1 INTRODUCTION
AWID's Sentinel-Sense MPR-1712 is a Radio Frequency IDentification (RFID) reader
module with RS-232 and USB I/O interface that works with most leading passive UHF
and HF tags. The reader module comes with a unique combination of long read range,
small size (credit card), dual frequency and low power consumption. Its primary
applications are access control, asset management and tracking, and fleet management
applications.
The MPR-1712 reader modules are delivered with firmware version US0-211h1-xx.yy.00.
In order to operate an MPR-1712 you will need the following:
PC running Windows1 2000 or higher, CD-ROM drive, USB and/or RS-232 serial
port.
Host software (AWID’s demo software or your own custom software)
1.1 SPECIAL FEATURES

2.3 MEASURING READ DISTANCE
Make sure you know the tag types. For certain readers and tags, 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 INSTALLATION & OPERATION GUIDELINES
For ease of explanation, MPR reader in this section refers to an RFID device that
consists of MPR-1712 and a high performance circular polarized antenna inside a
splash proof, UV stabilized housing case. The module should be installed on a heat
sink. Example of a heat sink could be an aluminum plate of size 8”x8”x0.1” exposed to
convection air flow. The screws at the bottom of module shall be used for mounting the
module on the heat sink.
3.1 GENERAL WIRING REQUIREMENTS
All the MPR reader wiring should be continuously shielded. AWID recommends using
#24 AWG up to #22 AWG, longer distances and higher current consumption on the
power supply line will require larger gauge wires.
TABLE 3.4-1: Data Line’s Wiring Requirement
WIRE SIZE #22 AWG (0.6 mm Dia.) #24 AWG (0.5 mm Dia.)
RS-232 50 ft (15 meters) 50 ft (15 meters)
3.2 WIRING DIAGRAMS
See section 2.2 for pin assignment for the RS-232 connector of MPR-1712.
The MPR RS-232 interface is a short distance serial interface, a full command set for
the standard serial interface is not necessary, therefore only transmit, receive and
ground wires are used. Sense input is an enable input, which is traditionally used to
activate the RF energy of the reader and to start the read functions.

4 INSTALLATION PROCEDURE
This section provides installation and operation information for MPR-1710 reader modules.
4.1 PARTS LIST
Verify that all items listed below are present before starting the installation.
o Sentinel-Sense MPR-1712 Qty=1
o Documentation and command demo program CD Qty=1
4.2 PREPARATION FOR INSTALLATION
Familiarize yourself with the connectors and pin out assignment of each I/O connectors.
4.2.1 Bench Top Verification
It is always a good idea to verify system operation before committing to a full-scale
installation. The following are the necessary steps to test the reader’s operation in a
static environment.
Connect MPR-1712 to the RS-232 or USB port of a PC
Connect the power jack from the wall plug power supply to reader module
Power up PC
Install demo software on PC
Activate demo software and verify performance of the reader.
Select a COM port in program window then click “Connect”. Follow with some
commands.

5 SOFTWARE PROGRAMMING AND SYSTEM OPERATION NOTES
5.1 SYSTEM OPERATION
5.1.1 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-1712 Protocol to issue commands to the MPR
reader/module as specified.
5.1.2 Operating Modes
Typical operating modes for MPR readers can be grouped into the following modes:
Search Mode
This mode is used when operator or user is not certain what family of tags is placed on
the items to be tracked. Since most tags are deterministic in nature, MPR 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 appear 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 on to 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.
5.2 USERS NOTE
For System Integrators and/or Software Developers
System Integrators and/or software developers should get familiar with the MPR-1710
1712 Protocol specifications for developing applications that control an MPR-1710.
For Custom System Users
For custom system user, please refer to your host software user guide for information
regarding system and software operations
For Demo Software Users
MPR-1712 - 11 - 6/19/2008
If you are using the AWID RFID demonstration software application which is .NET based
with easy-to-follow GUI operations, simply select the COM port for which the device is
configured then click “Connect” should get you started.
