mask so that the computer
and the VPort 351 are on the same subnet.
To change the unit’s IP address manually, open the unit’s web console and navigate to System Configuration
Network General. Make sure that Use fixed IP address is checked so that the IP address is not reset
every time the unit is restarted.
Step 6: Log into the VPort 351’s web console
In your web browser, navigate to the VPort 351’s IP address to open the web console.
