Installation involves many of the same connection steps required for bench test.
However, instead of placing equipment on a tabletop, the reader, antenna, and
their accessories are mounted in your application environment.
Requirements
Before installing your RFID Reader system, you will need the following:
An 802.3af compliant network connection or standard 120 or 220 VAC
power outlet
WARNING
: If you do not use an 802.3af compliant network to supply
DC power you must use the ALX-416 power supplies provided by Alien
Technology. Failure to do so voids the product warranty and violates the
terms of the FCC license.
RS-232 cables, Ethernet cables or antenna coax cables needed to
accommodate routing requirements
Mounting hardware suitable for the surface to which equipment is to be
attached. Use #8 pan head screws 1.125” minimum length
Hardware Installation Procedure
1. Select mounting position for antenna(s).
CAUTION: Reader antenna should be positioned so that personnel in
the area for prolonged periods may safely remain at least 23 cm (9 in) in
an uncontrolled environment from the antenna’s surface. See FCC OET
Bulletin 56 “Hazards of radio frequency and electromagnetic fields” and
Bulletin 65 “Human exposure to radio frequency electromagnetic
fields.”
Mount the reader and antenna(s) at the periphery of the desired read
window so that the position of the most distant tag passing through the
window is no farther from the antenna than the maximum range specified
for your system design.
Position the reader and antenna(s) at a height approximately midway
between the highest and lowest expected tag position. (For example, a
pallet tag may be the lowest tag position to be read, while the top-most
case on a fully stacked pallet may represent your highest tag position.)
NOTE
: To maintain compliance with FCC regulations, use only
antennas, cables, and power supplies supplied with the unit or approved
by Alien Technology for use with the ALR-9680.
2. Select mounting position for reader.
The ALR-9680 has been designed to provide reliable operation over its
operating temperature range. This is enhanced by proper mounting of the
reader during bench test and installation. Place the reader on a solid,
thermally conductive surface. Optimum thermal performance is achieved by
mounting the unit to a metal mounting plate with direct contact between the
reader base and the mounting plate. When mounting vertically the reader IO
panel should be oriented at the bottom.
Antennas should be placed close enough to the reader to accommodate
the cable length without putting strain on the connectors.
