VPort 251 User’s Manual Getting Started
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 251 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: 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 intup 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 251 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 251 to a camera and an audio source
Use coaxial cables with BNC connectors to connect your camera to the VIDEO INPUT port.
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.
Step 4: Connect the VPort 251 to a PTZ camera
The VPort 251 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 251’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 251’s web console to configure and enable PTZ control. Note that there are
different PTZ protocols. The VPort 251 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.
A Transparent PTZ Control for controlling cameras with a legacy PTZ control panel or keyboard
is also available. This means that you will be able to control a variety of different PTZ cameras
without needing to worry about meeting PTZ driver requirements. Users can connect legacy PTZ
control panels or keyboards to the VPort D251’s PTZ port, or the COM port of a PC (provided the
Moxa Real COM port driver is installed) to control the PTZ camera connected to the VPort 251.
