Version 0.94 - 2006-09 18 2.4 Hardware Reset A hardware reset input is available on the J1 and J3 connectors (see section 2.1). An exter-nal reset source must be open drain or collector. The RESET pin is pulled-up internally with 56kΩ. See example in A.2.2 2.5 Power Control The CB-OWLAN211b module can be put in one of four power modes. • Active mode – no power saving is done. • Sleep mode – power saving. The module is held in low power mode and only listens and responds to beacons. • Powers save mode – Maximum power save. The device is incapable of transmitting or receiving data. • Reset mode – The RESET pin is held down. As long as the RESET pin is held low the internal power regulators are shut off. This will ensure maximum power save.
Version 0.94 - 2006-09 19 3 Antennas There are 2 different antenna options available: • An internal surface mounted (SMD) antenna. • An “external antenna” should be connected to a U.FL connector.

Version 0.94 - 2006-09 25 4.2 Using the J2/J3 Board-to-Board Connectors The board-to-board connector should be a 1mm pitch one-piece part connector. The rec-ommended 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 3.0mm and this has to be considered if components are to be mounted on the motherboard under the CB-OWLAN211b board. The connector is also avail-able with a height of 6.0mm and 10.0mm (The FSI-120 series 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 CB-OWLAN211b board directly into these inserts. If you want to have a tighter and more secure mounting you may use longer screws and se-cure 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.

Version 0.94 - 2006-09 27 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 6) and are manufactured by PEM Fastening Systems (www.pemnet.com), part no KFS2-M2 (see Figure 7). Be careful with the distance between the nuts regarding alignment. Figure 7: 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 (CB-OWLAN211bi) cannot be mounted in a metal enclo-sure. No metal casing or plastics using metal flakes should be used, avoid also metallic based paint or lacquer. Keep a minimum clearance of 10mm 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. See section 3.2 for more information on the antenna options available.

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 Power Supply The OWLAN211b module must be supplied by a limited power source according to EN 60950-1. • 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 0.94 - 2006-09 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 13: Step-by-step guide with Yes and No answers. Question Yes No Are you going to integrate the CB-OWLAN211b module in a metal enclosure? The internal antenna models cannot be used. Use the OWLAN 211bx. You are free to choose between the products. The internal antenna models are lower cost and are easier to design-in. How-ever, an external antenna could give better range. Do you wish to use SPI when com-municating with the CB-OWLAN211b Module? TBD TBD TBD TBD Are you using a 5V host system? The SPI interface is 5V tolerant TBD Is low power consumption important? The CB-OWLAN211b Module can be held in RESET mode to en-able maximum power saving. Do you want to manually reset the module?
Version 0.94 - 2006-09 36 A.2 Design Examples A.2.1 Basic Design Basic desing example. Note: The 10uF decoupling capacitor must be positioned close to the module power supply pins. This to compensate for the current peaks during power up and reset release. Figure 8: Basic design example.

Version 0.94 - 2006-09 37 A.2.2 Reset The RESET pin can be connected to an external reset source, see Figure 9 for a switch ex-ample. If the reset signal is connected to an output signal it must be an open drain or collector, see Figure 10. Figure 9: A reset switch. The RESET pin can be left unconnected if not used. Figure 10: Design of an open collector reset from an active high output. A.2.3 Bluetooth co-existence TBD
Version 0.94 - 2006-09 38 A.3 Test Points The firmware outputs diagnostic messages during runtime to aid driver development and for easier troubleshooting. The messages are output as serial data, TTL-level, at test point 4. See Figure 11 for localization of test points. Figure 11: Bottom View showing the location of test points. A RS232 level shifter needs to be used if the diagnostic messages shall be logged using a PC.

Version 0.94 - 2006-09 39 NOTE: The output format is not fixed and can therefore change without notice be-tween different versions of the firmware. The examples listed below are shown for an education purpose only. A.3.1.1 After Firmware Download After firmware download is completed the following output is given: The most important information, besides the fact that the firmware is actually loaded and run-ning, are the version number and the MAC address. The example above lists firmware version 6.35 and a MAC address of 00:12:F3:FF:FF:FD A.3.1.2 Scan Scan commands are, similar to other commands, prefixed with a ‘>’ to indicate start of com-mand, and a ‘<’ to indicate end of command.
