Important Notice
ELPRO products are designed to be used in industrial environments, by experienced industrial engineering
personnel with adequate knowledge of safety design considerations.
ELPRO radio products are used on unprotected license-free radio bands with radio noise and interference.
The products are designed to operate in the presence of noise and interference, however in an extreme case,
radio noise and interference could cause product operation delays or operation failure. Like all industrial
electronic products, ELPRO products can fail in a variety of modes due to misuse, age, or malfunction. We
recommend that users and designers design systems using design techniques intended to prevent personal
injury or damage during product operation, and provide failure tolerant systems to prevent personal injury or
damage in the event of product failure. Designers must warn users of the equipment or systems if adequate
protection against failure has not been included in the system design. Designers must include this Important
Notice in operating procedures and system manuals.
These products should not be used in non-industrial applications, or life-support systems, without consulting
ELPRO Technologies first.
1. A radio license is not required in some countries, provided the module is installed using the aerial and
equipment configuration described in the 905U-EInstallation Guide. Check with your local
distributor for further information on regulations.
2. Operation is authorized by the radio frequency regulatory authority in your country on a non-
protection basis. Although all care is taken in the design of these units, there is no responsibility
taken for sources of external interference. Systems should be designed to be tolerant of these
operational delays.
3. To avoid the risk of electrocution, the aerial, aerial cable, serial cables and all terminals of the 905U-
D module should be electrically protected. To provide maximum surge and lightning protection, the
module should be connected to a suitable earth and the aerial, aerial cable, serial cables and the
module should be installed as recommended in the Installation Guide.
4. To avoid accidents during maintenance or adjustment of remotely controlled equipment, all
equipment should be first disconnected from the 905U-E module during these adjustments.
Equipment should carry clear markings to indicate remote or automatic operation. E.g. "This
equipment is remotely controlled and may start without warning. Isolate at the switchboard before
attempting adjustments."
5. The 905U-E module is not suitable for use in explosive environments without additional protection.

905U-E Wireless Ethernet User Manual
Man_905U-E Rev 1.0 Draft Page 8
Chapter One INTRODUCTION
The 905U-E Wireless Ethernet module provides wireless connections between Ethernet devices or Ethernet
wired networks (LAN’s). It has an internal 900MHz spread spectrum frequency hopping wireless
transceiver, which can be used without a radio license in many countries.
The 905U-E has a standard RJ45 Ethernet connection which will operate at up to 100Mbit/sec. The module
will transmit the Ethernet messages on the wireless band at up to 200 Kbit/sec.
1.1 Network Topology
The 905U-E is an Ethernet device, and must be configured as part of an Ethernet network. Each 905U-E
must be configured as:
qan “Access Point” or a “Client”, and
qa “Bridge” or a “Router”.
Access Point vs Client
The Access Point unit acts as the “wireless master” unit. The
Access Point sets up the wireless links to the Client units,
and controls the wireless communications. The following
diagram shows two Ethernet devices being linked. One
905U-E is configured as an Access Point and one as a Client
-in this example it doesn’t mater which unit is the Access
Point.
The next diagram shows an existing LAN being
extended using 905U-E’s. In this example, the
Access Point should be configured at the LAN end
-although the wireless link will still work if the Client
is at the LANend.
An Access Point can connect to multiple Clients. In this
case, the Access Point should be the “central” unit.

An Access Point could be used as a “Repeater” unit to connect two 905U-E Clients which do not have
direct reliable radio paths.
Bridge vs Router
Each 905U-E is configured with an IP address for the Ethernet side, and another for the wireless side.
A Bridge connects devices within the same Ethernet network -for example, extending an existing Ethernet
LAN. For a Bridge, the IP
address for the wireless side is the
same as the Ethernet side.
A Router connects devices on
different LAN’s. The
IP addresses for the
Ethernet and wireless
sides are different.
In the above example, the wireless link is part of LAN A, with the Client unit acting as a Router between
LAN A and LAN B. Alternately, the Access Point could be configured as a Router -the wireless link is
then part of LAN B.

There is limit of two Routers within the same radio network. There is no limit to the number of Bridges in the
same network -although there is a limit of 255 Client units linked to any one Access Point.
1.2 Getting Started Quickly
Most applications for the 905U-E require little configuration. The 905U-E has many sophisticated features,
however if you don’t require these features, this section will allow you to configure the units quickly.
First, read Section 2, “Installation”. The 905U-E requires an antenna and a power supply.
qPower the 905U-E and make an Ethernet connection to your PC (for further information on how to do
this, refer to section 3.3)
qSet the 905U-E address settings as per section 3.4 -also select Access Point / Client and Bridge /
Router
qSave the configuration -the 905U-E is now ready to use.
Before installing the 905U-E, bench test the system. It is a lot easier to locate problems when the equipment
is all together.
There are other configuration setting which may or may not improve the operation of the system. For detail
on these settings, refer to section 3.
