Thank you for your selection of the WI-MOD-E-100 and/or WI-MOD-E-300 Wireless
Ethernet Modem. We trust it will give you many years of valuable service.
ATTENTION!
Incorrect termination of supply wires may
cause internal damage and will void warranty.
To ensure your WI-MOD-E enjoys a long life,
double check ALL your connections with
the user’s manual
before turning the power on.
Caution!
For continued protection against risk of fire, replace the internal module fuse only with the same type
and rating.
CAUTION:
Antennas used with this device must be installed to provide a separation distance of at least 20 cm
from all persons to satisfy RF exposure compliance.
DO NOT:
operate the transmitter when someone is within 20 cm of the antenna
operate the transmitter unless all RF connectors are secure and any open connectors are properly
terminated.
operate the equipment near electrical blasting caps or in an explosive atmosphere
All equipment must be properly grounded for safe operations. All equipment should be serviced only
by a qualified technician.

Important Notice
Weidmuller, Inc. products are designed to be used in industrial environments, by experienced industrial engineering personnel with
adequate knowledge of safety design considerations.
Weidmuller, Inc. 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, Weidmuller, Inc. 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 Weidmuller, Inc. 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 WI-MOD-E Installation 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
WI-MOD-E 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 WI-MOD-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 WI-MOD-E module is not suitable for use in explosive environments without additional
protection.

Chapter One INTRODUCTION
The WI-MOD-E Industrial Wi-Fi Wireless Ethernet module provides wireless connections between
Ethernet devices or Ethernet wired networks (LAN’s). It complies with the IEEE 802.11b standard.
The WI-MOD-E has an internal 2.4GHz direct sequence spread spectrum (DSSS) wireless
transceiver, which can be used without a radio license in most countries. Users can select one of 11
5MHz wide channels, with the first channel centered at 2.412 GHz.
Note that regulations in North America and part of Europe permit all 11 channels to be
used in these countries. Please check with your Weidmuller, Inc. representative for the
permitted channel usage in your country.
The WI-MOD-E unit also provides two serial connections as well as the Ethernet connections. It is
possible to use all three data connections concurrently, allowing the WI-MOD-E to act as a Device
Server. Wireless connections can be made between serial devices and Ethernet devices, however
appropriate driver applications are required in the host devices to handle the different data format.
The WI-MOD-E does provide connection functionality between serial “ModBus RTU” devices and
Ethernet “ModBus TCP” devices.
The WI-MOD-E is available in two models with different RF power:
WI-MOD-E-100 100mW of RF power
WI-MOD-E-300 300mW of RF power
Note that European regulations do not permit more than 100mW of RF power to be used.
In USA, Canada and Australia, up to 1W of RF power may be generated. In other
countries, please check with your Weidmuller, Inc. representative.
The WI-MOD-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 rates between 1 and 11
Mbit/sec.
1.1 Network Topology
The WI-MOD-E is an Ethernet device, and must be configured as part of an Ethernet network. Each
WI-MOD-E must be configured as:
an “Access Point” or a “Client”, and
a “Bridge” or a “Router”.
You can also connect to the WI-MOD-E via a RS232 or RS485 serial port using serial server or PPP
(point-to-point) protocol. PPP allows the WI-MOD-E to connect serial communications into the
Ethernet network.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual
WI-MOD-E Manual v1.10 Page 8
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 first diagram shows two
Ethernet devices being linked. One WI-MOD-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 second diagram shows an existing LAN being
extended using WI-MOD-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 LAN end.
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 WI-MOD-E Clients which do not
have direct reliable radio paths.
Multiple Access Points can be set-up in a “mesh” network to provide multiple repeaters.
Page 9 February 2010
Bridge vs Router
Each WI-MOD-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.
If more than two routers are required within the same radio network, then routing rules may need to
be configured (refer section “3.11 Routing Rules” for further details). There is no limit to the number
of Bridges in the same network - although there is a limit of 128 Client units linked to any one Access
Point.

1.2 Getting Started Quickly
Most applications for the WI-MOD-E require little configuration. The WI-MOD-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 WI-MOD-E requires an antenna and a power supply.
Power the WI-MOD-E and make an Ethernet connection to your PC (for further information on
how to do this, refer to section 3.4)
Set the WI-MOD-E address settings as per section 3.4
Save the configuration - the WI-MOD-E is now ready to use.
Before installing the WI-MOD-E, bench test the system. It is a lot easier to locate problems when the
equipment is all together.
There are other configuration settings which may or may not improve the operation of the system.
For details on these settings, refer to section 3.
