LRS455-C-U, -T-U, CE-U, TE-UUser & Reference Manual1. IntroductionFreeWave radios operate in virtually any environment where serial data communications occur. Apair of radios functions as a 9-pin null modem cable.lIf the FreeWave radios are to be used in an application where a null modem cable is used,such as communication between two computers, then the FreeWave radios can beconnected directly.lIf FreeWave radios are to be used to replace a straight-through RS232 cable, then a nullmodem cable must be placed between the radio (DCE) and the DTE instrument to which itis connected.Figure 1: LRS455 Wireless Data RadioLUM0016AB Rev May-2018 Page 9 of 90 Copyright © 2018FreeWaveThis document is the property of FreeWave Technologies, Inc. and contains proprietary information owned byFreeWave.

1. Introduction LRS455-C-U, -T-U, CE-U, TE-UUser & Reference ManualLUM0016AB Rev May-2018 Page 10 of 90 Copyright © 2018FreeWaveThis document is the property of FreeWave Technologies, Inc. and contains proprietary information owned byFreeWave. This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Warning! Do not connect the LRS455-C-U, -T-U, CE-U, TE-U series radios to DC powerwithout terminating the antenna port to a suitable load, such as a 50 ohm antenna, or anattenuator with a power rating greater than or equal to 2 W. Powering up without a load attachedwill damage the radio and void the warranty.1.1. Choosing a Location for the RadiosPlacement of the FreeWave radio is likely to have a significant impact on its performance. The keyto the overall robustness of the radio link is the height of the antenna. In general, FreeWave unitswith a higher antenna placement will have a better communication link. In practice, the radioshould be placed away from computers, telephones, answering machines, and other similarequipment. The cable included with the radio usually provides ample distance for placement awayfrom other equipment. FreeWave offers directional and Omni-directional antennas with cablelengths ranging from 3 to 200 feet. When using an external antenna, placement of that antenna iscritical to a solid data link. Other antennas in close proximity are a potential source of interference.Use the Radio Statistics to help identify potential problems.The Show Radio Statistics page is found in option 4 in the main Setup menu or in the Diagnosticinformation in Tool Suite. An adjustment as little as 2 feet in antenna placement can resolve somenoise problems. In extreme cases, such as when interference is due to a Pager or CellularTelephone tower, the band pass filters that FreeWave offers may reduce this out-of-bandnoise.1.2. Choosing Point-to-Point or Point-to-MultiPoint OperationNote: In an LRS455-C-U, -T-U, CE-U, TE-U radio network, you can use only one Repeater.A Point-to-Point network is best suited when your network consists of one Master and one Slaveradio.Important!: Adding a Repeater to a network reduces the throughput by 50%. For example, over-the-air throughput in a network running at 2-Level GFSK and with the Repeaters parameter disabled is9600 bps. With the Repeaters parameter enabled, the over-the-air throughput drops to 4800 bps.The LRS455-C-U, -T-U, CE-U, TE-U radios are narrowband radios and have a limited channel sizebased on the license obtained from the FCC. Therefore, the radios can experience a dramatic impactin throughput if a Repeater is implemented in the network. If you have large amounts of data totransfer and choose to add a Repeater in your network, you must optimize polling host / RTUsettings to accommodate for the lower throughput. Polling host / RTU optimization settings includereducing block/packet sizes and increasing overall time-out parameters.In a Point-to-MultiPoint network (also referred to as MultiPoint network), the Master radio is ableto simultaneously communicate with numerous Slave radios. In its simplest form, a MultiPointnetwork functions with the Master broadcasting its messages to all Slaves. If requested by theMaster, the Slaves respond to the Master when given data by the device connected to the dataport. This response depends on your setup. You can extend the reach of a licensed network with

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.one Repeater. As with a Repeater in a Point-to-Point network, adding a Repeater to a networkcuts the data throughput by half.It is important to note the differences between Point-to-Point and MultiPoint networks. In a Point-to-Point network all packets are acknowledged, whether sent from the Master to the Slave or fromthe Slave to the Master. In a MultiPoint network, you determine the number of times outboundpackets from the Master or Repeater to Slaves are sent. The receiving radio, Slave or Repeater,accepts the first packet received that passes the 32 bit CRC. However, the packet is notacknowledged. On the return trip to the Master, all packets sent are acknowledged orretransmitted until they are acknowledged. Therefore, the return link in a MultiPoint network isvery robust.Traditionally, a MultiPoint network is used in applications where data is collected from manyinstruments and reported back to one central site. The architecture of such a network is differentfrom Point-to-Point applications. The following parameters influence the number of radios thatcan exist in a MultiPoint network:1. Size of the blocks of data. The longer the data blocks, the fewer number of deployed Slavescan exist in the network.2. Baud rate. The data rate between the radio and the device to which it is connected couldlimit the amount of data and the number of radios that can exist in a network3. The amount of contention between Slaves. Polled Slaves vs. timed Slaves.4. Use of a Repeater. Using the Repeaters setting in a MultiPoint network decreases overallnetwork capacity by 50%.Example: If the network polls Slaves once a day to retrieve sparse data, several hundred Slavescould be configured to a single Master. However, if each Slave transmits larger amounts of data ordata more frequently, then fewer Slaves can link to the Master while receiving the same networkperformance. When larger amounts of data are sent more frequently, the overall network bandwidthis closer to capacity with fewer Slaves.For examples and additional information about data communication links, see the DataCommunication Links section.1.3. Data Communication Link ExamplesFreeWave radios' versatility allows data communication links to be established using a variety ofdifferent configurations.1.3.1. Point to Point LinkThe example below shows the most common and straight forward link; a Master communicatingto a Slave in a Point-to-Point link.Figure 2: Point to Point Link

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.1.3.2. Repeater LinkThe example below shows how a link might be set up using a Repeater. The Repeater may belocated on a hilltop or other elevated structure enhancing the link from the Master to the Slave.Inthis configuration, it may be desirable to use an external Omni directional antenna at theRepeater.Yagi antennas may be used at both the Master and Slave radios.In an LRS455-C-U, -T-U, CE-U, TE-U radio network, you can use only one Repeater.Figure 3: Repeater LinkImportant!: Adding a Repeater to a network reduces the throughput by 50%. For example, over-the-air throughput in a network running at 2-Level GFSK and with the Repeaters parameter disabled is9600 bps. With the Repeaters parameter enabled, the over-the-air throughput drops to 4800 bps.The LRS455-C-U, -T-U, CE-U, TE-U radios are narrowband radios and have a limited channel sizebased on the license obtained from the FCC.

If you have large amounts of data totransfer and choose to add a Repeater in your network, you must optimize polling host / RTUsettings to accommodate for the lower throughput. Polling host / RTU optimization settings includereducing block/packet sizes and increasing overall time-out parameters.1.3.3. Point to Multipoint NetworkThe next example depicts a standard Point-to-MultiPoint network. From the Master, any data isbroadcast to all three Slaves, one of which receives it through a MultiPoint Repeater. The data isin turn sent out of the serial port of each of the three Slaves. The end device should be configuredto interpret the serial message and act on it if necessary.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Figure 6: Serial Number Location for Non-Enclosed Model1.5. Powering the RadioTo provide power to the radio, connect it to a positive supply with +6.0 to +27.0 VDC (typically,+12VDC).Using a dedicated power supply line is preferred. The power supply you use must provide morecurrent than the amount of current drain listed in the product specifications listed in the product'sdata sheet available on www.FreeWave.com for the voltage you are using. For example, if youare using +12.0VDC, the power supply must provide above the drain that is required for transmitusing +12 VDC.Warning! Do not connect the LRS455-C-U, -T-U, CE-U, TE-U series radios to DC powerwithout terminating the antenna port to a suitable load, such as a 50 ohm antenna, or anattenuator with a power rating greater than or equal to 2 W. Powering up without a load attachedwill damage the radio and void the warranty.If the power supply line runs outside the radio enclosure, use electrostatic discharge (ESD)protectors to protect the radio from electric shock, and transient voltage suppressors (TVS) toprotect from an over-voltage situation. Using both helps to ensure long-term, reliable operation.FreeWave does not supply or sell these items; however, they can be purchased at most electronicsupply stores.1.6. Configuration Tool OptionsNote: The terms modem and radio are used interchangeably in this document and in the text withinthe setup tools. While the words have different meanings, the two terms should be treated as oneand the same when referring to FreeWave products.When the radio is in Setup mode, you can use the following setup tools to configure the settings onthe radio:lTool Suite - provides a group of tools for configuring the devices in your network and formonitoring your network's performance. Using the Configuration application within ToolSuite, you can program changes to your radio's settings.lTerminal Emulator - A terminal emulator program, e.g., TeraTerm, offers many of thesame configuration options that are available in the Configuration application in Tool Suite.

TheSetup Terminal application in Tool Suite provides the same interface that is availableusing a terminal emulator.1.6.1. Tool Suite and Terminal EmulatorsIf using a terminal emulator, the tabs for a device in Tool Suite mirror the Setup main menuselections.Example: Option 0from the Setup main menu in the terminal menu setup is Set Operation Mode.The corresponding configuration tab for the device in Tool Suite is (0) Operation Mode.Figure 7: Tool Suite and Setup MenuYou can also use the Setup Terminal application within Tool Suite to use and view the terminalmenus. It displays the same menus and provides the same programming settings as you seeusing a terminal emulator.Throughout this document, if the setup procedure in the terminal emulator is different than theprocedure in Tool Suite, the terminal instructions are also included.1.7. Radio Setup ModeTo read the current settings from or to program a radio, the radio must be in Setup mode. When aradio is in Setup mode, all three LEDs display solid green . See the sections below fordetails about how to access the radio's Setup mode using Tool Suite or a terminal emulator.Note: OEM boards may also enter Setup when Pin 2 on a 10-point connector or Pin 8 on a 24-pinconnector is grounded, or using a break command. For more information about the break command,see Use Break to Access Setup (on page 28).The Setup Port (on page 26) parameter in the Baud Rate tab determines whether the main dataport or the diagnostics port is used to access the setup parameters for the radio.

If connected to the diagnostics port, type U(Capital ‘U’) to invoke theSetup menu.To display the Setup menu in board level radios:lShort pins 2 & 4 (Brown to Black) on the 10 pin header next to the LEDs.lIf using a data cable (FreeWave Part Number: ASC3610DB or ASC3610DJ), pressthe Setup button.lIf using the gray ribbon diagnostic cable (FreeWave Part Number: AC2009DC) or theblack diagnostic cable (P/N ASC0409DC), type <Shift+U> to activate the Setup menu.When Setup is activated, the FreeWave Setup Main Menu shows in the terminal emulatorwindow. All three LEDs on the radio light green and stay green as long as the radio is inSetup mode. The main setup menu appears.Important!: As you navigate through the Setup menu and make changes to the parameters, theparameters are sent to the radio immediately.1.7.3. Troubleshooting Terminal EmulatorsThese are some common issues encountered while using terminal emulators:Nothing displays on the screen after placing the radio into Setup mode.This usually indicates one of two things; either the wrong Com port is selected or a nullmodem cable is being used. Change the Com port, verify the cable, and attempt toconnect again.In addition, if the radio has been previously configured, you could be using the wrongport to access the Setup menu. For more information, see Setup Port (on page 26).Tryconnecting to the other port.Unreadable characters display on the screen after placing the radio into Setup mode.This typically indicates a baud rate mismatch. Unreadable characters beforegrounding the pin indicates Diagnostics is enabled and the terminal emulator isconnected to the Diagnostics pins. Update the terminal emulator's baud rate to 19200and reconnect to the radio.

Update the terminal emulator's flow control setting to None and reconnect to theradio.A connection exists, the terminal emulator is receiving data, and some data is correct,but the remaining data is in unrecognizable characters.This usually indicates a parity mismatch. Ensure that the parity of the radio and theparity of emulator are are set the same.1.8. Upgrading Radios to the Latest FirmwareIf Tool Suite is connected to a radio, and a new version of the firmware is available for that radiomodel, an indication displays within the Configuration application's Device Information tab. Youcan use Tool Suite to upgrade firmware on a serial radio that is connected directly to the computerusing the diagnostic cable. You cannot complete an over-the-air upgrade using Tool Suite.Note: If you are using a USB-to-serial converter cable, a firmware upgrade can take a long time tocomplete. FreeWave recommends using only USB-to-serial cables that include the FTDI Chip Set.This inclusion is listed on the cable's packaging.Use the steps below to upgrade a radio to the latest firmware:1. With the radio connected to your computer through the Com port, open Tool Suite and clickConfiguration in the Applications pane to display the Configuration application.2. Click Upgrade Radio in the Firmware section of the Configuration ribbon.3. Click Yes at the prompt to proceed or No to cancel without installing the new firmware.Tool Suite identifies and displays the firmware version that is loaded on the connecteddevice and displays the latest version of firmware available for that model.4. Click Yes to proceed with the upgrade, or No to exit.The system displays the progress of the firmware upgrade. After the firmware upgrade iscomplete, a message displays that the firmware upgrade was successful.
LRS455-C-U, -T-U, CE-U, TE-UUser & Reference Manual2. Basic Radio Programming and SetupAs you set up your network, whether it be a Point-to-MultiPoint network or a Point-to-Pointnetwork, the process for setting up and programming a radio is the same. This chapter describesthe following aspects of programming and setting up a radio, regardless of the network type:lSetting the radio's role in the network, and the network type.lEntering parameters that establish communication with the instrument or computer towhich the radio is connected.lEstablishing communication with other radios in the network.lSetting data transmission characteristics.2.1. Setting the Radio's Role in the Network and the NetworkTypeRadio networks consist of a Master and any number of other components including Repeaters,Slave radios, and radio's that act as both Slave and a Repeater radio. The first parameter to set ina radio is to select its Operation Mode or Modem Mode. The mode tells the radio what networktype it is in (Point-to-Point or Point-to-MultiPoint) and what role it plays, Master, Slave, orRepeater, in that network.Note: The network type must match for all radios in a network. For example, if you are configuring aPoint-to-MultiPoint network, ensure the Modem Mode selection for radios in the network starts withPoint-to-MultiPoint.In a Point-to-Point configuration, Master or Slave mode may be used on either end of thecommunication link without performance degradation. When setting up the radio, remember thatthe settings on the Master control a number of parameters. Therefore, deploying the Master onthe communications end where it is easier to access is advised, but not necessary.LUM0016AB Rev May-2018 Page 20 of 90 Copyright © 2018FreeWaveThis document is the property of FreeWave Technologies, Inc. and contains proprietary information owned byFreeWave.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Set the Modem Mode in the Operation Mode tab, using the Modem Mode field. These settingsare available in the Operation Mode menu in the terminal interface. Select from these options:Operation Mode DescriptionPoint-to-Point Master(0)This mode designates the radio as the Master in Point-to-Point mode. TheMaster may call any or all Slaves designated in its Call Book.In Point-to-Point mode the Master determines the setting used for most of theradio transmission characteristics, regardless of the settings in the Slaveand/or Repeater. The settings not determined by the Master are:lTransmit PowerlSlave SecuritylRetry Time OutlHop Table settingsTo identify a Master, power the radio. Prior to establishing a communicationlink with a Slave, all three of the Master's LEDs are solid red.Point-to-Point Slave(1)This mode designates the radio as a Slave in Point-to-Point mode. The Slavecommunicates with any Master in its Call Book—either directly or throughone Repeater.When functioning as a Slave, the Entry to Call feature in the radio’s Call Bookis not operational.Set Slave Security to 1to bypass the Call Book in the Slave. For moreinformation, see Slave Security (on page 37).Point–to-MultiPointMaster (2)This mode designates the radio as a Master in MultiPoint mode. This modeallows one Master to communicate simultaneously with numerous Slaves.A Point-to-MultiPoint Master communicates only with other radiosdesignated as Point-to-MultiPoint Slaves or Point-to-MultiPoint Repeaters.Point-to- MultiPointSlave (3)This mode designates the radio as a Slave in MultiPoint mode. This modeallows the Slave to communicate with a MultiPoint Master. The Slave maycommunicate with its Master through one Repeater.Point-to-PointSlave/Repeater (4)This mode designates the radio to act as either a Slave or Repeater—depending on the instructions from the Master. The radio cannot act as both aSlave and a Repeater at the same time. True Slave/Repeater functionality isonly available in a MultiPoint mode.Point-to-Point Slave/Repeaters have no security features. When a radio isdesignated a Point-to-Point Slave/Repeater, it allows any Master to use it asa Repeater.Point-to-PointRepeater (5)A network using LRS455-C-U, -T-U, CE-U, TE-U radios can have oneRepeater in a Point-to-Point communications link, to extend the operatingrange. When designated as a Repeater, a radio behaves as a pass-throughlink. All settings for the Call Book, baud rates, and radio transmissioncharacteristics are disabled. A Repeater connects with any Master that callsit. The Repeater must be set up properly in the Master's Call Book.

Additionally, when the Point-to-Point Slave/Master Switchableoption is selected and the radio is not calling a Slave, it functions as a Slaveand accepts any appropriate calls from other radios.For more information, see Application Note #5476, Mode 6.Point-to-MultiPointRepeater (7)This mode allows the radio to operate as a Repeater in a MultiPoint network.You can have one Repeater in an LRS455-C-U, -T-U, CE-U, TE-U network.Ethernet Options (F) This menu applies to Ethernet radios only. Although the menu is includedhere, it is unrelated to this radio.2.2. Establishing Communication with Instrumentation andComputersThe settings in the Baud Rate tab are the communication settings between the radio and theinstrument or computer to which it is connected (radio serial port to the device). These settings areunique to each radio, and do not need to match across the network.For example, a pair of radios may be used in an application to send data from remote processinstrumentation to an engineer's computer. In this application, the baud rate for the radio on theinstrumentation might be set to 9600, and the radio on the polling host might be set to 57,600.Set the following parameters in the Baud Rate tab. These settings are available in the Baud Ratemenu in the terminal interface, and apply to both Point-to-Point and Point-to-MultiPoint networks.2.2.1. Baud RateBaud RateSetting DescriptionDefault Setting 115200Options 1200, 2400, 4800, 9600, 19200, 38400, 57600, 76800, 115200, 230400Setup TerminalMenu(1) Set Baud Rate

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Baud RateSetting DescriptionDescription This is the actual baud rate for the radio’s data port.lThis setting is the communication rate between the radio and the instrument towhich it is connected, and is independent of the baud rate for the other radiosin the network.lSet the baud rate to the highest level supported by the device to which it isconnected.lWith a poor radio link, however, this may actually result in slower datacommunications.Example: A pair of radios may be used in an application to send data fromremote process instrumentation to the engineer's computer. In thisapplication, the baud rate for the radio on the instrumentation might be setto 9600, and the radio on the engineer's computer might be set to 57,600.FREEWAVE Recommends: With a Baud Rate setting of 9600 or higher,FreeWave recommends using the Flow Control lines. For moreinformation, see Flow Control (on page 24).Note: The setup port Baud Rate always defaults to 19,200 regardless ofhow the data port Baud Rate is set. The only exception is Mode 6.

This setting can be used with severaldifferent timing sensitive protocols, such as Modbus RTU and DNP3. A settingother than 0causes the radio to wait for an amount of time “gathering” data beforesending out the radio link.lWhen set to 0(Disabled), the radio sends data out through its radio link assoon as the data is received into the serial port.lWhen set to 1, the radio waits for a number of slots equal to two times theMaster Packet Repeat setting before waits for 6 slots, gathering data up thewhole time. At the end of the 6 slots, the radio sends all received data in one“burst.” This is the appropriate setting for most Modbus RTU devices.lWhen set to 2and higher, the radio waits for a number of slots calculatedusing the following formula:(Modbus RTU setting + Master Packet Repeat setting + 1) x 2Example: In a radio where the Modbus RTU setting is 2and the MasterPacket Repeat setting is 3, the radio waits for (2 + 3 + 1) x 2, or 12 slots.2.2.5.

Establishing Communication with Other Radios in theNetworkFor the radios in your network to communicate successfully, you need to tell the radios what otherdevices are available for them to communicate. Use one of the following options:lNetwork ID - Used in MultiPoint Networks, the Network ID parameter is available in theMultiPoint Parameters tab. Each radio in a single network should be assigned the samenetwork ID. A Slave links with the first Master or Repeater that it hears that has a matchingNetwork ID.Because the Network ID does not use serial numbers, MultiPoint Masters and Repeaters maybe replaced without reprogramming all of the Slaves in the network. The Network ID function

This is very useful in mobile MultiPoint applications.For information about setting the Network ID parameter in a MultiPoint Network, see Using theNetwork ID in MultiPoint Networks (on page 47).lCall Book - The Call Book is required in Point-to-Point networks.lThe Call Book stores serial numbers of radios in the network that are allowed to talk to aradio.lUsing the Call Book offers both security and flexibility in determining how FreeWaveradios communicate with each other.Important!: While the Call Book is an option in Point-to-MultiPoint networks, FreeWave stronglyrecommends using the Network ID feature in most applications. If a large MultiPoint network isimplemented using the Call Book and you want to add a radio to the network, or need to replace aradio, you must physically reprogram each radio in the network and enter the new serial number inthe radio's Call Book. This can be a time consuming process and can cause a delay in getting yournetwork back up and running.For more information about defining the Call Book in a Point-to-Point network, see Using theCall Book in Point-to-Point Networks (on page 66). For more information about defining theCall Book in a Point-to-MultiPoint network, see Using the Call Book in MultiPoint Networks (onpage 47).2.3.1. Golden SettingsA standard network requires that the following parameters are set the same on all radios in thenetwork. FreeWave refers to these as the Golden Settings.lRx FrequencylTx FrequencylMin Packet SizelMax Packet SizelNetwork IDlRF Data RateRadios that contain the same settings in all these parameters can communicate with each other. Ifyou choose to use the Call Book instead of the Network ID, or are running a Point-to-Pointnetwork, the appropriate serial numbers must be listed in the Call Book for each radio.2.4. Setting RF Transmission CharacteristicsThe Transmission Characteristics parameters allow you to modify settings that determine howdata is sent between radios in your network. Many of these parameters must be maintainedthroughout the network for proper functionality.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Retry TimeoutSetting DescriptionDescription The Retry Time Out parameter in a Slave or Repeater sets the delay the unitwaits before dropping the connection to a Master or Repeater.lThe maximum setting means that if 1 packet in 255 is sent successfully fromthe Master to the Slave or Repeater, the link is maintained.lThe minimum setting is 8.lThis allows a Slave or Repeater to drop a connection if less than 1 in 8consecutive packets is successfully received from the Master.lThe function in the Master is effectively the same. With a setting of 255, theMaster allows a Slave or Repeater to stay connected as long as 1 packet in255 is successfully received at the Master.The Retry Time Out parameter is useful when a MultiPoint network has a rovingMaster or Slave(s). As the link gets weaker, a lower setting allows a poor link tobreak in search of a stronger one.Setting Retry Time Out to 20 is recommended in areas where several FreeWavenetworks exist. This recommended setting allows Slaves and Repeaters to dropthe connection if the link becomes too weak, while at the same time prevent errantdisconnects due to interference from neighboring networks.While intended primarily for MultiPoint networks, the Retry Time Out parametermay also be modified in Point-to-Point networks. However, the value in Point-to-Point mode should not be set to less than 151.2.4.6. RF Data RateNote: In MultiPoint networks, the RF Data Rate must be identical in all radios. Any radio with an RFData Rate different from the Master will not establish a link. In Point-to-Point networks the Master’ssettings take precedence over the Slave.RF Data RateSetting DescriptionDefault Setting (4) 12.5 kHz 4 levelOptions l(4) - With an occupied bandwidth of 12.5 kHz and modulation level of 4-levelGFSK. With an RF Data Rate of 4, the maximum over-the-air operating speedis 19,200 bps.Important!:RF Data Rate 4 is not compatible with firmware versions 1.69and older.l(5) - With an occupied bandwidth of 12.5 kHz and a modulation level of 2-levelGFSK. With an RF Data Rate of 5, the maximum over-the-air operating speedis 9600 bps.

Overlapping MultiPoint NetworksOverlapping MultiPoint networks may be set up effectively with FreeWave radios when severalkey parameters are set correctly. Overlapping MultiPoint networks are defined as networks usingdifferent Master, which share or overlap in a specific geographic area.Co-located MultiPoint networks require the following parameters be unique for each network:lNetwork ID, unless using the Call BooklMax Packet SizelMin Packet SizeNote: For more information about the installation of Point-to-MultiPoint networks, contact FreeWaveTechnical Support.3.4. Establishing Communication with Other Radios in aMultiPoint NetworkFor the radios in the network to communicate successfully, tell the radio what other devices areavailable for them to communicate with. You can use the Network ID or the Call Book.FREEWAVE Recommends: Use the Network ID option instead of the Call Book in MultiPointnetworks. Because the Network ID does not use serial numbers, MultiPoint Master and Repeatersmay be added or replaced without reprogramming all of the Slave in the network.3.4.1. Using the Network ID in MultiPoint NetworksThe Network ID parameter is located in the MultiPoint Parameters tab. A radio from the factoryhas a Network ID setting of 255, which enables the Call Book. Assign each radio in a singlenetwork the same Network ID. The Slave links with the first Master or Repeater it hears that hasa matching Network ID.Keep the following in mind when setting the Network ID:lThe value can be any value between 0 and 4095, NOT 255.lTo help ensure your ID is unique to your network, avoid using numbers that coincide withnearby landmarks or highways.lFreeWave recommends a Network IDof four characters.lFor example, the last four digits of the Master's serial number, which is ensured to beunique and does not overlap with other nearby FreeWave networks.lUse the Network ID function in conjunction with the Subnet ID feature (if necessary) toroute data through the radio network.3.4.2. Using the Call Book in MultiPoint NetworksAlthough not recommended, the Call Book is an option in MultiPoint networks. If the Network IDfeature is used in a MultiPoint network, no entries are needed in the Call Book of any of the radios.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.FREEWAVE Recommends: Use the Network ID feature in a MultiPoint network. Using the CallBook in a MultiPoint network can cause delay in resuming communication if a Master is damaged.Note: For information about setting the Call Book, see Using the Call Book in Point-to-PointNetworks (on page 66).In a MultiPoint network, the Slaves and Repeater are not listed in the Master's Call Book. A Slavemust have the Master and the Repeater it is going to use in its Call Book.These examples show the Call Books of a MultiPoint network comprised of a Master, Repeater,and Slave in which the Slave can communicate either through the Repeater or directly to theMaster:MultiPoint Master Call Book (Unit Serial Number 900-0001)Entry Number Repeater 1(0) 000-0000(1) 000-0000No serial number entries are necessary in the Master’s Call Book.MultiPoint Repeater Call Book (Unit Serial Number 900-0002)Entry Number Repeater 1(0) 900-0001(1) 000-0000MultiPoint Slave Call Book (Unit Serial Number 900-0003)Entry Number Repeater 1(0) 900-0001(1) 900-0002(2) 000-0000At times, you may want to force a Slave to go through a specific MultiPoint Repeater. In thisscenario, the Slave’s Call Book should contain only the serial number for that Repeater as theentry on line 0.3.5. Routing Communication Through the NetworkWhen using the Network ID feature, a Repeater or Slave links to the first Repeater or Master ishears with the same ID. Using subnet IDs, you can determine the path a Repeater or Slave usesto communicate back to the Master.By forcing the communication path, you can optimize performance of the network by ensuring theRepeater or Slave links to a Repeater or Master with robust RF communications. Subnet IDs canhelp to minimize latency. By designing paths in a network, you can create the most efficientcommunication paths.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.3.5.1. Assigning Subnet ID ValuesSubnet IDs consist of two parts, both available in the Multipoint Parameters tab:lRx - This setting identifies which radio a Repeater or Slave listens to. In the terminalinterface, this is the Rcv Subnet ID.lTx - This setting identifies the ID on which this device transmits, and in turn which deviceslisten to it. The Tx Subnet ID parameter is relevant for Multipoint Master radios andRepeaters only. In the terminal interface, this is the Xmt Subnet ID.The default (disable) setting for both Rx and Tx is F, which is a visual way to indicate that thedevice is the final in the line of communication and does not use a subnet ID. A Multipoint Slavewith a Subnet ID of F,F does not roam from one Repeater or network to the next, it only links to aMaster or Repeater that has either a Tx setting of 0 or an F,F Subnet ID.Setting both Rx and Tx Subnet ID to 0 allows a mobile Slave to roam from subnet to subnet, andpossibly from network to network, provided the Network ID, Max and Min Packet Size, and RFData Rates are the same between networks.The examples in this section show the subnet definitions from the Master radio through thenetwork to the Slave radios. When the subnet path is defined, the Slave radios can follow theroute back to the Master.In the following example, the Repeater and Slave 1 must talk directly to the Master. Slave 2 andSlave 3 must talk directly to the Repeater. Slave 4 may link to the Master or Repeater, whichever ithears first in the network.Figure 11: Repeater and Slave 1 Must Talk Directly to the Master

Setting Other MultiPoint ParametersThe other MultiPoint Parameters options allow you to modify several different parameters in theradio that determine the characteristics of a MultiPoint network.Set the following parameters in the MultiPoint Parameters tab. These settings are available inthe MultiPoint Parameters menu in the terminal interface.3.6.1. 1 PPS Enable Delay1 PPS Enable DelaySetting DescriptionDefault Setting 255Options 255 to disable 1 PPS0 to 254 to enter the delaySetup TerminalMenu(5) Edit MultiPoint Parameters > (9) 1 PPS Enable/DelayDescription The 1 PPS Enable/Delay setting allows the radio network to propagate a 1PPSsignal from the Master to all Slaves in a MultiPoint network.When this parameter is enabled a properly generated pulse applied on the DTRline of the Master provides a 1 PPS pulse on the CD line of any Slave in thenetworkSetup 1PPS Enable/Delay1. Set the 1 PPS Enable/Delay parameter to 0in the Master.The Master must have a 1 PPS pulse on the DTR pin.2. Enable the 1 PPS Enable/Delay parameter on the Slaves.Slaves are calibrated at the factory.

Trigger an oscilloscope on the 1 PPS pulse on the DTR line of the Master.2. Monitor the CD line of the Slave.3. If the timing on the Slave differs from the Master it may be adjusted via the value in theSlave's 1 PPS Enable/Delay parameter. The difference in time between each incrementalinteger value is 542.534 nS. Changing the parameter to higher values decreases the Slavetime delay and changing the parameter to lower values increases the time delay.When properly calibrated the CD line of a Slave radio outputs a pulse that goes high for about 2ms in synch with the 1 PPS pulse on the Master radio. The output on the Slave occurs within 20microseconds of the input to the Master.Important!: When 1 PPS Enable/Delay is enabled, the Master must have a 1 PPS pulse on itsDTR pin, otherwise the RF network does not function.3.6.2.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Master Packet RepeatSetting DescriptionDescription In a Point-to-MultiPoint network, Slaves do not acknowledge transmissions fromthe Master. If Slaves did acknowledge all data transmissions, in a large network,the Master would soon become overwhelmed with acknowledgments from theSlaves. Without acknowledgments, 100% confidence every Slave has receivedevery packet cannot be met.To address this issue, you can modify the Master Packet Repeat parameter,assigning a value between 0(the packet is transmitted once) to 9(the packet istransmitted 10 times).FREEWAVE Recommends: Use a setting of 1or 2in a licensednetwork.For networks with solid RF links, this parameter should be set to a low value suchas 0or 1. If a network has some weak or marginal links it should be set withhigher values. If a Slave receives a good packet from a Master more than once itdiscards the repeated packets. Similarly, after a MultiPoint Repeater receives agood packet from the Master, it discards any further repeated packets. In turn, theRepeater sends the packet out to Slaves the number of times corresponding to itsown Master Packet Repeat setting.Increasing the Master Packet Repeat setting increases the probability of apacket getting through, but also increases latency in the network because eachpacket from the Master or Repeater is being sent multiple times. Therefore, it isimportant to find the optimal mix between network robustness, throughput, andlatency. In general, a setting of 0to 1works well for most well designednetworks.The Master Packet Repeat may be set to 0if the user software is capable of, orrequires acknowledgment. In this case, if the Master sends a packet that theSlave does not receive, the user software controls the retries as needed.3.6.6.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.3.6.11. RepeatersImportant!: Adding a Repeater to a network reduces the throughput by 50%. For example, over-the-air throughput in a network running at 2-Level GFSK and with the Repeaters parameter disabled is9600 bps. With the Repeaters parameter enabled, the over-the-air throughput drops to 4800 bps.The LRS455-C-U, -T-U, CE-U, TE-U radios are narrowband radios and have a limited channel sizebased on the license obtained from the FCC. Therefore, the radios can experience a dramatic impactin throughput if a Repeater is implemented in the network. If you have large amounts of data totransfer and choose to add a Repeater in your network, you must optimize polling host / RTUsettings to accommodate for the lower throughput. Polling host / RTU optimization settings includereducing block/packet sizes and increasing overall time-out parameters.Important!: This parameter needs to be set in the MultiPoint Master only. The setting has no effect ifset on a Slave.RepeatersSetting DescriptionDefault Setting (1) EnabledOptions l(0) Disabled - There is not a Repeater in the network.l(1) Enabled -There is a Repeater in the network.Setup Terminal Menu (5) Edit MultiPoint Parameters > (0) Number RepeatersDescription Indicates if there is a Repeater in the network.3.6.12.

This document cannot be reproduced in whole or in part by any means without written permission fromFreeWave Technologies, Inc.Retry OddsSetting DescriptionDescription While packets transmitted from the Master to the Slaves in a MultiPoint networkare not acknowledged, packets transmitted from Slaves to the Master are. It ispossible, that more than one Slave attempts to transmit to the Master at the sametime. Therefore, it is important that a protocol exists to resolve contention for theMaster between Slaves. This is addressed through the Max Slave Retry andRetry Odds parameters.After the Slave has unsuccessfully attempted to transmit the packet the numberof times specified in the Max Slave Retry parameter, it attempts to transmit tothe Master on a random basis. The Retry Odds parameter determines theprobability that the Slave attempts to retransmit the packet to the Master; a lowsetting assigns low odds to the Slave attempting to transmit. Conversely, a highsetting assigns higher odds.An example of how this parameter might be used would be when considering twodifferent Slaves in a MultiPoint network, one with a strong RF link and the otherwith a weak RF link to the Master. If a Slave has a week or poor link, set RetryOdds to 0, as it may become a "chatty" Slave and lockup your network, causing aloss of communication.When Retry Odds is set to 0, after the Slave has exhausted the number of retriesset in the Max Slave Retry parameter and still not gained the Master’s attention,the Slave’s data buffer is purged. A Retry Odds set to 0is recommended formost networks.3.6.13. Slave/RepeaterSlave/RepeaterSetting DescriptionDefault Setting (0) DisabledOptions (0) Disabled, (1) EnabledSetup TerminalMenu(5) MultiPoint Parameters > (A) Slave/RepeaterDescription The Slave/Repeater mode allows a radio in a MultiPoint network to switchbetween Slave and Repeater functions. When in this mode, a radio repeats anypackets sent across the network as well as uses the data port. Thus, where oneRepeater and one Slave may be required in another vendor’s network, FreeWavenetworks require only one radio.To operate a radio as a MultiPoint Slave/Repeater, the Modem Mode in theOperation Mode tab must be set to Point to MultiPoint Repeater and theSlave/Repeater parameter enabled.

The actualcurrent draw depends on many factors. The table below gives only a qualitativeindication of supply current savings. A low number reduces latency and a highnumber reduces current consumption.Setting Description0 Low power, disabled1 LEDs dimmed, radio remains awake, radio islistening to the Master’s transmissions on everyslot, and radio’s data port is shut down if theRTS line is de-asserted (low).In this case, the radio needs to be awakenedbefore it is able to send data to the Master.2 LEDs dimmed, radio sleeps every other slot.3 LEDs dimmed, radio sleeps 2 of 3 slots.4-31 LEDs dimmed, radio sleeps the number of slotscorresponding to the setting.Example: With a setting of 31 the radiosleeps 30 of 31 slots.NoteslPower savings occur only when the Slave is linked. No power savings occurwhen the Slave is transmitting data. Low Power Mode is of little value when aSlave has a constant, high throughput.lMCU Speed must be set to 0and RF Data Rate must be set to 3for LowPower Mode to operate properly.lTo communicate to an RS232 port of a radio that is in Low Power Mode, theRTS line must be held high to wake it up. The radio wakes up withinapproximately 20 milliseconds of when RTS goes high.

Using the Call Book in Point-to-Point NetworksThe Call Book is required in Point-to-Point networks. While the Call Book is an option in Point-to-MultiPoint networks, FreeWave strongly recommends using the Network ID feature in mostapplications. If a large MultiPoint network is implemented using the Call Book and you want to adda radio to the network, or need to replace a radio, you must physically travel to all radios in thenetwork and enter the new serial number in the radio's Call Book.Using the Call Book offers both security and flexibility in determining how FreeWave radioscommunicate with each other.You must set the following for two FreeWave radios to communicate in Point-to-Point mode:1. The Master’s serial number must be listed in the Slave's Call Book or Slave Security isturned off in the Slave .2. The Slave’s serial number must be listed in the Master's Call Book.3. The Master must be programmed to call the Slave.The Call Book allows you to incorporate up to 10 FreeWave radios, designate one Repeater, anddesignate which Slave the Master calls. To set the Entry to Call option, select the number in theEntry to Call field, select All to direct the Master to call all Slaves.Note: To set the Entry to Call option in the terminal interface, enter C at the Call Book menu,followed by the menu number corresponding to that Slave. To call any available Slave in the list,enter C then enter A to direct the Master to Call All.It is important that the Call Book slots (0-9) are filled sequentially starting with slot 0. When aMaster is instructed to Call All, it calls all Slaves listed until it reaches the first serial number of 000-0000 (or a blank slot). If a serial number is entered after the all zero number or as a Repeater, theMaster does not recognize it as a valid number.Note: When entering numbers into the Call Book, you need only define the Repeater in the Master'sCall Book. The Slave Call Book only requires the Master’s serial number. A Repeater need not haveanything listed in its Call Book.4.4. Set Call Book in Tool Suite1.

Operational RS422 and RS485 InformationFor RS422 and RS485, the FreeWave radio can drive 32 standard unit loads and loads the buswith only 1/8 unit load. This allows a maximum of 256 devices on the bus if all of the line receivershave 1/8 unit load.RS422 is used for 4-wire or full duplex communication with one Master and multiple Slave radios.lThe Master radio keeps the line driver asserted at all times.lThe maximum line length is 4,000 feet using two, 120 ohm twisted pair cables with a fifthwire for data common.lRS485 full duplex using 4-wire plus common is the same as RS422, except the system canhave multiple Masters on the bus.The most common operation of RS485 is a two-wire comprised of a 120 ohm impedance singletwisted pair.In this system the loading of the FreeWave radio is as described above, which allows up to 256 1/8unit load units on the bus.Maximum line length is also 4,000 feet with a third wire required for data common.The FreeWave radio checks the line to be certain no other device is transmitting before enablingthe line driver for data transmission.LUM0016AB Rev May-2018 Page 74 of 90 Copyright © 2018FreeWaveThis document is the property of FreeWave Technologies, Inc. and contains proprietary information owned byFreeWave.

Set Master Packet Repeat to 3in the radios that use RS485.3. Set Turn Off Delay to 4.The Turn Off Delay setting in the menu is used to control the length of time the transmitter driverstays asserted after data transmission has finished.lThis is needed to allow the last transmitted character to reach the end of a long line and isnormally set to one character length of time.lThis setting also allows three complete reflections to the end of the line to ensure the ringingon the line has fully dampened before releasing the bus to another device.FREEWAVE Recommends: Shorter line lengths may use shorter delays, but four one-quarter-character delay times are recommended.Note: In Modbus, a Turn Off Delay setting of 0causes internal timing errors.Important!: There is no provision for hand shaking in any of the above modes of operation.Data rates above 9600 bps in RF Data Rate = 5 and above 19200 bps in RF Date Rate = 4 are NOTrecommended without a protocol that can handle error detection properly.7.1.1.
