DESCRIPTION

The Texas Instruments’ low-frequency (LF) reader provides all the functionality required to communicate with

Texas Instruments 134.2 kHz LF transponders which are available in a variety of form factors. The RI-STU-251B

Reader/Writer is capable driving a variety of antennas with inductance ranges from 26.0µH to 27.9µH including

TI standard antennas RI-ANT-G01E, RI-ANT-G02E, RI-ANT-G04E gate antennas as well as RI-ANT-S01C and

RI-ANT-S02C stick antennas. The RI-STU-251B includes an automatic antenna resonance tuning feature which

further reduces the need for maintenance and simplifies installation. It also supports both RS232 and RS422/485

interface standards.

The RI-STU-251B is well suited for usage in a broad range of applications including, but not limited to, access

control, vehicle identification, container tracking, asset management and waste management applications.

The Series 2000 Reader S251B provides all RF and Control Functions to communicate with 134.2 kHz

HDX/FSK transponders. It sends an energizing signal to the transponder, modulates the RF signal to send data

to the transponder, decodes and checks the received transponder data and transmits it via a standard serial

interface (RS232, RS422/485). The reader includes a Dynamic Auto Tuning (DAT) function that automatically

tunes a standard antenna to resonance and keeps it tuned during operation.
