RDR-485 forecourt RFID reader
RDR-485 RFID reader with RS-485 interface is intended for reading RFID contactless identifiers (cards, tags, bracelets, others) of EM-marine (EM-4100) and Mifare types (UltraLight, Mifare One S50, Mifare One S70, others) and sending it over RS-485 interface.
The reader control protocol is Modbus RTU.
RDR-485 reader provides reading of the identifier from distance from 50 to 80 mm (depending on the conditions). Reader allows to configure buzzer and 2 color LEDs for indication (green and red).

Configuration utility #
RDR-485 readers have a configuration utility running under Windows OS, which allows to configure:
- to configure reader’s communication address
- to configure reader’s communication parameters
- to search for the reader in case if you forgot its communication address and communication parameters
- to enable and disable automatic tag reading (in this case the reader automatically sends the ID of the tag read to the line, for this feature to work without collisions the reader should be only one on the line)
- to set indication of the reader by its LEDs and buzzer
