Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 3 OF 12 CONFIDENTIAL INSTALLATION STEPS FOR EVALUATION KIT SOFTWARE The USB key in the evaluation kit contains multiple SW components that can be installed for evaluating the various applications on the evaluation board. System Requirements: PC with Windows XP Service Pack 2 or Windows Vista. with at least one Ethernet port, and a PC with a serial or USB port. (A single PC can provide both the serial and Ethernet connections, if desired.) Install Java Runtime Environment If you have Java Runtime Environment (JRE) Version 6 Update 14 or later, you should be able to run the GSDemo GUI application that are installed as part of the Eval kit installation. If not, you can download the current version of JRE from http://www.java.com/en/download/manual.jsp or run jre-6uXY-windows-i586-p-s.exe from the USB flash drive received with your Evaluation Kit, where XY may vary depending on the update provided. Install Serial Terminal Software Install the Tera Term serial terminal software (teraterm_utf8-4.58.exe). If you already have tera term or use a different terminal software, then you can skip this step. Evaluation Kit Software Installation Installs the Serial to Wi-Fi application binaries, GSDemo GUI for the temperature and light sen-sor application and drivers required for serial configuration. Run evalkit_setup.exe from the USB flash drive. This starts the InstallShield Wizard. Perform a “Typical” installation, using all default settings. This creates and populates the C:\GainSpan\EvalKit\X.X.X directory. Note: Directory names and organization may differ slightly from one release to another; If you have already installed earlier versions of GainSpan software, the most recent release will be add-ed in a separate folder. Copy Sim_terminal.exe from the USB key to the EvalKit directory created in this step. The sim terminal is a serial terminal with --- TCP/UDP client available from GainSpan. Note that Simple Terminal requires the .NET framework, 2.0 or above; You can download that .net framework from http://www.microsoft.com/downloads/en/default.aspx USB/UART Cable Driver Installation Note: If using RS232 (DB9) cable, then this step can be skipped If USB to UART cable provided with the kit is used, then install the driver for this cable from C:\GainSpan\S2wEvalKit\1_1_2\drivers\usb_uart directory that was created previous step. The file is labeled CDM 2.02.04.
Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 4 OF 12 CONFIDENTIAL SERIAL TO WI-FI SETUP AND START UP INSTRUCTIONS Below are the steps required to run the serial to Wi-Fi application. 1. Once the software installation is completed, power the Wi-Fi Access Point (AP). The access point have been pre-configured with the following parameters: a. SSID = “GainSpanDemo b. Channel = 6 c. DHCP = Enabled d. Security = Open e. IP Address = 192.168.3.1 Note: If user wants to use a different AP than the one provided with the kit, user can use any standard Wi-Fi (802.11 b/g/n) AP, they should just ensure that the AP settings match the parameters above. 2. Plug the serial cable provided directly into a serial communications port of the PC if one is available, or into a USB-to-serial converter. Since USB converters can enumerate to any one of a number of COM ports, it is necessary to find the COM port of the serial port or USB converter being used to communicate with the board. Open the Device Manager (Figure 1): Start → Settings → Control Panel → System → Hardware → Device Manager. The USB Serial Port is listed under Ports (COM & LPT), as shown below. Figure 1: System Properties pane with Device Manager Button

Connect the Serial Cable provided with the kit to either the 6-pin UART connector as shown be-low or to the DB9 connector depending on the type of cable that is being used. Black WireIndicates Pin 1Pin 1Black WireIndicates Pin 1Pin 1 3. Launch the Tera-Term Application. Select serial port connection, and select the serial port identi-fied in step 2. Set the port settings as shown below. 4. Install the batteries provided with the kit into the battery holder. NOTE: Make sure the power switch (SW1) is in the OFF position. Make sure that the battery’s positive (+) terminal aligns with the battery holder’s positive (+) terminal indicator before inser-tion. Improper placement of the battery may damage the evaluation board. SW1On OffSW1On Off 5. Power on the Evaluation board by switching the power switch SW1 to the “ON” position. Tera-Term will display “Serial to WiFi App” for an internal PA board (GS1011MIP-EVB) or “Serial to WiFi App-Ext. PA” for an external PA board (GS1011MEP-EVB or GS1011MEE-DB). 6. By default the board will not have a network setup. To look at the network stat type “at+nstat=? In the tera-term window. To look for available wireless networks and associate with one, below are the steps a. To scan for available Wi-Fi access points, type “at+ws” on the Tera-Term screen
Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 6 OF 12 CONFIDENTIAL b. To associate with the GainSpanDemo AP, first enable DHCP client, by typing “at+ndhcp=1” and then type “at+wa=GainSpanDemo”. The evaluation board will re-ceive an IP address from the Access Point DHCP server. c. Type at+nstat=? To show the current status of the network connection. 7. Type “AT?” This will list all the supported AT command set so you can develop your applica-tion using either HOST MCU through the serial interface or HOST PC using the Serial Terminal Application. See the Serial to Wi-Fi Adapter guide and command reference guide for details on all the AT command set and a quick list of AT commands respectively.
Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 7 OF 12 CONFIDENTIAL The evaluation kit installer loads various software components including the WLAN firmware and user application binaries for evaluation. The two main types of application binaries installed are Serial to Wi-Fi and Temperature and Light Sensor Application. The directory structure looks like the figure below. The Serial to Wi-Fi Application contains multiple example applications. Below is a list of the binaries and a short description for each Directory Description Web Server Provisioning Application with AT command to support embedded WebServer and Web pages for provisioning. This is the default binary loaded on all the evaluation boards. The directory also contains binaries for testing firmware update. (See App Note 39 for Web provisioning steps) Wi-Fi Protected Setup (WPS) Application with support for AT command to evaluate Wi-Fi Pro-tected Setup. (See App Note 39 for WPS steps) RF Test Binaries Application with support for AT command to do RF testing i.e confi-guring radio for FCC modes like continuous transmission Enterprise Security (EAP) Application with support for AT commands for Enterprise EAP types – EAP-TLS, EAP-TTLS, EAP-FAST The Temperature and light sensor application (TLS) is not a serial to Wi-Fi application, but a different reference application that utilizes the GEPS API’s to develop a sensor device. It uses SNMP for configu-ration and communicates with the GSDemo PC GUI application that is installed by the kit. The TLS di-
Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 8 OF 12 CONFIDENTIAL rectory includes binaries for two types of modules. For details on how to setup and run the TLS applica-tion see the Temperature and Light Sensor and GSDemo User Manual. Directory Description Ext_pa TLS application binaries for supporting External PA Module. If board contains a GS1011MEP or GS1011MEE module, then down-load this binary set into the module Int_pa TLS application binaries for supporting Internal PA Module.

Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 9 OF 12 CONFIDENTIAL REGULATORY NOTES Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interfe-rence by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. FCC Caution: To assure continued compliance, (example - use only shielded interface cables when con-necting to computer or peripheral devices). Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference re-ceived, including interference that may cause undesired operation. IMPORTANT NOTE: FCC & IC Radiation Exposure Statement: This equipment complies with FCC & IC radiation exposure limits set forth for an uncontrolled environ-ment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance require-ments required with this module installed (for example, digital device emissions, PC peripheral require-ments, etc.). IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop confi-gurations or co-location with another transmitter), then the FCC & IC authorizations are no longer consi-dered valid and the FCC & IC IDs cannot be used on the final product. In these circumstances, the OEM
Serial to Wi-Fi Start Up Guide PRELIMINARY PAGE 10 OF 12 CONFIDENTIAL integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining separate FCC & IC authorizations. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users (for example access points, routers, wireless ADSL modems, and similar equipment). The final end product must be labeled in a visible area with the following: “Contains FCCID: XXXXXXX & IC: XXXXXXX”. IC Certification — Canada The labeling requirements for Industry Canada are similar to those of the FCC. A visible label on the out-side of the final product must display the IC labeling. The user is responsible for the end product to comp-ly with IC ICES-003 (Unintentional radiators) Manual Information That Must be Included The user’s manual for end users must include the following in-formation in a prominent location. IMPORTANT NOTE: To comply with FCC & IC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Other notes: GainSpan modules have been built or under development for near body exposure applications. The 20cm statement is a standard note because absorption rate testing (commonly known as SAR or Specific ab-sorption rate) is not modularly transferable for FCC/IC. Thus, if a radio is being used against the body, the end user is still responsible to test for regulatory near body exposure testing (for USA, please refer to the following): • FCC Part 1.1037 • FCC Part 2.1091 Mobile Devices • FCC Part 2.1093 Portable Devices • FCC Part 15.247 (b) (4)
