Antenna Ports
Functionality of the Embedded Modules 39
Note
Just as under non-Multiplexing operation, Physical Module Port #1 must be
used for transmitting and Port #2 for receiving when configured for bistatic
operation.
If only one GPIO Output line is used for antenna control, the combinations of the available
output control line states (the GPIO line in use and the module port) result in a subset of
TX/RX logical antenna settings which can be used:
ONLY GPIO 1 Used for Antenna Switching
ONLY GPIO 2 Used for Antenna Switching
TX/RX Logical
