Dynamic-Link Library Executable routines that are stored as separate files with DLL extensions
and executed only when needed by the program.
Host Port Interface Interface used to access the DSP memory.
IEC Connector Three-pin connector used on sockets that carry mains electricity to the computer.
All PCs use a male IEC connector and mains lead with a female IEC connector.
Interrogation Pulse A signal transmitted by the coupler to activate the TAGSYS RFID tag’s
transponder.
Monitoring Port Parallel Port granting access to the HPI. It communicates directly with the Radio
Processing Unit
Multi-Read See Anti-Collision
Nibble Half a byte (4 bits)
Packaged Reader A reader in its casing.
Phase Shift Difference of phase between the 13.56 MHz field emitted by two antennas. This
feature is dedicated to rotating field applications and three-dimensional volume TAGSYS RFID tag
detection.
Protocol A set of rules governing a particular function, such as the flow of data/information in a
communication system (communication between a TAGSYS RFID tag and a reader or a reader
and a PC or host computer).
Radio Frequency Identification System (RFID) An automatic identification and data capture
system comprising one or more readers and one or more TAGSYS RFID tags in which data
transfer is achieved by means of suitable modulated inductive or radiating electromagnetic carriers.
Radio Processing Unit This unit controls the main features of the Medio L200, such as the RF
channels, the multiplexer and the TAGSYS RFID tag decoding.
Reader Electronic system for the communication between TAGSYS RFID tags and host
computers.
Reader Talks First Chip protocol for exchanges between the reader and the chip, whereby the
chip waits for a command from the reader to which it responds.
RS-232 Electronic Industries Association (EIA) standard for serial interfaces between computers
and peripherals that define the function, the electrical characteristics and the timing of signals.
RS-485 Electronic Industries Association (EIA) standard for multipoint, differential data
transmission. It allows multiple nodes to communicate bi-directionally over 1 or 2 twisted pairs.
TAGSYS RFID tag Small, flexible, injectable tag from the 13.56 MHz TAGSYS product line. A
TAGSYS RFID tag is made of a chip connected to an etched antenna.
Tag See TAGSYS RFID tag.
Tag Talks First Chip protocol for exchanges between the reader and the chip, whereby the tag
sends information continuously, without waiting for a specific command from the reader.
Transceiver A combined transmitter and receiver.
Transponder A combined receiver/transmitter that automatically transmits a signal when a ‘trigger’
is received by it. The trigger is often a pulse, called an interrogation pulse.
