The MXi board has a BDM (Background Debug Mode) connector that allows an external computer or laptop to
download the software program into the CPU chip. The CPU chip holds the program in its internal Flash memory
and so there is no external chip or device that need be replaced to change/upgrade the software.
The concept of this design places all of the control and monitoring functions in one place and therefore eases the
setup and maintenance functions on this series of transmitters.
