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.

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.
