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: Antenna radiation patterns / antenna type Power gain Cable loss Directionality Polarization 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 Radio Statistics, 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: Identify sites with “Line of Sight”. If you cannot see it you cannot talk to it. Long cable runs decrease signal and increase the amount of picked up noise. For example, if you use LMR 400 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. Antenna gain does not exceed 12 dBi for Yagi antennas and 8.15 dBi for Omni antennas. Overall 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 Antennas Antenna FreeWave Part Number Manufacturer Gain (dBd/dBi) Manufacturer Type for Ordering Model Number 12 dBi Wavelink Yagi EAN0906F PRO890-12 6 dBd / 8.15 dBi Antenex Omni EAN0906NF FG9026 3 dBd/ 5.15 dBi Maxrad Omni EAN0900WC MAX-9053 2.85 dBd / 5.0 dBi Antenex Omni EAN0905WC EB8965C Maxrad BMEFC8985HD -0.15 dBd / 2.0 dBi Mobile Mark Omni EAN0900SR PSKN3-925S -2.15 dBd/ 0 dBi Mobile Mark Omni EAN0900SQ PSTG0-915SE 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. LIM0001AA Rev E Chapter 2: Hardware and Pinouts 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. Cable Type Attenuation (db/100 ft) Run Length (ft) Total Run Attenuation (dB) LMR400 3.93 25 1.0 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.

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 the items listed below.This information can help you troubleshoot your network, and also help you as you expand your network. All radio settings. Radio serial numbers. Model numbers. Tower heights. Exact geographic locations. Any other parameters that can affect radio communication. LIM0001AA Rev E 21 Chapter 4: Networks and Programming 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: Tool 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. Terminal 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 Parity None Stop Bits 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.

To send only the parameters you have changed , within the Configuration application, in the Network Title ribbon, click Quick. To send all the settings for all parameters, within the Configuration application, in the Network Title ribbon, click All. To 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. LIM0001AA Rev E 24 MM2 Wireless Data Transceivers 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: A setting of this parameter on the Master between 1 and 128. A second computer or serial connection to run the diagnostics software. A diagnostics cable (available from FreeWave). Diagnostics software (available on the User Manual and System Tools CD and on www.FreeWave.com). LIM0001AA Rev E 25 LIM0001AA Rev E 26 Chapter 5: Troubleshooting The main areas to address when initially troubleshooting a radio network are as follows: LEDs on the radio Radio Settings RF 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 Solid green Off Solid red bright Solid red bright Solid red dim Solid red bright MultiPoint Slave (linked) Point-to-Point Master (unlinked) 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. LIM0001AA Rev E 27 Chapter 5: Troubleshooting 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. LIM0001AA Rev E 28 MM2 Wireless Data Transceivers 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.
