Direct Mounting (Without the Mounting Plate)
Not using the mounting plate can result in a read performance issue at elevated temperatures.
CAUTION
Also, if not using the mounting plate, secure the reader to prevent it from coming off of the mounting
screws.
To mount the unit without using the mounting bracket:
Use the mounting bracket as a template to locate the holes, or locate and mark the holes on 4 3/16" centers,

+/- 1/32".
For wood surfaces, drill two 1/8" diameter by 7/8" deep holes on 4.192" centers. For drywall/masonry surfaces,
2.
drill two 3/16" diameter by 7/8" deep (min) holes on 4.192" centers and install using the provided anchors.
Position the reader with the key-slot holes over the mounting screws and gently slide the reader down to lock

! When installing the antenna ensure a minimum separation distance of 9.1 in (23 cm)
WARNING
Power off the reader before connecting antennas. See
CAUTION
disconnect the antennas while the reader is powered on or reading tags. This can damage the reader.
Do not turn on the antenna ports from a host when the antennas are not connected.
CAUTION
Maximum antenna gain (including any cable loss) cannot exceed 6 dBiL.
CAUTION
For installations where the antennas are mounted externally to the building, the screen of the coaxial

cable must be connected to earth (grounded) at the entrance to the building. This should be done in
accordance with applicable national electrical installation codes. In the U.S., this is required by Section
