2.4 Hardware Reset
A hardware reset input is available on the J1 and J3 connectors (see section 2.1). An external 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.

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 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 3.0mm and this has to be considered if components are to be
mounted on the motherboard under the CB-OWLAN211b board. The connector is also available 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 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.

order number and refer to the connectBlue global quote number for best price. For technical
questions regarding the Samtec connectors please contact connectBlue or Samtec at
(Scandinavia@samtec.com).
See Figure 6 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.

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 enclosure.
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.

For an end product using the product cB-0904-02 there must be a label containing, at least,
the following information:
This device contains
FCC ID: PVH090402
IC: 5325A-090402
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.
Where the module will be installed in final products larger than 8 cm x 10 cm following
statement has to be placed ONTO 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.”
In case, where the final product will be installed in locations where the end-consumer 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.
6.3.1.4 RF-exposure Statement for cB-0904-02
This modular transmitter MUST have a separation distance of at least 2.5 cm between the
antenna and the body of the user or nearby persons, excluding hands, wrists, feet, and ankles.
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 2.5 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.

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

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.
