Number Repeaters (Menu Option 0)
In a Multipoint network it is critical for timing purposes to know whether or not there are
repeaters in the network. Any transceiver that is used as a repeater essentially becomes a
master to the slaves and other repeaters to which it is communicating. Therefore, the user
must identify whether or not the network contains repeaters. This is done by assigning a
value in parameter (0), Number Repeaters. The value should be 0 if there are no
repeaters in the network and 1 if repeaters are present. This parameter must be set to the
same value in all units in a Multipoint network (master, slaves, and repeater(s)).
Master Packet Repeat (Menu Option 1)
In point-to-point operation the transceivers acknowledge every data packet transmitted.
In a point-to-multipoint network, the slaves do not acknowledge transmissions from a
master to the slaves. This is to prevent system overload. If the slaves acknowledged all
data transmissions from the master in a large point-to-multipoint system, then all system
capacity would be spent having the master listen for acknowledgments from the slaves.
Because the transmission is not acknowledged by the slaves, 100% confidence does not
exist that every slave has received every message from the master. To address this issue
