MOD-RFID125 is an RFID station, able to read Manchester-encoded 64-bit EM4102 tags with 64 periods of carrier frequency per data bit. All the complexities of RFID tag detection, verification and decoding are handled by MOD-RFID125. After it strips the header and the checksums, it reports the 40-bit ID of the transponder tag.
MOD-RFID125 has two modes of operation, easily switched by a single button press.
USB HID Mode: When the device is connected via USB to a host PC, it will represent itself as a USB HID keyboard. When an RFID transponder is detected in the vicinity, the module will type the HEX-representation of the transponder ID. Thus the ID is read by any application that accepts keyboard input, e.g. Notepad.
USB CDC Mode: In this mode, the device represents itself as a USB CDC virtual serial port. It provides a simple shell-like command-line interface for configuring and interacting with the module. The device echoes back the typed characters and waits for Carriage Return (Enter) before processing the line input. Any terminal software, e.g. HyperTerminal, can be used to open the COM port, assigned by the OS, and type in commands.
