Hardware Installation Procedure

1. Select mounting position for antenna(s).

CAUTION: Reader antennas 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 antenna(s) at the periphery of the desired read window (either

overhead or at the side), 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 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.)

• If you are using two antennas, mount the second antenna in a mirror-

image of the first antenna’s position, unless otherwise indicated in your

system design specification.

• NOTE: To maintain compliance with FCC regulations, only use antennas

supplied with the unit.

2. Select mounting position for reader.

• Reader should be positioned close enough to the antenna to

accommodate the cable length without putting strain on the connectors.

• Be sure power is available to the selected reader location.

3. Select location for host PC.

• Situate the host PC within 50 ft of the reader in a safe location away from

vehicular and foot traffic.
