1. INTRODUCTION
AWID's Sentinel-Sense MPR-2010AN
Ver. 1.21N is a long-range (12 to 15 feet) reader
with TCP/IP interface and general purpose digital I/O (GP I/O - four (4) input four (4)
outputs) that works with most leading passive UHF passive tags. This reader comes with
a unique combination of long read range, small size, and low power consumption. MPR-
2010 has an internal power converter, allowing it to work with a wide range of supply
inputs without affecting its performance. Its primary applications are asset management
and tracking, and fleet management applications.
The MPR-2010 reader is delivered with the following components and accessories:
• MPR reader – MPR-2010AN or
MPR-2010BN, Firmware Ver. 1.21N
• Optional where PoE switch or router is not available:
o Power supply – PS48-03A-SW, 50-60 Hz and 110 to 220 VAC.
o
Power Injector – PI-2000
o RJ-45 Cable
In order to control the MPR reader you will need the following:
• PC running Windows 98 or higher, CD-ROM drive Network connection
• Host software (AWID’s demo software or your own custom software).
• RFID Tags (EPC Class 0, 1, ISO Type B or EM Micro)
1.1. GENERAL DESCRIPTION & THEORY OF OPERATION
This Radio Frequency Identification (RFID) reader uses radio frequency to identify,
locate and track pallets and/or items that carry the appropriate RFID transponders.
MPR-2010 readers work in non-line-of-sight situations and in darkness, bright sun-light,
or through dirt, grime and smudges.
A typical RFID system consists of three components – a reader (interrogator), a
transponder (card or tag), and a data processing controller. MPR-2010 has an internal
micro-controller section, a transmitter section, a receiver section, and a circular polarized
transmit/receive antenna. Passive transponders (tags or labels) consist of an antenna
and an RFID ASIC (Application Specific Integrated Circuits). During operation, the
transmitter sends out an electromagnetic wave to establish a zone of surveillance. When
a transponder enters this zone, the electromagnetic energy from the reader begins to
energize the IC in the transponder. Once the IC is energized, it goes through an
initialization process and is ready to accept further commands. Upon receiving a
command that queries its identity, the RFID ASIC begins to broadcast its identity through
a low-energy back-scattering process, which selectively reflects or “back-scatters” the
electromagnetic energy back to the interrogator. The receiving circuits in the reader
sense and decode this “back-scattered” signal and determine the identity of the
transponder.
