Golden Power Manufacturing Ltd. RTWG-01 WIFI Module
FCC: QO8-WIFIG0325
IC: 4714A-WIFIG0325
The module is intended to be embedded in a variety of devices allowing the application
device to communicate via WIFI and the internet if the local WIFI is so connected. The
module will be certified as a stand-alone module and does not require any particular
housing. There is a standard plastic housing that the module may or may not be enclosed
in from the factory. This housing is not part of the module from a certification point of
view but does serve as a useful form factor and conforms to an emerging adhoc standard
called USNAP.
The regulatory agency labels come with the module but are not affixed at the factory. If
the module is intended to be used as a USNAP the label should be affixed to the plastic
housing as shown in the figure
below.
Per FCC Part 15.19:
When the device is so small or for
such use that it is not practicable to
place the statement specified under
paragraph (a) of this section on it, the
information required by this paragraph
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 identifier or the unique identifier,
as appropriate, must be displayed
on the device.
Thus:
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.
Sec. 15.21 Information to user.
The users manual or instruction manual for an intentional or
unintentional radiator shall caution the user that changes or
modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. In
cases where the manual is provided only in a form other than paper,
such
as on a computer disk or over the Internet, the information required by
this section may be included in the manual in that alternative form,
provided the user can reasonably be expected to have the capability to
access information in that form.
Thus:
The user is cautioned that changes or modifications not
expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
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.
If the module is intended to be embedded in another enclosure the label should be affixed
to the non-component side of the module PC board prior to assembly in the final location.
The module is not intended to be used in a device which comes in close proximity (closer
than several feet) to a person for any appreciable length of time.
The module should be situated such that the antenna has a clear and unobstructed path to
other WIFI devices i.e. APs.
The module may be equipped with a USB connector for provisioning purposes. If so, the
user can use a Micro-USB cable between their PC and the module. The module should
not be in it’s native application position when this process is under way. During this
process the module is powered by the USB cable.
The module can be provisioned using the method outlined above but can also be
provisioned using other standard methods i.e. adhoc connection to another WIFI enabled
device or by WPS. In these cases the module is installed in the application device and
does not use the USB method.
The module has a 10 pin connector conforming to the USNAP standard with the
following functions:

Signal Ground establishes a common ground potential
+3.3V Provides power for Radio use. Radio is limited to 200mA peak.
MOSI Carries Application device SPI data to Radio Module
MISO Returns Radio SPI data to Application Device,
High Z when SELECT* is high.
SCLK Provided by the Application Device
SELECT* Provided by the Application Device. Low during each byte of SPI data Transfer.
Normally high. Application Device can assert (low) to request data transfer with radio.
ATTENTION* Radio can use this signal to alert the Application device that it needs service
Low Signal from Radio Requesting an SPI data transfer
RESET* Application can use this signal to return the radio to a known start up state
Low Signal from Thermostat negated after poweron. Open collector/drain output.
