3 INSTALLATION & OPERATION GUIDELINES
For ease of explanation, MPR reader in this section refers to an MPR-3014 reader
model, i.e., a unit that consists of MPR-1510 (3.2e) inside a splash proof, UV
stabilized housing case and high performance circular polarized antenna(s).
3.1 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 reader is not installed properly, the performance will
be degraded. Listed below are steps that should be followed during installation:
·
Do not install the MPR 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 MPR 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 MPR reader in close proximity to other 900 MHz wireless
local area networking (WLAN) equipment. It should be noted that MPR-2010s (, etc.
are known to work in electromagnetic crowded areas, such as trade shows.
3.2 PREFERRED READER INSTALLATION PRACTICES
·
Avoid mounting the MPR reader under direct sunlight. Exposure to direct sunlight
may cause the reader to operate at a temperature above the 65 degrees Celsius
upper limit.
·
Make sure that the supply voltage of the MPR 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
An MPR-3014 reader uses uni-directional antennas each 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 MPR reader wiring should be continuously shielded. AWID recommends using
#24 AWG up to #22 AWG, longer distances and higher current consumption on the
