Parameter
Description
IGMP Query Interval
Specifies the number of seconds between queries (if the timer is not
pre-empted by a query from another device).
By RFC specification, only one device on a network should generate
IGMP queries. As such, the radio only sends an IGMP query if another
device has not sent a query within the radio's IGMP QUERY INTERVAL
setting, even if IGMP QUERY GENERATION is enabled.
Multicast State Count
Specifies the number of queries the radio generates before a device is
removed from the multicast group on this radio if no response is
received from the device.
4.6.2 STP Settings
You use the parameters in the STP SETTING group in the Radio Configuration /
Diagnostic Utility to specify the Spanning Tree Protocol parameters of your
RLX2-IHx series radio.

Parameter
Description
Enable Spanning Tree
Select this check box to enable Spanning Tree Protocol (STP).
If you enable Spanning Tree (recommended), the radio blocks
redundant connections. Additionally, the radio flushes the Ethernet
switch table when the network topology changes. See Rapid
Spanning Tree Functionality (page 103).
If you disable Spanning Tree (clear the check box), there can be
redundant connections if the radio creates multiple radio links in
parallel with each other. This also disables the other parameters in
the STP SETTINGS group.
All RLX2-IHx series radios support the Rapid Spanning Tree Protocol
(RSTP), and default to this mode when you enable Spanning Tree.
Ethernet Edge Port
Select this check box to enable the Ethernet Edge Port function
(recommended) when no RSTP device is connected to the Ethernet port.
This allows immediate communication through the Ethernet 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 is forced to adhere to
the timer based transition protocol of STP.
Therefore on network transitions and power up, communications are not
allowed over the Ethernet port for 30 to 45 seconds unless you enable
ETHERNET EDGE PORT. This setting specifies that no redundant
connections exist out the Ethernet port and communication can start
immediately. If for some reason the radio receives a BPDU (bridge
protocol data unit) on this port, the RSTP protocol negotiates properly
and handles any possible redundant paths.
Note: You can select ETHERNET EDGE PORT without selecting ENABLE
SPANNING TREE.
Bridge Times
Configures the timing intervals to use.
Priority
Determines which device is the root of the RSTP. The RSTP device with
the lowest priority becomes the root bridge.
The accepted standard value for this is 32768. If wired switches
exist in the network that support RSTP, they should always be
allowed to be the root.
For Master radios, set this value to 32769 to prevent the radio from
being the root over a wired switch.
For Repeater radios, set this value to 32770. This specifies that if
the network only has RLX2-IHx series radios, the Master radio
becomes the root.
Hello Time
Specifies the rate at which the radio sends out BPDUs. The
recommended industry standard is 2 seconds.
Max Age
Specifies the age limit for protocol information for a port.
The radio measures the age of the received protocol information
recorded for a port and discards it when the information's age limit
exceeds this value. The timeout value for this timer is the maximum age
parameter of the root.
Forward Delay
Specifies the timeout for time spent by a port in the learning and listening
states. The timeout value is the forward delay parameter of the root.
Path Costs
RSTP and STP algorithms use a cost to determine which connections
should be used in the Spanning Tree. The radio forms the Spanning
Tree by determining the lowest cost paths from any RSTP device back
to the root.

Rapid Spanning Tree Functionality
Rapid Spanning Tree Protocol (RSTP) is an advanced networking function that
shuts off ports as necessary to prevent data packet loops when more than one
network path is available. If loops exist in an Ethernet network, the devices can
circulate packets endlessly, consuming all the bandwidth and making the network
unusable.
RSTP allows the radios to create truly redundant connections between any two
points in the network, but use only one path at a time. The radios detect the
redundant paths and use only one primary connection for communications. If the
primary connection fails, the radios quickly change to the secondary connection
to a state to forward packets, allowing the network to adapt itself to handle
problems without requiring your intervention.
RTSP uses active communications between network devices to quickly
propagate changes and transitions in the network. Because RTSP is an IEEE
standard, RLX2-IHx series radios work in conjunction with wired Ethernet
switches to form a redundant network.
Each RSTP device (RLX2-IHx series radio or Ethernet switch) communicates
with other RSTP devices in the network using packets called Bridge Protocol
Data Units (BPDUs). Each device sends BPDUs out each of the devices ports. In
a wired switch, this is from each of the Ethernet ports. In an RLX2-IHx series
Radio, this is from both the Ethernet port and each wireless link. BPDUs allow
each RSTP device in the network to make sure that the proper connections still
exist.
The Port Status dialog box shows a list of all ports and their state. In the Radio
Configuration / Diagnostic Utility, on the BASIC SETTINGS tab, click PORT STATUS.
See Viewing the Radio Port Status (page 67). In this example, the RLX2-IHx
series 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)

User Manual Industrial Hotspots
Page 104 of 227 ProSoft Technology, Inc.
October 30, 2017
BPDUs are sent out the port at a rate called the Hello Time set in the Radio
Configuration / Diagnostic Utility on the ADVANCED NETWORK SETTINGS tab. The
accepted standard value for this parameter is 2 seconds. If a radio (or any other
RSTP device) does not get a BPDU from a device for a time period equal to two
Hello Times, the radio assumes the RSTP device is no longer available. The
radio can then open a redundant 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 reverts to normal Spanning Tree operation on the
ports connected to those devices.
RSTP provides a performance enhancement over STP.
A radio using the STP algorithm reverts 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.
A radio using the RSTP algorithm uses active handshaking between adjacent
RSTP devices to re-negotiate the network topology. This process takes only
one to two seconds.
Each RLX2-IHx series radio contains a switch table that tells the radio how to
forward Ethernet packets to get them to their correct destination. When the
network topology changes, the radio immediately flushes its Ethernet switch
table. This allows the radio to pass traffic immediately over the new network
topology and learn the configuration in the process. Until the radio completely
learns the new topology, it broadcasts the packets to their destination. As the
radios see each packet and rebuilds the Ethernet switch table, the radios return
to directing packets to their destinations.

The RLX2-IHx series radio's SNMP agent supports SNMP protocol version
1.4 and 2.
MIBs:
o RFC12133-MIB (partial; internet.mgmt.MIB-2.system, .interfaces, .snmp)
o ROMAP-MIB (internet.private.enterprises.romap)
It also supports a selection of standard SNMP traps, including Cold Start,
which the radio sends when it initializes.
4.6.4 Cable Break Detection
One common application interconnects a line of RLX2-IHx Masters with
Radiating Cable, allowing mobile platforms to move down the line roaming from
Master to Master. The radiating cable between the Masters allows them to
receive each other's packets, in particular each other's Beacon frames. It is
therefore possible for a Master to detect if the Radiating Cable between itself and
the next or previous Master is broken or damaged. When enabled, this feature
will produce an SNMP Trap whenever it detects an RSSI drop to one of its
Monitored Peers.
A cable break is defined as a change in RSSI greater than the Cable Break
Threshold. The RLX2-IHx will automatically determine the closest Peers and will
adopt a baseline RSSI from each Peer when it is first picked to be monitored.

4.9 Configuring VLAN Settings
You use the VLAN tab in the Radio Configuration / Diagnostic Utility to specify
the Virtual Local Area Network parameters of a RLX2-IHx series radio. When the
radio sends a packet, it includes the selected VLAN packet ID.
RLX2-IHx series radios support port based VLANs. Each RLX2-IHx series radio
can be considered to have 3 different ports or interfaces; the Ethernet interface,
the local applications stack of the radio itself, and the 802.11 BSS created by
each radio, allowing client devices to associate. You can configure the VLAN
settings for the Ethernet interface on all RLX2-IHx series radios. You can
configure the VLAN for the Local and SSID ports on the Master radio. The
Master radio pushes these settings to each connected Repeater radio. This
allows the VLAN settings for a bridged network rooted at a Master radio to have
common settings for these two ports. This ensures, for example, that if the Local
interface is set to a management VLAN, the all Repeater radios are accessible
from a Management PC. For more information, see Appendix D - RLX2-IHx
series Virtual LAN (VLAN) Functionality (page 175).
You can think of the Ethernet ports for the Master radio and its associated
Repeater radios as a smart switch. Transporting tagged frames to the
appropriate remote Ethernet port is automatic and does not require any settings.

Find missing radios
6.1 Checking the Ethernet Cable
If the radio’s Ethernet port is connected to a PC or network, 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,
a PC, or a 10/100/1000 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 the switch.
Note: The RLX2-IHx series radio auto-detects the Ethernet connection type, and does not require
a crossover cable for direct connection to a PC.
6.2 LED Display
The RLX2-IHx series radio front panel includes a set of LEDs that indicate the
radio’s status.
LED
Description
POWER
Booting up
Fully operational
This two-color LED turns amber when power is first applied. After power is applied, this
LED goes out completely for about four seconds while the internal hardware is initialized.
After initialization the power LED turns green, indicating the radio is fully operational.
RF
TRANSMIT
Transmitting data over the wireless interface
RF RECEIVE
Receiving data over the wireless interface
SERIAL
Receiving serial data
ETHERNET
Transmitting Ethernet data over the wireless interface
Note that the state of the front-panel ETHERNET LED may not necessarily correspond to
the state of the DATA LED on the Ethernet connector. The DATA LED on the Ethernet
connector indicates traffic over the wired link, while the ETHERNET LED indicates network
data sent or received through the wireless link.
For example, if the radio is pinged over the wired link, the DATA LED on the Ethernet
connector blinks but the ETHERNET LED does not (because the ping packet was not
transmitted over the air).
NET
Blinks if SD card with new configuration inserted. Reserved for future additional use.

Radio linked, Good Signal
The following LEDs should light when you connect the power and Ethernet
cables to the radio.
The POWER LED should turn green.
The SPEED LED on the Ethernet connector should indicate a valid wired link.
This LED is located at the top of the Ethernet RJ-45 connector and is marked
SPEED
o OFF = 10 MB
o ON = 100 MB
o BLINK = 1GB.
The RF TRANSMIT and RF RECEIVE LEDs should start to blink
occasionally.
For radios in Repeater or Client mode, all three SIGNAL STRENGTH LEDs blink
just after the radio links to the Master radio but before fully authenticating the link.
Normally this lasts only a few seconds. If the SIGNAL STRENGTH LEDs blink for
longer than a few seconds, or do not stop blinking, it usually means the
encryption keys are not correct. The Wireless Security Settings on a Repeater
radio must match those on the Master radio. See Configuring a Radio - Getting
Started (page 44).

6.4 Unable to scan for AP's error message
The Unable to scan for AP's error message may appear in the IH Browser when
it attempts to scan for radios and no valid network connection exists on the PC
(wired or wireless).
To correct this error
1 Confirm that the PC has at least one active network (LAN) connection. It
could be a wired Ethernet connection or a wireless 802.11 connection.
2 Confirm that the network connection has a valid IP address. The network
connection might need to have a static IP address assigned to it. Check the
IP address of the network connection to determine that one has been
assigned.

6.5 Finding Missing Radios
If the radios are not visible in the IH Browser, try the following:
1 Refresh the IH Browser display. See Refreshing the Display in the IH
Browser (page 42). The IH Browser sends scans as broadcast messages,
which can be dropped in RF connections, requiring that you repeat the scan.
2 Disable any software firewall running on the PC (This is most common in
Windows XP and newer). Open the Network connections folder in the
Windows Control Panel, then open the Local Area Connection Properties
window and verify that the check box under INTERNET CONNECTION FIREWALL
is not checked.
3 If these steps do not help, verify that the PC running the IH Browser and the
radios are connected to the same local network.
4 In the IH Browser, change to the Topology view. From the VIEW menu, click
TOPOLOGY VIEW. Any unlinked radios may appear at the bottom of the
window. Scroll down to see all the unlinked radios. If you still cannot see the
radios in the IH Browser, call ProSoft Technology Technical Support. See

8.2 Radio Power Requirements (All other radios)
Note: The following instructions do not pertain to the RLX2-IHNF-W radio.
The RLX2-IHx series radios accept voltages between 10 and 24 VDC, with an
average power draw of less than 8 Watts. A detachable power connector comes
with the radio, as shown below. The connector terminals are labeled + (positive
DC connection) and - (DC ground connection).
You can use the AC-to-DC power supply adapter supplied with the optional RLX-
IHBTK Bench Test Kit to convert the input power. The DC power wires must be
less than 3 meters in length to meet regulatory requirements.
Warning: When wiring the power connector supplied with the radio, be sure to observe the proper
polarity markings on the power connector. Wiring the connector incorrectly can cause serious
damage to the radio which is not covered under the ProSoft Technology warranty.
The power connector (ProSoft Technology part number 002-0116) is shown on
the left in the photo above. Note the + and – polarity markings. The wire
installation tool (ProSoft part number 357-0061) shown on the right is helpful for
installing wires into the spring-loaded contacts inside power connector.

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.

Danger: 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:
"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 un-
interruptible power supply.
You can easily power or 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, CAT5E, or CAT6 Ethernet cable.
You can save on the cost of coax cable and reduce RF losses for remote
mounted radios.
Built-in Ethernet surge protection to prevent equipment damage.
Overload and short circuit protection.
8.3 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 when running at 10 MBit or 100 MBit
speeds. All eight wires are used when running at 1000 MBit speeds.
Category 5e or better cable is recommended for 1000 MBit speeds.
The Ethernet port on the module is Auto-Sensing. Use either a standard
Ethernet straight-through cable or a crossover cable when connecting the
module to an Ethernet hub, a 10/100/1000 Base-T Ethernet switch, or directly
to a PC. The module detects the cable type and uses the appropriate pins to
send and receive Ethernet signals.
Ethernet cabling is similar to 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,
ensure the switch position and cable type agree.
Refer to Ethernet Cable Configuration (page 168) for a diagram of how to
configure Ethernet cables.

Support
In This Chapter
DFS Radio Operations ........................................................................ 171
Some channels in the 5 GHz band are shared with radar and must adhere to
Dynamic Frequency Selection (DFS) rules. If the radio detects the presence of
radar on its operating frequency, it must automatically change to another
frequency.
Note: This applies only to radios that can operate at frequencies in the 5 GHz band.
9.1 DFS Radio Operations
If radar is detected on an operating channel, transmissions must cease within the
required Channel Closing Transmission Time, and must move to a new channel
within the required Channel Move Time. Before transmitting on a new DFS
channel that has not been previously checked for radar, the RLX2-IHx series
radio must monitor the channel for the Channel Availability Check Time before
transmitting. Operations cannot return to a channel where radar was detected for
at least the Non-Occupancy Period. The values for these parameters are noted
in the table below:

If a Master radio detects radar, it issues a channel change announcement to all
Client and Repeater radios in the network. It then moves to a new channel within
the Channel Move Time. (Typically, this move time is 500 milliseconds or less.) If
the selected channel was not previously checked for the presence of radar, the
Master radio must do so for the Channel Availability Check Time before it can
begin to transmit. If the newly-selected channel is not a DFS channel, or if the
channel was previously monitored for radar since the radio was powered on,
transmissions can begin immediately.
During the Channel Availability Check Time, a radio blinks all three amber Signal
Strength LEDS approximately once per second. If radar is detected on the new
channel during the Channel Availability Check Time, the Master radio selects
another channel and begins the process again.
If a Client or Repeater radio detects radar, in addition to stopping data
transmission, must notify its parent of the presence of radar. Each unit receiving
a radar notification from a child unit treats it the same as if it had detected radar
itself and acts accordingly. Thus radar notifications always reach the Master
radio which causes a channel change order to be issued.
After a Master radio successfully selects a DFS channel, Repeater or Client
radios connect to the Master and scan for radar for an additional 60 seconds
(Channel Availability Check Time). If a chain of Repeater radios ultimately
connects to a Master radio using a DFS channel, the time to connect is 60
seconds for each Repeater radio in the chain as DFS channels are initially
scanned for radar transmissions.
9.1.1 Selecting a DFS 5 GHz Channel
For [ModelNumber] Master radios operating in the 5 GHz band, you can select a
DFS channel, or let the radio automatically select the DFS channel. DFS
channels are a 5 GHz radio parameter only, and apply to all RLX2-IHx series
radios except the RLX2-IHG.
Note: In some cases, the radio may select a channel in the 5 GHz Upper Band if it does not find an
open channel in the 5 GHz DFS Band.

Virtual Local Area Networks (VLANs) are typically used to segment core network
components and network access rules. A VLAN provides the equivalent of a
wired patch panel through software (packet filtering) rather than hardware
(physical wires).
Constraining data to a particular Virtual LAN requires that the radio tag packets
with a VLAN identifier. VLAN tagging simply adds extra information in the packet
header of Ethernet frames so VLAN-enabled switches know how to pass along
the data.
The RLX2-IHx series radios (version 33 and later) provide:

You can get diagnostic and status information from the RLX2-IHx series radio by
querying the radio using either the Ethernet/IP or Modbus TCP/IP protocols.
11.1 Modbus TCP/IP Server Support
You can use a Modbus TCP/IP client to poll the RLX2-IHx series radio for
diagnostic and status information. The Modbus TCP/IP server in the radio
monitors port 502 and port 2000, and responds to requests from the port eth0
(Ethernet port) or ppp0 (Point-to-Point Protocol). PPP is a data link layer protocol
that establishes a connection between two nodes.
The radio supports up to five concurrent Modbus TCP/IP client connections.

13.1.2 Antenna Pattern
Wireless devices transfer Information using electromagnetic energy radiated by
one antenna and received by another antenna. The power radiated by most
antennas is not uniform in all directions and has varying intensities. The power
radiated by the antenna in various directions is called the pattern of the antenna.
Mount each antenna so that the direction of strongest radiation points toward the
other antenna or antennas with which it will exchange signals.
Complete antenna patterns are three-dimensional. Often only a two-dimensional
slice of the pattern is shown when all the antennas of interest are located in
roughly the same horizontal plane instead of above or below one another. A slice
taken in a horizontal plane through the center (or looking down onto the pattern)
is called the azimuth pattern. A slice taken in a vertical plan from the side is
called the elevation pattern.
Appendix G - Antenna Configuration RLX2-IHx series ♦ 802.11a, b, g, n
User Manual Industrial Hotspots
Page 188 of 227 ProSoft Technology, Inc.
October 30, 2017
An antenna pattern with equal or nearly equal intensity in all directions is called
omnidirectional. In two dimensions, an omnidirectional pattern appears as a
circle (in three dimensions, an omnidirectional antenna pattern is a sphere, but
no antenna has a 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.
13.1.3 Antenna Gain
Antenna gain is a measure of how strongly an antenna radiates in its direction of
maximum intensity compared to the strength of the radiation if the same power
were applied to an omnidirectional antenna (one that radiated all of its power
equally in all directions). In 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, 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, you can make trade-offs between the
antennas' gain and transmitting power. For example, doubling the gain of one of
the antennas has the same effect as doubling the transmitting power. Doubling
the gain for both antennas has the same effect as quadrupling the transmitting
power.
13.1.4 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.
An antenna only receives the portion of the transmitted power that has the same
polarization as the receiving antenna polarization. For example:
If the transmitting antenna polarization is in the vertical direction (vertical
polarization), and the receiving antenna also has vertical polarization, the
maximum amount of power possible is 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, only
half of the possible maximum power is received.

13.2 Antenna Types
Antenna types used with a RLX2-IHx series radio include whip, collinear array,
yagi array, and parabolic reflector. See the RLX2-IHx series Approved Antennas
(page 191) section for other types of approved antennas.
13.2.1 Whip Antennas
For RLX2-IHx series radios, use a 1/2 wave straight whip antennal or a 1/2 wave
articulating whip (2 dBi) antenna. These antennas are the most common type in
use today.
They are approximately 5 inches long, and are likely to be connected directly
to the client radio enclosure.
These antennas do not require a ground plane.
Articulating antennas and non-articulating antennas work in the same way.
An articulating antenna bends at the connection as shown in the image
below.
13.2.2 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. The signal is connected at one end.

The antenna pattern is torroidal. Its azimuthal beamwidth is 360°
(omnidirectional). Its vertical beamwidth depends on the number of
elements/length, and more elements produce a narrower beamwidth.
The antenna gain also depends on the number of elements/length, and more
elements produce a higher gain. The typical gain for this antenna is 5 to 10
dBi.
The antenna polarity is linear, or parallel to the length of the antenna.
13.2.3 Yagi Array Antenna
A yagi array 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 signal is connected to only one of the elements. Elements on one
side of the connected 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 (as shown in the image below).
The antenna pattern 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 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).

13.2.4 Parabolic Reflector Antennas
A parabolic reflector antenna consists of a parabolic shaped dish and a feed
antenna located in front of the dish. The feel antenna radiates power toward the
reflector. Due to the parabolic shape, the reflector concentrates the radiation into
a narrow pattern, resulting in a beam with high gain.
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.
13.3 RLX2-IHx series Approved Antennas
If you are located In the U.S. and Canada, use antennas that are specifically
approved by the U.S. Federal Communications Commission (FCC) and Industry
Canada for use with the RLX2-IHx series radios. Contact ProSoft Technology or
visit www.prosoft-technology.com for a current list of approved antennas.
Antenna selection depends on whether the bi-directional amplifier is being used
or not. For each approved antenna, there is a specified minimum distance the
antennas must be separated from users for safe exposure limits, according to
FCC part 2.1091.

13.4 Antenna Location, Spacing, and Mounting
Consider the following points regarding RLX2-IHx series radio 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 contains obstructing terrain or structures, mount the antenna on a
tower or rooftop to provide a line-of-sight path. This line-of-sight consideration
becomes more important as the transmission path becomes longer.
Mount the antennas as high off the ground as is practical for greater range.
Mount the antennas away from massive structures. For example, radio
signals bounce off metal walls, which can compromise a clear signal.
Mount the antennas and install radios away from sources of RF interference.
Use the shortest possible antenna cable length. Signals lose power over the
length of the cable.
Choose antennas that are appropriate for the network's intended function.
If antennas are on radios on the same network, mount them with matching
polarity. If the antennas are on separate networks, mount them with 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 radio 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.

15 Appendix I - Compatibility with ProSoft RLXIB
Series Radios
The RLX2-IHx series radios are 100% functionally compatible with ProSoft’s
legacy RLXIB-IHA, RLXIB-IHG, and RLXIB-IHW radio models. This allows
customers with RLXIB series radios to add RLX2-IHx series radios to their
existing networks without any reconfiguration of existing assets or problems with
obsolescence. The main differences in the RLX2-IHx series radios are the
following improvements:
Different enclosure size for more efficient heat dissipation
Faster, more efficient electronics that consume less power
Gigabit Ethernet
MicroSD memory cards for configuration data storage
Internal temperature sensor
The RLX2-IHx series radios will acquire additional functionality as new firmware
features are added. These new features will not be added to the RLXIB radios,
but the RLX2-IHx series radios will continue to work with RLXIB radios using their
existing functionality.
The RLX2-IHNF is an 802.11n device that does not have an RLXIB series
equivalent. It cannot function as a Repeater or Master radio to ProSoft’s RLXIB-
IHxN series radio products. Specific differences by product are noted in the
following table. Specifications that have not changed between the RLXIB and
RLX2-IHx series radio products are not listed.

Symbols & Numeric
802.11
A group of wireless specifications developed by the IEEE. It details a wireless
interface between devices to transport packet traffic.
802.11a
Operates in the 5 GHz frequency range with a maximum 54 Mbit/sec signaling
rate.
802.11b
Operates in the most commonly used 2.4 GHz Industrial, Scientific, and
Measurement (ISM) band. Provides signaling rates of up to 11 Mbit/sec using
CCK modulation.
802.11g
Similar to 802.11b but supports signaling rates of up to 54 Mbit/sec using OFDM
modulation. Operates in the heavily used 2.4 GHz ISM band.
802.11i
Sometimes called Wi-Fi Protected Access 2 (WPA 2). WPA 2 exclusively uses
the 128-bit and above Advanced Encryption Standard (AES), along with 802.1x
authentication and key management features.
802.11n
Uses higher modulation rates and packet aggregation to raise effective WLAN
throughput to more than 100 Mbit/sec.
A
Access Point
A generic term for an 802.11 radio that "attaches" other 802.11 (clients) to a
wired network. Some access points (APs) can also bridge to other APs.
Ad hoc Mode
Wireless network framework in which devices can communicate directly with one
another without using an accesspoint or a connection to a regular network.
RLX2-IHx series radio products do not support Ad hoc mode.
AES
Advanced Encryption Standard. New standard for encryption adopted by the U.S.
government for secure communications.
Amplifier
A device connected to an antenna that increases the signal strength and
amplifies weak incoming signals.

Antenna
A device connected to a wireless transceiver that concentrates transmitted and
received radio waves to increase signal strength and thus the effective range of a
wireless network.
ASCII
American Standard Code for Information Interchange. A communication mode in
which each eight-bit byte in a message contains one ASCII character code.
ASCII characters (or hexadecimal characters) are sometimes used as a key to
encrypt data and ensure its secure transmission.
Association
Process whereby two 802.11 radios establish communications with each other.
Requirements for communication include the same SSID (network names) and
encryption settings.
Authenticate
The process of confirming the identity of someone connecting to a network.
Authentication Server
A back-end database server that confirms the identity of a supplicant to an
authenticator in an 802.1x-authenticated network.
B
Band
Another term for spectrum used to indicate a particular set of frequencies.
Wireless networking protocols work in either the 2.4 GHz or the 5 GHz bands.
Bandwidth
(see Throughput)
Bridging Client, Radio Mode
A radio in Bridging Client mode can connect to any Access Point, and can
support one multiple Ethernet device but can only bridge IP-based traffic. See
also Repeater, Radio Mode.
C
CACT
CACT is an acronym for Channel Availability Check Time, a parameter used in
DFS channel selection. During DFS when a radio changes channels, it must
listen for the CACT on the new channel before beginning operations. For most
channels the CACT is 60 seconds.
Channel
One portion of the available radio spectrum that all devices on a wireless network
use to communicate. Changing the channel on the access point/router can help
reduce interference.

Decibel (dB)
A measure of the ratio between two signal levels; used to express gain (or loss)
in a system.
Default Gateway
The IP address of a network router where data is sent if the destination IP
address is outside the local subnet. The gateway is the device that routes the
traffic from the local area network to other networks such as the Internet.
Device-to-Device Network (Peer-to-Peer Network)
Two or more devices that connect using wireless network devices without the
use of a centralized wireless access point. Also known as a peer-to-peer
network.
DFS
DFS stands for Dynamic Frequency Selection, a requirement for operation on
certain frequencies in the 5 GHz band in many countries. When a radio operates
on a DFS frequency, it must sense the presence of radar and automatically
change to another channel if radar is detected.
DHCP
The dynamic host configuration protocol is an Internet protocol, similar to BootP,
for automating the configuration of computers that use TCP/IP. DHCP can be
used to automatically assign IP addresses, to deliver IP stack configuration
parameters, such as the subnet mask and default router, and to provide other
configuration information, such as the addresses for printer, time, and news
servers.
Direct Sequence Spread Spectrum
A modulation mechanism that spreads the signal for a wide band, allowing
reception even for overlapping data signals. 802.11b uses DSSS modulation.
Directional Antenna
Transmits and receives radio waves in a single direction.
Diversity Antenna
An antenna system that uses multiple antennas to reduce interference and
maximize reception and transmission quality.

have to be emitted by an isotropic antenna (that evenly distributes power in all
directions and is a theoretical construct) to produce the peak power density
observed in the direction of maximum antenna gain.
Encryption
Method of scrambling data so that only the intended viewers can decipher and
understand it.
F
Firmware
Firmware is the embedded software code that that runs in hardware containing a
CPU (similar to the BIOS in a personal computer). This is distinguished from the
IH Browser software that is installed on the Configuration PC.
Fresnel Zone
An elliptical area on either side of the straight line of sight that must also be clear
for a long-range wireless network to work.
Full-Duplex
A communications circuit or system designed to simultaneously transmit and
receive two different streams of data. Telephones are an example of a full-duplex
communication system. Both parties on a telephone conversation can talk and
listen at the same time. If both talk at the same time, their two signals are not
corrupted.
G
Gain, Antenna
The amount by which an antenna concentrates signal strength in a wireless
network.
Gateway
In wireless terms, a gateway is an access point with additional software
capabilities such as providing NAT and DHCP and access to a Wide Area

Guard Interval (GI)
An interval of time between data symbols during transmission. The guard interval
time for 802.11a/b/g systems is fixed at 800 microseconds. 802.11n devices can
also use a 400 microsecond guard interval, falling back to 800 microseconds if
excessive data corruption is detected.
H
Half-Duplex
A communications circuit or system designed to transmit and receive data, but
not both simultaneously. CB or walkie-talkie radios are an example of a half-
duplex communication system. Either parties on a radio conversation may talk or
listen; but both cannot talk at the same time without corrupting each other's
signal. If one operator is sending, the other must be receiving to have successful
communication.
Hz
Hertz. The international unit for measuring frequency equivalent to the older unit
of cycles per second. One megahertz (MHz) is one million hertz. One gigahertz
(GHz) is one billion hertz. The standard US electrical power frequency is 60 Hz.
802.11a devices operate in the 5 GHz band; 802.11b and g devices operate in
the 2.4 GHz band.
I
IEEE
Institute of Electrical and Electronics Engineers, Inc. IEEE is a professional
organization with members in over 175 countries and is an authority in technical
areas such as computer engineering and telecommunications. IEEE developed
the 802.11 specifications.
IP Address
A 32-bit identification number for each node on an Internet Protocol network.
These addresses are represented as four sets of 8-bit numbers (numbers from 0
to 255), separated by periods ("dots").
Networks using the TCP/IP protocol route messages based on the IP address of
the destination. Each number can be 0 to 255. For example, 192.168.0.100 could
be an IP address. Each node on the network must have a unique IP address.
K
Key
A set of information (often from 40 to as much as 256 bits in size) that is used as
a seed to an encryption algorithm to encrypt (scramble) data. Ideally, the key
must also be known by the receiver to decrypt the data.

LAN
Local Area Network. A system of connecting PCs and other devices within the
same physical proximity for sharing resources such as internet connections,
printers, files, and drives. When Wi-Fi is used to connect the devices, the system
is known as a wireless LAN or WLAN.
LED
Light-emitting diode.
Line of Sight (LoS)

M
MAC ID
Media Access Control address. Every device has its own MAC address which is
a unique identifier used to unambiguously identify the source and destination of
any packet on the network.
Mbps
Megabits per second, or a million bits per second. A measure of data rate.
Megahertz
A measure of electromagnetic wave frequency equal to one million hertz. Often
abbreviated as MHz and used to specify the radio frequency used by wireless
devices.
MIC
Message Integrity Check. One of the elements added to the TKIP standard. A
signature is added by each radio on each packet it transmits. The signature is
based on the data in the packet, a 64-bit value (key) and the MAC address of the
sender. The MIC allows the receiving radio to verify (check) that the data is not
forged or altered.
MIMO
Multiple Input Multiple Output refers to using multiple antennas in a Wi-Fi device
to improve performance and throughput. MIMO technology takes advantage of a
characteristic called multipath, which occurs when a radio transmission starts out
at Point A and the reflects off or passes through surfaces or objects before
arriving, via multiple paths, at Point B. MIMO technology uses multiple antennas
to collect and organize signals arriving via these paths.
Modbus
The Modbus protocol provides the internal standard that the MODICON®
controllers use for parsing messages. During communications on a Modbus
network, the protocol determines how each controller knows its device address,
recognizes a message addressed to it, determines the kind of action to be taken,
and extracts any data or other information contained in the message. If a reply is
required, the controller constructs the reply message and sends it using Modbus
protocol.

performed by a radio frequency engineer and used by systems integrators to
identify the optimum placement of access points to ensure that planned levels of
service are met. Site surveys are sometimes conducted following the deployment
to ensure that the WLAN is achieving the necessary level of coverage. Site
surveys can also be used to detect rogue access points.
Spectrum
A range of electromagnetic frequencies.
Spread Spectrum
A form of wireless communication in which a signal’s frequency is deliberately
varied. This increases bandwidth and lessens the chances of interruption or
interception of the transmitted signal.
SSID
Service Set Identifier is a sequence of characters unique to a specific network or
network segment that’s used by the network and all attached devices to identify
themselves and allow devices to connect to the correct network when one or
more than one independent network is operating in nearby areas.
Subnet Mask
A mask used to determine what subnet an IP address belongs to. An IP address
has two components: the network address, and the host (node or device)
address; for example the IP address 150.215.017.009. Assuming this is part of a
Class B network (with a subnet mask of 255.255.0.0), the first two numbers
(150.215) represent the Class B network address, and the second two numbers
(017.009) identify a particular host on this network.
T
TKIP
Temporal Key Integrity Protocol. A wireless security encryption mechanism in Wi-
Fi Protected Access (WPA).
U
UART
Universal Asynchronous Receiver/Transmitter
W
WDS
Wireless Distribution System. Enables access points to communicate with one
another in order to extend the range of a wireless networks. Used in 802.11g
based access points.

WEP
Wired-Equivalent Privacy protocol was specified in the original IEEE 802.11
standard to provide a WLAN with a minimal level of security and privacy
comparable to a typical wired LAN, using data encryption.
Wi-Fi
A certification mark managed by a trade group called the Wi-Fi Alliance. Wi-Fi
certification encompasses numerous standards including 802.11a, 802.11b,
802.11g, WPA, and more. Equipment must pass compatibility testing to receive
the Wi-Fi mark.
Wi-Fi CERTIFIED™
The certification standard designating IEEE 802.11-based wireless local area
network (WLAN) products that have passed interoperability testing requirements
developed and governed by the Wi-Fi alliance.
Wi-Fi Interoperability Certificate
A statement that a product has passed interoperability testing and will work with
other Wi-Fi CERTIFIED products.
Wi-Fi Protected Setup
Wi-Fi Protected Setup™ (previously called Wi-Fi Simple Config) is an optional
certification program developed by the Wi-Fi alliance designed to ease set up of
security enabled Wi-Fi networks in the home and small office environment. Wi-Fi
Protected Setup supports methods (pushing a button or entering a PIN into a
wizard-type application) that are familiar to most consumers to configure a
network and enable security.
Wireless Gateway
A term used to differentiate between an access point and a more-capable device
that can share an internet connection, serve DHCP, and bridge between wired
and wireless networks.
Wireless Network
A network of connected using a centralized wireless access point.
WLAN
Wireless Local Area Network. A type of local area network in which data is sent
and received via high-frequency radio waves rather than cables or wires.
WPA
Wi-Fi Protected Access is a data encryption specification for 802.11 wireless
networks that replaces the weaker WEP. It improves on WEP by using dynamic
keys, Extensible Authentication Protocol to secure network access, and an
encryption method called Temporal Key Integrity Protocol (TKIP) to secure data
transmissions.
WPA2
An enhanced version of WPA. It is the official 802.11i standard. It uses Advanced
Encryption Standard instead of TKIP. AES supports 128-bit, 192-bit, and 256-bit
encryption keys.
