    FreeWave will potentially operate in virtually any environment where RS232 data communications occur. The transceivers function as a 9 pin null modem cable. If FreeWave is to be used in an application where a null modem cable is used (such as communication between two computers), then FreeWave can be connected directly.

  • Page 17: Tuning Transceiver Performance

    900 MHz and 2.4 GHz V5.0S Tuning Transceiver Performance FreeWave allows you to tune several parameters to optimize its performance for your particular application. All adjustments are done through the FreeWave setup program, a user interface which eliminates the need for setup diskettes, DIP switch settings, or custom software.

  • Page 18: Figure 1: Initial Menu

    900 MHz and 2.4 GHz V5.0S When the setup program is invoked all three LEDs on the FreeWave front panel will turn green and will remain green for the entire time the Transceiver is in setup mode. The main menu screen for the setup program is shown in Figure 1:...

    LEDs will be solid red. (1) Point-to-Point Slave When set up as a point to point slave a FreeWave Transceiver will communicate with any master in its call book, either directly or through up to four repeaters. When functioning as a slave, the Entry to Call feature in the Transceiver's call book (Figure 7) is not operational.

  • Page 21: Point-To-Point Repeater

    900 MHz and 2.4 GHz V5.0S (5) Point-to-Point Repeater FreeWave allows the use of up to four repeaters in a point to point communications link, significantly extending the operating range. When designated as a repeater a Transceiver behaves as a pass-through link.

    Please contact FreeWave Technologies if you have any questions about the installation of multipoint systems.

  • Page 26: Overlapping Multipoint Systems

    900 MHz and 2.4 GHz V5.0S Overlapping Multipoint Systems Overlapping multipoint systems may be set up with FreeWave transceivers effectively if a couple of key parameters are set correctly. Overlapping multipoint systems are defined as systems using different masters which share or overlap in a specific geographic area. It may include colocation of units (generally repeaters) which are part of different systems.
  • Page 27 FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S It is important to keep in mind that increasing the master packet repeat will not only increase the probability of a packet getting through, but will also increase latency in the system because each packet from the master or repeater is being sent more often.

  • Page 28: Master Packet Repeat In Multipoint Systems With Repeaters

    FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Master Packet Repeat in Multipoint Systems with Repeaters The Master Packet Repeat parameter must also be set in multipoint repeaters when they are used in a multipoint system. In a multipoint system a repeater looks like a master to a slave.

  • Page 29: Max Slave Retry

    The repeater may be programmed to either use the master's hopping pattern (selection 0) or its own (selection 1). Please refer to the Application Note on the wwww.freewave.com website.

    (8) MultiMaster Synch (8) MultiMaster Synch is reserved for applications (either point to point or multipoint) with concentrations of Master units where it is necessary to reduce interference between the Masters. Please contact FreeWave Technologies for more information. (9) 1 PPS Enable/Delay The 1 PPS Enable/Delay option allows the radio network to propagate a GPS 1PPS signal from the master transceiver to all slaves in a multipoint network.

  • Page 32 FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Note: The Subnet ID works only in Multipoint Networks using NetworkID. Note: In typical Multipoint Networks the Freq Key must be at the same setting for all transceivers. If the SubnetID is used the sub network may be set to a different Freq Key.

    FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S The drawing below depicts a Multipoint Network in which the Subnet ID is used to force communications along specific paths. In this example Repeater1 must talk directly to the Master, and Repeater2 must talk directly to Repeater1.

  • Page 34: (D) Radio Id

    FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (D) Radio ID Option (D) allows a transceiver to be designated with an arbitrary, user selectable, 4 digit number which identifies the transceiver in the diagnostics mode.

  • Page 35: Baud Rate Selections

    Transceiver(s) in the communication loop. For example, FreeWave may be used in an application to send data from remote process instrumentation to an engineer's computer. In this application the baud rate for the Transceiver on the instrumentation might be set to 9600, and the Transceiver on the computer might be set to 57,600 or 115,200.

  • Page 36: Data Word Length And Parity

    (2) Data Word Length and Parity There are six data word length and parity configurations available to be used with FreeWave transceivers. The default setting is 0 (8,N,1) and is the most commonly used serial communications protocol. Data word length and parity selections available:...

  • Page 37: Setup Port

    The Diagnostics port is a 3-pin connector. In the FGR-115RC and the FGR-115RE (Ethernet modem) this is a small 3-pin connector on the rear panel. An adapter cable for this port ((ASC0409DC) is available from FreeWave. In the FGR09xx (board level modem), this is part of a 2-row, 2 mm PCB female strip connector.

  • Page 39: Call Book Selections

    Call Book Selections (2) Edit Call Book The Call Book is an innovative feature in FreeWave which offers both security and flexibility in use. The Call Book accomplishes this by allowing the user to determine with which other FreeWave Transceivers a given Transceiver will communicate, based on the serial numbers for both the master and slave.

    Selections (1) and (2) allow the user to designate the size of the packets (in bytes) used by the transceiver in its communication link. This may be of particular value when using FreeWave with different communications software packages; you may find that throughput is optimized when packet sizes are restricted by the transceiver.

  • Page 50: Xmit Rate

    (4) RF Data Rate FreeWave has two settings for the RF Data Rate (not to be confused with the RS232 Baud Rate). Setting 2 should be used when the transceivers are close together and data throughput is to be optimized.

  • Page 51: Rf Xmit Power

    With option 6 the user may disable the transceiver’s security so it will accept a call from any other FreeWave unit. The default setting is 0 where security is enforced (the caller’s serial number must be in the slave’s Call Book), with a setting of 1 security is disabled.

    FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (8) Retry Time Out The Retry Time Out parameter allows the user to determine when a slave will drop a connection to a master or repeater in multipoint mode. The default setting is 255, meaning that if one packet in 255 from the master is sent successfully to the slave it will maintain a link.

    FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Disabling a Password The process to disable the password is similar to the process to change the password. However, when prompted to enter the new password the following procedure needs to be followed: 1.

  • Page 59: Transceiver Location

    V5.0S Transceiver Location Placement of your FreeWave unit is likely to have a significant impact on its performance. In general the rule of thumb with FreeWave is that the higher the placement of the antenna the better the communication link - height is everything! In practice you should also place the transceiver away from computers, telephones, answering machines, and other similar equipment.

    900 MHz and 2.4 GHz V5.0S Establishing Data Communication Links FreeWave's versatility allows data communication links to be established using a variety of different configurations. This, in turn, makes it possible to extend the range of FreeWave and get around obstacles.
  • Page 67 FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Diagram (C) shows a link with two repeaters between the master and slave. With two repeaters there is clearly more flexibility in getting around obstacles and greater total range is possible. Once again, it would be desirable to use external omnidirectional antennas with the repeaters, and attaching a Yagi to the master and slave would increase the range of the link.
