Get Application Commands
170 Command Set
Get Hardware Version (10h)
The Get Hardware Version command is used to get information about the module it is
executed on. Most of the information is not currently user-relevant but will often be
required by ThingMagic Support to help diagnose problems.
Get Hardware Version Fields
The format of this command is:
Note
On many earlier hardware revisions a status code of 0x0109
(FAULT_UNIMPLEMENTED_FEATURE) will be returned. This indicates the
necessary information for this command was not stored on the module at
that time. It is not cause for concern.
Get Antenna Configuration (61h)
The Get Antenna Configuration command returns the current antenna configuration
including which antennas are set to transmit and receive, and which ports have antennas
attached.
Reliable antenna detection requires that an attached antenna pass at least a small
amount of DC current. Many antennas do not pass DC current. Due to such antennas an
indication that a port is terminated is always accurate, but an indication that a port is not
terminated may not be accurate.
