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.

XE24S500 COMMUNICATIONS CONTROLLER (continued)

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.

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.

FCC ID: TBD

The XE24S500 generates radio frequency energy. It

must be installed according to the manufacturer’s guide-

lines stated in the data sheet or it has the potential to

cause interference with other radio devices. Testing has

been performed to assure that it conforms with the FCC

Part 15 rules for intentional and unintentional radiators.

WARNING:

This device complies with Part 15 of the FCC Rules.

Its operation is subject to the following conditions:

(1) This device may not cause harmful interference.

(2) This device must accept any received interference

including interference that may cause undesired

operation.

No further EMI compliance testing of the transmitter is

required as long as the 20 cm separation and co-location

requirements are observed. Each new use of the module

will, however, need to be scanned for unintentional ra-

diation from digital clocks, etc.

All necessary calibration has been performed at the time

of manufacture. Any modification of the device after it

leaves the factory is a violation of FCC rules.
