components to operate the OZMO2000.
The memory is preloaded with firmware that
is compatible with Windows 7 SoftAP or Wi-
Fi CERTIFIED™ Wi-Fi Direct host systems.
With modified firmware, the OZMO2000 can
support other interfaces, such as I2C and
GPIO. Contact your Ozmo FAE for
assistance with these interfaces.
For detailed information on the OZMO2000
component itself, refer to the OZMO2000
datasheet.
2 Features

5.2 Using the module
The WM014 module is designed to operate with customized embedded firmware programmed
into the module by Ozmo Devices which controls the functioning of the radio and the various
interfaces.
The General Purpose Input-Output pins (referred to as AIO or GPIO pins) are configured and
monitored by the firmware.
Depending on the programmed functionality, the module will send data over the wireless link
corresponding to the inputs received on the AIO pins, or will output digital signals from the AIO
pins based on data received over the wireless link.
Ozmo application engineers will work with customers to define the desired Input-Output behavior
and develop the customized firmware to achieve the desired digital input-output behavior. This
has no effect on the radio operation which is defined by low-level firmware and hardware and
always operates in accordance with FCC and Wi-Fi standards. The custom aspects of the
firmware only affect the formatting and timing of the back-end digital I/O functions.

7.4 Radio Characteristics
7.4.1 Radio Frequencies
This module operates on standard Wi-Fi channels within the 5.15GHz to 5.825GHz bands (limited
to 5180-5240MHz and 5745-5825MHz for operation in the US). Ozmo Devices will program the
module with firmware which automatically selects the channel according to the designated
application requirements established with the customer.
7.4.2 Transmitter
The WM014 module is designed to operate at firmware-controlled transmit power power levels.
The module has been FCC certified at the maximum transmit power settings of +5 dBm
(5.150GHz band) and +1 dBm (5.8GHz band). Firmware may be provided to customers which
configures the device at lower transmit power levels to achieve longer battery life, but it is not
possible to operate this module at any higher power levels than those used during the certification
testing.

7.5 ESD Caution Notice
ESD (Electrostatic Discharge) can damage this device. Ozmo, Inc. recommends that all
integrated circuits be handled and stored using appropriate ESD precautions. Failure to observe
proper procedures can cause ESD damage ranging from performance degradation to complete
device failure.
8 Module Floorplan
The diagram below shows the floorplan and dimensions of the OZMO2000WM014 Wireless
Module.
Figure 4 Floorplan of the OZMO2000WM014 Wireless Module
The WM014 module is designed to be mounted to the end-equipment printed circuit board (pcb)
either as a card inserted in a slot or laid flat and soldered as a surface mount component. In the
latter case standard surface-mount technology (SMT) circuit construction procedures should be
followed. For inserting in a slot the pcb is 0.045” thick so the slot should be sized accordingly.

10 Regulatory notes
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 by moving the end equipment.
- 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: To assure continued compliance, (example - use only shielded interface cables
when connecting to computer or peripheral devices). Any changes or modifications not expressly
approved by the party responsible for compliance could void the user's authority to operate this
equipment.
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.
IMPORTANT NOTE:

This equipment complies with FCC & IC radiation exposure limits set forth for an uncontrolled
environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter. This device is intended only for OEM integrators under the following conditions:
- The transmitter module may not be co-located with any other transmitter or antenna.
As long as the condition above is 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 cannot be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC & IC authorizations are no
longer considered valid and the FCC & IC IDs cannot 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 separate FCC & IC authorizations.
Indoor usage for 5.2GHz
Important note:
Section 15.407(e) of the FCC Rules states that 5.15 – 5.25 GHZ band UNII devices are restricted
to indoor operations.
If the device is configured for those frequencies, the usage of the device must be restricted to
indoor applications.
End Product Labeling
The final end product must be labeled in a visible area with the corresponding FCC ID number.
Similar to: “Contains Transmitter Module FCC ID: EFU-OZMO-WM014-A2”
Manual Information That Must be Included
The user’s manual for end users must include the following information in a prominent location.
Warning: modifications of the product not approved by the manufacturer can void the
user’s authority to operate the device
The end product using this module must be labeled with the FCC 2part statement
“This device complies with FCC 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.”
This statement can be placed in the user’s manual if the product is too small.
