  • Page 11: General Description

    RF450 Spread Spectrum Radio General Description The RF450 Spread Spectrum Radio is a 900 MHz license-free radio specifically designed to work with Campbell Scientific dataloggers. RF450 radios consist of a FreeWave DGR09 radio module and an interface board. This manual addresses the RF450’s interface with CR3000, CR1000, and CR800-series dataloggers and a PC running LoggerNet.

  • Page 12: Configuration

    (see FIGURE 4-1). NOTE There may be only one RF450 Master in a network and it must be connected to a PakBus router. A PakBus router may be software such as LoggerNet or PC400 or a datalogger configured as a router.

  • Page 13: Pakbus Graph

    PakBus dataloggers that have been configured in Setup will be shown by the PakBus address in brackets followed by its name assigned through LoggerNet setup. Because RF450 networking protocols are used to direct packets, not PakBus protocols, the network's representation in PakBus Graph may be significantly different than one would expect. FIGURE depicts the physical network of six dataloggers and one LoggerNet server.

  • Page 14: Location Of The Transceivers

    LoggerNet (see FIGURE 4-4). To avoid COM port conflict, DevConfig is usually run when LoggerNet is shut down, and vice versa. The following general procedure is used to configure the RF450 radios via DevConfig: 1. Launch DevConfig by double clicking the icon on the Windows Desktop or through the Windows Start Menu | Start | All Programs | LoggerNet | Device Configuration Utility.

    3. Select the correct COM port for serial communications with the radio. 4. Power the RF450 radio by using the power plug or by using the SC12 cable to connect the radio’s CS I/O port to the datalogger’s CS I/O port.

    Click the Save button to save a configuration file. This file can then be used to load the settings into another RF450. Click the Read File button to load the settings in DevConfig then the Apply button to load the settings into the RF450.

    RF450 Spread Spectrum Radio FIGURE 4-6. DevConfig RF450 Summary Screen Quick Start 1. Using DevConfig, set a unique PakBus Address for each datalogger in the network. Keep the other settings as their default. 2. Decide on a unique Network Identification Number between 0 and 4095, excluding 255.

    RF450 Spread Spectrum Radio 4.6.4 RF450 Operation Mode Setting The Operation Mode option designates the method FreeWave transceivers use to communicate with each other. FreeWave transceivers operate in a Master- to-Slave configuration. Before the transceivers can operate together, they must be set up to properly communicate.

  • Page 20: Network Id

    RF450 Spread Spectrum Radio This box should be checked (set to 1 in Settings Editor) when NOTE running diagnostics from the Master. 4.6.5 Network ID All radios in a multi-point network need to have the same Network ID. The value must be between 0 and 4095 (excluding 255). The ID of 255 is reserved for point-to-point networks.

  • Page 21: Low Power Mode Setting

    EIRP = (Transmitter Power) + (Antenna Gain) - (Cable Losses) [all in dB or dBm] The RF450 maximum power is 30.5 dBm; therefore, a 6 dB (or lower) gain antenna can be used with any Transmit Power setting. If higher gain antennas are used, the cable loss will need to be determined, and the Transmit Power adjusted so as not to exceed the FCC limit of 36 dBm.

  • Page 23: Master Radio

    ID appears in the FreeWave diagnostics program, and allows the user to associate a particular datalogger with its attached radio. To further this association of the RF450 RF network with the PakBus network, the dataloggers (CR1000, CR800, etc.) read the serial number of the attached radio and include this in the datalogger settings when the CS I/O SDC interface is used.

  • Page 24: Slave

    RF450 Spread Spectrum Radio Slave Radios configured as Slaves in a multi-point network are allowed to communicate with a multi-point Master (see FIGURE 4-8). The Slave may communicate with its Master through one or more repeaters. FIGURE 4-8. DevConfig Screen Showing Settings for a Slave in a...

  • Page 25: Power Considerations

    RF450 Spread Spectrum Radio 4.10 Power Considerations The RF450 radio requires 6 to 30 VDC power. This may be supplied through either a wall charger (CSI part number 15966) connected to the DC power jack on the side of the radio or through the datalogger via the CS I/O port.
  • Page 26 9 dBd, with mounts and a Type N female connector. It requires an antenna cable to connect to the radio. Please note that because the FCC limits EIRP to36 dBm, use of this antenna may require a reduction of the RF450’s transmit power. Antenna Cables and Surge Protectors for Outdoor Antennas Recommended for cable lengths less than 10 ft.

  • Page 27: Antenna Cables And Surge Protection

    5.2.2 Electrostatic Issues Many RF450 series installations are out of doors and therefore susceptible to lightning damage, especially via the antenna system. Also, depending on climate and location, electro-statically charged wind can damage sensitive electronics if sufficient electric charge is allowed to accumulate on the antenna and cable.

    2. Add a PakBusPort, set the Maximum Baud Rate to 115200, set the beacon interval to 60 seconds if the Master radio will be at the PC. 3. Add datalogger, set the PakBus address to match that of the datalogger. 4. Apply Settings. FIGURE 6-1. LoggerNet Setup Screen for an RF450 Multi-Point Network...

The only way to exit the setup state is through the proper exit command issued by DevConfig when disconnecting or applying changes. Clear to Send will be solid red with a solid link, as the link weakens the CTS on the Repeater and Slave will begin to flash.
  • Page 31 LEDs flash when LoggerNet command transmitted but no response from datalogger: 1. Check SC12 cable on the datalogger's CS I/O port. 2. Check SDC address in RF450. 3. Check SDC address in datalogger. 4. Check the baud rate of LoggerNet; it should match the baud rate of the RF450 attached to it.
