About Antennas
FreeWave offers many antenna options. To improve the data link, FreeWave offers various antennas with
cable lengths ranging from 13 inches up to 200 feet.
Consider the following antenna characteristics when choosing an antenna for your application:
lAntenna radiation patterns / antenna type
lPower gain
lCable loss
lDirectionality
lPolarization
When using antennas, follow the guidelines for selection, location, and installation provided in the sections
below.
Antenna Location
When using an external antenna, placement of the FreeWave transceiver's antenna is likely to have a
significant impact on the transceiver's performance. The key to the overall robustness of the radio link is the
height of the antenna. In general, FreeWave units with a higher antenna placement have a better
communication link. However, a higher antenna may pick up more RF noise in the area, and other antennas in
close proximity could cause interference. An adjustment as little as 2 feet in antenna placement can resolve
some noise problems. In extreme cases, such as when interference is due to a pager or cellular tower, the
band pass filters that FreeWave offers, may reduce this out-of-band noise.
Note: Use the RadioStatistics, available in option 4 in the main Setup menu of the
radio to help identify problems.
Also consider the following points when locating antennas for your application:
lIdentify sites with “Line of Sight”. If you cannot see it you cannot talk to it.
lLong cable runs decrease signal and increase the amount of picked up noise. For example, if you
use LMR400 cable on a 200 foot tower, loss in the cable run alone is 8 dB over the 200 foot
distance.

Approved Antennas for the 900 MHz MM2 Radio Family
Any antenna used with FreeWave transceivers must have the following characteristics to remain in
compliance with FCC requirements and regulations.
lAntenna gain does not exceed 12 dBi for Yagi antennas and 8.15 dBi for Omni antennas.
lOverall system Equivalent Isotropically Radiated Power (EIRP) does not exceed 36dBm.

Antenna Installation
Antennas must be professionally installed on a fixed, mounted, and permanent structure to satisfy RF
exposure requirements.
Warning! Any antenna placed outdoors must be properly grounded. Use extreme
caution when installing antennas and follow all manufacturer instructions included with
the antenna.
Mise en garde ! Toute antenne placée à l'extérieur doit être correctement mise à la
terre. Soyez très prudent lors de l'installation d'antennes et suivre toutes les
instructions du fabricant fournies avec l'antenne.
Per FCC regulations, any antenna used with FreeWave transceivers must be an approved antenna that has
comparable performance parameters. For more information about approved antennas, see "Approved
Antennas for the 900 MHz MM2 Radio Family" on page 7.

Chapter 2: Hardware and Pinouts
LIM0001AA Rev E
Cable Loss and Transmit Power Settings
The Transmit Power parameter is the output power of the transceiver. The transceiver output power level
must be set to satisfy maximum Equivalent Isotropically Radiated Power (EIRP) requirements in the country
in which the installation exists.
When setting up the network, consider the power gain that an antenna may add, and the power loss through
cabling. Adjust the Transmit Power on the transceiver to ensure that you do not exceed the maximum EIRP
for the regulating body where the installation exists. Use the tables below to determine the correct Transmit
Power parameter setting for each transceiver in the network.
Important: The information in this section discusses FCC and ETSI maximum EIRP
regulations. Ensure your installation meets the maximum EIRP requirements for the
country in which you are installing transceivers. It remains the installer's responsibility
to ensure that an installation is within EIRP emission limits.
The FCC permits 1 Watt output power at the transceiver and 36 dBm (4 Watts) at the antenna. When
calculating the power gain, use the following equation to determine the total output power at the antenna. Loss
calculations should include cable, connectors, surge protectors, etc.
Transceiver Output – Losses + Antenna Gain = Output Antenna Power
For example, 30 dBm – 2 dB + 6 dBi = 34 dBm (or 2.5 Watts). 34 dBm is within the FCC limits. However, 30
dBm – 2 dB + 10 dBi = 38 dBm (or 6.3 Watts) exceeds the FCC limits.

LMR500 3.154 25 0.8
LMR600 2.518 25 0.6
LMR900 1.709 25 0.4
Shielding
FreeWave OEM transceivers are shielded to prevent any unintended emission. Additional shielding may be
required to prevent the OEM equipment from interfering with the FreeWave transceiver. This is unlikely but it
depends on the equipment and components in the OEM application.

Chapter 3: Integration
Keep the following integration points in mind, when embedding a FreeWave radio into your OEM equipment:
lRS232 signals range from -15.0 to +15.0 and TTL signals range from 0 to +5 V.
lFreeWave radios are shielded to prevent any unintended emission. Depending on the
OEMequipment design, additional shielding may be required to prevent the OEM equipment from
interfacing with the FreeWave device.
lTo connect the radio to the OEM device without modifying the OEM circuit board, see the cable
options and connector pinouts in this guide. The OEM equipment needs to support TTL singals for
the MM2-T.
In addition, this chapter provides information about the following elements to consider:
lCurrent Measurements
lTTL Signals and Timing
lPCBBoard Design Guidelines
Current Measurements
The embedded radios discussed in this manual have the following current measurements.

Chapter 4: Networks and Programming
This chapter provides information about setting up your network and how to program the transceiver
configuration settings. For detailed information about each setting, see the user guide for the transceiver you
are integrating.
Setting Up the Network
When designing and setting up a Point-to-Multipoint network, FreeWave recommends using Network IDs and
Subnet IDs to route communications back to the Master. Only use the Call Book for small networks that
contain under 10 Slaves, as it is limited to 10 Slaves with or without Repeaters in Point-to-Point networks.
Repeaters are limited to 2 per Slave for 10 Slaves maximum, or 4 per Slave for 5 Slaves maximum. For more
information about setting up networks, see the user guide for the transceiver you are integrating.
As you design and deploy your network, document your design including all theitems listed below.This
information can help you troubleshoot your network, and also help you as you expand your network.
lAll radio settings.
lRadio serial numbers.
lModel numbers.
lTower heights.
lExact geographic locations.
lAny other parameters that can affect radio communication.

Chapter 4: Networks and Programming
LIM0001AA Rev E
Programming Methods
Each FreeWave radio has a series of commands and settings that you can define that determine how the
radio functions. You can access these commands in the following ways:
lTool Suite - Most, but not all OEM radios are available for configuration using the FreeWave Tool
Suite application. Tool Suite provides a group of tools for configuring the devices in your network
and for monitoring your network's performance. Using the Configuration application within Tool
Suite, you can program changes to your transceiver's settings.
Tool Suite is available on the User Manual and System Tools CD and is available for download
from www.FreeWave.com. For more information about using Tool Suite, see the Tool Suite
User Manual available on the User Manual and System Tools CD or by selecting File > Help
in the Tool Suite software.
lTerminal Emulator - A terminal emulator program, such as HyperTerminal or Tera Term, offers
many of the same configuration options that are available in the Configuration application in Tool
Suite. Terminal emulators vary in cost, and several are downloadable free of charge. If you run
versions of the Windows operating system prior to Windows 7, HyperTerminal is included in the
operating system installation. However, if you are running Windows 7 or newer, HyperTerminal is
no longer available.
You can use the terminal emulator program of your choice to program the transceiver.
The Setup Terminal application within Tool Suite provides the same interface that is
available using a terminal emulator.
Accessing the Setup Menu Using a Terminal Emulator
Use a terminal emulator of your choice to access the Setup menu. For any terminal emulator application, plug
the serial cable into a COM port on the transceiver, open a session, and ensure that the port settings are set to
the following for a proper connection to the transceiver:
Port Setting Select
Bits per second 19200
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
The following instructions describe how to access the transceiver's Setup menu using the Setup Terminal
application within Tool Suite. Setup Terminal contains the port settings above, by default. For more
information about using Tool Suite, see the Tool Suite User Manual available on the User Manual and System
Tools CD or by selecting File > Help in the Tool Suite software

button on the data cable.
If you are using the gray ribbon diagnostic cable (part number: AC2009DC), or the black
diagnostic cable (part number: ASC0409DC), the transceiver changes to Setup mode
automatically when you click Read Radio in Tool Suite.
All three LEDs on the transceiver light green and stay green as long as the transceiver is
in Setup mode.
As you navigate through the Setup menu and make changes to the parameters, the parameters are
sent to the transceiver immediately.

lTo send all the settings for all parameters, within the Configuration application, in the Network
Title ribbon, click All.
lTo set a device back to its factory default settings, within the Configuration application, in the
Network Title ribbon, click Default.
For more information about using Tool Suite, see the Tool Suite User Manual available on the User Manual
and System Tools CD or by selecting File > Help in the Tool Suite software.
Settings to Note
Each of the parameters available to set on each model is described in detail in the user manual for that model
However, when setting up your network and defining parameters, especially note the following parameter
settings for your OEM setup.
Low Power Mode
Note: This setting applies only to Multipoint Slave transceivers using the RS232
protocol. Low Power Mode does not work with MultiPoint Repeaters because
they are constantly transmitting. RS232 protocol is available in the MM2-MR-R
models.
24

MM2 Wireless Data Transceivers
LIM0001AA Rev E
FreeWave transceivers can be programmed to a low power state for battery/solar operation. There are several
settings to the Low Power Mode, the higher the setting the lower the power. The transceiver can operate as
low as 6 mA in the lowest power mode compared to 25 mA in idle mode. The transceiver also dims its LEDs to
save power in this mode.
A Slave in a Multipoint network set to use Low Power Mode takes slightly longer to communicate with the
Master.
For more information about Low Power Mode, see the user guide for the transceiver you are integrating.
Diagnostics
The Diagnostics setting allows diagnostics data to be viewed at the Master in parallel with application data.
The setting in this parameter determines how many slots out of 128 are dedicated to diagnostics. For
example, if you set to 10, 1 out of every 10 data slots is for diagnostics data; if you set to 100, 1 out of every
100 data slots is for diagnostics data.The diagnostic program must be run from the Master transceiver.
Note: Diagnostics is always secondary to actual transmitted data.
Diagnostics requires the following:
lA setting of this parameter on the Master between 1 and 128.
lA second computer or serial connection to run the diagnostics software.
lA diagnostics cable (available from FreeWave).
lDiagnostics software (available on the User Manual and System Tools CD and on
www.FreeWave.com).

Chapter 5: Troubleshooting
The main areas to address when initially troubleshooting a radio network are as follows:
lLEDs on the radio
lRadio Settings
lRF Quality
If you are experiencing trouble with a radio in you network, use the troubleshooting information available in this
chapter to help determine the issue. If you continue to have issues, contact FreeWave Technical Support.
Troubleshooting
My radio does not stay in Setup mode and I am not able to program it through the diagnostics port.
when I try to place the radio into Setup mode, all three LEDs flash green, and then go back to their
previous state.
Additional symptoms of this problem include:
Carrier
Detect
(CD)
Transmit
(Tx)
Clear to
Send
(CTS)
MultiPoint Master Solid red bright Solid red dim Off
MultiPoint Slave (unlinked) Solid red bright Off Blinking red
MultiPoint Slave (linked) Solid green Off Solid red bright
Point-to-Point Master (unlinked) Solid red bright Solid red dim Solid red bright
Point-to-Point Master or Slave Solid green Intermittent flash red Intermittent flash red
Two scenarios could be causing the radio to not enter Setup mode.

The radio is wired for RS485 and Pins 5 and 7 on a board level radio, or Pins 2 and 3 on an enclosed radio (or
one with a DB9 connector) are shorted together.
1. Separate the wires and place the radio into Setup.
2. Change the Setup Port parameter in the Baud Rate tab to Diagnostic Only.
If there is a data source (PLC, RTU, PC, or Terminal Server) connected to the data port data is coming into
the data port while you are trying to access Setup through the diagnostics port.
1. Disconnect the data source and place the radio into Setup.
2. Change Setup Port parameter in the Baud Rate tab to Diagnostic Only.
My transceivers are linked, but I cannot pass data.
Verify that the Baud Rate and Data Parity settings match between devices.
We recently had a bad storm with lots of lightning and my transceiver has not worked since. I have
replaced the transceiver but it still does not link.
Verify that the coax cable or antenna were not damaged in the storm.
I have a new network. My radios are linked but I am not able to pass data. Gas Company X has had
a FreeWave network out here in the same area for a long time and they are not having issues. What
is wrong?
Your network is likely using the default settings for Frequency Key,Network IDs,Minimum Packet Size,
and Maximum Packet Size. Refer to the user manual for the transceiver you added and change your settings
from the default settings.
Most of my sites report in and I can poll, but I cannot poll any of the Slaves that talk back to
Repeater 2.
Repeater 2 is experiencing high noise.
My network has been running flawlessly for the last 2 years. Now, all of a sudden, I have a group of
Slaves that I cannot poll.
A Parallel Repeater has been added/changed in the network and has the same frequency settings and is now
interfering with the other Repeater. Program the new Repeater with a different set of parameters.
My network keeps locking up. If I cycle power on the Master, the network is restored and I can poll
again until the next time the network locks up.
There is a "chatty" Slave in the network. The Slave is not getting acknowledgement of data it sends to the
Master and it keeps trying to resend data to the Master locking out all other communications to the Master.

MM2 Wireless Data Transceivers
LIM0001AA Rev E
This is typically caused by a bad signal from the Slave to the Master. Verify line of sight, antenna direction,
and noise levels at the Slave.
I installed a new Slave in my network, but I cannot get it to link. The CD light is solid red and the
CTS light is blinking red.
LOS (Line of Sight) issue or settings issue.
I have a site that used to perform flawlessly. Now I cannot reliably get data from the RTU at this site.
Antenna reflected power causing problem. Reflected power may be caused by defects or damage in the
antenna, cabling, connections, etc. Verify that the cabling, connectors, and the antenna are connected
correctly and have not sustained any damage.
When I connect directly to my RTU I am able to poll data successfully. When I add in the
transceivers, I cannot get any data from my poll.
Baud rate above 38,400 may need flow control line connected.
