Logical Port Configuration
The reason for numbering the logical ports in this way was so that “logical port 1” would
stay associated with physical port 1 on the module whether there was a multiplexer
connected to it or not and, similarly, “logical port 2” would stay associated with physical
port 2 whether there was a multiplexer connected to it or not. If the application calls for a
mixture of manual control of the multiplexer (via physical port selection and GPIO Output
line manipulation) and automatic control (by configuring a search list of logical antennas),
the benefits of this numbering system will be more clear.
The resulting full control map with physical and logical port numbering is:
