Torealize full power savings in Low Power Mode the serial port must be deactivated between operation To do that the RTS line must be asserted However because RS485 422 operation uses the RTS line as part of the data 51 Chapter 3 Configuring Point to MultiPoint Networks bus it cannot be asserted to wake up the radio Therefore FreeWave recommends that all radios set to RS485 or RS422 use a Low Power Mode of 0 Reading Diagnostics in Tool Suite The Network Diagnostics application provides a place to view diagnostic data for all the devices connected to the Master in your network in real time This application is not meant to replicate the functionality of an NMS system but rather it is a tool that can be used for diagnostics and troubleshooting in the field Important The Network Diagnostics application is intended for occasional network monitoring or troubleshooting not for continuous long term collection of diagnostic data This section provides basic steps for reading diagnostics using Tool Suite Tool Suite stores the diagnostic data in the database and you can import or export a diagnostic file For information regarding the data available recommended best practices and importing and exporting files using the Network Diagnostics application see the Tool Suite User Manual available on the User Manual and System Tools CD or by selecting File Help in the Tool Suite software Note To help identify the transceivers in

4. To call a Slave through one or more Repeaters that Slave must be called individually With Call All selected the Master will not connect with any Slaves through Repeaters The Master calls every Slave in the list and connects with the first Slave that responds When calling through a Repeater the Master must first call that Repeater and establish a communication link with it prior to making contact with the Slave LUMOO14AB Rev C 60 Chapter 5 Advanced Programming The settings and scenarios covered in this chapter are considered advanced programming and are settings and scenarios that you are not as likely to use in your network Working with Parallel Repeaters As you add Repeaters to your network plan accordingly do avoid creating a parallel Repeater scenario A parallel Repeater is defined as two or more Repeaters linked to the same point in the network LUMOO14AB Rev C 61 Chapter 5 Advanced Programming The Slave in the middle has overlapping coverage from both the Repeaters parallel Repeaters Data from the Repeaters is transmitted on the same Freguency Key in the same time slot which creates message collisions To resolve this scenario change the following settings on one or more of the Repeaters in conflict e Repeater Frequency Set the Repeater Frequency parameter in the MultiPoint Parameters tab to any number other than 0 If set to a number other than 0 the transceiver uses the frequency key set in the Frequency

Chapter 2 Basic Transceiver Programming and Setup Transceivers that contain the same settings in all these parameters can communicate with each other If you choose to use the Call Book instead of the Network ID or are running a Point to Point network the appropriate serial numbers must be listed in the Call Book for each transceiver If you are working with parallel Repeaters the Frequency Key setting may differ Setting RF Transmission Characteristics The Transmission Characteristics parameters allow you to modify settings that determine how data is sent between transceivers in your network Many of these parameters must be maintained throughout the network for proper functionality Important The parameters in the Transmission Characteristics tab are only for the advanced user who has a good understanding of the principles of RF transmission Several settings on a Slave or Repeater transceiver come from the Master and are therefore set only at the Master Settings that you must set on each Slave or Repeater include the following e Transmit Power e Slave Security e Retry Time Out e Hop Table Size e Hop Table Version e Hop Table Offset You can leave most parameters in the Transmission Characteristics tab set to their default settings when completing basic setup However you must set the following parameters and they must be the same for all transceivers in your network e Frequency Key e Hop Table properties Size Versio
7. Description The Retry Time Out parameter in a Slave or Repeater sets the delay the unit waits before dropping the connection to a Master or Repeater The factory default is set at the maximum of 255 The maximum setting means that if 1 packet in 255 is sent successfully from the Master to the Slave or Repeater the link is maintained The minimum setting is 8 This allows a Slave or Repeater to drop a connection if less than 1 in 8 consecutive packets is successfully received from the Master The function in the Master is effectively the same With a setting of 255 the Master allows a Slave or Repeater to stay connected as long as 1 packet in 255 is successfully received at the Master The Retry Time Out parameter is useful when a MultiPoint network has a roving Master or Slave s As the link gets weaker a lower setting allows a poor link to break in search of a stronger one Note Setting Retry Time Outto 20 in the MultiPoint Master is recommended in areas where several FreeWave networks exist This recommended setting allows Slaves and Repeaters to drop the connection if the link becomes too weak while at the same time prevent errant disconnects due to interference from neighboring networks While intended primarily for MultiPoint networks the Retry Time Out parameter may also be modified in Point to Point networks However the value in Point to Point mode should not be set to less than 151 RF Data Rate Golden Setting Note In Mul

The value indicates the total number of disconnects that have occurred from the time the transceiver is powered on until the radio is put into Setup mode Under ideal operating conditions the number of disconnects should be 0 One or more disconnects may indicate a weak link the presence of severe interference problems or loss of power to any of the radios in the link Note In Tool Suite the disconnect information is available in the Summary View in the Network Diagnostics application Radio Temperature The Radio Temperature value is the current operating temperature of the transceiver in degrees Celsius For proper operation a FreeWave transceiver must be in the temperature range of 40 to Some of the transceivers are only tested to 0 C See the transceiver specifications later in this document for details Rate 96 The Rate measures the percentage of data packets that were successfully transmitted from the Master to the Slave on the first attempt A number of 75 or higher indicates a robust link that provides very good performance even at high data transmission rates A number of 15 or lower indicates a weak or marginal link that provides lower data throughput A Rate of 100 provides approximately 100 KBaud of bandwidth with an RF Data Rate setting of 3 and approximately 150 KBaud of bandwidth with an RF Data Rate of 2 These numbers are reduced approximately 5096 if one or more Repeaters are in the network LUMOO14AB Rev C 70
