3 INSTALLATION & OPERATION GUIDELINES
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-2010AR 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-2010AR readers
are known to work in electromagnetic crowded areas, such as trade shows.
3.2 PREFERRED READER INSTALLATION PRACTICES
• Avoid mounting the 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 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-2010AR 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.
