To improve the data link, FreeWave offers various antennas withcable 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 typelPower gainlCable losslDirectionalitylPolarizationWhen using antennas, follow the guidelines for selection, location, and installation provided in the sectionsbelow.Antenna LocationWhen using an external antenna, placement of the FreeWave transceiver's antenna is likely to have asignificant impact on the transceiver's performance. The key to the overall robustness of the radio link is theheight of the antenna. In general, FreeWave units with a higher antenna placement have a bettercommunication link. However, a higher antenna may pick up more RF noise in the area, and other antennas inclose proximity could cause interference. An adjustment as little as 2 feet in antenna placement can resolvesome noise problems. In extreme cases, such as when interference is due to a pager or cellular tower, theband pass filters that FreeWave offers, may reduce this out-of-band noise.Note: Use the RadioStatistics, available in option 4 in the main Setup menu of theradio 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 youuse LMR400 cable on a 200 foot tower, loss in the cable run alone is 8 dB over the 200 footdistance.To help optimize your antenna location, have FreeWave complete a site study for you, free of charge.

MM2 Wireless Data TransceiversLIM0001AA Rev B (DRAFT)Approved Antennas for the 900 MHz MM2 Radio FamilyAny antenna used with FreeWave transceivers must have the following characteristics to remain incompliance with FCC requirements and regulations.lAntenna gain does not exceed 8.15 for Omni antennas.lOverall system Equivalent IsotropicallyRadiated Power (EIRP) does not exceed 36dBm.The complete list of antennas available fromFreeWave including antenna gains is shown below:900 MHz Omni-Directional AntennasGain (dBd/dBi) ManufacturerFreeWave PartNumber for OrderingManufacturerModel Number6 dBd / 8.15 dBi Antenex EAN0906NF FG90263 dBd/ 5.15 dBi Maxrad EAN0900WC MAX-90532.85 dBd / 5.0 dBi AntenexMaxradEAN0905WC EB8965CBMEFC8985HD-0.15 dBd / 2.0 dBi Mobile Mark EAN0900SR PSKN3-925S-2.15 dBd/ 0 dBi Mobile Mark EAN0900SQ PSTG0-915SEAntenna InstallationAntennas must be professionally installed on a fixed, mounted, and permanent structure to satisfy RFexposure requirements.Warning! Any antenna placed outdoors must be properly grounded. Use extremecaution when installing antennas and follow all manufacturer instructions included withthe antenna.Per FCC regulations, any antenna used with FreeWave transceivers must be an approved antenna that hascomparable performance parameters. For more information about approved antennas, see "ApprovedAntennas for the 900 MHz MM2 Radio Family" on page 7.Cable Loss and Transmit Power SettingsThe Transmit Power parameter is the output power of the transceiver. The transceiver output power levelmust be set to satisfy maximum Equivalent IsotropicallyRadiated Power (EIRP) requirements in the countryin which the installation exists.When setting up the network, consider the power gain that an antenna may add, and the power loss throughcabling. Adjust the Transmit Power on the transceiver to ensure that you do not exceed the maximum EIRPfor the regulating body where the installation exists. Use the tables below to determine the correct TransmitPower parameter setting for each transceiver in the network.Important: The information in this section discusses FCC and ETSI maximum EIRPregulations. Ensure your installation meets the maximum EIRP requirements for thecountry in which you are installing transceivers. It remains the installer's responsibilityto ensure that an installation is within EIRP emission limits.7Draft
Chapter 2: Hardware and PinoutsLIM0001AA Rev B (DRAFT)The FCC permits 1 Watt output power at the transceiver and 36 dBm (4 Watts) at the antenna. Whencalculating the power gain, use the following equation to determine the total output power at the antenna.Losscalculations should include cable, connectors, surge protectors, and so on.Transceiver Output – Losses + Antenna Gain = Output Antenna PowerFor example, 30 dBm – 2 dB + 6 dB = 34 dBm (or 2.5 Watts). 34 dBm is within the FCC limits. However,30dBm – 2dB + 10dB = 38 dBm (or 6.3 Watts) exceeds the FCC limits.CableTypeAttenuation(db/100 ft) Run Length (ft) Total Run Attenuation (dB)LMR400 3.93 25 1.0LMR500 3.154 25 0.8LMR600 2.518 25 0.6LMR900 1.709 25 0.4ShieldingFreeWave OEM transceivers are shielded to prevent any unintended emission. Additional shielding may berequired to prevent the OEM equipment from interfering with the FreeWave transceiver. This is unlikely but itdepends on the equipment and components in the OEM application.8Draft

Click Read Radio in the Configuration ribbon to read the transceiver's current settings.7. Make the necessary parameter changes and do one of the following to send the changes to thetransceiver.lTo send only the parameters you have changed , within the Configuration application, in theNetwork Title ribbon, click Quick.lTo send all the settings for all parameters, within the Configuration application, in the NetworkTitle ribbon, click All.lTo set a device back to its factory default settings, within the Configuration application, in theNetwork Title ribbon, click Default.For more information about using Tool Suite, see the Tool Suite User Manual available on the User Manualand System Tools CD or by selecting File > Help in the Tool Suite software.Settings to NoteEach of the parameters available to set on each model is described in detail in the user manual for that modelHowever, when setting up your network and defining parameters, especially note the following parametersettings for your OEM setup.Low Power ModeNote: This setting applies only to Multipoint Slave transceivers using the RS232protocol. Low Power Mode does not work with MultiPoint Repeaters becausethey are constantly transmitting. RS232 protocol is available in the MM2-MR-Rmodels.FreeWave transceivers can be programmed to a low power state for battery/solar operation. There are severalsettings to the Low Power Mode, the higher the setting the lower the power. The transceiver can operate aslow as 6 mA in the lowest power mode compared to 25 mA in idle mode. The transceiver also dims its LEDs tosave power in this mode.A Slave in a Multipoint network set to use Low Power Mode takes slightly longer to communicate with theMaster.For more information about Low Power Mode, see the user guide for the transceiver you are integrating.DiagnosticsThe 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. Forexample, if you set to 10, 1 out of every 10 data slots is for diagnostics data; if you set to 100, 1 out of every100 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.24Draft
MM2 Wireless Data TransceiversLIM0001AA Rev B (DRAFT)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 onwww.FreeWave.com).25Draft

LIM0001AA Rev B (DRAFT)Chapter 5: TroubleshootingThe main areas to address when initially troubleshooting a radio network are as follows:lLEDs on the radiolRadio SettingslRF QualityIf you are experiencing trouble with a radio in you network, use the troubleshooting information available in thischapter to help determine the issue. If you continue to have issues, contact FreeWave Technical Support.TroubleshootingMy 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 theirprevious state.Additional symptoms of this problem include:CarrierDetect(CD)Transmit(Tx)Clear toSend(CTS)MultiPoint Master Solid red bright Solid red dim OffMultiPoint Slave (unlinked) Solid red bright Off Blinking redMultiPoint Slave (linked) Solid green Off Solid red brightPoint-to-Point Master (unlinked) Solid red bright Solid red dim Solid red brightPoint-to-Point Master or Slave Solid green Intermittent flash red Intermittent flash redTwo scenarios could be causing the radio to not enter Setup mode.27Draft
Chapter 5: TroubleshootingLIM0001AA Rev B (DRAFT)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 (orone 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 intothe 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 havereplaced 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 hada FreeWave network out here in the same area for a long time and they are not having issues. Whatis 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 settingsfrom the default settings.Most of my sites report in and I can poll, but I cannot poll any of the Slaves that talk back toRepeater 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 ofSlaves that I cannot poll.A Parallel Repeater has been added/changed in the network and has the same frequency settings and is nowinterfering 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 pollagain 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 theMaster and it keeps trying to resend data to the Master locking out all other communications to the Master.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.28Draft
MM2 Wireless Data TransceiversLIM0001AA Rev B (DRAFT)I installed a new Slave in my network, but I cannot get it to link. The CD light is solid red and theCTS 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 theantenna, cabling, connections, etc. Verify that the cabling, connectors, and the antenna are connectedcorrectly and have not sustained any damage.When I connect directly to my RTU I am able to poll data successfully. When I add in thetransceivers, I cannot get any data from my poll.Baud rate above 38,400 may need flow control line connected.29Draft
