·  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.

3.5  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.
