OS2400 Radio Module
Exhibit 21: User Manual 3
FCC ID: OQ7OS2400
Product Overview
Summary of Function and Use
The OS2400s radios have been designed to provide a wireless replacement for any
serial cable. Any two devices which could otherwise function together with a physical
serial cable between them can be incorporated into a wireless network and continue to
function as before.
Spread spectrum: These radios transmit using a technique known as “spread
spectrum, frequency hopping communications”. Using the spread spectrum technique a
narrow band signal is spread over a broader portion of the radio frequency band.
Frequency hopping: A radio which rapidly changes its operating frequency several
times per second following a pre-determined sequence of frequencies is defined as
“frequency hopping”. The receiving and transmitting radios are programmed to follow
the same frequency hopping sequence.
The OverAir design takes advantage of these characteristics which are inherent to the
spread spectrum technique:
? ? increased immunity to noise. Radios are designed to detect specific radio
frequencies. “Noise”is defined as an unwanted signal which has been
transmitted at the same frequency as the radio was designed to detect. There
are many man-made and natural sources of “noise”. Due to the spread spectrum
and frequency hopping techniques, the OS2400 operates more efficiently than a
radio which operates using conventional technology.
? ? multiple users can share the same frequency at the same time. As an example
of this, cellphone use is dependent upon spread spectrum transmission.
Under FCC rules, users of FCC certified spread spectrum products do not require their
own license from the FCC. The manufacturers of the products are required to apply for
and be granted an FCC license for the device. OverAir has been granted a license by
the FCC for the use of its OS2400 radios.

FCC ID: OQ7OS2400
Approved Antennas
It is important to keep the radio’s antenna a safe distance from the user. In order to
meet the requirements of FCC part 2.1091 for radio frequency radiation exposure, this
module must be used in such a way as to guarantee at least 20 cm between the antenna
and the body, or more for high gain antennas. The FCC requires a minimum distance
from the user of 1mW cm2 squared power density”or 20cm, whichever is the greater
distance.
If a specific application requires a proximity of less than 20cm, the application must be
approved through the FCC for compliance to part 2.1093.

Max Antenna Gain / Output Power
NOTE:
All of the Locus, Inc., approved antennas meet the Point-to-Point antenna gain / output
power emissions requirement. The approved antennas with gains greater than 12dBm,
however, can only be used for point-to-point networks and may not be used for pointmultipoint networks. The calculations below illustrate this limitation.
The FCC transmitter power limit for this type of radio is 30 dBm (or 1 watt). In addition,
to ensure safety, the output of this module is limited to 250mW. To meet the FCC
requirements for emissions, the following restrictions on antenna gain must be adhered
to when establishing a radio network.
Point-to-Point network:
max power 250 mW / max antenna gain 24 dBi
? ? The transmitter power reference for a Point-to-Point network is 30dBm (1 watt) of
output power with an antenna gain of 6dBi. For each 1 dB decrease in output
power below this reference point, the antenna gain can increase by 3 dB.
? ? With the OS2400 radio module’s maximum output power of 250 mW, the
maximum allowable antenna gain is 24 dBi in a Point-to-Point application.
(30dBm - 24dBm) + (6dBi * 3) = 24dB
Point-Multipoint network:
max power 250 mW / max antenna gain 12 dBi
? ? The transmitter power reference for a Point-Multipoint network is 30 dBm (1 watt)
of output power with a maximum antenna gain of 6 dBi.
? ? For each 1 dB decrease of output power below this reference point, the antenna
gain can increase by 1 dB.
? ? The OS2400 radio module has a maximum output power of 250 mW or 24 dBm.
Therefore, the maximum allowable antenna gain at full output power is 12 dBi in
a Point-Multipoint application.
(30dBm -24dBm) + 6dBi = 12dBi

The Setup / Diagnostic Software
The OS2400 Setup Application provides a user interface for the configuration and
maintenance of a radio network, regardless of the intended application. It graphically
reflects the physical layout of the component radios.
The Setup Application provides a means to:
? ? configure new networks or radios:
? ? assign roles (Master or Remote) to the radios.
? ? define data paths
? ? set the radio’s operation parameters (baud rate, parity, etc.)
? ? edit existing networks or radios:
? ? add or delete Remote Radios (in point-multipoint networks only)
? ? re-assign roles to the radios.
? ? re-define operation parameters
? ? diagnose functioning of existing networks.
With a MASTER cabled to the PC, the status of each REMOTE can be displayed.
NOTE:
It is recommended that the OS2400 Setup Application be installed on only one computer
and that the network configuration be done from only that one computer.
When a network is designed, the configuration settings are stored in a database which is
internal to the OS2400 Setup Application. When networks are modified, the OS2400
Setup Application depends upon the retrieval of the network’s configuration history.
Network modification and maintenance is easier if the OS2400 Application Software is
installed on only one computer. All subsequent network-related configurations are done
using that one computer.
Through out these Help files, the computer into which the OS2400 Setup Application has
been installed will be referred to as the Configuration PC.

Network Design
Radio Network Basics
RADIO NETWORK DEFINED
A radio network provides wireless replacements for serial cables. Any two devices
which could otherwise function together with a physical serial cable between them can
be incorporated into a wireless network and continue to function as before. The basic
network consists of a Master Radio cabled to one Device and a Remote Radio cabled to
another.
As examples, a Master Device - Remote Device pairs could be:
??
??
??
??
a computer with a printer
a computer with a scanner
a scanner with a printer
a Modbus controller and an industrial tool
A radio link can be used in any situation where a Master Device and its Remote Device
are located such that a serial cable connection between them is impractical or
impossible. The radios are designed to communicate up to 20 miles.
An example of a simple radio network is illustrated below. The Master Device is a
computer and its Remote Device is a hand held terminal.

OS2400 Radio Module
Exhibit 21: User Manual 3
FCC ID: OQ7OS2400
NETWORK_CHANNELS
Network channel selection is used to allow the operation of several networks in the same
location. If the same network channel is selected for two networks which are close to
each other, the networks will interfere with each other, and may not communicate at all.
For network functionality these network channel requirements must be adhered to:
? ? The Master Radio and Remote Radio (or Radios) of each network must be
assigned to the same network channel.
? ? Networks in close proximity must be assigned to different network channels.
The Os2400 radio can support 32 channels. In this case a channel is a 500KHz wide
frequency range used for communication between two radios.
NETWORK TYPES
POINT-TO-POINT
There are two network types, point-to-point and point-to-multipoint.
In all networks there is only one Master Radio.
Point–to–Point networks are the simplest radio network. In a point-to-point network one
Master Radio is cabled to a Master Device and one Remote Radio is cabled to a
Remote Device.
Several point-to-point networks can operate at the same location, however each network
must use a different communication channel.
Each point-to-point network operates independently of each other, there can be no
intercommunication between the point-to-point networks.
15
OS2400 Radio Module
Exhibit 21: User Manual 3
FCC ID: OQ7OS2400
POINT-MULTIPOINT
In Point-Multipoint networks one Master Radio is in communication with at least two
Remote Radios. The Remotes can only communicate with their Master. Remotes
cannot communicate with each other directly, the data must be passed through the
Master. For this reason, a Point-Multipoint network will not work with an application
which requires peer to peer communication.
The OS2400 Point-Multipoint network can only be used with devices that are designed
to use the Modbus communication protocol. In a Modbus network each device has its
own Modbus address. In the network configuration process, each radio’s address must
be correlated with the Modbus address of the device cabled to it.
It may be that the data throughput rate is not as high as in a point-to-point network. In a
point-to-point network the data path is predefined. There are no choices. There is only
one destination. In a point-multipoint network the destination must be determined, the
address information must be resolved before the transmission can proceed.

Installation Planning
SITE SELECTION
A network’s performance can be impacted by attributes of the installation site. An
optimal installation provides for:
??
??
??
??
??
??
??
??
??
??
protection from direct exposure to weather
power source, both adequate and stable
less than 256 radios per channel
radios placed within 20 miles of each other
line of sight between the Master and each Remote antennas, provides the most
reliable communication link
portable Remote radio requirements, maintain a line of sight
proximity of massive structures off of which radio signals can bounce, metal
walls
sources of RF interference, electrical equipment (arc welding, switching power
supplies, etc.)
antennas types
cabling losses, signals lose power over cabled distance
Mounting the antenna on a tower or rooftop can provide a line-of-sight path if the site
contains obstructing terrain or structures. The line-of-sight consideration becomes more
important as the transmission path becomes longer. It is most important as the
transmission path approaches the limiting 20 mile specification.
Though radio frequency communication is reliable, sometimes its performance can be
impacted by intangibles. It is suggested that the network installation planning include
time and resources for performance testing and installation changes.
It is suggested that the installation plan be tested before the network is finally installed.

Physical Installation and Network Verification
Test the Installation Plan
It is suggested that a proposed installation be tested before the installation is finalized.
Once the network has been configured and the radios have been configured:
??
??
??
??
install the Master radio in the 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, then this testing
is at least a two person operation. The system’s diagnostics must be performed
from the Configuration PC.
From the Diagnostic screen of the Configuration PC determine each radio’s Signal
Quality.
To improve the signal quality of each Remote’s communication experiment with:
? ? increasing 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
? ? determine and mitigate sources of “electrical” noise which may be interfering
with the OS2400 transmission
31

Sources of Interference
Radios are designed to detect specific radio frequencies. “Noise”is defined as an
unwanted signal which has been transmitted at the same frequency as the radio was
designed to detect. There are many man-made and natural sources of “noise”.
(lightning, power lines, switching power supplies, fluorescent lighting, microwave ovens,
...)
Due to the spread spectrum and frequency hopping techniques, the OS2400 operates
more efficiently than a radio which operates using conventional technology.
? ? Networks installed in rural areas will encounter less man-made noise than in
suburban or urban areas.
? ? If possible, use a directional (high gain) antenna at the Remote locations.
? ? Verify that each network operating in close proximity to each other has BEEN
ASSIGNED TO A DIFFERENT CHANNEL.
? ? A network’s output power can be changed:
? ? raise the power to “drown out” the competing noise
? ? lower a network’s output power if it is interfering with another network in the vicinity

Modifying an Existing Network
The radios within an existing network can be edited in several ways:
??
??
??
??
??
new radios can be ADDed to a point-multipoint network.
a radio’s settings can be changed (baud rate, output power, channel, etc)
radios can be moved on the Graphical Layout Screen.

A drop down list will appear with the names of the
existing networks.
Note: When a network must be modified or its
function diagnosed, it becomes apparent that
assigning a good descriptive name when the

??
PROPERTIES
??
RADIO
OR
??
quickly double click on the radio’s icon with
the left mouse button
Radio Name: As it appears in this field, the
radio’s name will appear as a label under the
radio’s icon. The name can be any combination of
up to 100 alphanumeric characters and spaces.
Last Configured: The date and time reported
here indicates the last time that the configuration
parameters were modified and saved, or when the
radio was configured, configuration data was
downloaded to the radio.
Serial Port Settings: the serial port settings of the radio radio, (not the PC’s serial port).
Note: The settings of baud rate, parity, data bits (data word size) and stop bits must
match the settings of the device which will be cabled to the radio during normal network
operation.
Radio Address: each radio in the network is automatically assigned a unique address.
If a radio’s address is manually changed to an address already assigned to another
radio in the same network, neither radio will communicate over the network. It is
recommended that this addressing scheme not be changed by the user.
Note: In general, ACCEPT THE DEFAULTS.
The Radio Settings adjust the over the air performance of the radio network:
Transmit Power: This value should be set as low as possible and yet give a reliable
over the air connection to the receiving radio. A higher power setting than necessary
could increase the distance required between two networks operating on the same
channel.
Number of Antennas: This is sometimes referred to as “antenna diversity”. The
use of two antennas allows the radio to cancel out noise. “Noise”is defined as an
unwanted signal which has been transmitted at the same frequency as the radio was
designed to detect. There are many man-made and natural sources of “noise”.
Link Retry Limit: If there is an error in transmission, the transmitting radio will resend the data as many times as set with the Link Retry Limit slider switch. In normal
transmission, the receiving radio “acknowledges” that the data has been received
with no detected errors. If the transmitting radio does not get an acknowledgement,
it will re-transmit until the retry limit has been met. Moving the slider to the right will

Radio’s Address-an explanation
Note: It is suggested that the automatically set radio addresses not be changed. This is
an explanation to soothe the curious.
This Dialog box reflects the settings of a radio which is the Remote of a Point-to-Point
network.
In a Point-to-Point network this dialog box
reports both a Radio address and a
Destination address. The Destination Address
is the address of the radio to which the
selected radio will transmit all data.
By default:
??
Master is assigned to address 1
??
Remote is assigned to address 2
For the Master and Remote the Source and
Destination addresses are the inverse of each
other:
Master
Remote
Address
Destination
If the addresses are to be manually changed,
this inverse relationship must be maintained.
This is the Radio Configuration Dialog box of a radio which is a component of a PointMultipoint network.
In a Point-Multipoint network, all Remote radios
communicate with the Master and the Master
communicates with all Remotes. The pointmultipoint configuration dialog does not have a
Destination Address field.

Glossary
Broadcast Point-Multipoint Network
This is network type where a single master radio sends data to every remote radio in the
network. This is done repeatedly until every remote receives and acknowledges the
data individually. Each remote sends pending data to the master which receives and
acknowledges data sent from each remote. There are multiple remotes for a single
master in this configuration.
Modbus Point-Multpoint Network
This is network with a single Master Radio and multiple Remotes. The devices cabled to
the radios communicate through the Modbus standard protocol. The Master sends data
to a Remote based on the Modbus address of the Modbus device. The data is only sent
to the one Remote device based on its address. Each Remote sends its data only to the
Master. The Master and Remotes acknowledge that the data was received correctly.
Peer to Peer Network
In a Peer-to-Peer network each radio has the ability to receive data from and transmit
data to any other radio in the network.
Point to Point Network
A network consisting of a single master and a single remote radio. All data from the
Master is received and acknowledged by the one Remote. All data from the one
Remote is received and acknowledged by the Master radio.
