- 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.

3.5 GROUNDING
Grounding is critical for proper operation of MPR-2010-2.7E45V-CN readers. 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.
When using the GP I/O for sensing or display functions with a BN unit, make sure there
is no ground loop between the different sensors or displays.
For multiple LR-911 installations, it is critical that all units are connected to the same
grounding system. Using different grounding systems will create secondary current
paths or ground loops that can affect the performance and cause damage to LR-911.
