10.9 READER MOUNTING
• Adjustable bracket: The reader (and remote antenna) must be adjustable for both “pan and tilt” (in camera parlance –
that is, horizontal and vertical) for proper aiming. See AWID’s LR-911MB (11 inch long arm, with a two-axis adjustable head).
The installer may use a camera bracket effectively.
• Fixed reader: The reader may be fastened directly to a wall, flat against the wall, in applications where the tags are on the side
of vehicles facing the reader, as on buses and large trucks, and on wheelchairs, gurneys, etc. Distance between reader and tags
should be about 5 feet to 10 feet.
• Distance from lane: For a reader on a side post, locate the reader close to the edge of the lane, but safe from side-mirrors
and errant drivers. For a reader above the lane, locate the reader as low as possible while leaving clearance for roof-racks, etc.
• Reader aiming: The “sweet spot” for reading credentials is when the credential is typically about 10 feet to 15 feet
from the reader. The goal is to have the tag about parallel to the reader’s face when the tags are read.
10.10 ELECTRIC POWER
• Isolation: For each LR-2000 reader, or for each LR-2000HiLoMA set, provide an independent DC power supply that is not used
for any other equipment. Use a separate DC power supply for each LR-2000 reader. A single power supply is used
for LR-2000HiLoMA.
• Voltage: Voltage at the reader must be between 7 volts and 15 volts DC.
• Current: For a typical 12 volts to 13.8 volts supply, current rating must be at least 1.5 amperes.
• Quality: The power supply must be linear-rated (that is, not switching) and regulated.
10.11 CABLE
• Number of conductors: Depends on whether DC power for the reader is combined with data transmission in the same cable.
Cables are usually specified in multiples of 2 conductors.
• Power: 2 conductors in shielded cable. Use 18 gauge wires between the reader and the power supply.
• Data: 3 conductors for either Wiegand interface or RS-232 interface. Use 22 gauge (18 gauge is OK).
For Wiegand, use parallel wires – not twisted pairs. For RS-232, Cat 5, twisted or untwisted, is good.
• Other specifications: Overall 100% shielded. Stranded wire. Color-coded insulation. Maximum length – 500 feet for Wiegand
data and power; 75 feet for RS-232 data at 9,600 bits per second (up to 500 feet with certain terminal equipment). High quality.
10.12 MOUNTING THE TAGS AND CARDS
• See the complete instructions for installing all credentials in Section 6.
• Attachment: The different credentials have different requirements for mounting in or on the vehicles, or for holding by hand.
Visor Tags use a molded clip for the sun visor. Hangtags hook on the inside rearview mirror or are held by fingers. Clamshell
Badges and Graphics Cards are squeezed between a finger and thumb. Windshield Tags adhere inside the windshield glass.
Rearview Mirror Tags adhere to the frame of the inside mirror, facing the windshield.
• Orientation: The flat surface of the credential should be about parallel to the face of the reader. The hand
should be behind the tag when the tag is held by the fingers. The tag may be held “portrait” or “landscape” relative to the reader;
the angle does not matter.
• Pre-installation testing: Hold the tag as intended in normal operation, or attach it temporarily (using masking tape, for example)
in the planned location. Drive the vehicle slowly through the sweet spot. Observe the LR-2000KIT’s test unit for consistent
reading. Adjust the reader’s position and aiming, and the credentials’ location, and the vehicle’s path and speed, as required.
10.13 ACCESSORIES
• LR-2000KIT Test & Set-up Kit: Absolutely required. Installation may not be supportable by AWID if this Kit is not at the site.
• Documents: Complete instructions set must be at the site with the installer.
