    Spread Spectrum Wireless Data Transceiver User Manual Quick Start on a Point-to-Point Network When purchased as a pair, the FreeWave® Wireless Data Transceivers are shipped from the factory pre- configured with most of the settings to operate in Point-to-Point applications. To establish communications between a pair of FreeWave Wireless Data Transceivers just received from the factory: Connect the transceiver to the instrument with the RS232 cable and also attach power.

  • Page 11: Choosing A Location For The Transceivers

    Placement of the FreeWave transceiver is likely to have a significant impact on its 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 will have a better communication link. In practice, the transceiver should be placed away from computers, telephones, answering machines and other similar equipment.

  • Page 30: Radio Transmission Characteristics

    This is to minimize the interference with other FreeWave transceivers operating in the area. For instance, if 10 pairs of FreeWave transceivers are operating on different networks in close proximity, setting a different FreqKey value reduces the chance that transceivers will hop to the same frequency at the same time.

  • Page 31: Hop Table Version

    (2) H FFSET The Hop Freq Offset option is not functional in the 900 MHz spread spectrum transceiver. Note: Regardless of the FreqKey used, all transceivers in either Point-to-Point or Point-to-MultiPoint networks must be set to identical Hop Table Version, Hop Table Size and Hop Freq Offset.

  • Page 32: Frequency Zone

    Spread Spectrum Wireless Data Transceiver User Manual (3) F REQUENCY Frequency Zone: The idea of frequency zoning is to divide the available band (902MHz to 928 MHz) into 16 smaller bands each consisting of 5, 7, or 8 Frequency channels depending on the frequency zone. These 16 zones are controlled by selecting option 3 and then entering a 1 (Enable) or a 0 (Disable) next to the appropriate zone number.
  • Page 33 Spread Spectrum Wireless Data Transceiver User Manual FCC regulations require a minimum of 50 separate frequency channels be used within a WARNING: hop pattern. Using the Standard hop table, a minimum of 7 frequency zones are required for legal communication. Please reference the above table for number of channels per zone to adhere to this requirement.

  • Page 34: Freqkey In 2.4 Ghz Transceivers

    Spread Spectrum Wireless Data Transceiver User Manual 2.4 GH EY IN RANSCEIVERS The Frequency Key for the 2.4GHz transceivers works very similarly to that of the 900MHz transceivers. The selection of 15 FreqKeys (0-9 and A-E) is identical to the 900MHZ, allowing for 15 different pseudo- random patterns.

  • Page 35: Frequency Zone

    Spread Spectrum Wireless Data Transceiver User Manual (3) F REQUENCY Frequency Zone allows the user to select which portions of the band the network will use. Setting a zone to 1 will include it in the hopping pattern, while setting the zone to 0 will exclude that zone. Below is the frequency zone table displaying the beginning frequency and ending frequency in each of the 16 zones.

  • Page 36: Max Packet Size And (2) Min Packet Size

    Spread Spectrum Wireless Data Transceiver User Manual FCC regulations require a minimum of 50 separate frequency channels be used within a WARNING: hop pattern. Using the Standard hop table, a minimum of 5 frequency zones are required for legal communication.

  • Page 37: Xmit Rate

    (4) RF D FreeWave transceivers have two settings for the RF Data Rate (2, 3). RF Data Rate should not be confused with the serial port Baud Rate. Setting 2 should be used when the transceivers are close together and data throughput needs to be optimized. Setting 2 must also be used when the full throughput of 115.2KBaud is necessary.

  • Page 38: Slave Security

    Slave may need to accept calls from more than 10 different Masters. When Slave Security is set to 1, the transceiver will accept calls from any other FreeWave transceiver. Additional network security measures may be taken to prevent unauthorized access, such as changing default settings for FreqKey, Hop Table or Frequency Zones.

  • Page 39: Retry Time Out

    Note: Setting Retry Time Out to 20 is recommended in areas where several FreeWave networks exist. This setting will allow Slaves and Repeaters to drop the connection if the link becomes too weak, while at the same time prevent errant disconnects due to interference from neighboring networks.

  • Page 40: (A) High Noise

    When a noise problem is shown to be helped by way of the High Noise option, chances are that the noise may be further squelched by use of a band pass filter available for sale from FreeWave Technologies. (B) MCU SPEED MCU Speed controls the speed of the Micro Controller Unit in the transceiver.

  • Page 41: Show Radio Statistics

    Spread Spectrum Wireless Data Transceiver User Manual NOTE: This feature may be used to save power in Repeaters. By turning off the on board LED’s (setting = 2) the current consumption is reduced. To reduce current consumption in Slaves, use the setting “Low Power = 1”.

  • Page 42: Average Noise Level

    The Radio Temperature value is the current operating temperature of the transceiver in degrees Celsius. For proper operation, a FreeWave transceiver must be in the temperature range of -40° to +75° C. Some of the transceivers are only tested to 0° C. See transceiver specification papers for details.

  • Page 43: Number Repeaters

    Spread Spectrum Wireless Data Transceiver User Manual (0) N UMBER EPEATERS In a MultiPoint network it is critical to transmission timing to configure this parameter correctly. The value should be 0 if no Repeaters are in the network and 1 if any number of Repeaters are present. This parameter should be set to the same value in all transceivers in a MultiPoint network.

  • Page 44: Max Slave Retry

    Spread Spectrum Wireless Data Transceiver User Manual Slaves communicating through this Repeater will only receive the initial packet from the Master with no repeats. Therefore, if the packet is not received on the first try, the Slave will not respond as expected.

The example below shows the most common and straightforward link; a Master communicating to a Slave in a Point-to-Point link.
  • Page 53 Spread Spectrum Wireless Data Transceiver User Manual The example below shows a configuration where a Master routinely calls a number of Slaves at different times. The Master is communicating with a transceiver designated as a Slave/Repeater that is connected to a remote device. Since this device is placed in an elevated location, the transceiver may also be used as a Repeater when it is not used as a Slave.
  • Page 54 Spread Spectrum Wireless Data Transceiver User Manual The last example is a Point-to-MultiPoint network which uses one of the sites as a Slave/Repeater. This network functions in the same manner as a standard MultiPoint network with Repeaters. However, the number of radios may be reduced with the use of the MultiPoint Slave/Repeater feature.
