The module provides a variety of hardware interfaces that may be active at any time. There are two UARTs, each providing an asynchronous communication interface supporting all standard bit rates up to 921.6 kbps. Both UARTs support hardware flow control, if enabled. Two SPI interfaces provide dual synchronous serial communication and operate in either slave or master modes. SPI 0, when configured as a master device, provides up to four chip selects. One I 2 C port is provided supporting bit rates of up to 392 kbps. Three Pulse-Width Modulation (PWM) outputs are provided. The PWM outputs operate in two modes; as independent function blocks providing an output signal with programmable frequency and duty cycle, or as synchronized PWM function blocks with programmable phase delay between each PWM output. Two ADC inputs provide 10-bit A-to-D conversions at up to 32 ksps. ADC 0 can be configured as a DAC providing 10-bit D-to-A conversions. When ADC 0 is used as a DAC, ADC 1 is disabled and should be left unconnected. Unused pins are available as General Purpose I/O (GPIO), which may be programmed as Input (default), Output or Bi-Directional. Two Alarm inputs are provided to wake the WiFi-IT from the power conservation sleep mode. The Alarm inputs have programmable polarity and are Schmidt-triggered logic. The Ready output goes active when the module is ready to communicate. FIRMWARE DESCRIPTION The WiFi-IT module is available preloaded in two different configurations. The Wireless-Wire (L1) configuration requires no programming, just use the configuration application to setup your desired operation parameters. The WiFi-IT Basic (L2) application provides a Basic language interpreter, enabling the engineer to design, code and debug their own applications. Using the WiFi-IT! Module and WiFi-IT Basic you can replace the microprocessor in many embedded designs! WIFI-IT! WIRELESS-WIRE The Wireless-Wire application supports configuration of a nodes interface ports and control engine. It is also used to setup the wireless communication parameters either remotely or through an RS232/USB port on a Personal Computer. Interface ports can be enabled and configured with the desired operating parameters. The node control engine can me setup to operate in three unique modes: 1. Sleeping sensor node with timer or interrupt auto-reporting. 2. Sleeping data node with timer or interrupt auto-reporting. 3. Always-on node with interrupt, timer or continuous connection. Once configured the WiFi-IT node permanently stores the settings and will operate, using those settings, until they are changed. The Wireless-Wire Configuration application can update node operating parameters over the wireless network at anytime. WiFi-IT!™ WLAN Module www.npe-inc.com Page 3 of 16 ©2009 by NPE, Inc. v1.3 WL10-G - 3/19/2010 WL10-G The Wireless-Wire protocol supports UDP communication between the node and an Access Point. Communication between a Microsoft Windows® PC and the WiFi-IT nodes is directly supported through a supplied virtual COM port (vCOM) driver. Once the vCOM port is created the connection to the embedded system containing the WiFi-IT node operates just as a wired connection. Data can be transferred from the embedded system or sent to the embedded system through the vCOM port. When operating with legacy RS232 equipment, no modifications to the legacy communication protocol need to be made, in many instances. The Wireless-Wire wraps the legacy communication messages in its own protocol for transmission and removes the wrapper before forwarding the communication on to the legacy system. ` Wireless-Wire Configuration WiFi-IT! Control Software & vCOM Figure 1: L1 System When operating in one of the sleep modes there may be a latency period until the node leaves the sleeping state and connects to the WLAN. The vCOM port can be configured to buffer messages until the node is available. WIFI-IT BASIC (L2) APPLICATION The WiFi-IT Basic application provides a higher level of control requiring programming to implement a solution. Using the WiFi-IT development environment with WiFi-IT Basic, sophisticated programs can be written providing direct program control of an embedded system. WiFi-IT Basic provides a simplified Application Programming Interface (API) to the WLAN, special sleep modes and control of the hardware interfaces. The WiFi-IT development environment provides tools to debug the a…

Bagdons Cover Letter for request for a Limited Single Modular Approval FCC ID: XRH-1997 This request is for a Single Modular Approval. This unit is a module that operates in the 2400 to 2483.5 Mhz frequency band. The above FCC ID product is a plug in module board that is plugged in as a daughter board to the Main host board and provides wireless communications in the 2400 to 2483.5 Mhz frequency band. • (i) “The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements.” This EUT (FCC ID: XRH-1997) Has its own shielding of the radio elements • (ii) “The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates by over-modulation.” The processor chip in this module is a Gainspan GS1010WiFi ultra low power wireless single chip The control of the output data stream is controlled by the internal firmware and logic design in this chip to prevent excessive data rates by over modulation. • (iii) The Modular transmitter must have its own power supply regulation. A linear voltage regulator (NCP700MN180R2G) is provided on the modular board to provide power to the Gainspan chip. • (iv)The modular transmitter must comply with the antenna and transmission system requirements of Sections 15.203, 15.204 (b) and 15.204 (c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. Two antennas were tested with this EUT. (1) is a Chip antenna (PC Board mount) Antenna Facdtor, Inc. Model: ANT-2.45-CHP-x that has a gain of 0.5 dBi and (2) an external antenna made by Taoglas Model: GW.11.A153 which has a maximum gain of +1.8 dBi. There are no adjustments on the EUT. • (v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with Part 15 requirements.

North Pole Engineering, Inc. WiFi IT WLAN Module Model: WL10-GC Operational Description The WiFi-IT module is made up of two main subsystems; the Application processor (APP) and the WLAN processor. The WLAN subsystem provides the WLAN PHY, MAC and baseband functionality. It contains the WLAN CPU, a 32-bit ARM7 TDMI-S core running at up to 44 MHz. It includes an IEEE 802.11b/g -compatible RF transceiver, which supports Direct Sequence Spread Spectrum (DSSS) 1 Mb/s and 2 Mb/s data rates. The WLAN sub- system includes an integrated power amplifier, and provides management capabilities for an optional external power amplifier. In addition, it contains engines for AES and RC4 data encryption/decryption, CRC computation, and IEEE1588 precision time protocol network clock synchronization. The WLAN subsystem contains the control logic and state machines required to drive the low power DSSS modem, and perform pre-processing (in transmit mode) or post-processing (in receive mode) of the data stream. The WLAN subsystem manages DMA accesses, data encryption/decryption using the AES algorithm, and CRC computation. The WiFi-IT uses the internal PA to reduce the number of external components required for Wireless LAN connectivity. The internal power amplifier delivers 9 dBm (typical) into a differential balanced 100 ohm load. Its outputs are merged with the LNA inputs through a transistor structure replacing the traditional external TX/RX switch. This solution reduces the off-chip RF BOM to a single low-cost LTCC band pass filter, which also provides differential-to-single-ended conversion. The WiFi-IT App processor runs a program that operates the device interfaces, I2C, UART, SPI, ADC and PWM, to control the attached sensor devices. The data read from the devices can be processed locally and transmitted back to the network through the WLAN processor. The devices connected to the interfaces, are controlled by the code that runs on the APP processor allowing the user to connect a multitude of sensors and provide on-board intelligent decision making capabilities.

None 4 of 43 International Certification Services, Inc. Applicable Standards 47 CFR Ch.1 (07-10-2008 Edition) FCC Part 15 Radio Frequency Devices (July 10, 2008) Subpart C Intentional Radiators Section 15.249 Operation within the bands 902-928 Mhz, 2400- 2483.5 Mhz, 5725-5875 Mhz and 24.0 to 2425 Ghz. Section 15.212 Modular Transmitters 2.1 Referenced Standards ANSI C63.4-2003 Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 Khz to 40 Ghz. 2.2 Equipment Units Tested The equipment tested was a modular 2.4 Ghz Wireless Network module. This device is a module that takes power from a HOST equipment and post regulates this voltage to the necessary voltages to operate the modular EUT. The Transmitter chip that is used in the design is a Gainspan GS1010 WiFi. There are two antennas that can be configured with this device, one is an external stick type antenna (Taoglas GW.11.A153: Model: WL10-GS) and the other antenna is an internal PC board mounted chip antenna (Antenna Factor ANT- 2.45-CHP-T,B; Model: WL10-GC). The external Stick antenna has a reverse SMA connector as required by FCC 15.203. It can only be configured with one antenna at a time. It is a Digital Modulated Transmitter (DTS) that operates on up to 14 channels in the 2.4 to 2.4835 Ghz frequency band. The transmit time is controlled by the internal firmware of the chip and is compatible with the 802.11 b/g requirements. This module has an on board post regulator to control the voltage to the Intentional Radiator circuitry per the requirements of FCC 15.212 (a) (1) (iii). 2.3 Equipment and Cable Configuration See photo of the EUT test configuration setup in Attachment A 2.4 List of Test Equipment Test Equipment Spectrum Analyzer Harmonic Mixer RF Amplifier Preamp Biconical Antenna Log Periodic Antenna (200-1000 MHz) Horn Antenna (1-18 Ghz) Horn Antenna (18-26 Ghz) Model Hewlett-Packard 8566B Hewlett Packard 11970K Hewlett Packard 11975A Nextec Model: NB00391 EMCO 93110B EMCO 3146 EMCO 3115 Alpha Industries 61932500 S/N 2421A00458 3003A04385 2738A01733 378 105799 9111-3280 2334 55 Calibration Date 01/25/08 10/10/08 09/30/08 06/09/08 06/22/09 01/23/08 06/23/09 01/23/08 5 of 43 International Certification Services, Inc.
