FCC ID: 2ATDA-WMODLP6 Radio Module for Audio and Data

Document Title SOP-23-2:

Wireless Module Manual REPORT Report No. 1. PURPOSE The WMODLP is a direct sequence spread spectrum transceiver module designed to be used in the 2.4 GHz ISM band. This module is for internal use only and is not sold as a device on the market. The WMODLP module is integrated into the Audio Pathway System by Innovere. 2. REGULATORY INFORMATION The integrator is responsible for testing their end-product for any additional compliance requirements with this module installed. Published FCC Module integration and RF Exposure guidance as well as label requirements should be followed in the end product. As the module does not have a RF Shield, Spurious radiated emission should be evaluated per Module integration guidance. The end product with this module may be subject to some other form of authorization or testing requirements, e.g. FCC part 15 and ICES-003 unintentional emission test requirement. It is the integrators responsibility to comply with all applicable rules and be properly authorized. Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. 2.1. Regulatory labelling The radio module will be labelled with the following information:

Each channel has a bandwidth of 4 MHz. 4. HARDWARE DESCRIPTION The Innovere wireless module is a small PCB with a wireless audio chip (CC8530), an RF amplifier

(CC2592), an F-type trace antenna, and a U.FL antenna connector. The antenna can be selected by populating a jumper resistor. The module is powered by an on-board voltage regulator and connects to its host using a 14-pin mezzanine connector. Clocking is done by means of a 48 MHz crystal oscillator. Figure 1 shows the pinout of the mezzanine connector. It contains pins for power, an SPI control interface, and an I2S digital audio interface. Figure 2 shows the orientation of the mezzanine connector on the bottom of the wireless module. Figure 1. Mezzanine connector pinout Figure 2.

PROGRAMMING The Purepath Wireless Configurator software is used to generate and load the wireless module configuration files used in the Innovere system. For regulatory testing, the module can be loaded with various regulatory test images using the Purepath Wireless Commander software. The wireless module is programmed by using a Purepath Wireless Audio EB evaluation board and a CC debugger. 6. SOFTWARE CONTROL The CC8530 on the Innovere Wireless Module is configured in host control mode. In this mode, the device needs to be controlled by a host microcontroller using an SPI interface. The CC85xx Family User Guide describes the commands that are used to control the wireless module, as well as the method of sending the command packets over the SPI interface. 7. PAIRING PROCEDURE The pairing feature of the wireless modules allows the components of the Innovere system to be modular, meaning that any individual component of the wireless pathway can be swapped out in the field without having to reprogram or reconfigure it. Each wireless module is identified using two different names. The device ID is a 32-bit value that is hardcoded and unique for every CC8530 device. The product ID is a 32-bit value that is written into the flash memory of the CC8530 chip and is different for each individual component in the wireless pathway of the Innovere system. Every slave component of the wireless audio pathway has been configured to only recognize masters with a specific product ID depending on the component. When the slave module is started up in pairing mode, it will scan for a network broadcast by a master module with the correct product ID. Upon finding a suitable master, the slave will attempt to connect to it, and upon a successful connection will store its unique device ID in its internal memory. When the slave module is started up in its regular connection mode, it will scan for and connect to the master whose unique device ID is stored in its internal memory. 8. DATA SIDE CHANNEL The data side channel (DSC) is a stream of user-specified data that is sent alongside the audio data stream in the wireless pathway. This data channel is bidirectional and can used to send packets of generic data bytes. In the Innovere system, DSC packets are currently only sent upstream (from the slave to the master) and is used to communicate connection status and battery level. When connected to a master, the slave module will periodically feed data upstream to the master. Likewise, the master is set to periodically poll its DSC buffer for data received from the slave. 9.
