Safety Instructions
Use the following safety guidelines to help protect your MGW
2000e unit from potential damage and to ensure your own
personal safety.
When using MGW 2000e
As you operate MGW 2000e, observe the following safety
guidelines
Note
Do not open the MGW 2000e unit, as this will void your warranty. MGW
2000e does not contain any user serviceable parts.
•Before installing MGW 2000e, unplug the system to help
prevent electric shock or system board damage. Certain
system board components continue to receive power any
time MGW 2000e is connected to AC power.
•To help prevent electric shock, plug the power cable into
properly grounded sources. Use only properly grounded
extensions and adaptors as the need arises.
•Use only a UL Recognized power cord.
•Make sure nothing rests on your MGW 2000e power cable
and that the cables are not located where they can be
stepped or tripped over.
•Do not spill food or liquids on your MGW 2000e unit.
•Do not push any objects into free slots of your MGW 2000e
unit. Doing so will damage your MGW 2000e unit and can
cause fire or electrical shock by shorting out interior
components.

•Keep your MGW 2000e unit away from radiators and heat
sources. Also, do not block cooling vents. Avoid placing
loose papers underneath your MGW 2000e unit. Do not
place your MGW 2000e unit in a closed-in wall unit or on a
bed, sofa, or rug.
•When you disconnect a cable, pull on its connector or on its
strain relief loop, not on the cable itself. Some cables have a
connector with locking tabs; if you are disconnecting this
type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins.
Also, before you connect a cable, make sure both
connectors are correctly oriented and aligned.
•ESD Warning: Normal handling precautions should be
taken to avoid static discharge.

MGW 2000e Overview
MGW 2000e transmits multiple channels of live TV and video
over IP networks. It can receive up to six live analog signals,
encode them in real-time to MPEG-1 or MPEG-2 and then
stream them over an IP network in multicast or unicast mode.
With MGW 2000e, organizations can utilize their IP networks
for business TV, training and corporate communications.
MGW 2000e encodes, multiplexes and transmits up to 6 live
MPEG-2 and MPEG-1 streams.
A Web-based remotely controlled management application lets
you configure, control and operate multiple streams.
MGW 2000e ships with two network interface cards (NIC)
enabling you to transmit streams over one NIC and use the
second one to configure and operate MGW 2000e.
This guide instructs you on how to connect MGW 2000e to a
network and initialize for the first use. It also guides you in
encoding one live channel from an analog or digital source with
pre-set default parameters.
Detailed instructions on setting streaming and encoding
parameters can be found in the user manual.

HyperTerminal connection.
You may add and configure conections manually or use pre-
configured configuration files available on the MGW 2000e
CD.
•To use pre-configured configuration files, refer to the next
page.
•To add the required connections manually, refer to the user
manual.
Before you initialize MGW 2000e:
1. To avoid network conflicts, make sure that no other
network device with the hostname MGW2000E is
connected to the network.
2. Use a serial cable to connect MGW 2000e's RS-232 port to
a free serial port (e.g. COM1) on the Configuration PC.
3. Use a network cable to connect MGW 2000e's NIC A to
the network.
•To connect NIC B as well, refer to the user manual for
further information and instructions.
Note
To ensure proper network communication, we recommend using shielded
Category 5 network cables.
