DESCRIPTION
The Texas Instruments low-frequency (LF) reader module 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-RFM-003B radio frequency power (RFM) module is capable driving a variety of antennas with inductance
ranges from 115µH to 117µH including TI standard RI-ANT-P02A stick antenna.
The RI-RFM-007 is designed to be connected to control module RI-CTL-MB2A (RS232 interface) or
RI-CTL-MB6A (RS422/485 interface) which provides the interface to a host system, power supply connectors
and additional I/O’s. The RI-RFM-003B module in combination with a control module 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 Mini Radio Frequency Module is the interface between a 134.2 kHz HDX/FSK transponder and
the Data Processing Unit.
It sends an energizing signal to the transponder, modulates the RF signal to send data to the transponder,
receives the identification signal and processes it for digital decoding. The small size and low supply voltage
make the Mini RF Module well suited for portable read/ write units.
