DWE-XE900S-500Transceiver Module

XECOM(1)XE900S-500 XE900S-500 June 2004 XE900S-500 Smart Spread Spectrum Transceiver Description The XE900S-500 combines a spread spectrum transceiver and micro-controller in a single, easy-to- use, FCC Part 15 Registered module. The embedded communications controller manages the Frequency Hopping Spread Spectrum (FHSS) link and the host system interface. The XE900S-500 supports two unique features to simplify wireless networking. Count-Off™ allows the network master to quickly retrieve the status of 253 remote nodes with a single broadcast command. SensorOnAir TM eliminates the need for an application controller by utilizing the communications controller to directly manage analog inputs and digital control lines. Xecom also offers a low power spread spectrum model, the XE900SL10, for applications that require less range. The XE900SL10 has an obstructed range of 300 feet but is smaller, costs less and uses significantly less power. Features *Small Size: 1.295” by 1.410” by 0.255” *Serial Control and Configuration of the Wireless Link. *Supports a 254 node point-to-multipoint network * Programmable Transmit Power Output 100 to 500 mW. *Typical Receiver Sensitivity -100 dBm *Obstructed signal range to 1500 feet; *Wireless Data Rate 76.8K bps, half-duplex *Low power Consumption XE900S-500: 1000 mA @ 3.3 Volts; when transmitting at 500 mW output power; less than 1 mA of current flows in Sleep Mode or Power-Down modes *SensorOnAir TM allows direct connection of sensors to the Smart Transceiver *Count Off allows the host node to download the status of all nodes in under 10 seconds. * Operating Temperature Range of -40 to +85 C *FCC Part 15 Registered XE900S-500 Block Diagram Analog Inputs Antenna MUX AMP COMM.

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 the commonality of 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 XE900S- 500 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 XE900S-500 operating modes. IDLE: In Idle Mode all circuits within the XE900S-500 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 23 milliamps. SLEEP: In Sleep Mode all circuits within the XE900S-500 are powered-down to reduce consumption. The XE900S-500 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 100 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 XE900S-500 cannot respond to incoming RF communications requests. If a transmit RF or Receive RF command is received, the XE900S-500 can activate the RF section in under 200 microseconds. Current draw in Power-Down Mode is less than 800 microamps. RF Receive Mode: In RF Receive Mode the XE900S-500 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 XE900-500 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.

Response to TCB Findings 1. It appears there are 2 power settings 20dBm and 27dBm for the module. Please clarify all the differences between the 20dBm and 27dBm models in details if there are any. Power Settings are controlled by an AT Command. Please refer to page 13 of the Users Manual, Paragraph S108 for the settings that are available. Unit is always shipped in the maximum setting. 2. Are the Temple Star C-522 antenna (in conducted test report) and the Xecom XE900A500 antenna (in manual) the same? Please clarify. Yes, both antennas are the same. Xecom has renamed the Temple Star C-522 with their own product number of XE900A500. 3. Has the device antenna positions been adjusted to maximize emissions? Please clarify. Testing in all three orthogonal positions of the antenna performed. Updated report attached. 4. Please specify the VBW setting used for radiated emissions with "Peak" detector on page 12 of the report. L.S. Compliance / Per Mr. Ken Boston ... RBW = 1MHz > 1GHz and VBW = 1MHz > 1GHz.

XE900S-500 900 MHZ TRANSCEIVER THEORY OF OPERATION XECOM, INC. 374 Turquoise Street Milpitas, CA. 95035 Title: XE900S-500 Theory of Operation 2 OF 2 The Xecom XE900S-500 Transceiver Module is a frequency hopping spread spectrum transceiver operating in the 902 MHz to 928 MHz ISM band. It transmits with a maximum power of 0.5 watts (+27 dBm) into a fixed ¼ wave monopole antenna with a nominal gain of 0 dBi. Transmission occurs on a pseudo-randomly ordered group of 50 channels determined are chosen from a pool of 52 available channels. Each radio is programmed with a seed value that determined the table based on a defined pseudorandom generator. Each channel carries a single packet of information for a duration no longer than 52 mS. The receiver is a direct (zero IF) conversion type meaning that there is no offset local oscillator. Individual channel selection occurs within the receiver without the need for external filtering. An overall bandpass filter restricts the receiver to the stated ISM band.

Introduction On March 26 th , 29 th , 30 th and April 2 nd & 5 th , 2004 a series of Radiated Emission tests were performed on one sample of the Xecom 900 S 500 Module, here forth referred to as the “Equipment Under Test” or “EUT”. These tests were performed using the procedures outlined in ANSI C63.4-2001 for intentional radiators, and in accordance with the limits set forth in FCC Part 15.247 (Industry Canada RSS-210) for a low power transmitter. These tests were performed by Kenneth L. Boston, EMC Lab Manager and Thomas T. Smith, EMC Engineer of L.S. Compliance, Inc. All Radiated and Conducted Emission tests upon the EUT were performed to measure the emissions in the frequency bands described in Title 47 CFR, FCC Part 15, including 15.35, 15.209, 15.247 and Industry Canada RSS-210 to determine whether these emissions are below the limits expressed within the standards. These tests were performed in accordance with the procedures described in the American National Standard for methods of measurement of Radio- Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (ANSI C63.4-2001). Another document used as a reference for the EMI Receiver specification was the Comite International Special Des Perturbations Radioelelectriques (CISPR) Number 16-1, 2002. 8. Product Description The Xecom 900 S 500 Transceiver is a compact frequency hopping spread spectrum 900 MHz transceiver. It is a low power, 500 mW output device with a simple series interface capability. It is based on the Xemics XE1203 transceiver chipset and the T.I. MSP430 microprocessor, and operates with a ¼ wave monopole antenna. L.S. Compliance, Inc. Page 9 of 25 Test Report Number: 304192 TX (TCB Rev. 1) Prepared For: Xecom 9. Test Requirements The above mentioned tests were performed in order to determine the compliance of the EUT with limits contained in various provisions of Title 47 CFR, FCC Part 15, including: 15.207 15.247b 15.247e 15.205 15.247c 15.109 15.247a 15.247d 10. Summary of Test Report DECLARATION OF CONFORMITY The Xecom 900 S 500 Module was found to MEET the requirements as described within the specification of Title 47 CFR …
