Unsupported Features
• RF On-time
• Noise Floor
• Noise Floor with Transmit On
• Frequency
• Temperature
• Antenna Ports
• Current Protocol
Antenna Port
The ThingMagic Nano has one monostatic antenna port. This port is capable of both transmitting and
receiving. The module also supports Using a Multiplexer, allowing up to 4 total logical antenna ports,
controlled using two GPIO lines.
NOTE: The ThingMagic Nano does not support bistatic (separate transmit and receive port) operation,
even when configured to operate with a multiplexer.
Using a Multiplexer
Multiplexer switching is controlled using one or two of the General Purpose Input/Output (GPIO) lines. To
enable automatic multiplexer port switching the module must be configured to Use GPIO as Antenna
Switch in /reader/antenna/ portSwitchGpos.
Once the GPIO line(s) usage has been enabled the following control line states are applied when the
different Logical Antenna settings are used. The tables below show the mapping that results using GPIO 1
and 2 for multiplexer control (as is used by the ThingMagic 1 to 4 multiplexer) allowing for 4 logical antenna
ports.
