3. 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 from the Slave to the Master In a MultiPoint network you determine the number of times outbound packets from the Master or LUMOO34AA Rev D 2 GX Serial Wireless Data Transceivers Repeater to Slaves or other Repeaters are sent The receiving transceiver Slave or Repeater accepts the 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 Re
