Meaning
With RFID readers, the number of transponders in the
antenna field is indicated. UIN0 ... UIN3 can be interpret-
ed as binary values.
Example:
UIN3 = 0; UIN2 = 0; UIN1 = 1; UIN0 = 1
⇒ 3 transponders
With optical reader devices, the various states of the
reader are displayed.
• UIN0: Corresponds to "IN_OP" bit of the reader
• UIN1: Corresponds to "RDY" bit of the reader
• UIN2 + UIN3: These two bits are interpreted as an
unsigned value (bit 2 is the less significant bit) that
represents the number of available decoded codes. If
the value = 3, three or more decoded codes are avail-
able.
Number of data elements received after successful exe-
cution of the command.
