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.

AWID PROPRIETARY
Passive tags are “beam powered”, which is the electromagnetic energy radiated by the
transmitter section of the reader. Upon receiving a legitimated command, the tags will
cause the matching of the tags antenna to vary from match to mismatch, thereby causing
the tags to either absorb the RF energy or to reflect the RF energy. This absorption or
reflection sequence is commanded by the tag’s internal memory and this is how the tag’s
internal data are “conveyed” to the reader. The reader in turn monitors the perturbation of
the RF energy field, and thereby receives the varying degree of signal reflected from the
tag.
One of the unique design features for an RFID reader is that it must simultaneously
transmit a strong CW signal, while at the same time, receives a weak reflected signal
with little frequency separation. In a traditional design, such functions are implemented
through the use of a circulator. As shown in Figure 1, there is a 3-port device between
the Coupler and the band pass filter, which is called a circulator. A circulator is physically
constructed by a permanent magnet, a Y junction on a high-dielectric ferromagnetic
substrate, and a ferromagnetic enclosure to complete the flux field. A circulator permits
flow of RF energy in one direction only, e.g. from port 1 to 2, 2 to 3, and 3 to 1. When
one of the ports is terminated (matched condition), the other two are isolated in the
reverse direction. Many fixed-site RFID readers use circulators to ensure that the power
amplifier output flows from the amplifier (port 1) to the antenna (port 2), and the received
signal flows from the antenna (port 2) to the receiver (port 3). When properly matched, a
circulator can provide typically 15 to 18 dB of isolation between the power amplifier
output (port 1) and the receiver input (port 3), thereby reducing any in-band interference
from transmitter output to receiver input. MPR-2010 uses a similar circuit to accomplish
the same function, but in a much smaller physical size.
It should be noted that some fixed-site reader designs use separate transmit and receive
antennas to resolve this T/R signal isolation problem. Figure 2 is a block diagram of a
dual-antenna RFID reader. On the surface, this design has the advantage of allowing a
low-level design on the receive chain, which means lower compression point for mixers,
lower saturation point for amplifiers, and the possibility of using a front-end amplifier to
enhance receiver sensitivity. Such dual-antenna design becomes problematic in a mobile
environment, where signal strength is not easily controlled. A well-designed dual-antenna
reader can usually provide 25 to 30 dB of isolation between the two signal paths,
reducing the unwanted signal in the receive chain to –20 dBm. However, when the RFID
reader antenna is facing a tag placed on a large metallic object at a distance of 12
inches, the reflected transmitter signal at the receiver input can be as high as 13dBm,
thereby eliminating any advantage of the dual-antenna design.
In actual circuit implementation, AWID developed a proprietary circuit to duplicate the
functions of the circulator, with improved directivity and isolation.

2.2. MEASURING READ DISTANCE
Make sure you know the tag types. For certain readers and tags, the user must also be
mindful of the tag’s orientation and the reader’s antenna orientation, what mounting
surface the tags are designed for and how the tags are supposed to be mounted. Any
departure from its intended purpose will drastically affect the reader’s ability to energize
the tag and its read range.
When measuring the reader’s read range, make sure that the tag is properly oriented to
the reader antenna, and for optimum performance, be sure the operator’s finger is not
within three (3) inches of the tag’s antenna surface.

3.2. PREPARATION FOR INSTALLATION
3.2.1. Bench Top Verification
It is always a good idea to verify system operation before committing to a full-scale
installation (e.g., as shown in Figure 4, page 18). The following are the necessary steps
to test reader’s operation in a static environment.
• You must first check to see if your network switch or router is equipped with PoE
(Power over Ethernet).
If switch is PoE, connect network cable to just one (1) MPR-2010AN/BN unit.
Skip the next two steps unless the IP address of connected unit cannot be
obtained.
• If your network is not equipped with PoE, obtain a power injector (PI-2000), and 48V
DC wall plug power supply and a short network RJ-45 cable (all available from AWID
under part number PI-2000, PS48-03A and RJ-45 cable).
• Connect the RJ-45 cable between the reader and “READER” port of PI-2000,
connect the wall plug power supply to POWER port of PI-2000 and connect the
Ethernet (RJ-45) cable from the Ethernet Hub (if in use) to “HUB or SWITCH” port of
PI-2000 or in the case where there is no such hub, connect from PC to the port using
a Crossover CAT5 cable.
Power up computer
Follow instructions on Local Set Up (Figure 6 or Figure 7) of an MPR-2010AN.
• Load the demo program CD onto (installation) PC and launch the demo program. Try
Connect after filling in the IP address of reader and then some commands once
connected.
3.2.2. Aiming of Antenna
Antenna Pattern for MPR-2010
MPR-2010 comes with a circular polarized antenna, to ensure reading tag with random
orientation. Most circular polarized antenna has a horizontal to vertical differential of up
to 3 dB, this will cause the antenna pattern to deviate from a true circle. AWID’s antenna

3.3. INSTALLATION STEPS
• Check to ensure that all connections are secure. Make sure all wires through the
cable clamps are anchored properly; avoid dangling wires that may become safety
hazard.
• Mount the Reader using the two recessed threaded holes to fasten to reader on the
desired mounting surface. Please note that the threaded inserts are closed ended,
user must select screws with exact length to ensure proper tightening of the
mounting screws. In cases where the reader aiming is critical, please order antenna-
mounting bracket (P/N LRMB) from AWID. This mounting bracket provides pan/tilt
adjustment for the reader. User can also drill holes through the plate as required at
the desired distance from the Reader.

4. Notes on Software Programming and System Operation
4.1. SET UP AND SYSTEM OPERATION
4.1.1. Setting Up MPR-2010AN or BN
Refer to the Set Up Procedure for MPR-2010AN/BN document.
4.1.2. Running a Custom Software Application or the AWID Demo Program
If AWID Demo Program is not used, it is expected user will launch a Custom Software
Application developed using the MPR_2010AN/BN TCP/IP Interface to send commands
as specified to the reader.
4.1.3. Operating Modes
Typical operating modes for MPR-2010 can be grouped into the following modes:
Search Mode – This mode is used when operator or user is not certain which family of tags is
placed on the items to be tracked. Since most tags are deterministic in nature, the reader must
cycle through each and every protocol, issue a protocol specific inquiry, to hail and to wait for a
response from tags of that specific protocol. Therefore, if there are many different protocols, for
an untrained observer, the reader response will become sluggish.
Mixed Mode:
This mode assumes the user is aware of the types of protocol in use, and furthermore, the
user made a determined effort to operate the reader in a mixed protocol mode. In this
mode, the user can decide how many and which specific protocols to be selected. Once
Mix Protocol Mode is selected, the reader will routinely cycle through each protocol, dwell
long enough for the reader to wait for a response and then move onto the next protocol. It
should be noted that in a mixed protocol mode, the tag must have sufficient time to
respond to the reader, and therefore, it can only be used on a conveyor belt arrangement,
with specific speed restrictions.
Single Protocol Mode
Single protocol is the normal mode of operation, where the protocol type is known and
many tags are expected to pass through the readers.
Interactive Read Mode
TBD
Autonomous Read Mode3
When the reader is in autonomous mode, the reader is placed under the control of its two
sensing inputs, which will most likely be in the form of photo sensors, ground loop
sensors, weight triggering mechanism or simple remote command. Upon receiving the
sensing input, the reader will switch to a pre-programmed single-protocol, multi-protocol
and in the case of a conveyor installation, fast-read mode and start reading functions.
Upon intercept of a RFID tag, the reader will automatically output the tag ID and after a

pre-programmed period of in-activity, the reader will switch to stand-by and wait for input
from the sensing commands.
4.2. USERS NOTE
