An external reset source must be open drain or collector. The RESETn pin is pulled-up internally with 56 k. In order to improve the ESD performance the RESETn pin should be decoupled by a 10 nF capacitor to VSS. See example in A.2.2 2.5 Power Control The OWLAN211g module can be operated in four different power modes. * Idle Active Mode - The module is not associated with a WLAN-node, transmitting and receiving of data does not occur. * Associated Active Mode - The module is associated with a WLAN-node, The power consumption depends on the data rate. * Associated Sleep Mode - The module is associated with a WLAN-node but is most of the time kept in sleep mode. At regular intervals it wakes up and it listens and responds to beacons. * Deep Sleep Mode - Maximum power save. The device is incapable of transmitting or receiving data. Version 1.14 - 2009-12 16 3 Antenna Information There are 2 different antenna options available: * An internal surface mounted (SMD) antenna. * Two U.FL connectors for external antenna.

The reasons for the 2.3mm holes are that the threaded M2 holes on the single and double row connectors (see section 4.2.1) are not aligned. The outer tangents of the 2.3mm holes align the module if the single row connectors are used and the inner if double row connectors are used (see Figure 11). Choose the outer tangent (CC distance 27.24mm) if the module is aligned and mounted with some other technique based on M2 screws (e.g. press-fit nuts), see Figure 12. Figure 11 The 2.3 mm mounting holes Version 1.14 - 2009-12 26 4.2 Using the J2/J3 Board-to-Board Connectors The board-to-board connector should be a 1 mm pitch one-piece part connector. The recommended manufacture is Samtec with many connector options available; see section 4.2.1.1. Chapter 2 contains more information about the connector and the electrical interface. 4.2.1 Suitable One-Piece Part Connectors 4.2.1.1 Double row ASP-118580-01 / ASP-118581-01 Connectors This connector is a double row connector and connects both J2 and J3. This connector has a height of 3.0 mm and this has to be considered if components are to be mounted on the motherboard under the OWLAN211g board. The connector is also available with a height of 6.0 mm and 10.0 mm (The FSI-120 serie from Samtec). There are alignment pins on the bottom side of the connector. The connector is available with M2 threaded inserts ASP-118580-01) that fit the mounting holes on the board. You may screw the OWLAN211g board directly into these inserts. If you want to have a tighter and more secure mounting you may use longer screws and secure it using a nut on the backside of the motherboard. Another way to mount the module is to use press-fit nuts on the motherboard and skip the M2 threads on the connector (ASP-118581-01), see section 4.3 for more information about press-fit nuts.

For technical questions regarding the Samtec connectors please contact connectBlue or Samtec at (Scandinavia@samtec.com). See Figure 12 for more information about the connector and necessary measurements on the motherboard. The large mounting holes on the motherboard are designed for press-fit nuts and could be smaller if press-fit nuts are not used. Version 1.14 - 2009-12 27 Figure 12: Host PCB layout [mm] for double row connector. 4.3 Using Press-Fit Nuts for Mounting the Module A press-fit nut is pressed into the PCB from the bottom side with a special press tool. M2 sized press-fit nuts are suitable for the modules (see Figure 12) and are manufactured by PEM Fastening Systems (www.pemnet.com), part no KFS2-M2 (see Figure 13). Be careful with the distance between the nuts regarding alignment. Figure 13: KFS2-M2 press-fit nut. Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used. 4.4 Antenna Issues The unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna (OWLAN211gi) cannot be mounted in a metal enclosure. No metal casing or plastics using metal flakes should be used, avoid also metallic based paint or lacquer. Keep a minimum clearance of 10 mm between the antenna and the casing. Keep 10 mm free space from metal around the antenna. If a metal enclosure is required, one of the external antenna options has to be used.

More information at: http://europa.eu.int/comm/enterprise/rtte/gener.htm Version 1.14 - 2009-12 30 6.2 IC and FCC Compliance for OWLAN211g See Table 1 for information about the different product variants. 6.2.1 IC Compliance Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This device has been designed to operate with an antenna having a maximum gain of +8.5 dBi. Having a higher gain is strictly prohibited per regulations of Industry Canada. The required antenna impedance is 50 ohms. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropic radiated power (EIRP) is not more than that required for successful communication. The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada's website www.hc-sc.gc.ca/rpb. 6.2.2 FCC Statement for OWLAN211g 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 received, including interference that may cause undesired operation. NOTE: 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 interference by one or more 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 6.2.3 Antenna Our module type OWLAN211g is for OEM integrations only. In the end-user product the module shall be professionally installed in such a manner that only the authorized antennas can be used. Version 1.14 - 2009-12 31 6.2.4 Caution Any changes or modifications NOT explicitly APPROVED by connectBlue AB could cause the module to cease to comply with FCC rules part 15, and thus void the user's authority to operate the equipment. 6.2.4.1 Ad-hoc mode frequencies Our module type OWLAN211g when operating under the definition of a client in 47 CFR 15.202 is preconfigured to use the most restrictive regulatory domain. For this reason the available operating frequency range is limited to channel 1 - 11 (2412 - 2462 MHz). If the regulatory domain of the module for any reason is changed it may cause operation on illegal frequencies and as a result the module will cease to comply with FCC rules part 15, and thus void the user's authority to operate the equipment. 6.2.5 Labeling Requirements for End Product For an end product using the product OWLAN211g there MUST be a label containing, at least, the following information: This device contains FCC ID: PVH090901 IC: 5325A-090901 The label must be affixed on an exterior surface of the end product such that it will be visible upon inspection in compliance with the modular approval guidelines developed by the FCC. In accordance with 47 CFR 15.19 the end product shall bear the following statement in a conspicuous location on the device: "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 received, including interference that may cause undesired operation." When the device is so small or for such use that it is not practicable to place the statement above on it, the information shall be placed in a prominent location in the instruction manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed. However, the FCC ID label must be displayed on the device. In case, where the final product will be installed in locations where the end-user is not able to see the FCC ID and/or this statement, the FCC ID and the statement shall also be included in the end-product manual. 6.2.6 RF-exposure Statement for OWLAN211g This modular transmitter MUST have a separation distance of at least 20 cm between the antenna and the body of the user or nearby persons. If the radio module is installed in a laptop display, transmission MUST be prevented if the lid is closed to ensure that the minimum distance of 20 cm between the user and the transmitting antenna is maintained. Any notification to the end user of installation or removal instructions about the integrated radio module is NOT allowed.

Version 1.14 - 2009-12 33 7 Guidelines for Efficient and Safe Use 7.1 General Read this information before using your OWLAN211g module. For any exceptions, due to national requirements or limitations, when using your OWLAN211g module, please contact connectBlue AB. Note: Changes or modifications to the product not expressly approved by connectBlue AB will void the user's authority to operate the equipment. 7.2 Product Care * Do not expose your product to liquid or moisture. * Do not expose you product to extreme hot or cold temperature (see Section 2.2.3 for further information) * Do not expose your product to lit candles, cigarettes, cigars, open flames, etc. * Do not drop, throw or try to bend your product since rough treatment could damage your product. * Do not attempt to disassemble your product. Doing so will void warranty. The product does not contain consumer serviceable or replaceable components. Service should only be performed by connectBlue AB. * Do not paint your product as the paint could prevent normal use. * If you will not be using your product for a while, store it in a place that is dry, free from damp, dust and extreme heat and cold. * The clearance and creepage distances required by the end product must be withheld when the module is installed. * The cooling of the end product shall not negatively be influenced by the installation of the module when the module is installed. 7.3 Radio Frequency Exposure The OWLAN211g module contains a small radio transmitter and receiver. During communication with other WLAN products the OWLAN211g module receives and transmits radio frequency (RF) electromagnetic fields (microwaves) in the frequency range 2400 to 2480 MHz. The output power of the radio transmitter is very low. When using the OWLAN211g module, you will be exposed to some of the transmitted RF energy. This exposure is well below the prescribed limits in all national and international RF safety standards and regulations. Version 1.14 - 2009-12 34 7.4 Electronic Equipment Most modern electronic equipment, for example, in hospitals and cars, is shielded from RF energy. However, certain electronic equipment is not. Therefore: Note: This equipment emits RF energy in the ISM (Industrial, Scientific, Medical) band. Please insure that all medical devices used in proximity to this device meet appropriate susceptibility specifications for this type of RF energy. 7.5 Potentially Explosive Atmospheres Turn off your electronic device before entering an area with potentially explosive atmosphere. It is rare, but your electronic device could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fuelling areas, such as petrol station, below deck on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders. 7.6 Safety Compliance In order to fulfill the safety standard EN 60950-1:2001 the OWLAN211g must be supplied by a Class-2 Limited Power Source. 7.6.1 Power Supply * Connect your power supply only to designated power-sources as marked on the product. * Make sure all cords and cable are positioned so that they will not be stepped on, tripped over or otherwise subject to damage or stress. * To reduce risk of electric shock, unplug the unit from any power source before attempting to clean it. Version 1.14 - 2009-12 35 Appendix A - Application Notes Usually only a subset of the available functionality is of interest to the designer. In addition, depending on the host system, the electrical interface can be designed in many ways. The designer can use the step-by-step guide in this chapter as an aid in the design process. A.1 Step-by-Step Guide Table 14: Step-by-step guide with Yes and No answers. Question Yes No Are you going to integrate the OWLAN211g module in a metal enclosure? The internal antenna models cannot be used. Use the OWLAN 211gx. You are free to choose between the products. The internal antenna models are lower cost and are easier to design-in. However, an external antenna could give better range. Do you wish to use SPI when communicating with the OWLAN211g module? Use the OWLAN211gi/x-02 or 04 Are you using a 5 V host system? The SPI interface is 5 V tolerant Version 1.14 - 2009-12 36 A.2 Design Examples A.2.1 Basic Design Basic desing example showing how to connect an OWLAN211gi/x (SPI bus) to a microcontroller. Note: The 22 uF decoupling capacitor should be positioned close to the module power supply pins. This to compensate for the surge current during power up and release of reset.

Version 1.14 - 2009-12 37 A.2.2 Reset The RESETn-pin is active low and can be connected to an external reset source, see Figure 15 for an example using a switch. If the RESETn-pin is to be controlled by an external signal this signal must be of open drain type. If the reset is controlled by a BI-state output (e.g. CMOS, totem-pole) care must be taken to ensure that current is not sourced into the RESETn-pin, see Figure 16 and Figure 17. Failing to do so may cause undesired operation of the module. OWLAN211g RESET Figure 15: Connecting an external reset switch to the RESETn-pin.
