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.
3.1
INSTALLATION & OPERATION GUIDELINES
SITE SURVEY
Always conduct a site survey before starting installation. Avoid any possible sources of
interference. For best result, use a spectrum analyzer with a wideband antenna and set
the spectrum analyzer in Max Hold mode to gain measurement of the maximum signal
strength on the airwave. If the MPR-2010BR reader is not installed properly, the
performance will be degraded. Listed below are steps that should be followed during
installation:
· Do not install reader in an area where sources of broadband noise may exist.
Avoid mounting the reader facing a cellular phone tower or in close proximity to the
base station of a 900 MHz wireless telephone.
· Keep all of the reader wiring a safe distance from all other wiring, including, but
not limited to, AC power, computer data wiring, and telephone wiring, and wiring to
electrical locking devices.
· Avoid operating the reader in close proximity to other 900 MHz wireless local
area networking (WLAN) equipment. It should be noted that MPR-2010BR readers
are known to work in electromagnetic crowded areas, such as trade shows.
3.2
PREFERRED READER INSTALLATION PRACTICES
· Avoid mounting the under direct sunlight. Exposure to direct sunlight may cause
the reader to operate at a temperature above the 65 degrees Celsius upper limit.
MPR-2010BR
·
·
·
·
·
·
Page 8
Doc# 041318
Make sure that the supply voltage of the reader is within specification
Use cables with over-all shield (screen)
For best results, avoid bundling data cable with AC power and computer cables
Use the largest wire gauge where feasible
Use dedicated power supply, where necessary
Use Single Point Grounding, and avoid ground loops
3.3
MOUNTING PREFERENCE
MPR-2010BR has a uni-directional antenna with an antenna beam width of about 60-70
degrees. The radiation pattern is an oval-shaped beam, which should be aimed toward
where the transponders will pass.
3.4
GENERAL WIRING REQUIREMENTS
All the 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. PG I/O output are standard access industry
Wiegand drivers, which is capable of 500 feet driving distance.

WIRING DIAGRAMS
See section 2.2 for pin assignment for the RS-232 connector.
MPR-2010BR s 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.

3.6 GROUNDING
Grounding is critical for proper operation of MPR-2010BR. When installing the reader, it
is crucial to assure that the earth ground is the best ground available. If you elect to use
the 120 VAC power ground, conduct a test by measuring its resistance relative to a
known good ground, such as a cold water pipe or structural steel that is in direct contact
with the ground. The resistance should be less than 50 ohms.

as shown in section 2.2.1.
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-2010BR to the RS-232 port of a PC
Connect the power jack from the wall plug power supply to MPR-2010BR.
Power up PC
Install demo software on PC
Activate demo software and verify performance of the reader.
Select COM port 1 on top page then click Connect . Follow with some
commands.
Place the RFID tags at the exact same locations as the final configuration
Measure tag s read distance and confirm that read distance is correct.
4.2.2 Aiming of Antenna
Antenna Pattern for MPR-2010BR
MPR-2010BR
Page 10
Doc# 041318
MPR-2010BR 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 has a horizontal to vertical differential of typically less than 0.5 dB,
making its pattern as near to a circle as possible.

INSTALLATION STEPS
1) 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 a
safety hazard.
2) 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 closedended, the user must select screws with the 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. Users can also drill holes
through the plate as required.
3) Adjust the position or the angle of the reader so that the tags are detected and
read at the desired distance from the reader.
5.1
SOFTWARE PROGRAMMING AND SYSTEM OPERATION NOTES
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 Serial Communication Protocol to issue
commands as defined by the protocol to reader.
5.1.2 Operating Modes
Typical operating modes for MPR-2010BR readers can be grouped into the following:
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, 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
