The module has an 8-pin header to connect the module to a motherboard. Note: OEM Modules must be ordered in quantities of 25 or more.

3-3 3.4 Power LED, Link LED, and Reset Button The Reset button is located behind a small hole in the case, next to the two LEDs. The Reset Button should be pressed for 6 seconds with power on and then released to reset the unit to factory default settings. The yellow LED is an indicator for the WLAN Link. A lit WLAN LED indicates the WLAN interface is associated with an access point. It does not indicate if the SoftAP is active or not. The power supply LED is located on the end of the module, next to the Antenna. When power is normal, the GREEN LED will be ON. 3.5 Power Supply The WI232 Plus can use any DC power source from 5VDC to 24VDC, marked LPS or Class 2. A typical power cube sent with the unit can supply 9VDC at 500 mA. However, there are other units that can be used as long as they are in the range of 5-24VDC and supply the proper wattage. At 9VDC, the WI232 Plus will draw approximately 110mA (.99W) so a 2 Watt power source ( 9V at 200mA) should be adequate. NOTE: The WI232 Plus is designed to be used with any properly rated power adapter from 5VDC to 24VDC, 2W maximum, marked Class 2 or LPS. NOTE: The WI232 Plus power adapter is a 2.1mm positive center power jack. The jack is equivalent to a CUI Inc. PJ-002A power jack. You can also order the WI232 Plus with a Phoenix right angle power connector and mating Phoenix terminal block plug. 3.6 Product CD The product CD sent with the WI232 Plus contains user guides and other technical documents. 3.7 Technical Specifications Table 2 - Technical Specs Category Description CPU ARM Cortex M3 class processor with on-chip Flash and SRAM Firmware Upgradeable OTA Reset Circuit Reset Button Serial Interface RS232.

4-1 4. Compliance Information Grid Connect is committed to protecting people and the environment and we are working on identifying any materials used in our processes that could pose a potential hazard to our employees, customers or the environment. In 2005, Grid Connect began the process of converting all of its products to be built without any of the banned materials. The qualification of RoHS-compliant components supplied by our vendors and the implementation of new manufacturing processes related to this Directive are fully implemented. Grid Connect will attempt to distribute only those products that comply with the RoHS2 Directive, The Waste Electrical and Electronic Equipment Directive (WEEE), The Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) directive, and the Conflict Minerals directive. 4.1 RoHS2 The RoHS Directive, officially known as Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment (recast), was published in the Official Journal of the European Union on July 1, 2011 and entered into force on July 21, 2011. The restricted substances are: 1. Lead (0.1%) 2. Mercury (0.1%) 3. Cadmium (0.01%) 4. Hexavalent chromium (0.1%) 5. Polybrominated biphenyls (0.1%) 6. Polybrominated diphenyl ethers (PBDE) (0.1%) The new RoHS Directive, also known as RoHS 2, introduces new CE marking and declaration of conformity requirements. Before placing a product on the market, a manufacturer / importer / distributor must ensure that the appropriate conformity assessment procedure is in line with module A of Annex II to Decision No 768/2008/EC has been carried out and affix the CE marking on the finished product. After January 2013, electronic products bearing the CE Mark must meet the requirements of this new directive. 4.2 WEEE Directive (2002/96/EC) The Waste Electrical and Electronic Equipment Directive (WEEE) applies to companies that manufacture, sell, distribute, recycle or treat electrical and electronic equipment and to consumers in the E.U. It covers all large and small household appliances, IT equipment, radio and audio

equipment, electrical tools and telecommunications equipment, providing the means to collect and recycle electronics products from consumers at end-of-life. The Directive aims to reduce the waste arising from electrical and electronic equipment and to improve the environmental performance of all those involved in the life cycle of these products. The requirement to mark equipment with the WEEE symbol (the crossed-out wheeled bin) went into effect as of August 13, 2005. All equipment shipped to the EU member states since the date of the directive is marked with the Wheeled Bin mark. Grid Connect has a no-charge “take-back” service that gives customers the option to return used hardware products to be recycled. Products covered by the WEEE directive shipped to EU member states may be returned at no charge. Grid Connect ensures that the products are properly recycled. This service helps reduce the impact on landfills and other disposal sites and provides an environmentally safe end-of-life solution. To send hardware products to be recycled, customers can contact Grid Connect to obtain an RMA number and we will reply with information on how to ship the product. There is no charge for the disposal but the customer must pay for shipping. After the product is returned, Grid Connect also can provide a Certificate of Custody change upon customer request. Product “take-back” regulations are constantly evolving. Current regulations do not require Grid Connect to take back its products. However, by launching a WEEE take-back program, Grid Connect demonstrates a commitment to the environment and its customers by helping them dispose of products responsibly. 4.3 REACH The Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) is a European Community Regulation related to the safe use and identification of chemicals (Regulation (EC) Number 1907/2006). REACH entered into force on June 1, 2007 with the aim of improving the protection of human health and the environment through better and earlier identification of the intrinsic properties of chemical substances. The new legislative framework under REACH shifts responsibility for the control and safety of chemicals from government authorities to industry and created the European Chemicals Agency to act as a central coordinator.

4-3 Grid Connect is an importer of articles as defined in the Regulation. However, registration requirements under Article 7 of REACH do not currently apply to articles imported by Grid Connect into the European Union because: 1. Substances are not present in the articles in quantities totaling over one ton per year 2. Substances are not intended to be released under normal or reasonably foreseeable conditions of use. Grid Connect is not categorized as a downstream user under REACH because it does not use the substances in the course of its professional activities and therefore has no applicable requirements under Article 37 of REACH. Grid Connect will continue to monitor REACH developments and will comply with any applicable requirements. As Substances of Very High Concern (SVHCs) are added to Annex XIV of the Regulation (Authorization List), Grid Connect will assess whether both of the following conditions are met: 1. The substance is present in the articles in quantities over one (1) ton per year 2. The substances are present in Grid Connect devices above a concentration level of 0.1% w/w Grid Connect shall comply with the requirements of Article 7(2) and Article 33 of the Regulation, as necessary. For informational purposes, Grid Connect has contacted its material and manufacturing vendors to verify that Grid Connect devices do not contain SVHCs. 4.4 Conflict Minerals The US Securities and Exchange Commission (SEC) issued their long awaited conflict minerals rule as required per Section 1502 of the Dodd Frank Financial Dodd-Frank Wall-Street (Financial) Reform and Consumer Protection Act. The aim of the rule is to stop companies from sourcing minerals from regions in the world where armed conflict and human rights abuses are occurring, and armed rebel groups perpetuating the conflict/abuses are profiting from it. The region specifically targeted in the rule is the Democratic Republic of Congo (DRC) and surrounding region. The new rule requires SEC registered companies to annually determine if any tin, tantalum, tungsten, or gold (and their derivatives) was added to/used in their products. If so, they must conduct a reasonable country of origin inquiry (RCOI) to determine whether the mineral(s) used came from a conflict-free source (i.e. from outside the DRC region or from a conflict free smelter located in the DRC region). Affected companies must annually report the results of their RCOI to the SEC. Grid Connect is not an SEC registered company and is not required to file a report. Grid Connect supports the conflict minerals rules and requires all suppliers of any fabricated materials such as Printed Circuit Boards to be monitored. Grid Connect is committed to sourcing responsibly and considers mining activities that fuel conflict as unacceptable. Grid Connect’s efforts related to conflict minerals are aligned to the work

of the Electronic Industry Citizenship Coalition® (EICC®) and Global e-Sustainability Initiative (GeSI). The EICC’s and GeSI’s work includes the Conflict-Free Smelter Program and the Conflict Minerals Reporting Template. The Template provides a common industry approach for the collection of sourcing information related to conflict minerals. The template is available by contacting Grid Connect. 4.5 ISO 9000 ISO 9000 registration (or EN 29000 certification) is used widely in Europe on a voluntary basis as a condition of acceptance of a manufacturer's product or as a way of recognizing the manufacturer's credibility. While a quality system such as ISO 9000 indicates that a company has an efficient organization structure and has low failure costs, it does not always certify conformity with the CE marking directives. However, some directives require use of a quality management system as part of the conformity assessment. Grid Connect Inc. is committed to providing excellent products and services and creating a pleasant and stimulating working environment for its employees and those with whom it does business. The company recognizes that the disciplines of quality, health, safety and environmental management are an integral part of its management function. The company views these as a primary responsibility and believes that a key to good business is maintaining the appropriate quality standard, ISO 9001:2008. In pursuit of our policy we will: • Comply with all applicable statutory laws, statutory regulations and with the requirements of ISO 9001:2008. • Follow a concept of continual improvement and make best use of our management resources in all quality matters. • Communicate our quality objectives and our performance against these objectives throughout the company and to interested parties. • Take due care to ensure that activities are safe for employees, associates, subcontractors and others who come into contact with our workplace. • Work closely with our customers and suppliers to establish the highest quality standards and to ensure customer satisfaction. • Adopt a forward-looking view on future business decisions, which may have quality impacts. • Train our staff in the needs and responsibilities of quality management. • Recycle electronics, paper, plastics, metal, and glass through recycling facilities and donation centers.
