3 - 4 FX7500 RFID Reader Integrator Guide
Connecting Antennas
To connect the antennas to the reader (see Figure 3-2):
1. For each antenna, attach the antenna reverse TNC connector to an antenna port.
2. Secure the cable using wire ties. Do not bend the cable.
Figure 3-2 FX7500 RFID Reader Antenna Connection
WARNING! When installing the antenna ensure a minimum separation distance of 13.4 in (34 cm) between
the antenna and all persons.
CAUTION Power off the reader before connecting antennas. See Powering the Reader on page 3-10. Never
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.
Maximum antenna gain (including any cable loss) cannot exceed + 6.6dBiL. See Table 3-1 for
corresponding maximum conducted RF power at antenna input.
When mounting the antennas outside the building, connect the screen of the coaxial cable to earth
(ground) at the entrance to the building. Perform this 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.
WARNING! For Mounting in Environmental Air Handling Space (EAHS): Do not install Antennas and
Antenna Cables in the EAHS unless they are suitable for use in EAHS as per UL 2043.
