MM2 Wireless Data Transceivers 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. l Antenna gain does not exceed 8.15 for Omni antennas. l Overall system Equivalent Isotropically Radiated Power (EIRP) does not exceed 36 dBm.
Chapter 2: Hardware and Pinouts 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, and so on. Transceiver Output – Losses + Antenna Gain = Output Antenna Power For example, 30 dBm – 2 dB + 6 dB = 34 dBm (or 2.5 Watts). 34 dBm is within the FCC limits.

ft Chapter 3: Integration Keep the following integration points in mind, when embedding a FreeWave radio into your OEM equipment: RS232 signals range from -15.0 to +15.0 and TTL signals range from 0 to +5 V. l FreeWave radios are shielded to prevent any unintended emission. Depending on the OEM equipment design, additional shielding may be required to prevent the OEM equipment from interfacing with the FreeWave device.

Input Low Level Voltage (VIL) 0.0 to 0.8 VDC The positive voltage applied to the input which will be accepted by the device as a logic low. Input High Level Voltage (VIH) 2.0 to 5.0 VDC The positive voltage applied to the input which will be accepted by the device as a logic high.
ft Chapter 4: Networks and Programming ra 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 D 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.
Chapter 4: Networks and Programming l 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.
MM2 Wireless Data Transceivers 4. Click Connect. 5. Place the transceiver in Setup Mode. l Short Pin 2 to ground. For pin location, see "Embedded Radio Connector Pinouts" on page 3. l If using a data cable (FreeWave part number: ASC3610DB or ASC3610DJ), press the Setup button on the data cable.
Chapter 4: Networks and Programming If using a Data Cable (FreeWave part number: ASC3610DB or ASC3610DJ), press the Setup button on the data cable. If using a Data Cable (P/N ASC3610DB or ASC3610DJ), press the Setup button. If using the gray ribbon Diagnostic Cable (P/N AC2009DC), or the black Diagnostic Cable (P/N ASC0409DC), press Shift-U (capital U) to invoke the Setup menu. All three LEDs on the transceiver light green and stay green as long as the transceiver is in Setup mode. 6.
MM2 Wireless Data Transceivers Diagnostics requires the following: A setting of this parameter on the Master between 1 and 128. l A second computer or serial connection to run the diagnostics software. l A diagnostics cable (available from FreeWave). l Diagnostics software (available on the User Manual and System Tools CD and on www.FreeWave.com).

ft Chapter 5: Troubleshooting The main areas to address when initially troubleshooting a radio network are as follows: LEDs on the radio l Radio Settings l RF Quality ra l 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.
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.
MM2 Wireless Data Transceivers 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.
