- 1. Connect the black wire (negative) first, and the red wire (positive) last. Disconnect power before any wiring changes.
- 2. The LED and Beeper lines are logic levels. Never apply power to them. They may be pulled to a low level (0 to 1.2 VDC) to enable their functions, and left floating or pulled to a high level (3.6 to 5.0 VDC) when not used.
- 3. UA-612 readers have both Wiegand-protocol and RS-232 serial interfaces. For information on RS-232, contact AWID’s technical support.
- 4. For additional information, please visit AWID’s Web site www.awid.com. For technical support questions visit www.awid.com/support or call 1-800-369-5533 (in the U.S.) or 1-408-825-1100 from 8:00 a.m. to 5:00 p.m. Pacific Time.
- 5. FCC Compliance: This equipment has been tested and found to be in compliance with the limits for FCC part 15, Class A digital device. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instruction manual, may cause harmful interference with radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
- The users are prohibited from making any change or modification to this product. Any modification to this product shall void the user’s authority to operate under FCC Part 15 Subpart A Section 15.21 regulations.
- This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

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 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
equipment/devices. It should be noted that BR and BN 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.
• Make sure that the supply voltage of the reader is within specification
• Use cables with over-all braid or shield
• 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
The reader 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.
