RI-STU-MRD2

The RI-STU-MRD2 is a micro reader module with advanced features that is backward compatible with the RI-STU-MRD1 module. It features new protocols and commands to communicate with low frequency (LF) half duplex (HDX) and advanced transponders for programming and tuning after the production phase. The Microreader supports serial and USB data communications between a PC and transponders. The Microreader supports TTL data communications through its serial communications interface (SCI), which allows communication to a standard interface when using an additional communications driver (for example, RS232 or RS422). In addition, a USB interface is available and requires only a few external components. For easy access to the USB port from the PC side, the reader is managed as a COM port. The microreader can be controlled remotely either by providing certain inputs with the corresponding voltage level or by sending commands to the SCI or USB.
