MultipointNetwork
System designers using the XE900SL10 can create a point-to-multipoint network with up to 125 remote nodes. The
master node is assigned address 1. The remote nodes are assigned address from 2 to 126. Xecom created Count-Off
to insure efficient network operation. Count-Off allows the master node to poll the entire network in less than 10
seconds. The Count-Off creates a temporary time division multiplexing scheme which permits each node to report its
status without the handshaking sequence normally required for a wireless data exchange.
The Count-Off sequence is initiated by the AT#C command from the host system. The Master node broadcasts the
Count-Off command to all network nodes. Upon receipt of the Count-Off broadcast each remote node initializes an
internal timer. Then in sequence by address each node sends an 8-byte status message to the Master. The status
message is programmed with theAT#E: orAT#E= command. Due to difficulties in synchronizing the spread spectrum
signals, a node may sometimes miss the Count-Off command. The network administrator should poll any node that
does not respond to the Count-Off request to insure the network integrity
Using Count-Off network reporting will be completed in less than 10 seconds. Based on the status information the host
can then elect to service any of the remote nodes.
