FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Quick Start When purchased as a pair the FreeWave® Wireless Data Transceivers are shipped from the factory pre-configured to operate together in point-to-point applications. The Transceivers are preset for high-speed data communications and to communicate only with each other. FreeWave will potentially operate in virtually any environment where RS232 data communications occur.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Quick Start on a Multipoint System 0) Set Operation Mode Program one of the units to be a multipoint Master (Operation Mode 2) Program the Multipoint Slaves (Operation Mode 3) 1) Set Baud Rate Set the Baud Rate to match the baud rate of the device to which the transceiver will be connected.
FreeWave Technologies Spread Spectrum Transceiver User Manual 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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Operation Mode Selections (0) Point-to-Point Master As mentioned previously, FreeWave operates in a Master/Slave configuration. When designated as a master in point-to-point mode the Transceiver will call any or all slaves it is instructed to call in the Call Book.
FreeWave Technologies Spread Spectrum Transceiver User Manual 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. All settings for the call book, baud rate, and radio transmission characteristics are disabled.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Using Mode 6 to call a transceiver not listed in the Call Book Mode 6 will accept the command ATD####### where ####### is any arbitrary modem serial number such as 5551234. Upon receipt of this command the modem will call that modem even though the number is not in the sending modem’s Call Book.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S 2. Issue the command ATXC# where # corresponds to the position in the Call Book where the repeater(s) is/are located 3. Issue the command ATD####### where ####### is the serial number of the transceiver with which you are attempting a link. The transceiver will link first to the repeater(s) specified and then to the slave transceiver. 4.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Multipoint Operation Theory of Operation In a Multipoint system a transceiver designated as a master is able to simultaneously be in communication with numerous slaves. In its simplest form, a Multipoint network functions with the master broadcasting its messages to all slaves and slaves responding to the master when given data by the device connected to the RS232 port.
FreeWave Technologies Spread Spectrum Transceiver User Manual 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.
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. Therefore it is important to find the optimal mix between system robustness, throughput, and latency.
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. Therefore, the repeater will send the packet out the number of times corresponding to its Master Packet Repeat parameter.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (2) Max Slave Retry (3) Retry Odds While packets transmitted from the master to the slaves in a Multipoint network are not acknowledged, packets transmitted from slaves to the master are. However, it is possible that more than one slave will attempt to transmit to the master at the same time, and it is therefore important that a protocol exists to resolve contention for the master between slaves.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (6) NetWork ID Option (6) NetWork ID allows multipoint networks to be established without the use of the Call Book. If the NetWork ID is set to any value other than the default (255) and no higher than 4095 the slaves in the multipoint network will communicate with the first multipoint master or repeater heard with the same NetWork ID.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (A) Slave/Repeater The Slave/Repeater mode allows a transceiver in a multipoint system to simultaneously act as a slave and a repeater. When in this mode a transceiver will repeat any packets sent from a master as well as send them out the RS232 port. Thus where 2 transceivers would be necessary previously (one to repeat and one to be a slave) only one is now needed.
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. Note: If both Rcv SubnetID and Xmit SubnetID are set to 0 the SubnetID will show Roaming in the menu.
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. Communications for Slaves 1, 2, and 3 are forced along the direction of the solid lines, and Slave4 may link to the first Master or Repeater it hears.
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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Baud Rate Selections (1) Set Baud Rate When item (1) is selected you will be able to change the Transceiver's RS232 baud rate - 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 communication loop.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S The Baud Rate section of the user interface provides two other important parameters, the ability to change the transceiver's word length and to put it into ModBus RTU mode. (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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S port. In TTL RF board products (FGR09Tx) and Ethernet products (FRG-115RE), this setting must be "0". Table 5: Data port protocol Selections Default is 0 (RS232 or TTL). Menu Setting 0 1 2 3 Protocol RS232 RS422 RS485 DOT Notes Use this for TTL RF boards and Ethernet modems You must turn on ModBUS RTU mode.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Flow Control Use this menu to specify the hardware flow control for the Data port. Table 7: Flow control Selections Menu Setting 0 1 2 Port None RTS DTR Notes Use software control (XON XOFF) Default is 0 (no hardware flow control).
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S 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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Figure 7: Call Book Menu Entering or Modifying numbers in the Call Book Entering or modifying serial numbers in the Call Book is a straightforward process. When in the Call Book menu enter the position number (0 - 9) you wish to edit. You will be prompted for the new number (formatting is automatic, you do not need to enter the dash).
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Programming the Call Book to Use 3 or 4 Repeaters In a point to point link FreeWave can utilize up to 4 repeaters. To use 3 or 4 repeaters program the Call Book with the slave being called, followed by the first 2 repeaters being used (from the master calling out to the slave). In the next position in the Call Book enter 999-9999 as the number to call.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Programming The Call Book in Multipoint Systems In a Multipoint system the slaves and repeaters are not listed in the master's Call Book. When establishing such a system, it is necessary only to have the master's serial number in each slave's and repeater's Call Book, and to have each repeater's serial number in the Call Book of each slave which may potentially communicate through it.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Radio Transmission Parameters (3) Edit Radio Transmission Characteristics When item (3) is selected in the main menu the screen in figure 9 appears, which allows the user to modify the radio transmission characteristics of the Transceivers. As stated in the warning, these parameters are for the sophisticated user who has a good understanding of the principles of radio data transmission.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (0) FreqKey Selection (0) in the Radio Parameters menu allows the user to modify the hopping patterns of the Transceivers to minimize the interference with other FreeWave Transceivers in operation in the area.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (0) Hop Table Version Entry 0 allows the user to choose the portion of the band in which the transceiver will operate.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S 2.4GHz The Frequency Key for the FreeWave Technologies 2.4GHz transceivers offers the ability to select more than just a different pseudo random hop table, but also the portion of the band which the transceiver will use.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Figure 11: Frequency Key & Hop Table Options, 2.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (1) Max Packet Size and (2) Min Packet Size 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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (3) Xmit Rate There are two settings for the Transmit Rate parameter. For normal operation FreeWave should be set at Transmit Rate 1. Transmit Rate 0 is useful to qualitatively gauge signal strength. When set to Transmit Rate 0 the Transceivers will transmit data back and forth continuously, and the strength of the signal may be gauged by the Clear to Send LED.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S (5) RF Xmit Power (6) Slave Security 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. The lowest setting is 8, at which a slave will drop a connection much more quickly.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S the table gives only qualitative indication of savings of supply current. Set this setting to empirically, considering that a low number reduces latency, and a high number reduces current consumption.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Radio Statistics Option (4) in the main menu allows the user to view data transmission statistics which have been gathered by the Transceiver during the most recent session. This is of value when the user wishes to look at signal strength, noise levels, and the distance of the link between transceivers. Statistics are gathered during each data link and are reset when the next link begins.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Average noise levels will typically fall in the range of 15 to 30. Average noise levels significantly higher than this are an indication of a high level of interference that may degrade the performance of the link. High noise levels can often be improved with bandpass filters, antenna placement or antenna polarization. Please contact FreeWave Technologies for more information.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Radio Temperature The radio temperature value is the current operating temperature of the radio in degrees C (Celsius.) For proper operation, FreeWave radio modems must be in the range of –40° to 75°C.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Password MMMMM Caution!!! If the password feature is enabled and you cannot remember the password the radio will need to be sent back to FreeWave to have the password disabled. Option (8) in the Main Menu allows the user to set a password which will prevent access to or changing of any of the radio’s parameters.
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. Hold down the Alt key and type 0255 2. Release the Alt key 3. Repeat this step 3 more times (hold Alt and type 0255 a total of 4 times).
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz 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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Front Panel LEDs The LEDs on FreeWave's front panel provide important information on the operation of the transceiver. Compare the status of a Transceiver's LEDs with the table below to aid you in the troubleshooting process.

FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Pin 8: Clear to Send (CTS) This signal is used to tell the system device connected to the modem that the modem is ready to receive data. When asserted, the modem will accept data, when deasserted the modem will not accept data. This should always be used for data rates above 38.4KB or there will be a risk of lost data if an RF link is not very robust.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S FGRO RF Board only Pinout The FGRO Small Footprint Series transceivers are available in both TTL and RS232 versions. The TTL versions use reverse polarity from standard RS-232 at 0 to 5 Volt levels. All pin descriptions and pin numbering are the same as the RS232 version.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.
FreeWave Technologies Spread Spectrum Transceiver User Manual 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. Diagram (A) shows the most common and straightforward link, a master communicating to a slave in a dedicated link.
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.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S Example (E) depicts a standard point-to-multipoint system. In this example any data sent from the master is broadcast to all three slaves, one of which receives it through a multipoint repeater. The data is in turn sent out of the RS232 port of each of the three slaves.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S In (F) a point-to-multipoint system is depicted which uses one of the slave sites as a repeater simultaneously, all through the same radio. This system works in a manner very similar to a standard multipoint system with repeaters, however the number of radios needed is reduced with the use of the multipoint slave/repeater feature.
FreeWave Technologies Spread Spectrum Transceiver User Manual 900 MHz and 2.4 GHz V5.0S RS422 & RS-485 Operation For both RS-422 and RS-485 the Freewave modem can drive 32 standard unit loads and loads the buss with only 1/8 unit load. This means the user can tie up to 256 devices on the buss if all of the line receivers have 1/8 unit load (different devices have different loads). RS-422 is used for full duplex (4 wire) communication with one master and many slaves.
