2 Scope
This manual is a reference to handle the WLAN part of the AGCO WLAN / Bluetooth
– Module and getting started with it.
2.1 Limitations
As the AGCO WLAN / Bluetooth Module is delivered fully assembled, we can only
give a limited handling manual.
This module may only operate with the assembled antenna and antenna connector.
There is no guarantee for proper operation with different antenna and antenna
connectors.
Further, all software-issues are done by the customer itself; MSC does only have a
limited description of the software-handling of this module.

4 Software
4.1
Linux driver WLAN
The WLAN chip of the AGCO WLAN / Bluetooth – Module, AW-GH321, is controlled
by the following linux-drivers:
- libertas
- libertas_spi
When the driver detects the WLAN chip, first the firmware must be uploaded. The
current version of firmware is fw 9.70.3p37. The corresponding files (spi8686.bin and
spi8686_helper.bin) must be situated in the filesystem in /lib/firmware/libertas.
When set up, linux will bring up an eth-device. Now the standard-linux items can be
used for communications.
4.2
Linux driver Bluetooth
The Bluetooth-Chip of the AGO WLAN / Bluetooth Module, Bluemod B20, ist
controlled by the following linux-drivers:
- standard USB driver
- NXP-ISP1760 driver (USB hub)
- Generic Bluetooth USB driver ver 0.4
The device is enumerated by the standard- and ISP1760-USB drivers. All following
accesses to this chip are done with standard-linux-tools for USB (e.g. hcitool) via the
Generic Bluetooth USB driver ver 0.4.
5 Housing
Guidelines
The individual case must be checked to decide whether a specific housing is suitable
for the use of the dedicated antenna. A plastic housing must at least fulfill the
following requirements:
· Non-conductive material, non-RF-blocking plastics
· No metallic coating
· ABS is suggested

6 Power
supply
The module requires a power supply with following characteristics:
3,3V ±0,1V low noise (
≤
10mV)
Due to the technological requirements and the pulsed radio transmission the supply
needs to be fed by an ultra fast (response time 20
μ
s) linear regulator.
NOTE: You must ensure that during operation the supply voltage never drops below
3.0 V. Otherwise the flash contents (firmware and/or configuration data) can get lost.

Federal Communication Commission Interference Statement
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 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.
FCC Caution:
Any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate this
equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is
firmware-limited to channels 1 through 11.

This device is intended only for OEM integrators under the following
conditions:
1) The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2) The transmitter module may not be co-located with any other transmitter
or antenna (except Bluetooth module B2029 FCC ID: YM6-B2029),
3) For all products market in US, OEM has to limit the operation channels in
CH1 to CH11 for 2.4G band by supplied firmware programming tool. OEM shall
not supply any tool or info to the end-user regarding to Regulatory Domain
change.
As long as 3 conditions above are met, further transmitter test will not be
required. However, the OEM integrator is still responsible for testing their
end-product for any additional compliance requirements required with this
module installed (for example, digital device emissions, PC peripheral
requirements, etc.).
IMPORTANT NOTE:
In the event that these conditions can not be met (for
example certain laptop configurations or co-location with another transmitter),
then the FCC authorization is no longer considered valid and the FCC ID can
not be used on the final product. In these circumstances, the OEM integrator
will be responsible for re-evaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna
may be installed such that 20 cm may be maintained between the antenna and
users. The final end product must be labelled in a visible area with the following:
- “Contains TX FCC ID: YM6-AWGH321 and FCC ID: YM6-B2029”
or
- “Contains TX FCC ID: YM6-AWGH321
Contains TX FCC ID: YM6-B2029”
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the
end product which integrates this module.
The end user manual shall include all required regulatory information/warning as
show in this manual.
