Introduction
There are two generations of Model WNM our Current
model and our older Legacy model.
The older Legacy version has four models:
900 MHz band:
WNM /ETHERNET/…/-900 MHZ/…
WNM/SERIAL /…/-900MHZ/…
2.4 GHz band:
WNM/ETHERNET/…/-2.4GHZ/…
WNM/SERIAL/…/-2.4GHZ/…
The Current version of the WNM began in June 2015
has only two models. The following changes are
made:
Both ETHERNET and SERIAL communications are
combined into a single Model number for a given
band. When there is a requirement for Ethernet
communications, or for serial communication, or for
both communications methods, then specify the WNM
Model number by:
900 MHZ band (specify for Ethernet or serial or both):
WNM/ETHERNET/…/-900MHZ/…
2.4GHZ band (specify for Ethernet or serial or both):
WNM/ETHERNET/…/-2.4GHZ/…
The Current WNM version Ethernet radios are slightly
larger in package size. Refer to Figures 2.
Both Legacy and Current versions of the WNM
ETHERNET radios are electronically compatible
with one another. You will be able to use both the
Legacy and Current version ETHERNET radios in
the same RF network. However you can not use
Legacy ‘SERIAL only’ type radios in a network with
ETHERNET radios since the earlier Legacy
‘SERIAL only’ type radios use a different internal
radio-to-radio modems.
It is routine to use the serial ports with the ETHERNET
radios (both Current & Legacy). The serial
communications uses packets within the Ethernet
radio-to-radio modems link to carry the serial
information. The Model WNM is not a
‘serial-to-Ethernet protocol converter’. Which means,
if the data originates on a serial port on one Model
WNM, then it will be communicated to the serial ports
(only) of the other Model WNMs. The same wording
applies Ethernet origin port to other Model WNM
radio(s) Ethernet destination (only) ports.
When using the serial ports on these Model WNM
Ethernet radios, use care to allow at the serial device
source and serial device destination for additional
‘store and forward’ minor time delays originating
from within the Model WNM modems. Some serial
protocols expect precise timing of an arriving signal or
a eld response signal. If the source (or destination)
device has parameter adjustments to allow for timing
delays, then experiment with these settings until all
occasional data dropouts are eliminated. These minor
time delays are more pronounced when additional
repeaters or low RF signal strengths are involved.
The Model WNMs do perform an automatic ‘resend’
of data if the rst transfer of data was not successful.
This ‘resend’ adds further minor timing delay. Ethernet
based communications use a different exibility in
‘timing’ of data and are very exible in handling routine
timing delays with no operator setup intervention.
Both versions of WNM radios are congured for
radio and network setups using the newer WNM
Cong program (available from the Moore Industries
Internet site which is included with the purchase
of your WNM radios). The Legacy version WNM
radios may use a wireless network using any of the
four (4) network setup protocols- but only if ‘all of the
radios’ on the network are only the rst version. The
available combinations may vary in the rst version
WNM radios if the Model WNM is ‘Serial only’ or an
Ethernet (with serial). For any combination of rst and
second version WNM radio networks specify only the
Point-to-Point network or the SSE- Smart Switched
Ethernet type of network. The SSE may be used for
any application. The SSE must be used for networks
with WNM repeaters.
The WNM (Wireless Network Modem) transceivers are
modern, high performance, wireless radio modems
designed for reliable industrial data communications in
the 902-928 MHz license-free band and in the
2.4 - 2.4835 GHz international license-free band.
These wireless modems employ advanced spread
spectrum frequency hopping and error detection
technology to achieve very reliable noise and
interference immune operation.
Both our Current and Legacy WNM models are
available in two frequency band versions according to
the intended communications (900 MHz or
2.4 GHz). The precise frequencies within each band
and maximum power levels are factory congured and
will vary for different countries. All WNM models are
covered in this manual. Both WNM Current models
support Ethernet and serial communications.

From Moore Industries the WNMs are pre-congured
for immediate use. The WNMs provide a two-way,
transparent communications link for serial data and
Ethernet without the necessity to update any WNM
parameters such as baud rate, parity, stop bits,
protocol, broadcast messages, etc. The data stream
that arrives at one WNM COM port appears at the
other WNM COM port as if the original ‘wired cable’
were transparently connected between the WNM radio
pairs. Internal (WNM-to-WNM) data transfer is via
radio link data packets transferring at up to
1.1 Mbits/sec, with 128 bit AES (Advanced Encryption
Standard) secure data encryption, a 32 bit CRC
(Cyclic Redundancy Check), and ARQ (Automatic
Resend Query) to re-send data packets for data
integrity – all these activities are transparent to the
user.
Reliable point-to-point communication of up to 30
miles is achieved by using the 900 MHz band for
communications. This band is proven to minimize
signal loss over distance and even a slight ability to
penetrate and reect off walls on indoor environments.
The 2.4 GHz band is suited when required by
government regulations, when physically smaller
antennas are required, and/or for communications
distances of 15 miles or less. The 2.4 GHz band
range is limited since it is usually lower power and
also does not penetrate interior walls and trees/foliage
as readily as the 900 MHz band.
For expanded systems, or applications that may
require communicating beyond hills or longer
distances, the WNM may be congured to include
repeaters with a virtually unlimited number of WNM
transceiver remote sites all communicating back to a
master WNM. Communications may be one-way,
two-way back to the master site, or effectively from
any site-to-any site.
WNM transceivers obtain optimum range by careful
selection of antenna, antenna location, signal gain
parameters, coaxial cable, surge protection, and
conguration of the transceiver setup parameters
to match your particular application. We encourage
you to contact Moore Industries’ support personnel
to set up your WNM transceivers in advance of
purchase. The WNM Conguration Manager software
can also be used to make setup changes to your
wireless system, such as the addition of a new WNM
transceiver site for your applications.
Each WNM radio includes a 2 dBi exible antenna
which mounts directly to the RF connector on the top
of the WNM. This is used for bench testing prior to
system deployment. This antenna is usually replaced
by a coaxial cable and a larger antenna for greater
communications range.
The use of radios may be unfamiliar to some
personnel. Please use this manual as your guide
for your WNM radio familiarization, performance,
installation guidelines, safety considerations, and
diagnosis of operation.

Quick Setup Guide
WARNING
Please review the Important Safety
Information in the Installation section of this
manual before proceeding.
The following guide provides an outline of the steps
to planning, configuring and installing your WNM
network. For more detailed information please refer to
the relevant topics in this manual.
Network Architecture
1. Hand sketch your system on paper as to
physical layout (map). This includes the host
site plus all remote sites. It includes antenna
positions, distances, hills, and intervening
buildings/obstructions in the radio signal
pathway.
2. Determine where the ‘Master radio’ is to be
located (usually adjacent to the host NCS/
PLC/DCS).
3. Determine the need to provide a radio
repeater site for ‘far distant’ sites that cannot
‘see’ the ‘Master radio’. More than one
repeater may be required.
4. Determine if communications are to be
Ethernet, Serial, or both.
5. For long distance radio paths, or radio paths
that intersect other radio systems, perform
a radio ‘site survey’ using actual radios to
confirm that radio communications paths are
reliable for the various sites.
6. Determine your network architecture (one
site to one other site, or more than two sites)
Installation Planning
1. Select best locations for the WNM(s).
Generally these would be located closest
to their antenna, not their process
control equipment, to achieve the best
communication range. The WNM is usually
installed at the entrance of a building in a
weather resistant housing. Also included is
any RF (lighting) coax cable surge protection
plus a lighting earth rod at ground level.
Preferred is a short coax cable length from
the rooftop/tower to the WNM.
2. Select the optimum locations for your
antennas. Ideally these will be the physically
highest points such as atop a mast/pole
at the top of a building or tower with a
straight line of site from the antenna to
distant antenna(s) at other locations. The
higher the location of the antenna, the fewer
opportunities for the RF signal to reflect from
nearby surfaces to degrade the overall RF
signal strength.
3. Select suitable antenna types. An
omnidirectional antenna is well suited
for master control points with remote
sites in different directions. A directional
(Yagi) antenna is best suited for point-to-
point applications. Other antenna types
are available that are better suited for
applications where it is desirable to ‘hide’
the presence of the antennas. These may
include spike or flat panel antennas. Consult
Moore Industries for selection of these
antennas.
4. Select antenna gains. An antenna with
increased gain is generally recommended
to offset the losses of RF coaxial cable and
to increase effective radiated power for
improved communications range.
Warning:
Local and National Government guidelines
limit the effective radiated RF energy. Moore
Industries will assist in calculating the correct
radio power, antenna gains and RF cable
losses for your particular installation.

Configuration
Your WNM radios are pre-configured at Moore
Industries and are ready to use out of the box. If your
radios are purchased as part of a Moore Industries’
system, the radios have already been tested with
your particular system. The WNMs are also tagged to
identify their relative installation location.
The WNM Configuration program can be used to
modify and save the WNM setup and also to monitor
WNM radio performance. Please see the Configuration
section for more information.
Bench Setup
It is recommended to test your system setup in a lab
environment before installing in the field (if this is
practical).
1. Before connecting your WNM radios, hook
up your system with cables (Ethernet/
serial) and verify your system is successfully
communicating.
2. Replace the cables with the pre-configured
WNMs (using the tags to identify their
network location). For this test, the flexible
antenna already installed on the WNM can
be used.
3. Power up the system and simulate a signal
at one site. Monitor its appearance on
the other site. Check led activity on each
WNM communications port (see Figure 7
in Operation & Diagnostics section for LED
information).
4. Simulate data signals between all sites and
verify that they are communicating.
Field Installation
1. Move the WNMs into their final (permanent)
enclosures.
2. Replace the short flexible antennas on
the WNMs with their coaxial cables, surge
suppressors and antennas. The short
antennas should be stored safely (for future
maintenance purposes, as desired).
3. Verify the correct WNM radios (refer to
factory tags regarding Master and various
Remote) are installed at their correct sites.
4. Repeat your communications test.
5. If there are problems, note all LED status
indicators and contact Moore Industries
technical support.
Caution:
The optimum and safe use of WNM radios,
coaxial cable, surge protection devices,
and antennas requires an added RF (radio
frequency) knowledge that may not already
be in the experience set for some designers,
installers and maintenance personnel. Please
review all topics of this manual for more
detailed information and review and comply
with any local building codes.

Network Architecture
Prior to configuring your WNMs, you must first design
your network to determine the location, number and
types of WNMs required. Please review the sections
below for more information on radio and network types
to help in your network design.
1. Hand sketch your system on paper as to
physical layout (map). This includes the host
site plus all remote sites. It includes antenna
positions, distances, hills, and intervening
buildings/obstructions in the radio signal
pathway.
2. Determine where the ‘Master radio’ is to be
located (usually adjacent to the host NCS/
PLC/ DCS). All radio communications will be
routed through the Master radio regardless of
data origin and data destination.
3. Determine the need to provide a radio
repeater site for ‘far distant’ sites that cannot
‘see’ the ‘Master radio’.
4. Determine if communications are to be
Ethernet, serial, or both.
5. Perform a radio ‘site survey’ using actual
radios to confirm that radio communication
paths are reliable for the various sites. This is
particularly important for long distance radio
paths plus radio paths that intersect other
radio systems.
6. Contact Moore Industries-International
technical support staff for any questions and
assistance.
Radio Type
Each network consists of a one Master radio plus one
or more Remote radios. If a radio (Master or Remote)
pathway is obstructed or too distant to another radio,
then a Repeater radio must be added to the link.
Master Radio
All WNM communication network types must have a
Master radio. There is always only one Master radio
per WNM communications network. The Master radio
is physically identical to any other radio. It is given its
Master assignment and its own address at the time of
network configuration. In most WNM communications
networks, the Master radio is used to direct radio
traffic to/from each of the other radios. Thus, in most
networks, radio traffic to/from all of the other radios
is routed through the Master radio. The Master radio
is usually located at the site that has the most data
transfer. An example would be the host computer
site of a large facility that communicates with multiple
remote locations. By locating the Master radio at
this busy site, the minimum number of radio pathway
transactions is required for network communications.
Remote Radio
All network types have one or more Remote radios.
The Remote radio is physically identical to any other
radio. It receives its Remote assignment at the time
of network configuration. In most WNM network
types, the Remote radio communicates via a radio
addressing pathway through the Master radio. This
includes communications from one Remote site to
another Remote site, in most networks. The Remote
radios are usually located at the remote sites. Remote
radio sites may be added at any time to the network
by configuring the remote to communicate with a
particular other radio address, usually the Master or a
Repeater.
12 The Interface Solution Experts
WNM
Wireless
Network Module

Repeater Radio
A Repeater radio is required only when the radio
pathway is too distant or an obstruction exists between
the two sites. The Repeater radio is physically
identical to any other radio. It receives its Repeater
assignment at the time of network configuration.
The Repeater radio is situated at a location that can
‘see’ both of the other sites. A single Repeater may
also be used to communicate with multiple remote
sites. The Repeater is a digital ‘store and forward’
type of repeater in which an addressed radio packet
is received, briefly stored within the repeater, and
then the packet is transmitted to the next radio. The
Repeater radio configuration has its own address,
plus an assigned list of radios it is permitted to
communicate with on the network. A Repeater uses
one antenna for all communications. So the antenna
pattern (directions) must be considered for all relevant
sites. If a new radio site is edited (added, removed,
change of address) on a network, then the Repeater
configuration needs to be updated also.
A Repeater is also a Remote site. Thus any Repeater
also inputs and outputs data from its own site just
as at regular Remote site. Any Repeater may serve
both functions- Remote site and Repeater site
simultaneously.
Network Type
There are a number of different network types
available which determine how the master and remote
radios communicate with each other. Selection
of different network types optimizes data transfer
depending on the application. Available network types
depend on the type of radio you are configuring (Serial
or Ethernet) and not all network types are available on
all radios.
For Serial (Legacy Version Only) communication,
there are four network types:
P2P - Peer To Peer
PMP - Point to Multipoint
E2E - Everyone to Everyone
PTP - Point To Point
For Ethernet (Legacy and Current Version)
communication, there are two network
communications types:
P2P - Peer to Peer
SSE - Smart Switched Ethernet.
P2P (Peer to Peer) Network (Serial or
Ethernet)
In P2P (Peer to Peer) networks, all communications
are always routed through the Master radio.
Communications may be from:
a) any remote to the Master WNM radio;
b) the Master WNM to any WNM remote radio;
c) any WNM remote radio via the Master WNM
and then to any other WNM remote radio;
and
d) any WNM remote radio via the Master WNM
and then broadcast to all WNM remote
radios.
The Interface Solution Experts 13
WNM
Wireless
Network Module

PMP (Point to Multipoint) Network
(Serial only)
In PMP (Point to Multipoint) networks, the application
is well suited for a polled network in which an
addressed message is broadcast from the WNM
Master to all WNM remotes. Then only the properly
addressed WNM remote radio responds back only to
the WNM Master. MODBUS RTU communications
is typical of this structure. The sequence in Point to
Multipoint networks is:
a) Master radio broadcasts to all WNM remote
radios;
b) the proper WNM remote radio responds back
to the Master. The other WNMs are silent.
E2E (Everyone to Everyone) Network
(Serial only)
In E2E (Everyone to Everyone) networks, all WNM
remote sites communicate with all other WNM sites
by routing their messages via the WNM Master radio.
The WNM Master radio then sends this message to
every WNM remote radio. This method is bandwidth
intensive since all data is sent to all WNM sites.
PTP (Point To Point) Network
(Serial only)
In PTP (Point To Point) networks, some WNM radio
sites may be too remote for reliable direct radio
communications. The Point To Point network provides
a repeater communications link. Located in between
these two distant sites are dedicated WNM radio
repeaters programmed for the task of receiving the
message from one WNM radio, briefly storing the
data, then forward (transmit) the message to the next
WNM radio site. This next site may be another WNM
repeater or may be the destination.
SSE (Smart Switched Ethernet) Network
(Ethernet only)
Smart Switched Ethernet (SSE) configuration creates
a network suitable for any communication pattern
between WNMs. It efficiently determines whether to
broadcast to all radios or direct to a single radio on a
packet by packet basis. This encompasses PTP, PMP
and E2E network topologies. Each radio is able to
communicate with any or all other radios.
Suggestion: For all Model WNM networks (except
Serial only first version models) specify SSE. The
SSE is suitable for all Ethernet (or Ethernet with serial)
applications.

WNM Conguration
The WNM radios are pre-configured at Moore
Industries prior to shipping. They are also tagged
to indicate where each WNM is to be installed. If
no changes are required, then this section may be
skipped. However, the WNM Configuration program
also provides the ability to examine each existing
WNM setup, edit and save the setup, and also to
monitor WNM radio performance.
Note:
There are differences in Ethernet radio versus
Serial only radio network types and their
respective configurations. These are explained
in the previous Network Type Section.
The WNM Configuration program is the software tool
to design and configure the WNM communications
network hardware. The network consists of a one
Master radio plus one or more Remote radios. If a
radio (Master or Remote) pathway is obstructed or
too distant to another radio, then a Repeater radio
assignment is made.
In all networks, the WNM Configuration program uses
the identical radio hardware, but configures these with
their respective task (Master, Remote or Repeater)
plus addressing.
General Radio Configuration
Prior to configuration, have your system architecture
completely documented in writing for each WNM site.
WNM radios are configured one at a time. However,
once a network has been configured and successfully
tested, edits may be performed on installed WNM
radios at remote sites by communicating through the
WNM Master radio.
Note:
There is a sequence to editing radio
configurations. This editing may be performed
on the bench or ‘on the air’ in an ‘already
configured and operational’ communications
network. Use care when editing ‘on the air’
to edit the furthest WNM site address (and
pathway) one at a time prior to editing any
intermediate sites (repeaters) or nearby
sites such as the master. All sites need to
‘know’ through the configuration process their
particular pathway back to the Master. If the
Master or a repeater is configured prior to
the furthest remotes, then the communication
pathway addressing is incorrect
(discontinuous) for the further downstream
remote WNM’s. This will require a field trip to
program the ‘now incorrectly (discontinuous)
addressed’ remote sites on an individual basis.
It is recommended that all WNM radio configurations
be performed on the workbench and checked for
successful communications prior to being deployed
into the field site. Should the radio signal strength
exceed -40 dBm (a very strong RF signal being
received), some radio performance may be temporarily
degraded such as occasional missed packets. If so,
relocate the antennas, separate the radios further, or
disconnect the antennas during workbench testing.
When starting a WNM radio network configuration,
always begin with the Master radio. Then configure
each additional radio one at a time until all radios are
configured. The WNM Config program enables you to
semi-graphically lay out your entire network identifying
the WNM master radio, all other WNM radios, and the
network links in-between radio sites. Use this same
program to save your setups on a PC, recall these
setups from storage memory for future editing / growth
to the network, and also to download the setups from
each WNM.

Connecting the WNM to
the PC
Connect the computer to your WNM Master radio as
follows. These same connections apply to all other
WNM radios. Connect the computer to only one WNM
radio at a time.
For Ethernet WNM radio (WNM/ETHERNET...):
Connect an Ethernet crossover cable directly
from the laptop RJ45 connector to the WNM
radio RJ45 connector.
Or;
Connect a straight Ethernet cable from the
laptop RJ45 connector to an Ethernet LAN
switch (or hub) and then another straight
Ethernet cable from the Ethernet LAN switch
(or hub) to the WNM radio RJ45 connector.
For Serial only WNM radio (WNM/SERIAL...):
The radio is a DCE device. The laptop is a
DTE device. Use a straight DB9-to-DB9 serial
cable between the laptop DB9 serial port and
the WNM ‘CONFIG’ DB9 serial connector.
This DB9 connector is on the same side as
the RF connector.

Example
Load and run the WNM Configuration program. The
following is familiarization to set up a small network
and then download to the respective WNM radios.
1. Navigate to ‘Configure’ and click. This
activates the pull down menu.
2. If defining a new radio network, then select
“New Network” and click. If you have
previously saved Network Configuration files,
then these are available via ‘Modify’ and a list
of saved networks will appear.
3. The Network properties screen appears.
a) Assign the ‘Network Name’ for this radio
network. This is later saved on the laptop
hard disk as the filename for this particular
network. In the future, these saved networks
may be retrieved via ‘Configuration’, ‘Modify’,
then the network name.
b) Select ‘Radio Type’ using the pulldown menu.
Available selections are:
WNM- Ethernet (Legacy version or Current version)
WNM- Serial (Legacy version only)
Subsequent pulldown menus dynamically
changed based upon your selection here.
You will want to select ‘IFHE’ for all Ethernet
Model WNM.
c) Select ‘Network Type’ Selection options are
on a pulldown menu. For all Ethernet radios,
select ‘SSE-Smart Switched Ethernet’. For
‘Serial only’ select your preferred network
type.
d) Select ‘Network Channel’. WNM radios
communicate on groups of frequencies
labeled here as a ‘channel’. If no other
radio networks are operating nearby, select
any channel. If multiple radio networks are
operating nearby, then select a different
channel for each network to minimize the
risk of brief radio interference from other
networks momentarily sharing the same
frequencies.
e) The Wireless Link Rate is entered here. For
all Ethernet radios usually the highest rate
is entered. The exception is to use a lower
rate to improve the signal-to-noise when
communicating very long distances and
thus low RF signal levels are present, or
when interference from external sources is
expected.
In Serial only radios, usually the highest
rate is entered. This will minimize store and
forward time delays. If a noisy RF path or
low level RF signals are expected, then use
a lower rate. You may need to adjust this
rate, based upon application experience,
to minimize data delays arriving at the
destination site. This Model WNM data rate
is the radio-to-radio RF modem. It is not
the same as the serial port (RS232/RS485/
RS422) port rate.

f) RF Encryption Level is normally set at 128-
bit AES via the pull down menu. Optionally
you may select ‘Disabled’ if no encryption is
desired. Passphrase is alphanumeric, upper
and lower case.
g) The ‘Help’ button hyperlinks to the Internet
version of this technical manual. The Internet
version of the technical manual is always the
most up-to-date.
4. Click the OK button on the bottom of the
screen to accept the network. This also
downloads a default template consisting of a
default ‘two radio’ network. You can also add
new radios to the network as desired.
Navigate to ‘Radio’. From the pulldown menu
select ‘Add Radio’. ‘Radio 3’ appears. Use
your mouse to click on Radio 3 and drag to
a position below ‘Radio 2’. Use your mouse
to point at the black dot of ‘Radio 3’ and drag
this point towards ‘Radio 1’. This dragging
defines the communications link between
‘Radio 1’ and ‘Radio 3’. If you incur a
mistake, then use the mouse to highlight the
unwanted radio, navigate to the top of screen
to ‘Radio’ and from the pulldown menu select
‘Remove Radio’.
Setting Up the Master Radio
The WNM radios are designed to operate as a
transparent communications link. That is, the WNM
radio replaces the original Ethernet cable or serial
cable that previously joined a field instrument with
another field instrument or with the host DCS/PLC.
Every radio network requires one Master WNM radio
plus one or more Remote WNM radios. From the
above screen, navigate to ‘Master Radio’.
The settings of this screen are straightforward. The
default settings usually apply without modification.
For the Master radio, the Ethernet IP address
assigned by the IT Department for this particular
network. This IP address is for this particular WNM
on the network. Use this address to obtain diagnostic
information for this radio. Each WNM Ethernet radio
is to be assigned a different IP address. The ‘Gateway’
for the Master Radio is frequently its own ‘IP’ address.
The ‘Gateway’ for remote WNM radios is usually the
same as shown here, also shown are the ‘Serial
settings’ options with ‘Serial Protocol Encapsulation’.
When communicating with serial, the WNM and the
DTE equipment must be configured for the same
serial port setups of baud rate, word length, parity,
stop bits, and handshaking
Not shown here are the ‘Advanced Settings’.

With the Master Radio physically connected to the
laptop computer via an Ethernet cable, press the
‘Select Radio’ button. The WNM Config program will
perform a ‘Discovery Scan’ to identify what radios
are interrogate the Master radio for its MAC address
and initial IP address, Subnet Mask and Gateway. An
example of this WNM Config scan is:
If the Master radio is already operating in a network
and the other radios are communicating with this
Master Radio, then all radios will be listed. In the
above screen, only the Master Radio is active. By
pressing on the ‘Clear’ button, the list is erased. Use
the ‘Scan’ button to perform a new Discovery. This is
helpful if the ‘Radio Name’ column does not clearly
identify particular radio hardware.
Upon successful identification of the Master Radio,
use the mouse to highlight the desired radio. Then
select IP Settings. The WNM Config program will
further discover additional information and display as
follows:
If the WNM Config program does not successfully
identify the Model WNM IP address; or the ‘Config
Radio’ button does not operate then perform the
following checks:
a) Verify the computer (or laptop) does not
have a second Ethernet port already active.
Your WNM Config may be attempting to
communicate with a different computer
(laptop) port.
b) If on a laptop, temporarily disable the
laptop ‘wireless’ button. This wireless button
usually connects to the outside Internet.
c) Inspect the laptop computer security
programs, firewall settings and antivirus
programs.
d) Verify your own computer (laptop) Ethernet
port is not already using the identical
Ethernet port IP address assignment for itself
or another device on this Ethernet cable.
e) The Ethernet cable is not connected to
the Model WNM, or the Model WNM is not
powered to ON, or the Model WNM is not
already communicating with other WNM
radios in the same network (for example:
configuring a Model WNM at a remote site
via wireless).
This is the existing IP address, Subnet, and Gateway
for the Master Radio. This is the same screen to
edit these three settings. Upon completion of edits,
press the ‘OK’ button on this Radio IP Settings screen.
Press ‘OK’ on the ‘Radio Discovery Tool’ screen.
This returns you to the earlier ‘Radio Configuration
– Master Radio’ screen. The Master radio hardware
is not yet ‘configured’ with this new IP information.
Press the ‘Configure Radio’ button to download this
information to the Master Radio.
