1. Product Overview
1.1. Introduction
ARU5321M&x is a high-stability industrial-grade UHF RFID reader device,
integrated based on the UHF RF chip E710. It operates in the frequency band of
865~930MHz (customizable, including US standard 902~928MHz, EU standard
865.6~867.6MHz, and national standard 920~925MHz), and supports reading tags that
comply with the ISO18000-6C and EPC Class1 Gen2 international standard protocol
formats.
The device has built-in filtering and isolation modules, providing strong
anti-interference capabilities for EMC. It also features easy operation, excellent sealing
and heat dissipation, high receiving sensitivity, stable performance, and high reliability.
Equipped with RS485 and TCP communication interfaces, the RS485 interface supports
the standard industrial communication protocol ModBus RTU, while the TCP interface
has multiple standard Ethernet industrial communication protocol versions including
ModBus TCP, PROFINET, EtherNet/IP, and CC-LINK IE FB, allowing users to easily
integrate it into PLC and other control systems. The reader integrates the RF
communication protocol internally, so users do not need to understand complex RF
communication protocols. They can achieve inventory UID, read storage area, and write
storage area by operating the holding registers and input registers inside the reader
through ModBus, PROFINET, EtherNet/IP, and CC-LINK IE FB commands.
This product is suitable for industrial fields such as automated production lines,
automated sorting systems, and component assembly lines.

The default IP address of the reader is 10.168.1.222, and the default port is
502.
The ARU5321M&T product can be powered by DC 24V (10~30V) or 48V POE
(46~54V, IEEE802.3af). The product supports both power supply methods, but only one
method needs to be selected for actual use.
The ARU5321M&P, ARU5321M&E, and ARU5321M&I products are powered
by DC 24V (10~30V).

3. Communication Connection
3.1. Ethernet Connection Instructions
The ARU5321M&x reader and commonly used PLC can be networked through the
Ethernet switch.
Figure 2 Product working network topology
3.2. Serial Port Connection Instructions
When a single ARU5321M&x reader is connected to a PLC via the RS485 serial
port, direct connection is sufficient.
Figure 3 ARU5321M&x stand-alone connection to PLC(RS485)
The RS485 bus supports multiple ARU5321M&x readers to be mounted on the
same bus for multi-machine networking. When multiple readers are mounted on the bus,
120Ω matching resistors should be connected to the front and rear ends of the bus to

3.3. Connector Instructions
3.3.1. Ethernet Cable
Figure 5 Industrial Ethernet cable
When the product uses POE power supply, the ARU5321M&T only needs one
industrial Ethernet cable. To improve communication reliability and system EMI
performance, it is recommended to use CAT5E standard industrial Ethernet cable as the
communication cable. The theoretical communication distance is up to 100 meters, and
it is recommended to use within 80 meters in actual applications.

3.3.2. DC Power Supply and Serial Communication Cable
One end (M12A female connector) of the DC 24V power supply cable is connected
to the reader, and the other end (M12A male connector) is directly connected to the
power supply; or a 2-way splitter can be used to power multiple readers with one power
supply. The 5-core cable contains 2 power wires (1, 3), 2 serial communication wires (2,
4), and 1 ground wire (5).

5.2. Product Installation Method
This device can be fixed to the desired position with 4 M5 screws, and custom
installation brackets can be provided according to the customer's on-site installation
environment. If there is a metal plate on any side of the reader, the reader should be at
least 50cm away from the metal plate, otherwise, the reader's RF signal will be affected,
resulting in the reader's reading distance not reaching the expected distance or even
being unable to read at all.
Figure 10 Product installation instructions
Since the RF signals between readers will interfere with each other, a certain
distance must be maintained between any two readers to avoid mutual interference,
whether installed sideways or facing each other.
