Functionality of the ThingMagic Nano 73
Protocol Support
Unlike the M6e and Micro modules, the ThingMagic Nano does not have the ability to
support tag protocols other then ISO 18000-6B (gen2). Future support for ISO 18000-63
(Gen2V2) is likely, however.
ISO 18000-6C (Gen2)
Gen2 Protocol Configuration Options
The ThingMagic Nano supports limited ISO-18000-6C profiles, with only the Backscatter
Link Frequency (BLF) and “M” value as configurable options. The protocol options are set
in the MercuryAPI Reader Configuration Parameters (/reader/gen2/*). The following table
shows the supported combinations:
Note
It is important that the /reader/baudRate is greater than the BLF divided
by the “M” value when reading continuously. If it’s not then the reader could
be reading data faster than the transport can process it, and the reader’s
buffer might fill up.
