First-Time Installation and Configuration
Before installing the VPort 351 video encoder, check to make sure that all
items in the Package Checklist are in the box. In addition, you will need to
use a notebook or PC equipped with an Ethernet port.
Step 1: Select the Power Source
The VPort 351 can be powered by a DC power input from 12 to 32 VDC, or
an AC power input from 18 to 30 VAC. Two power inputs are provided for
redundancy. Users can check the LED status located on the front panel to
see if the power inputs are connected appropriately. If one of the power
inputs fails, the FAULT LED will illuminate in red.
NOTE
The VPort 351 has 2 power inputs for redundancy. Each power
input supports 12 to 32 VDC for a 12/24 VDC power input, or 18
to 30 VAC for a 24 VAC power input. This differs from Moxa’s EDS
switches, which support a 12 to 45 VDC power input.
Step 2: Connect VPort 351 to the Network
The VPort 351 has an auto-sensing 10/100 Mbps RJ45 Ethernet port, or
100 Mbps fiber optic port (multi mode or single mode) for network
connectivity. Both the RJ45 port and fiber optic port have separate LEDs
for 10 Mbps and 100 Mbps connection activity.
Step 3: Connect the VPort 351 to a camera and an audio source
The VPort 351 has a VIDEO INPUT port and a loop-through VIDEO
OUTPUT port with a 75Ω resistance dip switch. Users should use the BNC
connector and coaxial cable to connect the video camera to the VPort to
input analog video signals, and connect the monitor or DVR with the VPort
to output analog signals (note that the 75Ω resistance should be turned to
off when the video output is enabled).
The VPort 351 has 1 audio input and 1 audio output. A microphone or an
amplifier can be plugged directly into the AUDIO INPUT port; a speaker
can be plugged into the AUDIO OUTPUT port.
NOTE
A VIDEO LED is located on the front panel to indicate the video
signal transmission status for the video input. Users can check
the LED status to see if the 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: Connecting the VPort 351 to a motorized PTZ
camera/device
If you are using a PTZ camera or device, you need to connect the PTZ
control cable to the VPort 351’s PTZ port. The PTZ port is a 5-pin terminal
block for RS-232/422/485 serial connection. The pin assignments are
shown below.

To enable PTZ control, configure the PTZ control protocol in the
web-based manager.
NOTE
The PTZ control protocol is not standardized. To use a particular
PTZ control protocol, the video server 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
If you need to use 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 program its PTZ control in the VPort 351’s
Custom Camera function.
NOTE
The VPort 351 comes with a PTZ driver upload func
tion for
implementing 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.
NOTE
The “Transparent PTZ Control” function in the camera driver list is
used to transmit the
PTZ control signal over a TCP/IP network to
the VPort D351 video decoder or PC (additional driver required).
The PTZ control panel or keyboard can directly control the PTZ
camera or device, eliminating the need for a PTZ camera driver
and allowing the use of PTZ cameras with the VPort encoder.
Step 5: Configure the VPort 351’s IP address
After powering on the VPort 351, wait a few seconds for the POST (Power
On Self Test) to run. The STAT LED turns green to indicate that the POST
process has completed. The IP address will be assigned when the 10 or
100 Mbps NETWORK LED blinks. The IP address assigned after the POST
is completed depends on the network environment.
Network Environment with DHCP Server
In this case, the IP address of the VPort 351 is assigned by a DHCP Server.
Use the DHCP Server’s IP address table, or use the Moxa VPort utility to
determine the IP address that was assigned by the DHCP Server.
NOTE
After powering on the VPort 351, wait a few seconds for the POST
(Power On Self Test) to run. The IP address will be assigned when
the 10 or 100 Mbps NETWORK LED blinks.

the VPort’s web-based manager (web console).
Network Environment without DHCP Server
If your VPort 351 is connected to a network that does not have a DHCP
server, then you will need to configure the IP address manually. The
default IP address of the VPort 351 is 192.168.127.100 and the default
subnet mask is 255.255.255.0. Note that you may need to change your
computer’s IP address and subnet mask so that the computer is on the
same subnet as the VPort.
To change the IP address of VPort manually, access the VPort’s web
server, and then navigate to the System Configuration Network 
General page to configure the IP address and other network settings.
Checkmark Use fixed IP address to ensure that the IP address you
assign is not deleted each time the VPort is restarted.
