Chapter 3: Integration Keep the following integration points in mind, when embedding a FreeWave radio into your OEM equipment: l 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 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.
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.
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: 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.
MM2 Wireless Data Transceivers 1. Plug a serial cable into the COM 1 port on the transceiver, connect the cable to a COM port on the computer running Tool Suite, and connect the transceiver to a power source. 2. Open Tool Suite and select Setup Terminal in the Applications pane. 3. From the drop-down list at the top left of the window, select the COM port on the computer to which the transceiver is connected. 4. Click Connect. 5. Place the transceiver in Setup Mode. l Short Pin 2 to ground.
Chapter 4: Networks and Programming Using Tool Suite to Connect to and Program Transceivers 1. Connect a serial or diagnostic cable between the computer or laptop and the radio. 2. Connect the power supply to the transceiver and the power source and turn on the radio. 3. With the radio connected to the computer in Tool Suite, click Configuration in the Application pane to display the Configuration application. 4. Ensure the correct port is selected in the Com Port field in the Configuration ribbon. 5.
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.

Chapter 5: Troubleshooting The main areas to address when initially troubleshooting a radio network are as follows: l LEDs on the radio l Radio Settings l 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.
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 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.
