The simplest way to design the physical network of radios, antennas, connectors,
cables, amplifiers and other accessories, is to use ProSoft Wireless Designer
(page 15). This application determines your hardware needs based on your
answers to a few questions, and then generates a Bill of Materials specifying all
the components you will need for your installation.
To begin, determine where you need radios and then choose locations for
them accordingly. For example, you might decide to install your master radio
near a PC in a central plant location (You can use the PC to configure the
radios through the Radio Configuration / Diagnostic Utility). If the plant is an
oil refinery, for example, you might decide to install radios near the oil tanks.
The next important issue is how to link the radios. Unless the radios are very
close together, you must make sure that each pair of radio antennas in the
network has a line of sight between them. In other words, you must be able to
see from one antenna to another, either with the naked eye, or with
binoculars.

RadioLinx® 802.11a Industrial Hotspot User Manual
If a line of sight does not exist between antennas, you must choose a site for
installing a repeater radio, which will create a bridge between the radio
antennas.
Choose the appropriate antennas for the network. If an antenna will be
connected to the radio by a long cable, you might need to purchase a power
amplifier, which is available from ProSoft Technology. The more distance
between an antenna and its radio, the more signal loss the radio will have.
Consider drawing up your network plans on paper. As part of the drawing,
you should assign a logical name to each radio. You can use these names
later when configuring the radios in the Radio Configuration / Diagnostic
Utility.
As part of your planning, you might want to conduct a site survey. ProSoft
Technology can perform this survey, you can do it yourself, or you can hire a
surveyor.
Protect radios from direct exposure to weather, and provide an adequate,
stable power source. Make sure that your plan complies with the radio’s
power requirements and cable specifications.
Important: Radios and antennas must be located at least 8 inches (20 cm) away from personnel.

1.6.3 Planning the Physical Installation
A network's performance is affected by attributes specific to the installation site.
Consider the following cautions, where possible, to optimize your network
installation:
Design the network to use less than 2048 radios (per network)
Place radios within the specified 15 miles of each other
Add repeater to extend distance or where line of sight is limited
Radios or antennas CANNOT be placed within 8 inches (20 cm) of where
people will be
Though radio frequency communication is reliable, sometimes its performance
can be affected by intangibles. A good network installation plan includes time
and resources for performance testing and installation changes.
Test the installation plan (page 28) before the network installation is complete.
1.7 Configuring the Radios
To configure the network radios, follow these steps.
Use the RLX-IH Browser to display all radios on the network, and then use a
Web browser or SNMP manager to view and change radio settings. The radio
package includes the program CD, power supply, Ethernet cable, and a small
antenna. You must install the antenna later, but it is not needed to get started.
IMPORTANT: If possible, you should configure all the radios side by side in an office setting and
make sure they link before you try to install them in the field.
To configure the radios in a network:

Note: The master is the "root" or top-level radio in a network. You must have at least one master
radio per network. For redundancy, you can assign more than one master to a network.
To configure a Master radio, make the following changes to the web
configuration form:
Radio Network Settings
Radio Name: Enter a unique name for the radio.
Select Master as the radio mode.
Network SSID: Assign a network name (SSID) of up to 32 characters. The
radio uses this name in all network references. All radios in a network must
have the same SSID.
Channel: Select a channel and frequency range for the network or accept the
default value. Network channels allow radios to avoid sharing a frequency
with other networks in the same location. The channel list indicates the
channel number as well as the frequency.
Important: The RLXIB-IHA radio is supplied with a dual-band antenna that supports both
frequency ranges. If you use a different antenna with the RLXIB-IHA radio, you must choose a
channel and frequency range supported by the antenna.
Security Settings
Encryption Type: Encryption scrambles data so that only intended viewers
can decipher and understand it. Although "none" is an available encryption
type, ProSoft Technology strongly recommends encrypting all data sent and
received from every radio on your network, to help prevent your data from
being intercepted and decoded.

WPA phrase: To use WPA encryption on packets sent between the radios,
select WPA in the Encryption Type field. Next, in the WPA phrase field, enter
a pass phrase of between eight and 63 normal keyboard characters. This
phrase automatically generates an encryption key of 128 hexadecimal
characters. The default pass phrase is "passphrase" (lower case, no quotes).
For more information on encryption, see Security settings (page 59).
Because you must assign the same Network SSID and WPA phrase to the
repeater radios later in this procedure, you should write down the settings.
Note: Network SSID and WPA phrase are both case-sensitive.
Network SSID:_________________
WPA phrase:__________________
Radio Access Settings
If a DHCP (Dynamic Host Control Protocol) server is configured on your local
area network, the DHCP server can assign IP addresses automatically.
If you prefer to assign a Static (Fixed) IP address, select "Use the following IP
address", and then enter the IP Address, Subnet Mask and Default Gateway in
the Radio Access Settings area of the IH Radio web configuration form.
Important: If you intend to assign IP addresses manually, you must not duplicate an IP address
that is already in use on your network. If you are not sure what IP addresses are available, ask
your network administrator for assistance.

By default, a repeater connects automatically to the best available parent radio
on the network. If necessary, however, you can click the Parent Link button and
specify how repeater radios connect to the network. See Parent Link settings for
information.
1.7.8 Set Up a Client
Client mode is a special mode in the radio that allows a user to connect an
Ethernet device to a wireless network through any 802.11a access point. Any
Ethernet device that has an RJ45 Ethernet port can, in effect, be transformed into
an 802.11a wireless client by attaching the radio. Only a single device can be
connected to the radio in client mode. Do not connect to more than one Ethernet
device (using a switch or hub).
You only use client mode if you need to connect to another brand 802.11a
access point. If you are using RLXIB-IHA radios, you should always use them as
repeaters (and masters).
To connect a device to a radio in client mode, click the Client button for the radio
and try programming the radio’s client mode using the Auto setting. To test
whether the Auto setting will work:
1 Connect the cable between the device and the radio.
2 Turn ON the radio power, or cycle the power if the radio is already on.
3 Turn ON the device. Watch the radio to see if it initializes. The Auto setting
will work if the device advertises its MAC ID to the radio.
If the radio’s RF LEDs do not show consistent activity after a few minutes, then
you may need to modify the radio’s client settings. Click the Specify radio button,
determine the MAC ID of the Ethernet device, and type the ID into the Client
MAC field.
Client radios are preceded by a 'C' in the list of radios in the RLX-IH Browser.
1.8 Verify Communication
When configured, the name of each radio is preceded by an M (for Master), an R
(for Repeater), or a C (for Client) in the IH Browser window.
Look at the LEDs to ensure good link quality, as explained in LED display (page
32). After a repeater is configured, you can unplug the Ethernet cable from it.

2 Installing the Radios
If possible, you should configure all the radios side by side in an office setting
and make sure they link before you install them in the field. If feasible, it would be
even better if you could set up the entire system in the office and make sure your
equipment communicates properly through the radio network.
Important: If the radios are close enough to each other that their received signal strength is
greater than -40dBm, performance may be degraded. Disconnect antennas from radios during
bench testing, or move the radios further apart from each other.
Tip: To make it easier to physically identify the radios you are configuring, apply a label to each
radio indicating the radio name and IP address.
After you have configured each radio using IH Browser and the web configuration
form, you can install the radios and test their performance. Install the radios in
their proposed permanent locations, then temporarily place each radio’s antenna
near its proposed mounting location. The temporary placement of the antenna
can be by hand; however, with this testing method, one person must hold the
antenna while another monitors the radio’s signal strength.
To see how a radio is linked in the network, make sure that the radio is
connected to a PC, and then select Topology View from the View menu in the
RLX-IH Browser.

User Manual RadioLinx® 802.11a Industrial Hotspot
The Topology view shows a diagram of the network’s wireless connections. Use
this view to see whether all the radios are linked, and that you approve of the
way the radios are linked. A radio that is not linked to a parent will show as a
circle outlined by a flashing dashed red line. It may be near the bottom of the
window, so scroll down to view all available radios. To change how radios link to
the network, see Parent Link settings.
Refer to Improve Signal Quality (page 35) for more information on overcoming
poor connectivity.
2.1 Connecting antennas
Each radio must have an antenna connected to the Main antenna port on the
RLXIB radio; without an antenna for each radio, the network will not function.
All antennas for radios that communicate directly with each other should be
mounted so they have the same antenna polarity. Small antennas with a reversepolarity SMA connector can be mounted directly on the radio. Screw the antenna
onto the antenna port connector until it is snug.
Larger antennas and antennas that do not have a reverse-gender SMA
connector must be mounted separately and connected to the radio using a
coaxial antenna cable. Because the antenna cable attenuates the RF signal, use
an antenna cable length that is no longer than necessary to ensure optimum
performance.
Important: If the radio is to be used in a hazardous location, the radio must be mounted in an
enclosure approved for hazardous locations. The radio requires a separate cable connection to the
SMA connector that leads to an internal antenna.
2.2 Testing the Network Installation Plan
Test proposed installations before finalizing the installation.
After you have configured the network and the radios:
install the Master radio in its proposed permanent location
cable the Configuration PC to the Master radio
place the Remote radios in their proposed locations
temporarily place each radio's antenna near its proposed mounting location.
The temporary placement of the antenna can be by hand, however, with this
testing method, one person must hold the antenna while another monitors the
Remote radio's signal strength as displayed on the Configuration PC.
To improve the signal quality of each Remote's communication:
increase the height of the antenna's placement
use higher-gain antennas
increase the radio's transmission power, cable the radio to the Configuration
PC, and reconfigure it
select a new location for the Remote radio and/or its antenna
decrease the length of antenna cable

3.2 Check the Ethernet cable
If you connect a radio and the Ethernet LED does not light on the radio, there
may be a problem with the Ethernet cable. Verify that the cable is plugged into
the radio at one end, and to an Ethernet hub or a 10/100 Base-T Ethernet switch
at the other end. If using the PoE injector, verify that the M12 to RJ45 cable is
connected between the radio and the injector and also that the Ethernet patch
cable is connected between the injector and switch.
Note: The RLXIB-IHA radio auto-detects the Ethernet connection type, and does not require a
crossover cable for direct connection to a PC.
3.3 LED display
The RLXIB-IHA front panel includes a set of LEDs that indicate the radio’s status:

LED
Description
Signal Strength
If only one of these three LEDs is lit, then the radio is linked. If two LEDs are lit,
the radio’s signal strength is fair. If all three LEDs are lit, the signal strength is
good.
RadioLinx® 802.11a Industrial Hotspot User Manual
If a radio is configured as a master, the middle light of the three Signal Strength
LEDs will always be on, and the bottom Signal Strength LED will always be off.
The top LED on the master will flash if any radios are linked to this master.
After you first plug in the power cable and Ethernet cable to the radio, the
Power/Status LED should be green, meaning that the radio has power. If the
Ethernet LED is green, then the Ethernet connection is working. The RF Transmit
and RF Receive LEDs should blink.
All three LEDs will blink just after the radio links to the Master’s signal but before
it has been fully authenticated. Normally you will see this last only a few seconds.
If it lasts longer or never turns solid it usually means the encryption keys are not
correct.
3.4 Retrieve the default password
If you forget your password, you will be unable to change the radio settings. You
can retrieve the default password to use the software again, but you will lose all
the settings you programmed before. To retrieve the default password and return
the radio to its default settings, follow these steps:
1 Turn off power to the radio.
2 Locate the reset button hole, located to the left of the power connector.
3 Insert the end of a paperclip or similar device into the hole to press the reset
button.
4 Turn on power to the radio, and hold down the reset button for 30 seconds.
5 The radio will be reset to its default settings, including the password. You
should now be able to log in using the default password, which is "password".

3.5 Troubleshoot IH Browser error messages
One error message commonly occurs when you use the IH Browser, "Unable to
scan for AP's". You can easily remedy this error.
This error occurs when the IH Browser attempts to scan for radios and no valid
network connection exists on the PC, wired or wireless.
To correct this error, Confirm that your PC has at least one active network (LAN)
connection; it could be a wired Ethernet connection or a wireless 802.11
connection. One way to determine if your network connections are active is to
look in the system tray in the lower-right corner of your desktop. The two-PC icon
indicates a connection and the icon with a red X indicates an inactive connection.
If no connections are visible in the system tray, check Network Connections in
the Control Panel.
Confirm that the network connection has a valid IP address. Your network
connection might need to have a static IP address assigned to it. Check the IP

3.6 Troubleshoot missing radios
If radios are not visible in the IH Browser, try the following:
First, click the SCAN button again. Scans are sent as broadcast messages,
which can be dropped in RF connections, requiring the user to scan again.
Second, disable any software firewall running on your PC (This is most
common in Windows XP and newer). Open the NETWORK CONNECTIONS
folder in your Windows Control Panel, then open the LOCAL AREA
CONNECTION PROPERTIES window and verify that the check box under
INTERNET CONNECTION FIREWALL is not checked.
If the preceding approaches do not help, the PC running the IH Browser and
the radios are probably not connected to the same local network. Verify your
connections.
If you are in topological view, any unlinked radios may be at the bottom of the
window. Scroll down to see all radios. If you still cannot see radios with the IH
Browser, call technical support.

Parent Selection Parameters
Signal Strength Threshold
When the signal from a parent reaches a high enough value, a stronger
signal will not improve the quality of the link any further. For signals
that are above that threshold, only fewer hops from the Master give
preference. You can adjust that threshold here.
Rate to Parent
The default setting is auto which allows the radio to select the best rate
to use to the parent radio, and adapt over time. You might specify a
fixed rate rather than auto for example if the link to the parent has a low
signal strength in which case fixing a lower rate can improve
performance. The actual rate used between this radio and its parent is
the lower value of this setting and the Max Data Rate setting in the
parent (see Max Data Rate). So use these two controls in conjunction if
desired to tailor the rate of each parent link.

User Manual RadioLinx® 802.11a Industrial Hotspot
RLXIB-IHA radios support IGMP v1 and v2. The default operation of the RLXIBIHA radios is to have IGMP functionality enabled, although the user can disable
IGMP entirely. Additionally, the user can specify settings associated with IGMP
filtering and snooping. Unknown multicast addresses can be sent to all ports
(flood) or to none (filtered) by changing the IGMP Multicast Filtering option. The
user can specify whether the radio will generate IGMP queries, and configure the
query interval time.
By RFC specification, only one device on a network should generate IGMP
queries. As such, RLXIB-IHA radios will only send a query if another device has
not sent a query within its Query Interval setting, even if Query Generation is
enabled.
4.2.3 Rapid Spanning Tree Functionality
The software’s built-in Rapid Spanning Tree (RSTP) functionality enables you to
set up full redundancy between radios or other devices. Spanning Tree shuts off
ports as necessary to prevent loops. If loops are created in an Ethernet network,
packets can be circulated endlessly, consuming all the bandwidth and making
the network unusable.
RSTP allows users to create truly redundant connections between any two points
in the network. The radios detect the redundant paths and keep one connection
alive for communications. If the primary connection fails for any reason, the
secondary connection is quickly transitioned to a state to forward packets,
allowing the network to adapt itself to handle problems without customer
intervention.
RSTP uses active communications between network devices to propagate
changes in the network and to cause transitions to occur much more quickly.
Because RSTP is an IEEE standard, IH radios work in conjunction with wired
Ethernet switches to form a redundant network.
Page 52 of 123 ProSoft Technology, Inc.
July 25, 2013
RLXIB-IHA ♦ 802.11a Radio Configuration / Diagnostic Utility
RadioLinx® 802.11a Industrial Hotspot User Manual
Each RSTP device (RLXIB-IHA Radio or Ethernet switch) communicates with
other RSTP devices in the network via packets called Bridge Protocol Data Units
(BPDUs). BPDUs are sent out each of the devices ports. In a wired switch this
would be from each of the Ethernet ports. In an RLXIB-IHA Radio, in addition to
the Ethernet port, each wireless link is considered a port. These BPDUs are the
communications means to allow each RSTP device in the network to make sure
that the proper connections still exist.
In the following illustration, this RLXIB-IHA Radio has 4 RSTP "ports":
Ethernet port (1)
A port for its parent connection (2)
A port for each of its two child connections (11 and 12).
BPDUs are sent out the port at a rate called the "Hello Time". The accepted
standard value for this is 2 seconds. If a radio (or any other RSTP device) does
not get a BPDU for 2 Hello Times, it assumes the RSTP device that had been
there is no longer available. It can then open an alternate path if one is available.
This process is much like the STP process. If other devices on the network are
not operating in rapid spanning tree mode, the radio will revert to normal
spanning tree operation on a per-port basis.
RSTP provides a performance enhancement over STP operation. By
comparison, the radio using the STP algorithm would revert its port to the
listening state, and then to the learning state, before returning to the forwarding
state. Each of these states takes at least 15 seconds, during which the STP
devices are listening for BPDUs to re-negotiate the network topology. The
advantage of using the RSTP functionality is that is uses active handshaking
between adjacent RSTP devices to re-negotiate the network topology. This
process takes one to two seconds.

Description
Enable Spanning Tree
Spanning Tree is enabled when this box is checked. Without spanning
tree, redundant connections might exist if multiple radio links are
created in parallel with each other. Redundant connections are
blocked only if spanning tree is enabled. Additionally, spanning tree is
used to flush the Ethernet switch table when the network topology
changes as described in the section on Automatic Parent Selection.
Firmware versions 2.5xx and above for RLX-IH, and all versions of
RLXIB-IHA radios also support Rapid Spanning Tree (RSTP), and will
default to this mode when enabled.
The recommended setting for spanning tree is "Enabled".
Ethernet Edge Port
Because RSTP is an active protocol, it depends on communication
between RSTP devices. If no RSTP device is connected to the radio’s
Ethernet port, the handshake cannot take place. In this case RSTP
reverts to STP. This means that the Ethernet port will be forced to
adhere to the timer based transition protocol of STP.
Therefore on network transitions and power up, communications will
not be allowed over the Ethernet port for 30 to 45 seconds. This
setting is an indication that no redundant connections exist out this
port and communication can immediately be allowed. If for some
reason a BPDU is received on this port, the RSTP protocol will
negotiate properly and handle any possible redundant paths.
The recommended setting for Ethernet Edge Port is "Enabled".
User Manual RadioLinx® 802.11a Industrial Hotspot
Each RLXIB-IHA Radio contains a switch table, which tells it how to forward
Ethernet packets to get them to their proper destination. When the network
topology changes, the RLXIB-IHA Radio flushes its Ethernet switch table
immediately. This allows it to pass traffic immediately over the new network
topology and learn the configuration in the process. Until the learning is
complete, the packets are broadcast to their destination. As each packet is seen
and the switch table rebuilds, the radios return to directing packets to their
destinations.

The RSTP and STP algorithms use a cost to determine which
connections should be used. The "spanning tree" is formed by
determining the least cost paths from any RSTP device back to the
root.
Wireless
To give preference to a wired connection, set the Wireless cost to 200.
Ethernet
To give preference to a wired Ethernet connection, set the Ethernet
cost to 100.
RadioLinx® 802.11a Industrial Hotspot User Manual
You can define multiple master radios on the same network. Then, if one master
radio goes down, any radios linked to it can switch over to the other master, so
the networked radios remain connected and transmitting. In order to be
redundant, the two masters should typically be on the same segment—in other
words, they should be wired together into the same switch. These two masters
can be assigned different channels to increase network bandwidth, but they must
be assigned the same SSID.
Also, because all radios are repeaters, you can set up each radio to be able to
reach a master radio via multiple repeater paths. Then, if a repeater goes down,
the linked radios can use a different path to get back to a master radio.

Description
Max Data Rate
The maximum data transmission rate, in megabits per second, for this
radio. Available settings range from 1 to 54.
Max Basic Rate
In addition to the Data Rate setting which controls generic data traffic,
the Basic Rate setting adjusts the rate at which control packets such
as Beacons and Acks are sent at as well as packets that need to go to
the whole network such as Broadcasts. Because these packets are
intended for the whole network, the Max Basic Rate setting of the
Master is advertised to each of the radios in the network through
Beacons. Each radio, other than the Master, then inherits the Max
Basic Rate setting of the Master. Therefore the setting only needs to
be made in the Master radio. The setting in each of the other radios is
disregarded.
Immediate Broadcasting
Forward multicast traffic immediately, rather than waiting for specific
time intervals.
Block General Probe
Requests
Do not respond to general probe requests that are not specific to the
radio's SSID.
Range
The Range setting allows the radios to account for round trip delays.
The Range settings should be the same in all radios in the network
and should be at least large enough to account for the length of any
links. However, increasing the Range beyond what is necessary can
cause a slight decrease in throughput.

4.2.5 Advanced Settings
This configuration page opens when you click the Advanced Configuration button
on the Radio Configuration form.
It is important to allow many industrial protocols to communicate properly over
the RLXIB-IHA radios. The standard 802.11 AP operation for transmitting
broadcast messages is to accumulate them and transmit them only on specific
time intervals. This allows clients that are in power-save mode to wake up at the
synchronized time interval and receive the broadcast packets. However, the
power-save mode is rarely used in industrial networks. Additionally, many
industrial protocols utilize multicast traffic, which is sent as broadcast messages
over the wireless network. By enabling immediate broadcasting, these multicast
messages are not delayed by the wait for the next time interval to occur before
they can be transmitted. This results in improved network performance.
The settings on this form also allow you to configure the transmission rate and
broadcast mode to optimize this radio's use on an industrial network.

You can still connect clients to the "hidden" network by typing the

User Manual RadioLinx® 802.11a Industrial Hotspot
The following topics describe each security setting in more detail.
4.3.1 Encryption type
The preferred encryption type is WPA (WiFi Protected Access). You should only
select WEP (wired equivalency protocol) for use with an older client radio that
only has WEP encryption. For compatibility with clients that do not support WPA,
you can select WPA+WEP128 (bits) or WPA+WEP64 (bits) as the encryption
type. Then the older clients can connect to an access point using the WEP
setting, but new clients will use WPA and the RLXIB-IHA radios will still use WPA
among themselves.
IMPORTANT: If WPA+WEP is selected, some clients using WPA might not be able to connect
unless you use a WEP key other than number 1, due to limitations in these clients. In such cases,
you should set a WEP key other than key 1 and set this same key in all clients that are using WEP.
See WEP key (page 61).
WEP is the original security protocol used by 802.11 networks, but WPA offers
better protection against attacks, for several reasons: WPA distances the
encryption key from the actual data by performing several algorithms to the key
before generating the encrypted data, it performs dynamic key management by
changing keys frequently, and it performs message integrity checks to prevent
forgery and replay.
You can also select WEP 128, WEP 64, or None (no encryption) as the
encryption type, but none of these settings are recommended.
Note: If an RLXIB-IHA is set to use WPA+WEP, it will connect to other radios set to WPA only or
WPA+WEP, but it will not communicate with radios set to WEP only. Likewise, an RLXIB-IHA in
client mode with WPA+WEP selected will not connect to an access point with WEP only selected.
4.3.2 WPA phrase
To use WPA encryption on packets sent between the radios, enter a WPA pass
phrase of between eight and 63 normal keyboard characters. This phrase
automatically generates an encryption key of 128 hexadecimal characters. This
field is only available if you select WPA as the encryption type.
The default WPA-AES Phrase when a module ships is 'passphrase'.

4.3.3 WEP key
A key is a set of hexadecimal (hex) or ASCII characters used to encrypt data.
This field is only available if you select WEP as the encryption type. Write down
your WEP encryption key as you create it, because you must enter the same key
on your client.
To create a 64-bit WEP key, enter five normal text characters in the WEP key
field, which converts the characters automatically to 10 hex digits. Alternatively,
you can enter 10 hex digits (0 to 9, a to f, A to F) directly in the WEP key field. To
create a 128-bit key, enter 13 normal text characters, which convert to 26 hex
digits, or enter 26 hex digits (0 to 9, a to f, A to F) directly.
Note: Clients often support more than one WEP key. Packets received can be decrypted using any
one of the keys if programmed, but packets are always transmitted with the "default" WEP key
number. If you set a transmit key number on the RLXIB-IHA, make sure all other radios and clients
have this key programmed. To set keys other than key 1 on some clients using Windows, you
might have to use the Advanced settings.
Programming more than one key on the RLXIB-IHA requires setting the key
number to the key you want to program, entering the key, and saving your
changes. Repeat these steps for each key you want to program, saving after
each one; finally, change to the desired transmit key number if necessary and
save again (If "****" remains in the key field, the previously programmed key will
not be changed when changes are applied)

RadioLinx® 802.11a Industrial Hotspot User Manual
DHCP (Dynamic Host Control Protocol) is a service provided by a server
(typically a router or a firewall) on a local area network. Devices on a network
that supports DHCP can request and receive an IP address from the DHCP
server. RLXIB-IHA radios support DHCP; by default, they attempt to obtain an IP
address from a DHCP server.
If a DHCP server is not available, the radio will not be able to acquire an IP
address automatically, therefore you must assign an IP address, subnet mask
and default gateway to the radio so that it can communicate on the network.
You can also assign a Static (fixed or permanent) IP address to the radio to
make it easier to identify and configure the radio. Static IP addresses are
particularly useful when configuring radios to serve as Access Points, or for
radios that must be accessible through a firewall.

6.1 Product Overview
The RLXIB-IHA is an industrial high-speed Ethernet radio. You can use it in place
of Ethernet cables to save money, extend range, and make connections that may
not otherwise be feasible. The radio operates as a wireless Ethernet switch, so
any data that you can send over a wired network can also be sent over the radio.
The RLXIB-IHA is certified for unlicensed operation in the United States, Canada
and Europe at 5 GHz. With an output power of a 250mW (typical) approved highgain antennas, the radios can achieve distances of 5 miles line-of-sight between
them. You can use multiple repeaters to extend this range to far greater
distances.
You can develop a highly reliable wireless network by creating redundant (page
54) wireless paths. Multiple master radios can be installed without any special
programming or control. Repeater radios can connect to any master at any time;
if one master goes down, the repeater connects to another. Likewise, if a
repeater goes down, any repeater that was connected to it can reconnect to a
different repeater, keeping the network intact. You can create large, self-healing
tree-like networks in this fashion. Fully redundant paths are possible because the
Spanning Tree (page 54) protocol in the radios disables and enables paths as
necessary to avoid Ethernet loops, which would otherwise make your network
stop functioning.
In addition to acting as a switch, every master or repeater radio in an RLXIB-IHA
wireless network can simultaneously act as an 802.11a access point. This allows
802.11 WiFi clients to connect and roam between radios for monitoring of the
wireless network or general network access. The RLXIB-IHA has a special client
mode (page 25) that allows connection of any Ethernet device to any existing
802.11a access point, regardless of the brand (An example of an 802.11 client is
a laptop with a WLAN card).
Note: WiFi is a brand name originally issued by the WiFi Alliance, used to describe the underlying
technology of wireless_local area networks (WLAN) based on the IEEE 802.11 specifications.

A high level of security is inherent with AES (Advanced Encryption Standard)
encryption. You also can choose TKIP (Temporal Key Integrity Protocol), and if
necessary add WEP128 or WEP64 (Wired Equivalent Protocol) encryption in
addition to AES or TKIP for clients that do not support AES. A simple Media
Access Control (MAC) filter table restricts the radios or clients that can link to a
selected radio according to the MAC IDs you enter in the table.
The radio is designed for industrial applications with a metal enclosure, DIN-rail
mounting, and shock and vibration tested to IEC 60068.
The RLXIB-IHA is easy to use. Use the Radio Configuration / Diagnostic Utility,
which runs in your web browser, to configure the radio; optionally, you can use
an SNMP manager for configuration. The radio comes with a Windows-based
utility called RLX-IH Browser that finds all the radios on the network and lists
information about them. A topology view in the RLX-IH Browser shows how the
wireless network is linked together at any point in time. You can update firmware
at any time from anywhere on the network, even over the wireless link or over the
Internet.
ProSoft Technology radios can easily be installed into new or existing systems.
The software and manuals can be downloaded from the CD or ProSoft
Technology’s web site at www.prosoft-technology.com.
6.2 Radio hardware
The RLXIB-IHA radio consists of the following components:
1 One antenna port) (page 28)
2 LEDs (page 32) that indicate the status of the radio
3 Ethernet and serial cable ports (page 92, page 91)
4 Power connection
6.2.1 Radio power requirements
The RLXIB-IHA radio accepts voltages between 10 and 24 VDC, with an average
power draw of less than 9 watts. A detachable power connector comes with the
radio, as shown. The connector terminals are labeled + (positive DC connection)
and - (DC ground connection). You can use the provided AC-to-DC power supply
adapter that is pre-wired with a power connector, or you can use power from
another source, for example the power supply for the PLC or the networked
devices.
The DC power wires must be less than 3 m to meet regulatory requirements.

The RLXIB-IHA radio accepts 802.3af PoE, with an average power draw of less
than 9 watts. You can also order an optional DC PoE Injector if AC is not
available. The DC power wires must be less than 3 m to meet regulatory
requirements.
The radio shall be installed by trained personnel only, as outlined to the installation instructions
provided with each radio.
The equipment shall be installed by a qualified installer/electrician. The installer/electrician is
responsible for obtaining a secured ground connection between the lug terminal on the surge
protector to a verified common ground point using a minimum 6 AWG gauge wire. This must be
done when attaching power lines to the radio during installation.
A solid ground connection should be verified using a meter prior to applying
power to the radio. Failing to secure a proper ground could result in serious injury
or death as a result of a lightning strike.
Using Power over Ethernet (PoE) to power remote devices has several
advantages including:
"Carrier Class" Power Over Ethernet System.
Power can be supplied over long distances, up to 300 feet.
Power can be available wherever network access is available.
The power supply can be centrally located where it can be attached to an
uninterruptible power supply.
The user has the ability to easily power on reset the attached equipment from
a remote location.
There is no need to run additional power cabling to the device as power can
be supplied over the CAT5 Ethernet cable.
Used for remote mounted radios to save on cost of coax and reduce RF
losses.
Built-in Ethernet Surge protection to prevent equipment damage.
Overload and Short Circuit protection.
6.2.2 Ethernet Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs.
The Ethernet ports on the module are Auto-Sensing. You can use either a
standard Ethernet straight-through cable or a crossover cable when connecting
the module to an Ethernet hub, a 10/100 Base-T Ethernet switch, or directly to a
PC. The module will detect the cable type and use the appropriate pins to send
and receive Ethernet signals.
Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on a switch position. In this case, you must ensure
that the switch position and cable type agree.
Refer to Ethernet cable configuration (page 92) for a diagram of how to configure
Ethernet cable.

6.3 Antennas
When you are ready to connect antennas to the radio, see Connecting antennas
(page 28).
You must also consider three important electrical characteristics when selecting
antennas:
Antenna pattern (page 92)
Antenna gain (page 93)
Antenna polarity (page 93)
Antenna location, spacing, and mounting (page 96)
6.3.1 Antenna Pattern
Information between two wireless devices is transferred via electromagnetic
energy radiated by one antenna and received by another. The radiated power of
most antennas is not uniform in all directions and has varying intensities. The
radiated power in various directions is called the pattern of the antenna. Each
antenna should be mounted so that its direction of strongest radiation intensity
points toward the other antenna or antennas with which it will exchange signals.
Complete antenna patterns are three-dimensional, although often only a twodimensional slice of the pattern is shown when all the antennas of interest are
located in roughly the same horizontal plane, along the ground rather than above
or below one another.
A slice taken in a horizontal plane through the center (or looking down on the
pattern) is called the azimuth pattern. A view from the side reveals a vertical
plane slice called the elevation pattern.
Page 92 of 123 ProSoft Technology, Inc.
July 25, 2013
RLXIB-IHA ♦ 802.11a Reference
RadioLinx® 802.11a Industrial Hotspot User Manual
An antenna pattern with equal or nearly equal intensity in all directions is
omnidirectional. In two dimensions, an omnidirectional pattern appears as a
circle (in three dimensions, an omnidirectional antenna pattern would be a
sphere, but no antenna has true omnidirectional pattern in three dimensions). An
antenna is considered omnidirectional if one of its two dimensional patterns,
either azimuth or elevation pattern, is omnidirectional.
Beamwidth is an angular measurement of how strongly the power is
concentrated in a particular direction. Beamwidth is a three dimensional quantity
but can be broken into two-dimensional slices just like the antenna pattern. The
beamwidth of an omnidirectional pattern is 360 degrees because the power is
equal in all directions.
6.3.2 Antenna Gain
Antenna gain is a measure of how strongly an antenna radiates in its direction of
maximum radiation intensity compared to how strong the radiation would be if the
same power were applied to an antenna that radiated all of its power equally in
all directions. Using the antenna pattern, the gain is the distance to the furthest
point on the pattern from the origin. For an omnidirectional pattern, the gain is 1,
or equivalently 0 dB. The higher the antenna gain is, the narrower the
beamwidth, and vice versa.
The amount of power received by the receiving antenna is proportional to the
transmitter power multiplied by the transmit antenna gain, multiplied by the
receiving antenna gain. Therefore, the antenna gains and transmitting power can
be traded off. For example, doubling one antenna gain has the same effect as
doubling the transmitting power. Doubling both antenna gains has the same
effect as quadrupling the transmitting power.
6.3.3 Antenna Polarity
Antenna polarization refers to the direction in which the electromagnetic field
lines point as energy radiates away from the antenna. In general, the polarization
is elliptical. The simplest and most common form of this elliptical polarization is a
straight line, or linear polarization. Of the transmitted power that reaches the
receiving antenna, only the portion that has the same polarization as the
receiving antenna polarization is actually received. For example, if the
transmitting antenna polarization is pointed in the vertical direction (vertical
polarization, for short), and the receiving antenna also has vertical polarization,
the maximum amount of power possible will be received. On the other hand, if
the transmit antenna has vertical polarization and the receiving antenna has
horizontal polarization, no power should be received. If the two antennas have
linear polarizations oriented at 45° to each other, half of the possible maximum
power will be received.

6.3.4 Whip antennas
You can use a 1/2 wave straight whip or 1/2 wave articulating whip (2 dBi)
antenna with RLXIB-IHA radios. These antennas are the most common type in
use today. Such antennas are approximately 5 inches long, and are likely to be
connected to a client radio (connected directly to the radio enclosure). These
antennas do not require a ground plane. Articulating antennas and nonarticulating antennas work in the same way. An articulating antenna bends at the
connection.
6.3.5 Collinear array antennas
A collinear array antenna is typically composed of several linear antennas
stacked on top of each other. The more stacked elements it has, the longer it is,
and the more gain it has. It is fed in on one end.
The antenna pattern is torroidal. Its azimuthal beamwidth is 360°
(omnidirectional). Its vertical beamwidth depends on the number of
elements/length, where more elements equal narrower beamwidth. The antenna
gain also depends on the number of elements/length, where more elements
produce higher gain. Typical gain is 5 to 10 dBi.
The antenna polarity is linear, or parallel to the length of the antenna.

6.3.6 Yagi Array Antenna
A yagi antenna is composed of an array of linear elements, each parallel to one
another and attached perpendicular to and along the length of a metal boom. The
feed is attached to only one of the elements. Elements on one side of the fed
element are longer and act as reflectors; elements on the other side are shorter
and act as directors. This causes the antenna to radiate in a beam out of the end
with the shorter elements. The pattern depends on the overall geometry,
including the number of elements, element spacing, element length, and so on.
Sometimes the antenna is enclosed in a protective tube hiding the actual
antenna geometry.
The antenna pattern (page 92) is a beam pointed along the boom toward the end
with the shorter elements. The beamwidth varies with antenna geometry but
generally is proportional to the length (where longer length produces a narrower
beam).
The antenna gain (page 93) varies with antenna geometry but generally is
proportional to the length (where longer length produces higher gain). Typical
values are 6 to 15dBi.
The antenna polarity is Linear (parallel to the elements, perpendicular to the
boom).
Refer to the Antenna Types overview section for other types of approved
antennas.
6.3.7 Parabolic reflector antennas
A parabolic reflector antenna consists of a parabolic shaped dish and a feed
antenna located in front of the dish. Power is radiated from the feed antenna
toward the reflector. Due to the parabolic shape, the reflector concentrates the
radiation into a narrow pattern, resulting in a high- gain beam.
The antenna pattern is a beam pointed away from the concave side of the dish.
Beamwidth and antenna gain vary with the size of the reflector and the antenna
construction. Typical gain values are 15 to 30 dBi.

The antenna polarity depends on the feed antenna polarization.
6.3.8 Antenna location, spacing, and mounting
Consider the following points regarding antenna location, spacing, and mounting:
When placing antennas, ensure a clear line of sight between the master
radio's antenna and all of the other radio antennas.
If the site base contains obstructing terrain or structures, mount the antenna
on a tower or rooftop to provide a line-of-sight path. The line-of-sight
consideration becomes more important as the transmission path becomes
longer.
Mount the antennas as high off the ground as is practical. The higher an
antenna is above the ground, the greater its range.
Mount the antennas away from massive structures. Radio signals bounce off
metal walls, for example, which can compromise a clear signal.
Mount antennas to minimize the amount of nearby metal structures in the
antenna pattern.
Mount the antennas and install radios away from sources of RF interference.
Use the shortest possible antenna cable length. Signals lose power over the
cable's distance.
Choose antennas that are appropriate for the network's intended function.
If antennas are on radios on the same network, mount them so they have the
same polarity. If the antennas are on separate networks, mount them so they
have a different antenna polarity—for example, mount one antenna vertically
and the other horizontally.
Space radios at least three feet (one meter) apart so they do not overload
each other. If antennas must be near each other:
o Mount omnidirectional antennas directly above each other.
o Position directional antennas so they do not point at nearby antennas.
Place antennas side by side if they point in the same direction. Place
antennas back to back if they point in opposite directions.
