LUMOO16AB Rev D Transmission Characteristics 3 Edit Transmission Characteristics gt 3 Xmit Rate Both 1 Normal Any number between 0 to 9 FreeWave transceivers use a Master Transmit Beacon to provide low current consumption in the Slave transceivers The Slaves turn their receiver off when no data is being passed This setting allows the duty cycle of the Master Transmit Beacon to be changed A setting of 0 is the highest duty cycle and 9 is the lowest duty cycle If you are not polling for data that frequently or you are not installing new devices often you might want to lower your duty cycle and therefore would set this field to 9 Baud Rate 1 Edit Baud Rate gt Turn Off Delay Both 0 Any number between 0 and 9 Specifies the time after the end of transmission of a character to the RS485 bus that the transceiver stops driving the bus and releases the bus to other devices The units are of a character with a range of 0 to 9 An entry of 4 means a delay equivalent to the duration of a full character The default is zero delay 46 Turn On Delay Tool Suite Tab Setup Terminal Menu Network Type Default Setting Options Description Tx Frequency LRS455 Wireless Data Transceiver For data rates of 1200 bits S or slower avoid setting the Turn Off Delay parameter higher than 4 At those rates the functionality of the microprocessor changes so that a Turn Off Delay of 5 has the same effect as i

77. twork 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 Size of the blocks of data The longer the data blocks the fewer number of deployed Slaves can exist in the network LUMOO16AB Rev D 2 LRS455 Wireless Data Transceiver 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 Use of Repeaters Using the Repeater setting in a MultiPoint network decreases overall network capacity by 50 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 then fewer Slaves can link to the Master while receiving the same network performance When larger amounts of data are sent more frequently the overall network bandwidth is closer to capacity with fewer Slaves For examples and additional information about data communication links see the Examples of Data Communication Links section later in this document Point to MultiPoint Network Quick St
