Multipoint Network
System designers can create a point-to-multipoint network with up to 253 remote nodes. The master node
is assigned address 1. The remote nodes use addresses 2 to 254. For efficient network operation, Count-
Off™ allows the master node to poll the entire network in under 10 seconds.
Count-Off™ permits the master node in a point-to-multipoint system to quickly check the status of all
network nodes. It 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.
Count-Off™ is initiated by the AT#C command, from the host system. The master node broadcasts the
command to all network nodes. Upon receipt of the command each remote node initializes an internal
timer. Then in sequence by address each node transmits an 8-byte status message. The status message
is programmed with the AT#E: or AT#E= command. The status byte is passed to the host system in the
correct sequence upon receipt of the Count-Off message from the master node.
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.

microcontroller. Xecom has created a way for our customers to run their simple remote monitoring application
on the transceiver’s communications controller saving the complexity and cost of incorporating a separate
microcontroller.
Has shown in the software block diagram above, the User Code interfaces to the rest of the XE24S code
through the User Code Support block. The User Code Support block interfaces to the AT command engine
and serial interface and supports other features such as sub routine calls.
To prevent the User Code from interfering with the communications responsibilities of the controller, the
User Code must be written in User Tasks. Each User task is a simple state machine that can quickly
complete its function. A full description of the requirements of the User Tasks can be found in the “XE24S
