Table 3-3 Audio/Visual Options Bits Decoding for IT2235 Tag
The IT2235 Tag produces two distinct and discernible audible signals. These signals
are in the form of high and low frequencies referred to as a beep (high frequency) HI,
or a buzz (low frequency) LO. These two different tones are used to generate the
various sequences as requested by the customer.
RF commands always have priority over the display of any LED, LCD, or audio tones.
ATA Tag
In ATA mode, the tags are read-only and do not use a reader-to-tag modulated signal.
When powered, and in the presence of an unmodulated signal, ATA tags always
attempt to backscatter.
Tag Programmer
Tag programmers are used to write data to and read data from tags that are used in an
RFID system.
