3 - 4 FX Series RFID Readers Integrator Guide
Direct Mounting (Without the Mounting Plate)
To mount the unit without using the mounting bracket:
1.
Use the mounting bracket as a template to locate the holes, or locate and mark the holes on 4 3/16” centers,
+/- 1/32”.
2.
For wood surfaces, drill two 1/8" diameter by 7/8" deep holes on 4.192" centers. For drywall/masonry surfaces,
drill two 3/16" diameter by 7/8" deep (min) holes on 4.192" centers and install using the provided anchors.
3.
Position the reader with the key-slot holes over the mounting screws and gently slide the reader down to lock
into place.
4.
Adjust the screw head height to assure a snug fit. Or if the screws are accessible from the back, use machine
screws with a lock washer/nut and tighten the nut (from the back) to secure the reader.
Connecting Antennas
To connect the antennas to the reader (see Figure 3-2 ):
1.
Attach the antenna reverse TNC connector to an antenna port.
2.
Repeat Step 1 to connect the remaining antennas to the reader.
3.
Secure the cable using wire ties. Do not bend the cable.
CAUTION
Not using the mounting plate can result in a read performance issue at elevated temperatures.
Also, if not using the mounting plate, secure the reader to prevent it from coming off of the mounting
screws.
WARNING
! When installing the antenna ensure a minimum separation distance of 9.1 in (23 cm)
between the antennas and all persons
.
CAUTION
Power off the reader before connecting antennas. See Powering the Reader on page 3-5 . Never
disconnect the antennas while the reader is powered on or reading tags. This can damage the reader.
CAUTION
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
820.93 of the National Electrical Code, ANSI/NFPA 70.
