Safety
Before using this unit:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
Hazardous voltage may occur within this unit when connected to power supply or
TNV circuits.
Prevent access to hazardous voltage by disconnecting the unit from power supply
and all other electrical connections.
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap).
Before installation:
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
Branch circuit protection (fuse) is required for this unit with rating not exceeding
20 A.
This unit uses convection cooling. To avoid obstructing the airflow around the
unit, follow the spacing recommendations (see Installation section).
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.
This unit must not be operating with removed covers or lids.

Introduction
The EDW-100 is an Industrial Ethernet to serial adapter or Ethernet Terminal Server. The
serial interface is selectable between RS-232 and RS-422/485. The Ethernet interface is
10/100BASE-T and supports the following networking protocols: TCP, UDP, ICMP, IGMP,
HTTP, ARP.
Two EDW-100 can be used to provide a serial point to point link over an Ethernet
network using either UDP or TCP. When using TCP the EDW-100 can be configured as
client or server.
In addition to a transparent serial point-to-point link and ethernet to serial adapter, the
EDW-100 MG can also be configured to act as a Modbus gateway.
Each unit passes data
from its serial interface
to the serial interface
of the other unit. This
enables long distance serial
communication using preexisting networks.
When EDW-100 is used
with the UDP protocol
it is also possible to
communicate one to many
(e.g. master to multiple
slaves), by using a broadcast
address or multicast

EDW-100 can also provide a remote serial interface
for a computer connected through a TCP/IP network
using a comport redirection software.
A COM port redirector or customer written
software can be used to create virtual COM ports.
This software will redirect data, originally sent to a
local COM port, to the remote serial interface of the
EDW-100. No changes are required on the computer
application software.
