    External Interface Specification
                                          2016/6/13



Introduction
Model 420128RM Wireless Link Module is for the low latency wireless link between console and
bass box or rear surround speaker or both.
This document shows how to connect the wireless module.

Features and Functions
   •  2.4GHz, 5.2GHz, 5.8GHz, 5.2/5.8GHz dual band, 2.4/5.2/5.8GHz tri band
          o All band usage is under active software control according to each regional and
              country band plan assignments. Where the use of any band conflicts with local
              regulations, the radio will be locked out of that band.
   • 22Mbps data rate (15 MHz nominal channel bandwidth).
   • Modulation - QPSK
   • Antenna types –Inverted F with following gains:
                       2.4 GHz       5.2GHz        5.8GHz
     Antenna-A         1.98 dBi      4.18 dBi     4.98 dBi
     Antenna-B         2.2 dBi       5.02 dBi     5.56 dBi

   •   Target Power –
       Band (GHz)     Target Power
       2.4            3.08 dBm + 2dB
       5.2            8.83 dBm + 2dB
       5.8            9.31 dBm + 2dB

   •   One module design can be used for both source and sink
            o Source : Central Unit (CU)
            o Sink : Mobile Unit (MU)
   •   Bi-directional audio and data
   •   Up to four uncompressed stereo audio channels (max 7.1ch configuration)
   •   I2S for audio
            o Input (Source) : 44.1kHz, 48kHz
            o Output (Sink) : 48kHz
   •   I2C for control

        tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en
        compromettre le fonctionnement.


RF Exposure - Min. 20 cm separation distance required for this module.

2.4 GHz statement – The radio module only supports Channels 2412, 2438, 2464 MHz and does
not support Channel frequencies 2467 MHz or 2472 MHz.


5 GHz UNII statement – This module supports automatic discontinue transmission as described in
15.407(c):

“The device shall automatically discontinue transmission in case of either absence of information
to transmit or operational failure. These provisions are not intended to preclude the transmission
of control or signalling information or the use of repetitive codes used by certain digital
technologies to complete frame or burst intervals.”

        When the module is configured as a “Master” device, it will transmit digitally encoded
        audio data as fed from the host system via an I2C data bus. If this data is malformed as
        indicated by an incorrect data checksum. Transmission ceases. When configured as a
        “Slave” device, the only transmissions occur after the reception of a data packet from the
        Master. Lack proper data reception, a single transmission of “Not Acknowldge” to inform
        the master of the failure. Lacking pairing with a Master device, the module is in receive
        only mode.

Frequency stability 15.407(g).

“Manufacturers of U-NII devices are responsible for ensuring frequency stability such that an
emission is maintained within the band of operation under all conditions of normal operation as
specified in the users manual.”

        This is accomplished by through the use of a crystal controlled oscillator having a
        frequency tolerance of 20 parts per million in accuracy. This frequency is verified at
        manufacture to be within these tolerances.


Labeling - For a host manufacture’s using this certified modular, an additional permanent label
referring to the enclosed module: “Contains Transmitter Module FCC ID: A94410128RM and IC:
3232A-420128RM” or “Contains FCC ID: A94410128RM and IC: 3232A-420128RM” must be used.
The host OEM user manual must also contain clear instructions on how end users can find and/or
access the module and the FCC ID.
