Overview Preliminary 61. OverviewThis document contains information about the hardware and software interface between anAeroComm PKLR2400 Radio and an OEM host. Information includes the theory of operation, systemissues, and a basic command set for operational control of the system and radio.The Radio is designed to allow flexibility at the hardware interface level with a minimum numberof actual hardware pins connecting the radio and the OEM Product. The radio is controlled by a Dallas87C520 microcontroller providing program storage. A separate EEPROM provides user definableparameter storage.The RF system is a Client/Server (Slave/Master) architecture. Data can be transmitted from clientto server or server to client, but not from client to client, or server to server. Clients can only hear serversand servers can only hear clients.The Serial Interface Modes provide four main serial user interfaces. This protocol providessignificant flexibility to the OEM allowing them to provide data in many forms including packet, endcharacter and fixed-length with and without timeouts.

PKLR2400 Specifications Preliminary 83. Theory of Operation3.1 DefinitionsServer Host: The server host is the OEM device controlling the server radioClient Host: The client host is the OEM device controlling the client radioHost: Host refers to both the server host and the client hostServer Radio: The server radio is the “master” radio. It is the hub of communicationsClient Radio: The client radio is a “slave” radio. It is controlled by it’s own Host, but is a slave to theserver radioAuthentication: The acquisition of the IEEE 802.3 address of the Server Radio by the Client Radio and thesubsequent issuance of an In-Range* command by the Client Radio to the Client Host.Unicast Address: A frame that is directed to a single recipient as specified in IEEE 802.3.Broadcast Address: A frame that is directed to multiple recipients as specified in IEEE 802.3.3.2 Serial Interface ModesThe PKLR2400 provides four Serial Interface Modes with programmability within each modeallowing maximum system flexibility. These four Serial Interface Modes include three transparent modesand one API mode. The radio-to-radio protocol is identical on all three Transparent Serial Interface Modes.This allows all three Transparent Serial Interface Modes to coexist within the same network. The APISerial Interface Mode 03 is not interoperable with the Transparent Serial Interface Modes 01, 02 and 04.3.2.1 Serial Interface Mode 01 – Transparent, Fixed Length, with TimeoutMode 01 specifies Transparent mode with fixed length packets and active timeout. Packets will betransmitted over the RF interface when one of the following conditions occurs:• The number of data bytes received over the interface is equal to the buffer specified bythe user in EEPROM address locations 43H and 44H.• A byte gap larger the timeout specified by the user in EEPROM location 4DH occurs.3.2.2 Serial Interface Mode 02 – Transparent, End CharacterMode 02 specifies Transparent mode with End Character. Packets will be transmitted over the RFinterface when the user-defined End Character is received by the radio over the interface. The EndCharacter is defined by the user at EEPROM location 3EH.
Theory of Operation Preliminary 93.2.3 Serial Interface Mode 03 – APIMode 03 specifies API Mode. In this mode, the OEM has control of the radio command setdetailed in Section 6.2. Packets are transmitted upon completion of the Send_Data command.In API Serial Interface Mode 03, the OEM host may utilize a set of basic commands to control theradio and system. These commands allow the customer to establish system parameters through theprogramming of variables in EEPROM as well as monitoring system performance. These commands canonly be exercised when the radio is in API Serial Interface Mode 03. It is important to understand twoaspects of the software commands.1. There are only three commands that are issued from the client radio to the Client Host. Thesethree commands are Out_of_range*, In_range* and Receive_data*. The Receive_data*command is the only command issued from the Server radio to the Server Host. It isimportant to note that these commands will NOT get an acknowledgement, they are signals tothe Host to alert it to incoming data, or a change of status.2. All remaining commands initiated by the Host MUST receive an acknowledge from the radioto signal completion of the assigned task. This works as flow control for the informationgoing to the radio.The server radio can receive data from a total of 75 different clients, but from only 8 differentclients in any 30 millisecond interval. It is possible that there will be multiple Receive_data* commands atthe same time. Since there is no reply command at the completion of Receive_data*, the Host must becapable of handling up to 8 Receive_data* commands at one time.Note: This means that whenever a command is initiated by the radio to the Host, the Host must beready to accept the command and any data following the command.Note: A full list of commands, definitions, and implementation can be found in Section 6.3.2.4 Serial Interface Mode 04 – Transparent, Fixed Length, No TimeoutMode 04 specifies Transparent mode with fixed length packets and no timeout. Packets will betransmitted over the RF interface when the number of data bytes received over the interface is equal to thebuffer specified by the user in EEPROM address locations 43H and 44H.3.2.5 Serial Interface BufferThe serial interface buffer provides 8Kbytes of memory broken into four dynamic regions. In theAPI Serial Interface Mode 03, only one region is utilized. In the Transparent Serial Interface Modes 01, 02and 04, a buffer region is used each time a packet release condition is met. As an example, in EndCharacter Mode 02, if 500 bytes are transmitted followed by the specified end character, 500 bytes will bestored in the first region and the remianing 7.5Kbytes will be dynamically allocated for the next threepackets. It is strongly recommended that CTS or upper layer protocol with acknowledgements be used bythe OEM when operating in Transparent Serial Interface Control Modes to eliminate the following systemissues:Note: If all four buffers are filled and the OEM host continues to send data over the interface, it willbe discarded by the radio. This can be eliminated if the OEM utilizes CTS.
Theory of Operation Preliminary 103.3 Initialization SequenceWhen operating in the three Transparent Serial Interface Modes, the initilization sequence ismanaged by the AeroComm protocol. In-Range commands are not issued and there is no acknowledge fromthe radio on data delivery unless the OEM protocol has built-in acknowledgement.When operating in the API Serial Interface Mode 03, the following initialization sequenceoccurs. During the power up sequence or upon a Reset* command, the Clear to Send (CTS) line is set high(5V TTL logic levels). While CTS is high, initialization occurs, and when finished, CTS is put lowindicating successful initialization is complete.Note: At this point, the only command that can not be issued is the Send_data* command. Thiscommand can only be issued after the RF_enable* and In_range* commands have been issued.Before data communications can begin, a client radio needs to be authenticated. The client hostmust issue an RF_enable* command to activate the client radio and receive an acknowledgement from theclient radio. The server radio transmits a beacon containing it’s IEEE 802.3 address. Once the client radiohas been activated by use of the RF_enable* command, it will receive the server radio IEEE 802.3 addressonce it is in range. Upon receiving the IEEE 802.3 server radio address, the client radio will issue anIn_range* command to the Client Host containing the IEEE 802.3 server radio address.The client host must receive the In_range* command from the client radio before the Send_data*command is invoked. Broadcast mode, as defined by IEEE 802.3, is supported and can be used to senddata to all radios that are within range but its use should be limited because reception of the message is notguaranteed.When the last bit of data is transferred from the Host to the radio, the Host must wait for the CTSline to transition high (meaning that the radio has found the end of the data packet) and then transition backlow (meaning that the radio is ready for the next command).Clear To Send minimum delay of 40µµµµs between (1) and (2) after end of data packetNote: All serial data must be transmitted LSB first.Note: These radios are designed to be single threaded, meaning that for every command issued, thereis a reply command that signifies the completion of the command issued. There can be nointerleaving of commands.CTSfromRadioDelay for reply command*Note: If level translators areused the CTS signal will beinverted coming from the radio.TXDLSB FirstFrom Host Command Length ChecksumData(1) (2)

Developers Kit Preliminary 134.3 Pin Descriptions for Connector J1Special considerations for the hardware interface at connector, J1, are described in this section.All remaining pin descriptions are standard for serial hardware interfaces.4.3.1 No ConnectAll No Connect pins 2, 4, 6-19, 22, 28-35 and 37 must not be connected to logic high or lowlevels, but must be left floating.4.3.2 VccAll Vcc pins 3, 5 and 39 require power of 5Vdc + 5% with ripple of less than 50mv p-p.4.3.3 Clear To Send (CTS)Clear To Send (CTS), pin 23, requires a minimum delay of 40µs between (1) and (2) after end ofeach data packet.Figure 1. Timing Note for CTS Pin4.3.4 ReservedThe reserved pins 24 and 25 are used by AeroComm for internal testing and/or future radioenhancements. These pins should be treated as No Connect pins and must not be connected to logic high orlow levels, but must be left floating.4.3.5 Baud Rate Selector (BDSEL)The Baud Rate Selector (BDSEL), pin 26, provides the user a default method of communicatingwith the radio in the event the EEPROM baud rate parameters become corrupted. If pin 26 is logic highlevel or not connected, the baud rate will default to the variables specified in EEPROM. If pin 26 is logiclow level, the baud rate will default to 9600 baud.4.3.6 Forced API Mode 03 (PKTMODE)Forced API Mode 03 (PKTMODE), pin 27, provides the user a method of programming the radiofrom any of the Transparent Serial Interface Modes to the API Serial Interface Mode.

Developers Kit Preliminary 14the radio be in API Serial Interface Mode to execute the Command Set or to configure any of theEEPROM parameters. To force the radio into API Serial Interface Mode 03, pin 27 must be held at logiclow level and the radio reset. The radio can not be placed into any of the Transparent Serial InterfaceModes 01, 02 or 04 until pin 27 is held at logic high level and reset.4.3.7 Microprocessor Reset (uP RESET)Microprocessor Reset (uP RESET) is achieved by holding pin 38 at logic high level for aminimum of 2ms. If uP RESET is performed after power has been applied to the radio and is stable, thereset time will be significantly less. At all other times, pin 38 should be logic low level. If pin 38 is notconnected, the microprocessor will hold pin 38 at logic low level.4.3.8 EEPROM Write Protect (E2WP)EEPROM Write Protect (EEWP) is enabled when pin 37 is at logic high level or left floating. Pin37 must be logic low level to Write to the EEPROM.

Developers Kit Preliminary 17J3-J9 Level Translator SettingsIf a PC will be used as the OEM server or client host, then level conversion must be enabled toconvert from the RS-232 levels at the PC to the 5 Volt TTL logic levels used on the radio. To enable levelconversion, place jumpers J3-J9 on pins 2 and 3, see Figure 3. If another device (0-5 volt TTL logic levels)is to act as the Host for the radio then the user must disable level conversion. To disable level conversion,place jumpers J3-J9 on pins 1 and 2 see figure 4. If running under Windows, jumper J6(PKTMODE/RTS) must be removed.Figure 3. Level Translation Enabled Figure 4.

Developers Kit Preliminary 18The developer kit includes a 3.5” diskette of software utilities allowing the customer to exercisethe radios upon receipt. The software utilities are written for a DOS environment. The softwareutilities will not operate properly under a DOS shell in Windows or Windows. The software includesseveral files as follows:• OEM.EXE – Interactive Command/EE Edit Software/Transmit Receive Emulator.• *.RTC – Script files that automate radio mode setup and demonstrates operation.• PORTS.CFG – Com port address and baud rate information• README.TXT – Further utility software documentation and latest release notes• OEM.CFG – Configuration file for OEM.EXE• OEMRWSP.INI – AeroComm Use OnlyThese files are located in each of three directories as follows:1. OnePC – This directory contains all the files required to run the Client and Server radios on a singlePC. The Client Radio must be connected to Com1 (3F8) and the Server Radio must be connected toCom 2 (2F8)2. ClientPC- This directory contains the Client Radio files that are required to run the Client Radio onone PC and the Server Radio on a separate PC. The Client Radio should be connected to Com 1 (3F8)3. ServerPC- This directory contains Server Radio files that are required to run the Client Radio on onePC and the Server Radio on a separate PC. The Server Radio should be connected to Com 1 (3F8)5.2.1 OEM.EXEThis software contains three unique utilities to exercise, monitor and setup modes in the radios.These utilities are: Transmit/Receive Emulator, Single Line Command Interface, and EEPROMViewer/Editor.5.2.1.1 Transmit/Receive EmulatorThis software allows (1) Server and (1) Client radio to communicate with each other. Thesoftware comes pre-configured for the two radios in the development kit.When connecting the Client and Server Radios to the same PC, connect the Server Radio toCom 2 (2F8), then connect the Client Radio to Com 1 (3F8). Copy the OnePC directory and contents to thePC.When connecting the Client and Server Radios to separate PCs, connect the Server Radio toCom 1 (3F8) on one PC, then connect the Client Radio to Com 1 (3F8) on a separate PC. Copy theClientPC directory and contents to the PC with the Client Radio attached. Copy the ServerPC directory andcontents to the PC with the Server Radio attached.Note: The factory default for the Client Radio and Server Radio is API Serial Interface Mode 03.Run OEM.EXE on one or both PCs as dictated by your setup. Press the 'F3' key to perform aRESET and RF_Enable on all PCs. Press the 'F9' key to run the script files and demonstrate continuousdata transfers between radios. Press the 'Esc' key to stop. Pressing the 'Esc' key again will exit from theprogram.Note: The “F3” key should be used only when the radios are in API Serial Mode 03. Use “Alt R” toperform a RESET of the radios in Transparent Serial Modes 01, 02 and 04.While running, the screen will display transmit timeouts, receive timeouts, and run number. TheEmulator program is controlled by script files. The script files can be edited by the user and detailed
Developers Kit Preliminary 19instructions on how to write a script file can be found in the section below describing *.RTC. While in theEmulator, pressing the ‘Alt’ key will bring up a window with 7 choices: File, Settings, Window, Reset,Enable, Help and About. The File option allows the user to load a script file or execute a mode setup scriptto ports 1 or 2. The Settings option allows the user to change baud rate and other settings. The Windowoption allows the user to view the trace buffer or a list of the script commands. The Reset command issues aReset command to all ports configured in PORTS.CFG. The Enable command sends a RF_Enable to allports configured in PORTS.CFG.Note: The factory default for the Client Radio and Server Radio is API Serial Interface Mode 03.Therefore, both radios must receive an RF_enable before scripts can be run.Note: Receive commands expecting more than 16 bytes will fail in 'F10' single-step mode.The Transmit/Receive Emulator can also be used to execute the setup scripts provided with theprogram. For a full list of the scripts, see the readme.txt file in the directory labeled ‘Scripts’ on the disk.To execute a script, press ‘alt-F’ and then ‘Enter’ to bring up a selection window. You can enter the nameof the setup script to be run, or hit ‘Enter’ to see a list of all the available script files. It is important to notethat when you hit ‘Enter’ it will show all the script files that are in the same directory as the executableoem.exe. Once you have a script file loaded, then you will need to depress the write protect tab on theserial adapter board while you single step (‘F10’) through the commands in the script.

Developers Kit Preliminary 20*.RTC files contain all of the configuration information for OEM.EXE. *.RTC files can bemodified to change timeouts, ports, and commands. *.RTC files require very specific format as detailedbelow:* -- begins and ends each command sequenceT -- invoke transmit sequence over serial host/radio interface (API Mode 3)R -- invoke receive sequence over serial host/radio interface (API Mode 3)C -- invoke transmit sequence over serial host/radio interface (Transparent Modes 1,2,4)S -- invoke receive sequence over serial host/radio interface (Transparent Modes 1,2,4)D -- invoke delay Note: Any line beginning with a "space" character is interpreted as a comment Note: The first line in PING.RTC is always interpreted as a commentExample Command Format*T[transmit port number] [timeout][transmit port number] is either "1" or "2" as designated in PORTS.CFG[timeout] is between "0000" and "9999" and is measured in milliseconds[Command] [Length Low] [Length High] [Data] [Checksum automatically provided]*5.2.3 PORTS.CFGBefore attempting to run the executables, the user must ensure the development kit radios areattached to the two ports specified in PORTS.CFG. The default configuration for PORTS.CFG assumesthat both developer kit radios are connected to the same computer.The default baud rate in PORTS.CFG is 57600. This should not be changed unless theEEPROM has been corrupted. In the event of corrupted EEPROM, hit “AltS” in the OEM.EXE programto change the baud rate to 9600 and pin 26 on the interface connector, J1, of the radio must be logic lowlevel to communicate.Note: If the EEPROM parameters for baud rate are changed, and the radio is reset, these utilitieswill not communicate with the radio until pin 26 is held at logic low level and the third line ofPORTS.CFG is changed to 9600.5.2.4 Setup ScriptsAeroComm provides several scripts to allow easy setup and configuration for different modes. These setupscripts are as follows:S1AC.RTC – Setup client radio to Mode 1 AddressedS1AS.RTC – Setup server radio to Mode 1 AddressedS1NC.RTC– Setup client radio to Mode 1 Non-AddressedS1NS.RTC– Setup server radio to Mode 1 Non-AddressedS2AC.RTC– Setup client radio to Mode 2 AddressedS2AS.RTC– Setup server radio to Mode 2 AddressedS2NC.RTC– Setup client radio to Mode 2 Non-AddressedS2NS.RTC– Setup server radio to Mode 2 Non-AddressedS4AC.RTC– Setup client radio to Mode 4 AddressedS4AS.RTC– Setup server radio to Mode 4 AddressedS4NC.RTC– Setup client radio to Mode 4 Non-Addressed

Configuring the PKLR2400 Preliminary 317. Configuring the PKLR2400 RadioThe various configurable parameters are stored in the EEPROM in the Radio. These parametersare read by the AeroComm firmware on power-up reset. These parameters can be configured byAeroComm as AeroComm defaults or customer defaults. These parameters can also be configured by thecustomer using a PC and an AeroComm provided adapter. If the customer is writing to the EEPROM, theymust use the Write EEPROM Command and enable E2WP, pin 37, or switch 2 on the serial adapter boardincluded with the developer kit. The different configurable parameters and their respective EEPROMlocations are highlighted in this chapter.7.1 System EEPROM ParametersThe system EEPROM parameters provide general system configuration information for the radio.These parameters can be monitored and changed independent of the serial interface protocol. Theseparameters can only be changed when the API Serial Interface Mode 03, described in Section 7.1, isactive.EEPROMAddress Size Description0H 40 bytes Product identifier string/Version Info28H 6 bytes IEEE assigned MAC Address2EH 1 byte Channel number; Range = 01- 75; Default = 00;33H 1 byte Client/Server mode01 – Server Radio mode02 – Client Radio mode (default)34H 8 bytes System ID - used to demarcate RF networks (default=00 00 00 00 0000 00 01)40H 1 byte Baud High (BH) – Default is FF41H 1 byte Baud Low (BL) – Default is F77.1.1 Product Identifier String/Version InformationEEPROM Address: 0HSize: 40 bytesUseful for OEM to read AeroComm version information.

Thisallows for up-to 75 independent, co-located data networks. Default shipped at 00. It is highlyrecommended that this be changed to a channel number other than 00.Note: Channel Number AND System ID between clients and server must be identical for radios tocommunicate.7.1.4 Client/Server ModeEEPROM Address: 33HSize: 1 byteDefault: 02Range: 01-02Specifies whether the radio is operating in the Client Mode (02) or Server Mode (01)7.1.5 System IDEEPROM Address: 31HSize: 8 bytesDefault: 00 00 00 00 00 00 00 01Range: 00 00 00 00 00 00 00 00 to FF FF FF FF FF FF FF FFNote: Channel Number AND System ID between clients and server must be identical for radios tocommunicate.

Configuring the PKLR2400 Preliminary 347.2 Protocol EEPROM ParametersThe protocol EEPROM parameters are related to the Serial Mode interface selection. A summaryof the required EEPROM settings is illustrated in Section 7.3.Note: These parameters can only be changed when the API Serial Interface Mode 03 is active.When in Transparent Serial Interface Modes, this can be accomplished by holding pin 27,PKTMODE, low and resetting.Note: When writing to EEPROM using the developer kit, remember to hold the EEPROM writeprotect switch during the write command.EEPROMAddress Size Description2FH 1 byte Transmit data link attempts; Range = 01 - FF;Default = 10H;31H 1 byte Receive mode - determines what type of data frames are received by theOEM Product, based on MAC address of received frame01 - unicast/broadcast data (default)02 - unicast only03 - all (promiscuous mode)32H 1 byte In-Range, Out-of-Range Refresh.

Configuring the PKLR2400 Preliminary 357.2.1 Transmit Data Link AttemptsEEPROM Address: 2FHSize: 1 byteDefault: 10HRange: 01-FFThis parameter specifies the maximum number of attempts over the RF interface. Serial Interfacemode 03 will respond with a Send Data Failure when maximum Data Link attempts is achieved. All othermodes will not receive an acknowledge.Note: Transmit Data Link Attempts must be set to 01 when operating in the Broadcast Mode of theAddress Transparent Control.7.2.2 Receive modeEEPROM Address: 31HSize: 1 byteDefault: 01Range: 01-03This parameter applies only to API Serial Interface Mode 03. The default, 01, specifiesUnicast/Broadcast. Unicast will receive all packets that match the receiving unit IEEE assigned address.Broadcast is achieved by placing FF in all six bytes of the IEEE assigned destination address sent fromsender. In Broadcast mode, the receiver will accept all data with a destination address that has FF in all sixbytes. It is important to note that there is no RF acknowledge on Broadcast packets. Mode 01 willaccept Unicast and Broadcast data packets and discard all others. In Unicast only mode, 02, The receivingradio will receive only Unicast packets and discard all others. In Promiscuous mode, 03, the receiving radiowill accept all packets with the same System ID.Note: The Receive Mode must be set to 03 in all Transparent Serial Interface Modes including 01, 02and 04 at EEPROM location 4AH.7.2.3 In-Range, Out-of-Range RefreshEEPROM Address: 32HSize: 1 byteDefault: 14HRange: 01-FFThis parameter is used only when the radio is operating in API Serial Interface Mode 03. The In-Range, Out-of-Range Refresh parameter allows the user to select the interval between which the client radiosearches for Server beacon that includes the Server IEEE source address. This parameter is very usefulwhen operating in a fringe condition to minimize the In-Range and Out-of-Range commands that may floodthe host. AeroComm has established a default value of 5 seconds through extensive testing.
Configuring the PKLR2400 Preliminary 367.2.4 End Character DefinitionEEPROM Address: 3EHSize: 1 bytesDefault: 0DRange: 00-FFThis parameter is used only when the radio is operated in Serial Interface Mode 02 specified byEEPROM address 4AH. Otherwise, this parameter is ignored by the system. The parameter specified bythe user will indicate the last character in a data packet. When this end character is seen by the radio, thepacket will be transmitted. The packet length including the end character can not exceed 2Kbytes.7.2.5 Fixed Packet Length High Byte/Low ByteEEPROM Address: 43H/44HSize: 1 byte eachDefault: 01/00Range: 00/01 to 07/FFHThis parameter is active only when the radio is in Serial Interface Modes 01 or 04 specified byEEPROM address 4AH. This parameter is ignored in all other modes. The fixed packet length can notexceed 2Kbytes or it will not be received.7.2.6 Serial Interface ModesEEPROM Address: 4AHSize: 1 bytesDefault: 03Range: 01-04There are four Serial Interface Modes for the OEM radio including one packet mode and threetransparent modes. All modes are differentiated by the definition of when data will be transmitted by theradio.Mode 01 specifies Transparent mode with fixed length packets and active timeout. Packets will betransmitted over the RF interface when one of the following conditions occurs:• The number of data bytes received over the interface is equal to the buffer specified bythe user in EEPROM address locations 43H and 44H.• A byte gap larger the timeout specified by the user in EEPROM location 4DH occurs.Mode 02 specifies Transparent mode with End Character. Packets will be transmitted over the RFinterface when the user-defined End Character is received by the radio over the interface. The EndCharacter is defined by the user at EEPROM location 3EH.Mode 03 specifies API Mode. In this mode, the OEM has control of the radio command setdetailed in Section 6.2. Packets are buffered and transmitted at the direction of the OEM.
Configuring the PKLR2400 Preliminary 37Mode 04 specifies Transparent mode with fixed length packets and no timeout. Packets will betransmitted over the RF interface when the number of data bytes received over the interface is equal to thebuffer specified by the user in EEPROM address locations 43H and 44H.Note: EEPROM parameters can not be programmed once the radios are programmed and reset inany of the Transparent modes 01, 02 or 04. The radio must be programmed to API mode 03 to accessEEPROM parameters. This can only be accomplished by holding pin 27 low during and after reset.7.2.7 Destination Address ControlEEPROM Address: 4BHSize: 1 bytesDefault: 00Range: 00-01This parameter sets the destination address for Transparent Serial Interface modes only. TheAPI Serial Interface Mode 03 utilizes the Receive Mode at EEPROM address 31H to specify addressmodes. With Destination Address Control set at the default, 00, the radio will determine if the six byteIEEE address at 50H matches. If the destination address matches, the data packet is forwarded to the OEMhost. Otherwise the data is discarded. This addressed mode guarantees delivery of the data packet over theradio link by using aknowledgements.With Destination Address Control set to Broadcast Mode, 01, clients will receive all data packets.There are no acknowledgements and no data packet retries in this mode.Client radios can operate in Destination Address Control Mode 00, providing more reliabledelivery of data to the Server radio. At the same time, the Server radio can operate in DestinationControl Mode 01, acting as a broadcasting server without guaranteed delivery. This provides aunique method of implementing a data network of many-to-one or one-to-many.7.2.8 Interface Timeout ControlEEPROM Address: 4DHSize: 1 bytesDefault: 00HRange: 00, 40, 80 or C0The Timeout parameter applies only to the Transparent Serial Interface Mode 01 with fixed lengthpackets and timeout. This parameter specifies the amount of time between bytes that the radio will waitbefore transmitting the data packet.
Configuring the PKLR2400 Preliminary 387.2.9 Broadcast AttemptsEEPROM Address: 4EHSize: 1 bytesDefault: 04HRange: 01-FFThe Broadcast Attempt parameter applies only to the Broadcast modes for all four serial packetmodes and specifies the number of times that the RF will broadcast every packet. The receiving radio willdiscard duplicate packets.7.3 EEPROM Parameter SummaryEEPROM PARAMETERSBYSERIAL INTERFACE MODESAddress Description A B C D E F G H I4AH Serial Interface Mode 01 01 02 02 03 03 03 04 042FH Transmit Attempts 01-FF 01 01-FF 01 01-FF 01-FF 01-FF 01-FF 0131H Receive Mode 03 03 03 03 01 02 03 03 0332H Range Refresh NA NA NA NA 01-FF 01-FF NA NA NA3EH End Char Definition NA NA 00-FF 00-FF NA NA NA NA NA43H Fixed Pkt Length-HB 01-07 01-07 NA NA NA NA NA 01-07 01-0744H Fixed Pkt Length-LB 00-FF 00-FF NA NA NA NA NA 00-FF 00-FF4BHDest Address Control00010001NANANA00014DH Interface Timeout Table Table NA NA NA NA NA NA NAMode DefinitionsA.
