| XE900SL10 June 2005 XE900SL10 Miniature Spread Spectrum Transceiver Description The XE900SL10 breaks new ground in Smart Transceiver Technology. It is a 900 MHz, Spread Spectrum Transceiver with integral micro-controller, just 1 inch square. This miniature size combined with low power consumption make the XE900SL10 perfect for mobile and battery powered applications. Xecom did not drop features to reduce size. The XE900SL10 still supports Xecom's Count-OffTM feature enabling a scan of up to 125 remote nodes in under 10 seconds. SensorOnAirTM allows sensors and control lines to utilize the embedded communications controller in place of a host micro-controller . Xecom also offers a high power spread spectrum model, the XE900S-500, for applications that require greater range. The XE900S-500 has an obstructed range of up to 1000 feet in a larger but still small package. The XE900SL10 transmits at up to 10 milliwatts with a receive sensitivity of -100 dBm to provide an obstructed range of 300 feet. All from a 1 inch square transceiver consuming less than .2W of power.

This makes it easy to accommodate applications which include nodes with both long range and short range requirements. The XE900S-500 and XE900SL10 can share board layout because of common pin assignments. Pins 1 through 8 of the XE900SL10 are equivalent to Pins 3 through 10 on the XE900S-500; they have the same functions and are placed in the same sequence. Pin 9 on the XE900SL10 is an unused pin and therefore does not conflict with the ADC1 signal assigned to Pin 11 of the XE900S-500. The XE900SL10 requires a separate pin row for Pins 10 through 14. These pins will be hidden under the XE900S500 module when the larger module is installed. The XE900SL10 also includes one unique signal, Reset. Reset is an active high signal that can be left unconnected if no external reset is desired. The figure below shows the overlapping layout that supports both modules. The XE900S-500 outline and pins are shown in green. XE900SL10 pins and outline are shown in red.

The #P command determines how the transceiver will operate when not being asked to transmit or receive an RF signal. Below are descriptions of all of the XE900SL10 operating modes. IDLE: In Idle Mode all circuits within the XE900SL10 are powered and available for immediate action. This includes the RF receiver which actively monitors the air for an incoming communications request. Current draw in Idle Mode is typically 18 milliamps. SLEEP: In Sleep Mode all circuits within the XE900SL10 are powered-down to reduce consumption. The XE900SL10 will not accept commands or respond to incoming RF communications requests. Any input on the TXD line will wake the transceiver and return it either the Idle or Power-Down Mode which ever mode it was last in before being put into Sleep Mode. Current draw in Sleep Mode is less than 40 microamps. Power-Down: In Power-Down Mode all RF circuitry is shut down but the communications controller remains active to accept AT commands. In this mode the XE900SL10 cannot respond to incoming RF communications requests. If a Transmit RF or Receive RF command is received, the XE900SL10 can activate the RF section in under 200 microseconds. Current draw in Power-Down Mode is less than 500 microamps. RF Monitor Mode: The XE900SL10 RF monitor mode has 4 settings. At each of these settings the transceiver sits in power down mode for a prescribed period of time. The transceiver then wakes up, turns on its receiver and checks for incoming messages. If no messages are received the transceiver returns to power down mode after about 200 milliseconds. If a carrier is detected, the transceiver completes the transaction before returning to power down mode. Intervals of 2 seconds (#P3), 4 seconds (#P4), 8 seconds (#P5) and 16 seconds (#P6) can be chosen. RF Receive Mode: In RF Receive Mode the XE900SL10 is actively receiving an incoming 900 MHz data signal. Current draw in RF Receive Mode is less than 30 milliamps. RF Transmit Mode: In RF Transmit Mode the XE900SL10 is actively transmitting a 900 MHz data signal. Current draw in Transmit mode is no more than 55 milliamps with the transmit output power set to maximum, 10 milliwatts. AT Command Control The low power modes are controlled by the AT#Pn command, see below. AT#P0 - Sets the transceiver to Idle mode. AT#P1 - Sets the transceiver to Sleep Mode. AT#P2 - Sets the transceiver for Power-Down Mode. AT#P3 - RF Monitor Mode (2 second interval) AT#P4 - RF Monitor Mode (4 second interval) AT#P5 - RF Monitor Mode (8 second interval) AT#P6 - RF Monitor Mode (16 second interval) XECOM (4) XE900SL10 XE900SL10 PIN CONFIGURATION /TXD /RXD /CTS /RTS DIO3 DIO2 DIO1 DIO0 N/C 1 2 3 4 5 6 7 8 9 Antenna XE900SL10 Top View 14 13 12 11 10 Reset ADC0 ADC1 VCC GND SIGNAL /TXD /RXD /CTS /RTS DIO3 DIO2 DIO1 DIO0 N/C GND VCC ADC1 PINS 1 2 3 4 5 6 7 8 9 10 11 12 DESCRIPTION Transmit Data is the data input to the XE900SL10.

This micro-controller manages the interface to the host system, determines when the communications link is available, and formats data for the RF communications. HOST INTERFACE There are two primary interfaces between the XE900SL10 and the system host; the serial interface and the direct sensor interface supported by the SensorOnAirTM feature. Management of both interfaces is the responsibility of the communications controller. Serial Interface A 4-signal serial interface links the host to the XE900SL10. For most applications the XE900SL10 acts as a DCE. Control and configuration of the XE900SL10 takes place through the serial interface using modem-like AT commands. Serial data rates from 1200 bits per second to 115.2K bits per second are supported. The serial interface signals are listed below. /TXD - Transmit Data; the input to the XE900SL10 for AT commands and Data to be transmitted on the wireless network. /RXD - Received Data; the output from the XE900SL10 for received RF data and responses to AT commands. /RTS - Request to Send, provides the hardware flow control input to the XE900SL10. The DTE deactivates /RTS to stop the XE900SL10 from sending more data on the RXD line. /CTS - Clear to Send, is the hardware flow control output from the XE900SL10. The XE900SL10 deactivates /CTS to advise the host to stop inputting data on the TXD lead. XE900SL10 AT Command Format AT commands issued to the XE900SL10 follow a strict format. Each command begins with the prefix AT and ends with a carriage return. The XE900SL10 communications controller accepts commands at data rates from 1200 to 115,200 bps. The default serial data rate is 9600 bps and can be changed using register S23. The communications controller uses the AT command prefix to automatically determine the parity of the incoming characters. Command Prefix - Each command, except the A/ command, 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 XE900SL10 by comparing the parity bits of the "A" and the "T" characters. Command Line - Commands may be strung together in a single command line of up to 30 characters. Commands in the command string are executed in the sequence they appear. Omitted Parameters - Most 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. Result Codes - A result code is normally issued after each action. Result codes may be provided as full words, one or two digit numeric codes, or may be disabled all together. Each result code ends with a carriage return when numeric result codes are chosen. When full word result codes are chosen, a Line Feed and Carriage Return precede and follow each result code. Disconnect Sequence - A three character sequence initiates a disconnect of the wireless link. The sequence "~~~" is assigned to disconnect the link. DIRECT CONNECTION OF SENSORS: SensorOnAirTM Sensors can be connected directly to the XE900SL10 without requiring an applications controller. In this SensorOnAir TM configuration the XE900SL10 communications controller controls the operation of the sensors. Sensor I/O Lines SensorOnAir controls the operation of 6 I/O lines to the XE900SL10. This includes 2 analog inputs, ADC0 and ADC1, 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 using 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. XECOM (8) XE900SL10 XE900SL10 COMMUNICATIONS CONTROLLER Configuring the XE900SL10 for Sensor Operation All SensorOnAir control functions for the analog inputs and digital I/O's are performed by the communications controller within the XE900SL10. Modem-like AT commands loaded through the serial interface, program the functions of the analog and digital I/O lines. The AT commands used to program the SensorOnAir functions are then stored in the XE900SL10's Flash memory. This allows the XE900SL10 to be first programmed and then installed in the application. The communications controller uses the information stored in Flash memory to control the analog and digital I/O lines. SensorOnAir CommandsTM Below is a list of the AT commands used to program the direct control of sensors using the communications controller in the XE900SL10. S107 Defines the function of the programmable I/O lines. The two analog input lines, ADC0 and ADC1, can also be defined as digital I/O lines if needed. The four programmable digital I/O lines, DIO0, DIO1, DIO2, and DIO3; can be set as either inputs or outputs. The value of this command is stored in flash memory within the XE900SL10. WIRELESS COMMUNICATIONS The communications controller manges the RF Link. This includes the frequency hopping algorithm for spread spectrum operation; collision avoidance, node addressing, and packetizing data. The communications controller allows support for point-to-point, point-tomultipoint or multipoint networks. Carrier Sense Multiple Access (CSMA) To prevent collisions between network nodes the XE900SL10 uses a Carrier Sense Multiple Access protocol for each network transceiver. In normal communications all nodes, including the Master node in a point-to-multipoint network, listen for communications activity before initiating a session. If a wireless link already exists, the transceiver waits until that session is complete before initiating a wireless link. Data Packets All data presented by the system host is placed into packets by the XE900SL10 communications controller for transmission across the wireless link. These packets provide addressing and error correction for the wireless communications. The communications controller places the data in packets only for the wireless link. The data is extracted from the packets before being sent out the serial interface. File Transfer Mode Xecom's XE900SL10 incorporates a File Transfer mode that uses a simplified networking protocol so that the maximum data transfer rate is achieved. In this mode the XE900SL10 does not automatically retransmit blocks containing errors. A CRC 16 checksum is calculated, transferred at the end of the file, and checked by the receiving unit. An "ERROR" message is displayed if the checksum calculated at the receive end does not match the checksum transmitted with the data. The File Transfer Mode is controlled by the AT#T command. The format of the command is AT#Txx; where xx is the destination address of the file. Following is a sample file transfer. 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 read the status of Digital I/O "n." AT&IDn=z - This command allows a local host equipment to set the condition of the local 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. AT#IxxxDn? - This command allows the status of Digital I/O "n" on node address "xxx" to be read remotely AT#IxxxDn=z - This command allows the condition of the local 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. XECOM (9) XE900SL10 XE900SL10 COMMUNICATIONS CONTROLLER Sample File Transfer Transmitter TXD AT#T01 Notes: The above example shows that the file transfer is assumed to be completed if three seconds pass with no data being presented to the TXD input on the serial port. File Transfer Mode cannot be used to send binary data. Multipoint Network 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 the AT#E: or AT#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.

To comply with FCC RF exposure requirements for mobile transmitting devices, this transmitter should only be used or installed at locations where there is at least 20 cm separation distance between the antenna and all persons. FCC Notifications The XE900SL10 generates radio frequency energy. It must be installed according to the manufacturer's guidelines 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. 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 radiation 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.
