XR Series RFID Readers Ports
The available ports are:
XR450 Mono-Static Antenna Ports
Figure 2-2
XR450 Mono-Static Ports
The XR450 RFID reader configuration includes four mono-static antenna ports and four bi-static antenna ports.
The mono-static support (up to four ports), allows the XR450 RFID reader to use only one antenna per read point
for transmit/receive. This flexibility can decrease system cost and deployment complexity.
The four bi-static ports that can be utilized in either a mono-static or bi-static modes. This flexibility allows it to
provide extended bi-static performance levels for the most challenging applications and environments.
The reader also provides dense reader mode support in either bi-static or mono-static mode, enabling reliable and
efficient tag reads, in the most dense RF environments. This also eliminates interference issues associated with
multiple RFID readers in close proximity.

XR Series RFID Readers Port Descriptions
Port
Description
Antenna
(Reverse TNC)
Connect up to eight antennas - four transmit (TX), four receive (RX). Also use the four TX ports
as TX/RX ports in single port mode. The XR450 RFID reader (only) configuration also includes
four mono-static antenna ports.
10/100BaseT
Ethernet
Insert a standard RJ45 Ethernet cable for connection to an Ethernet network. Insert a
cross-connect Ethernet cable for connection to a local computer.
USB Client
For future expansion.
USB Host
For future expansion.
RS232
Insert an RS232 cable with a DB9 connector for serial console communications to a host.
Note: This port cannot be used to send data out to an external host. It is only used for local
reader control.
GPIO
Insert a DE15 serial cable for connection to external devices.
Power
DC connector connects to a Motorola approved power supply AC adapter (varies depending on
the country). Max power 24 VDC, 1.2 A.
Reset
Insert a paper clip into the hole, press and hold the reset button for more than 5 seconds. This
resets the reader configuration to factory defaults, including the password.
