4. e Tool Suite Tool Suite is the newest configuration software and replaces EZConfig and is the recommended method for programming your transceivers It provides a group of tools for configuring the devices in your network and for monitoring your network s performance Using the Configuration application within Tool Suite you can program changes to your transceiver s settings Tool Suite is available on the User Manual and System Tools CD and is also available for download from www freewave com For more information about using Tool Suite see the Too Suite User Manual available on the User Manual and System Tools CD or by selecting File gt Help in the Tool Suite software e Terminal Emulator A terminal emulator program such as HyperTerminal or Tera Term offers many of the same configuration options that are available in the Configuration application in Tool Suite Terminal emulators vary in cost and several are downloadable free of charge If you run versions of the Windows operating system prior to Windows 7 HyperTerminal is included in the operating system installation However if you are run Windows 7 or newer HyperTerminal is no longer available You can use the terminal emulator program of your choice to program the transceiver The Setup Terminal application within Tool Suite provides the same interface that is available using a terminal emulator You can also still use EZConfig to program your older transceiver models how

GXM Wireless Data Transceivers first packet received that passes the 32 bit CRC However the packet is not acknowledged On the return trip to the Master all packets sent are acknowledged or retransmitted until they are acknowledged Therefore the return link in a MultiPoint network is generally very robust Traditionally a MultiPoint network is used in applications where data is collected from many instruments and reported back to one central site The architecture of such a network is different from Point to Point applications The following parameters influence the number of transceivers that can exist in a MultiPoint network 1 Data block size The longer the data blocks the fewer number of deployed Slaves can exist in the network 2 Baud rate The data rate between the transceiver and the device to which it is connected could limit the amount of data and the number of transceivers that can exist in a network 3 The amount of contention between Slaves Polled Slaves vs timed Slaves 4 Repeater Use Using the Repeater setting in a Point to Point or MultiPoint network decreases overall network capacity by 5096 For example if the network polls Slaves once a day to retrieve sparse data several hundred Slaves could be configured to a single Master However if each Slave transmits larger amounts of data or data more frequently fewer Slaves can link to the Master while receiving the same network performance When larger amounts of d
