Configuring the Coding Modules of a MIMO System

Complete the following steps to continue configuring the modules if you chose to add the
coding option for a MIMO mmWave Transceiver System.
Note
Before connecting the modules for the coding option, ensure that the modules
have been properly connected for standard use.
