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

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.

7 Guidelines for Efficient and Safe Use
7.1 General
Read this information before using your OWLAN211b module.
For any exceptions, due to national requirements or limitations, when using your
OWLAN211b 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 2.3.3 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.
7.3 Radio Frequency Exposure
The OWLAN211b module contains a small radio transmitter and receiver. During
communication with other WLAN products the OWLAN211b Module receives and transmits
radio frequency (RF) electromagnetic fields (microwaves) in the frequency range 2400 to
2500 MHz. The output power of the radio transmitter is very low.
When using the OWLAN211b 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 0.94 - 2006-09 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 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.

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?

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.

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.
