ZLAN5443A is a new generation of 4 serial server developed by Shanghai ZLAN Information Technology Co., Ltd. It can realize 4 serial port data to TCP/IP, and supports two 10M/100M Ethernet ports. ZLAN5443A Modbus gateway function that converts Modbus TCP to Modbus RTU. The Modbus gateway supports simultaneous data reading on multiple Modbus client connections, i.e., the "multi-master" function.

ZLAN5443A supports 4 RS232 serial ports and 4 RS422/485 serial ports. The user connects the ZLAN5443A to the network through a network cable, and the host computer can access four serial ports at the same time through the virtual serial port or TCP protocol.

ZLAN5443A supports expansion to 8 serial ports, 12 serial ports, 16 serial ports, and up to 32 serial ports through the level networking port.

Peculiarity

Hardware features:

• All 4 serial ports support RS232, RS485, RS422 three serial ports.
• The 4 serial ports can work independently and fully duplex, without interfering with each other, and can be configured for different baud rates.
• It supports the network switch function of 2 network ports and can be used as a switch at the same time.
• Abundant indicators, each serial port has independent TCP connection indicators and data activity indicators.

Software features:

• TCP server, TCP client, UDP mode, and UDP multicast are supported. Supports 10 TCP connections as a TCP server.
• The baud rate supports 1200~460800bps, the data bit supports 5~9 bits, the check bit can be no check, odd check, even check, mark, space five ways, support CTS/RTS hardware flow control and XON/XOFF soft flow control.
• It supports sending MAC addresses on device connections, which is convenient for cloud management.
• Provide a secondary development package DLL development library for searching and configuring devices on the computer side.
• DHCP dynamically obtains the domain name server address of the IP and DNS protocol connections.
• It supports remote search for devices and configuration of device parameters in the cloud.
• You can remotely view the TCP connection status of a device through the software. The virtual serial port supports data monitoring function.
• It supports Modbus gateway function and Modbus RTU to Modbus TCP.
• Support multi-host function: In the one-question-and-answer query mode, the network port allows multiple computers to access the same serial port device at the same time.
