1 General Description

The OZMO2000WM014 Wireless Module is a fully assembled and tested generalpurpose module using the OZMO2000 wireless System-on-Chip (SoC). The module contains the OZMO2000 chip, memory, antenna, and all other necessary components to operate the OZMO2000.

The memory is preloaded with firmware that is compatible with Windows 7 SoftAP or WiFi 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.

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.

7.3 Terminal Characteristics

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 +5dBm (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: FCC & IC Radiation Exposure Statement:

Page 9 of 11

OZMO2000WM014 Module User Guide

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-B1”

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.

10.1 FCC ID
