Antenna Ports

38 Functionality of the Embedded Modules

Output lines. In order to enable automatic multiplexer port switching the module must be

configured to use Use GPIO as Antenna Switch in S

et Reader Configuration(9Ah).

Once the GPIO line usage has been enabled the following control line states are applied

when the different Logical Antenna settings are used in S

et Antenna Port (91h).

Note

The TX/RX Logical Antenna values are static labels indicating the available

control line states. The specific physical antenna port they map to depends

on the control line to antenna port map of the multiplexer in use. The

translation from TX/RX Logical Antenna label to physical port must be

maintained by the control software.
