Connecting Antennas

CAUTION Power off the reader before connecting antennas. See
disconnect the antennas while the reader is powered on or reading tags (when the yellow LED is lit).
This can damage the reader.
CAUTION Do not turn on the antenna ports from a host to which the antennas are not connected.
To connect the antenna pairs to the reader*:
Attach the N connector of an antenna cable to antenna 1.
1.
Attach the reverse TNC connector of the cable to a TX antenna port.
2.
Secure the cable using wire ties. Do not bend the cable.
3.
Attach the N connector of a second antenna cable to antenna 2.
4.
Attach the reverse TNC connector of the cable to an RX antenna port.
5.
Repeat steps 1-5 to connect the remaining antenna pairs to the reader.
6.
Secure the cable using wire ties. Do not bend the cable.
7.
*Installation for the XR450 is the same except that the XR450 can be run in mono-static mode which only requires
one antenna for both transmit and receive.

Portal Setup

In portal situations (dock doors) set the TX for an antenna on one side of the portal to face the TX of the opposing
antenna (except for the XR450, in mono-static mode). Similarly, ensure that the antenna RXs face each other.
