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 115H to 117H 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.
