RI-STU-251B-30 is a low-frequency (LF) reader provides all the functionality required to communicate with TI 134.2kHz LF transponders. 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 such as gate antennas, 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 Series 2000 Reader S251B provides all RF and Control Functions to communicate with 134.2kHz 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. The reader includes Dynamic Auto Tuning (DAT) function that automatically tunes a standard antenna to resonance and keeps it tuned during operation.
