Spread Spectrum Wireless Data Transceiver User Manual About FreeWave Transceivers FreeWave transceivers operate in virtually any environment where RS232 data communications occur. A pair of transceivers function as a 9-pin null modem cable. If the FreeWave transceivers are to be used in an application where a null modem cable is used, such as communication between two computers, then the FreeWave transceivers can be connected directly.
Spread Spectrum Wireless Data Transceiver User Manual Choosing Point-to-Point or Point-to-MultiPoint Operation A Point-to-Point network is limited to one Master and one Slave transceiver. Up to 4 Repeaters may be added to extend the reach of the network, but no other Master or Slave may be added. In a Point-to-MultiPoint network (also referred to as MultiPoint network) the transceiver, designated as a Master, is able to simultaneously communicate with numerous Slaves.
Spread Spectrum Wireless Data Transceiver User Manual Quick Start on a Point-to-MultiPoint Network The following is a quick start guide for setting up two transceivers in Point-to-MultiPoint mode. This mode allows for a Master to communicate with several Repeaters and Slaves simultaneously. 1. Connect the transceiver to the serial port of a computer either through a serial cable or via the diagnostics cable. Make sure to connect the radio to a power source (typically, 6 to 30 VDC). 2.
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 preconfigured 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: 1. Connect the transceiver to the instrument with the RS232 cable and also attach power.
Spread Spectrum Wireless Data Transceiver User Manual 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.
Spread Spectrum Wireless Data Transceiver User Manual Setting up the Transceiver using HyperTerminal Note: The terms Modem and Transceiver are used interchangeably in this manual and in the text of the Setup menu. While the words have different meanings, the two terms should be treated as one and the same when referring to FreeWave products. Note: Included on the User Manual CD is the optional “EZConfig” transceiver setup program and instructions.

Hold DTR line asserted until the communication link between the local and remote transceiver is established over the RF channel or the protocol reports a timeout. 4. Repeat from Step 1, if needed. ASSERT AND DE-ASSERT DEFINITIONS Assert and de-assert voltage levels depend on the data port interface type.
Spread Spectrum Wireless Data Transceiver User Manual 9 000-0000 ATD_ This command does not work if Entry to Call is set to ‘All’ or if the Call Book is empty. If Entry to Call is set to ‘All’, the transceiver which received the ATD_ command will try to communicate with any Slave in the network that is listening, regardless of the serial number specified in the ATD_ command.
Spread Spectrum Wireless Data Transceiver User Manual Baud Rate This setting is the communication rate between the transceiver and the instrument to which it is connected. It is important to note that this is independent of the baud rate for the other transceiver(s) in the network. For example, a pair of transceivers may be used in an application to send data from remote process instrumentation to an engineer's computer.
Spread Spectrum Wireless Data Transceiver User Manual Baud Rate Description Actual Baud Rate (selections 0-9) The actual baud rate for the transceiver’s data port. Data, Parity (A) Modbus RTU (B) It is desirable to set the baud rate to the highest level supported by the device to which it is connected. In certain circumstances, however, this may actually result in slower data communications. Six data word length and parity configurations are available to be used with FreeWave transceivers.
Spread Spectrum Wireless Data Transceiver User Manual Setup Port (D) Note: DO NOT change this setting unless the correct programming cable is available for the new setting. This setting determines which port, Main or Diagnostics, is used to enter the Setup Main Menu. Menu Port Additional Information 1 Main Only The terminal is connected to the Main Data Port. 2 Diagnostics Only The terminal is connected to the Diagnostic Port. 3 Both Ports The terminal may be connected to either port.
Spread Spectrum Wireless Data Transceiver User Manual Call Book The Call Book is required to be used in Point-to-Point networks. While the call book is an option in Pointto-MultiPoint networks, the Network ID feature is strongly recommended in most applications. The instructions provided in this section are for Point-to-Point mode only. Use of the Call Book for MultiPoint networks is explained later in this chapter.
Spread Spectrum Wireless Data Transceiver User Manual 3. After selecting the number Enter New Number will appear. Enter the 7-digit serial number of the Slave (or Master) transceiver. 4.

The system will then prompt for Repeater 2’s number. Enter the 7-digit serial number of the second Repeater.
Spread Spectrum Wireless Data Transceiver User Manual PROGRAMMING POINT-TO-MULTIPOINT CALL BOOK In a MultiPoint network, the Slaves and Repeaters are not listed in the Master's Call Book. A Slave must have the Master and any Repeater it is going to use in its Call Book. Note: If the Network ID feature is used in a MultiPoint network, no entries are needed in the Call Book of any of the transceivers. See the Network ID feature in the MultiPoint Parameters section.
Spread Spectrum Wireless Data Transceiver User Manual Radio Transmission Characteristics The Edit Radio Transmission Characteristics option allows the user to modify several different parameters in the transceiver. Many of these parameters must be maintained throughout the network for proper functionality. Note: This menu is only for the sophisticated user who has a good understanding of the principles of radio data transmission.
Spread Spectrum Wireless Data Transceiver User Manual Available options (0) HOP TABLE VERSION Entry 0 allows the user to choose the portion of the band in which the transceiver will operate. Selection Note: Name Band 0 1 2 3 4 5 Standard Australia International Taiwan New Zealand Notch Full 902-928 MHz 915-928 MHz 902-928 MHz, 16 fewer frequencies than full U.S.
Spread Spectrum Wireless Data Transceiver User Manual (3) FREQUENCY ZONE Frequency Zone: The idea of frequency zoning is to divide the available band (902MHz to 928 MHz) into smaller bands, in this case 16 smaller bands each consisting of 5, 7, and 8 Frequency channels depending on the frequency zone. These 16 Zones are stored in a Word, which is made up of 16 bits numbered 0-15.
Spread Spectrum Wireless Data Transceiver User Manual WARNING: FCC regulations require a minimum of 50 separate frequency channels be used within a hop pattern. Using the Standard hop table, a minimum of 8 frequency zones are required for legal communication. LUM0002AF Rev D Version 6.
Spread Spectrum Wireless Data Transceiver User Manual FREQKEY IN 2.4 GHZ TRANSCEIVERS 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 pseudorandom patterns. The difference comes in the Hop Table information. (0) HOP TABLE VERSION Entry 0 allows the user to choose the portion of the band in which the transceiver will operate.
Spread Spectrum Wireless Data Transceiver User Manual (3) FREQUENCY ZONE 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. Note: The Hop Table Version must be set to 0 when using Frequency Zones.
Spread Spectrum Wireless Data Transceiver User Manual WARNING: FCC regulations require a minimum of 50 separate frequency channels be used within a hop pattern. Using the Standard hop table, a minimum of 5 frequency zones are required for legal communication. (1) MAX PACKET SIZE AND (2) MIN PACKET SIZE The Max and Min Packet Size settings and the RF Data Rate determine the number of bytes in the packets. Throughput can be enhanced when packet sizes are optimized.
Spread Spectrum Wireless Data Transceiver User Manual The following table defines the Maximum packet size in bytes by way of charting the Min Packet Size setting versus the Max Packet Size setting where the RF Data Rate is set to 3. Using the default settings, the actual maximum packet size, in bytes, is 172.
Spread Spectrum Wireless Data Transceiver User Manual (6) SLAVE SECURITY Slave security is a feature which allows Slave transceivers to accept transmissions from a Master not included in the Call Book. The default setting is 0 (Slave Security enabled) which means, only Masters in the Slaves’ Call Book may link to that Slave. Slave Security may be disabled (setting of 1) allowing any Master to call the Slave.
Spread Spectrum Wireless Data Transceiver User Manual (8) RETRY TIME OUT The Retry Time Out parameter in a Slave or Repeater sets the delay the unit will wait before dropping the connection to a Master or Repeater in MultiPoint mode. The factory default is set at the maximum of 255. The maximum setting means that if 1 packet in 255 is sent successfully from the Master to the Slave or Repeater, the link will be maintained. The minimum setting is 8.
Spread Spectrum Wireless Data Transceiver User Manual 3. To communicate to an RS232 port of a transceiver that is in Lowpower Mode, the RTS line must be held high to wake it up. The transceiver will wake up within approximately 20 milliseconds of when RTS goes high. 4. If the RTS line on the Slave is held high, the transceiver will remain in normal operation regardless of the Lowpower Mode setting. Once RTS is dropped the transceiver reverts to the Lowpower Mode. 5.
Spread Spectrum Wireless Data Transceiver User Manual Show Radio Statistics Radio Statistics in the Main Menu allows the user to view data transmission statistics gathered by the transceiver during the most recent session. This is valuable when the user needs to know the signal strength and noise levels of the link. Statistics are gathered during each data link and are reset when the next link begins. See display below.
Spread Spectrum Wireless Data Transceiver User Manual hop channel are shown in the frequency table. Pressing the Enter key when the Radio Statistics menu is displayed, accesses the frequency table. Ideally, noise levels should be below 70 J units and the difference between the average signal level and average noise level should be 26 or more. Noise levels significantly higher than this are an indication of a high level of interference that may degrade the performance of the link.
Spread Spectrum Wireless Data Transceiver User Manual (0) NUMBER REPEATERS 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. Number Repeaters needs to be set to 1 when running Diagnostics from the Master.
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. (2) MAX SLAVE RETRY The Max Slave Retry setting defines how many times (0 to 9) the Slave will attempt to retransmit a packet to the Master before beginning to use a back-off algorithm (defined by the Retry Odds setting).
Spread Spectrum Wireless Data Transceiver User Manual Without having the serial numbers in the Call Book, a Slave may establish communications with different Masters, though not at the same time. This is very useful in mobile MultiPoint applications. (8) MULTIMASTER SYNCH MultiMaster Synch is reserved for applications, in both Point-to-Point and MultiPoint modes, with concentrations of Master units where it is necessary to reduce interference between the Masters.

Spread Spectrum Wireless Data Transceiver User Manual Examples of Data Communication Links FreeWave transceivers’ versatility allows data communication links to be established using a variety of different configurations. The example below shows the most common and straightforward link; a Master communicating to a Slave in a Point-to-Point link. The example below shows how a link might be set up using a Repeater.
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.
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.
