2.3.14 Get System Information (Command Code 0x2B)
The Get System Information Command is an optional command that retrieves the system information
values from the VICC information fields. This command can be sent as addressed or unaddressed
request. These fields are summary of what is and is not supported on the tag, what the user memory size
of the VICC is, and if there is an IC reference field. The IC reference field is defined by the VICC IC
manufacturer.
To perform Get System Information using the GUI:
1. Select the radio button for Get System Info.
2. Select Tag Flags accordingly (see Figure 18 for one example).
3. Click Set Protocol.
4. Place tags or transponders near enough to the TRF7970A EVM antenna to be read.
5. Click Execute.
