Using the XE24S500 Power Saving Modes
The XE24S500 includes three low power operating
modes (Sleep, Power-Down and RF Monitor) to
allow the host application to make maximum use of
the available power. The #P command selects the
transceiver operating mode when it is not actively
transmitting or receiving data. Below are
descriptions of all of the available selections.
RF MONITOR MODE: RF Monitor Mode holds
the transceiver in power down mode for an interval
set by Register S110. The transcevier then
activates, turns on its receiver, and checks the air
for incoming messages. If no messages are
detected within 200 milliseconds, the transceiver
returns to power down mode. If carrier is detected,
the transceiver completes the transaction before
returning to power down mode. S110 selects an
interval of 1 to 60 seconds. Power consumption in
RF Monitor Mode ranges from 1 to 10 milliamps
depending upon the setting.
IDLE: In Idle Mode all XE24S500 circuits are
powered and available for immediate action. This
includes the RF receiver which actively monitors
the air for an incoming communications request.
SLEEP: In Sleep Mode all XE24S500 circuits are
powered-down to minimize power consumption.
The XE24S500 cannot accept commands or
respond to incoming RF communications requests
from Sleep mode. Any input on TXD will wake the
transceiver and return it to the previous mode,
either the Idle or Power-Down Mode Current
draw in Sleep Mode is less than 50 microamps.
RF RECEIVE MODE: In RF Receive Mode the
XE24S500 is actively receiving an incoming data
signal. Current draw in RF Receive Mode is
typically 30 milliamps.
RF TRANSMIT MODE: In RF Transmit Mode
the XE24S500 is actively transmitting a data signal.
Current draw in Transmit mode is no more than
700 milliamps with the transmit output power set
to maximum, 500 milliwatts.
POWER-DOWN: In Power-Down Mode all RF
circuitry is shut down but the communications
controller remains active to accept AT commands.
The XE24S500 cannot respond to incoming RF
communications requests. If a transmit RF or
receive RF command is received, the XE24S500
can activate the RF section in under 200
microseconds. Current draw in Power-Down
Mode is less than 2 milliamps.
AT COMMAND CONTROL
The XE24S500 power saving modes are controlled
by the AT#Pn command as described below.
AT#P0 Select Idle mode.
AT#P1 Select Sleep Mode.
AT#P2 Select Power-Down Mode.
AT#P3 Select RF Monitor Mode
RF MONITOR INTERVAL: S110=n
Values of 1 to 60 set the RF Monitor interval in 1
second increments

XE24S500 COMMUNICATIONS CONTROLLER
Command Line - Commands may be strung
An internal micro-controller serves as the XE24S500
communications controller. This micro-controller
manages the host interface, manages the wireless
link, and formats data for the RF communications.
together in a single command line of up to 30
characters. Commands in the command string are
executed in the sequence they appear. An
“ERROR” response will be issued if the command
buffer is overfilled and none of the commands will
be executed.
HOST INTERFACE
The XE24S500 has two primary system interfaces;
the serial interface and the direct sensor interface
supported by SensorOnAir™. The communications
controller manages both interfaces.
Omitted Parameters - Many commands include a
parameter which determines the function setting.
When the command parameter is omitted from the
command string, it is assumed to be a 0.
Serial Interface
The XE24S500 supports a 4-line serial interface.
Control and configuration of the transceiver takes
place through the serial interface using modem-like
AT commands. The serial data rate is configurable
from 1200 to 115.2K bits per second. The supported
serial interface signals are listed below.
Result Codes - Result codes are normally issued
after each action. Result codes may be provided as
full words, numeric codes, or may be disabled.
When numeric result codes are chosen, each result
code ends with a Carriage Return. Full word result
codes are preceded and followed by a Line Feed
and Carriage Return.
TXD - Transmit Data; input for commands and for
Data to be transmitted on the wireless link.
Disconnect Sequence - A 3-character sequence
RXD - Received Data; the output for received RF
data and responses to AT commands.
initiates a disconnect of the wireless link.
The
sequence “~~~” is assigned to disconnect the link.
/RTS - Request to Send, hardware flow control
input. The host raises /RTS to tell the
XE24S500 to stop passing data on RXD.
DIRECT CONNECTION OF SENSORS
SensorOnAir™ permits sensors to be connected
directly to the XE24S500 without an application
controller. The XE24S500 communications controller
controls the operation of the sensors.
/CTS - Clear to Send, is the hardware flow control
output. The XE24S500 raises /CTS to stop
data input on the TXD lead.
Sensor I/O Lines™
SensorOnAir™ controls the operation of 6 I/O lines.
This includes 2 analog inputs,ADC0 andADC1, and
4 digital I/O lines, DIO0, DIO1, DIO2, and DIO3.
ADC0 and ADC1 are connected to a 12-bit analog
to digital converter and use a 2.5 volt reference
derived from VCC as their reference voltage. The
digital I/O lines can be programmed to act as either
inputs or outputs.
XE24S500 AT Command Format
Each command follows a standard command
format as described below. Commands are
accepted at data rates from 1200 to 115,200 bps.
The default serial data rate is 9600 bps and is
changed using register S23.
Command Prefix - Each command, except A/,
begins with the AT prefix. The "A" and "T" may be
either both upper case or both lower case but cannot
be of different cases. The prefix identifies parity of
the commands sent to the XE24S500 by comparing
the parity bits of the "A" and the "T" characters.

Configuring for Sensor Operation
AT#IxxxDn? - This command allows the status of
Digital I/O “n” on node address “xxx” to be
read remotely
All SensorOnAir™ functions are performed by the
XE24S500 communications controller. Modem-like
AT commands loaded through the serial interface,
program the functions of the analog and digital lines.
The configuration is then stored in Flash memory.
This allows the XE24S500 to be programmed and
then installed in the application.
AT#IxxxDn=z -
This command allows the state of
digital output “n” on node address “xxx” to
be set remotely. When z=0 the output is set
to a logic low; when z=1 the output is set to
a logic high.
SensorOnAir Commands™
WIRELESS COMMUNICATIONS
The communications controller manages the RF Link
including the frequency hopping algorithm; collision
avoidance, node addressing, and data packets. The
communications controller supports point-to-point,
point-to-multipoint or multipoint networks.
Below is a list of the commands and registers used
to program SensorOnAir™ operation.
S107 - Defines the I/O lines. The two analog inputs,
ADC0 and ADC1, can also be defined as
digital I/O lines if needed. The four digital
lines, DIO0, DIO1, DIO2, and DIO3; can
be set as either inputs or outputs. The value
of this register is stored in flash memory.
Carrier Sense Multiple Access (CSMA)
To prevent collisions between nodes, the XE24S500
uses a Carrier Sense Multiple Access protocol at
each transceiver. All nodes listen for link activity
before initiating a session. If a wireless link already
exists, the transceiver waits until that session is
complete before initiating a new wireless link.
AT&IAn? - This command allows a local host to
read the value of Analog Input “n.”
AT&IDn? - This command allows a local host to
Data Packets
read the status of Digital I/O “n.”
Data presented by the system host is placed into
packets by the XE24S500 communications controller
for transmission across the wireless link. These
packets provide addressing and error correction for
the wireless communications. The received data
is extracted from the packets before being passed
to the serial interface.
AT&IDn=z -
This command allows a local host to
set the condition of the digital output “n.”
When z=0 the output is set to a logic low;
when z=1 the output is set to a logic high.
AT#IxxxAn? - This command allows the value of
Analog Input “n” on node address “xxx” to
be read remotely.

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.

XE24S500 COMMUNICATIONS CONTROLLER (continued)
USER CODE
TheTexas Instruments MSP430F148 microcontroller serves as the communications controller in the XE24S500
transceiver modules; however, the communications functions do not fully utilize the capabilities of the
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
User Application Programmers Guide.
