1. Summary
ZLAN5143D is a kind of RS485 device data collector/IOT gateway specially designed
for industrial environment, which integrates serial port server, Modbus gateway, MQTT
gateway, RS485 to JSON and other functions. It has an RS485 interface and RJ45
interface. It uses guide-way type installation way, the volume is compact and
installation is convenient. Terminal type power supply access, 9~24V wide voltage
input. Because there is only RS485 interface, the RS232 interface which is not
commonly used on industrial instruments is cancelled, which saves the cost and
volume and has a higher cost performance ratio compared with ordinary products.

When used as a normal serial port server, the 5143D network port is connected to the
RJ45 Ethernet. The host computer software can use TCP/UDP transmission mode or
virtual serial port mode to send data to the 5143D RS485 interface. Data received on
the RS485 interface is also transferred to software or virtual serial ports on the TCP

end. Under the mode of virtual serial port, the serial port software connected to virtual
serial port can be used without any configuration.
When used as Modbus gateway, 5143D supports Modbus TCP to Modbus RTU, so as
to realize data acquisition of RS485 Modbus RTU device by upper computer using
Modbus TCP protocol. On the contrary, it can be used if RS485 terminal as the master
station. 5143D supports more advanced Modbus gateway functions, including
configurable Modus gateway ZLMB, storage Modbus gateway, etc., which fully meets
all kinds of configuration and usage of Modbus gateway. The multi-host feature allows
multiple computer master stations to simultaneously access one RS485 slave device.
When used as MQTT gateway, the device can upload the serial port data to MQTT
server in the way of transparent transmission through MQTT protocol. Supported
servers include BAIDU cloud MQTT, ALI cloud MQTT, China mobile OneNet platform,
etc. It is supported to parse the collected Modbus RTU or non-standard serial port
data into JSON format and encapsulate it into MQTT packet for uploading.
It supports JSON format to upload and collect data, and the data is automatically
collected. The collected data supports Modbus RTU, 97 version of 645 meter, 07
version of 645 meter, and various non-standard RS485 protocols. The user can
configure the uploaded data format and JSON keywords with ZLVircom. When
uploading, MQTT protocol, HTTP POST protocol, HTTP GET protocol, transparent
transport protocol and various non-standard network protocols can be supported.
Among them, ZLAN5143DN model supports P2P networking, no need to relay
through the server, and connect the device through ID.
ZLAN5143D has powerful functions of IOT gateway, which is very suitable for
collecting all kinds of RS485 instruments and sensors in the industrial field, including
collection of local network or uploading to cloud server for independent collection and
posting.
ZLAN5143D can be applied to:
As the gateway of IoT and the communication bridge between devices and cloud;

Power, intelligent instrument and energy consumption monitoring;
All kinds of automation PLC remote monitoring and program download;
All kinds of configuration software and equipment communication interface;
Networking of access control and security equipment;
Typical application connections are shown in figure 2. The original serial port device
RS485 is connected to the RS485 port of ZLAN5143D, and the 5143D is connected to
the computer through the network cable. The software on the computer connects to
5143D via TCP/IP or virtual serial port. Thereafter, any data sent by the serial device
will be transmitted transparently to the computer's software, and the data sent by the
software to ZLAN5143D via the network will also be transmitted transparently to the
serial device.

2. Features
2.1 Hardware characteristics
ZLAN5143D has the following features:
1) Guide-way design: suitable for internal installation of cabinet in industrial field.
2) Compact size: relative to the ordinary serial port server, the width is small, does
not take up space.
3) Terminal type power supply, 9~24V wide voltage input, with anti-opposite power
connection protection.
4) Terminal RS485 interface, support 32 slave devices, baud rate support 300 ~
115200bps.
5) Abundant panel indicator light for debugging: in connection, not only indicates
whether the network cable is connected to the RJ45 interface light, but also
indicates the LINK light TCP connection established; Data indicator light has
"serial port to network port", "network port to serial port" independent indicator
light.
2.2 Software functions
1) Support TCP server, TCP client, UDP mode, UDP multicast. Support TCP server
side function as TCP client. Support 30 TCP connections as a TCP server and 7
destination IP as a TCP client.
2) The baud rate supports 1200~115200bps, data bits support 5~9 bits, and parity
can be None, Odd, Even, Mark, Space. CTS/RTS hardware flow control and
XON/XOFF soft flow control.
3) Support the function of sending MAC address when device connecting to
facilitate cloud management of devices.
4) Provide search, configure the device secondary development package DLL on
PC.
5) Support Web browser configuration, support DHCP dynamic access IP, DNS
protocol connect domain name server address.

6) Support remote search device, configure device parameter, device program
upgrade on cloud.
7) Support remote viewing of TCP connection status, serial port data sending and
receiving status of devices through software. Virtual serial port supports data
monitoring.
2.3 Advanced software features
The 4 number in 5143D indicates that advanced soft functions are supported,
including:
1) Support Modbus gateway function, support Modbus RTU to Modbus TCP. The
storage Modbus can be supported, and the equipment data can be collected
automatically and stored. Modbus gateway for non-storage mode is also
supported.
2) Support for multiple hosts: support Ethernet port allows multiple computers to
access the same serial port device at the same time in a question-answer query
mode.
3) Support for MQTT gateway functionality.

communicate with the cloud and device identification.
7) Support TCP to establish a connection requires password authentication function,
to ensure the security of the connection.
8) Support "transcoding" function, can achieve specific device protocol translation
work, so that different devices docking unified software platform.
9) Support HTTP data submission and delivery functions, the cloud can directly use
HTTP GET instructions and device serial data for interaction.
