Summary

ZLAN5443D is a 4-serial port serial port server /Modbus gateway mounted on a guide rail, RS485 with optocoupler isolation, which can effectively isolate the interference on the RS485 bus to ensure the stability of the device. It is suitable for use in the environment where the RS485 bus has interference. Built-in power supply lightning protection, 9 ~ 24V wide voltage, terminal type power access, with shell node cable.

ZLAN5443D adopts guide rail design, with guide buckle on the back; At the same time, it is also equipped with the above two mounting ears, which can be mounted horizontally or vertically, respectively suitable for installation to the backplane or the desktop.

ZLAN5443D can realize the conversion of 4 TCP/IP protocols to RS485/422/232, 4 channels work at the same time and can be configured for different baud rates. It can realize the data acquisition of 485 devices through the network, and the network side can use the virtual serial port to connect the serial port software or the direct TCP/IP communication software. Comes with two 10M/100M network ports, you can connect any network port. The other network port can be cascaded to multiple ZLAN5443D serial ports through network cables, which can be cascaded to 8 serial ports, 12 serial ports, and 16 serial ports.

ZLAN5443D supports Modbus RTU to Modbus TCP and has the feature of storage Modbus gateway. It can also be used as a non-storage Modbus gateway.

ZLAN5443D can be used in:
power electronics, intelligent meters and energy consumption monitoring;
As a gateway to the Internet of Things as a communication bridge between devices and the cloud;
All kinds of automation PLC remote monitoring and program download;
Various configuration software and device communication interfaces;
Access control security field equipment networking;
Network information collection of medical equipment;

Typical application connections are shown in the figure. The original serial device is connected to the serial port of ZLAN5443D, and the 5443D is connected to the computer through the network cable. The software on the computer connects to 5443D through TCP/IP or virtual serial port. Thereafter, any data sent by the serial device is transparently transmitted to the computer's software, and the data sent by the software to the ZLAN5443D over the network is transparently transmitted to the serial device.

Feature

    Hardware peculiarity

  • There are three ways to install guide rail, backplane mounting ear and desktop mounting ear. Especially suitable for industrial rail installation, due to the narrow transverse width can save installation space, installation, disassembly more convenient.
  • RS485 Serial port optocoupler isolation, isolation voltage 1500V. It is suitable for high-interference environments where common serial port servers cannot work properly. Effectively isolate the ground circuit between the serial device and the serial server.
  • Built-in power surge protection: built-in varistor and ceramic discharge tube can effectively protect the internal circuit of serial server in case of power surge.
  • Industrial power supply mode: terminal connection mode, easy to use in industrial occasions. Can be 9 ~ 24V wide voltage supply. With housing ground wire, effective diversion interference and surge.
  • Dual network port design, support serial port server cascading, expansion to 8 serial port, 12 serial port, 16 serial port, etc.
  • Abundant panel indicators for easy debugging: In terms of connection, there are not only 100M_LINK lights indicating whether the network cable is properly connected, but also LINK lights indicating the establishment of TCP connections; For data indicators, there are independent indicators for serial port to network port and network port to serial port. Easy to debug on site.

    • Software peculiarity

  • 4 serial ports can be configured for different baud rates, independent work, do not interfere with each other.
  • Support TCP server, TCP client, UDP mode, UDP multicast. As a TCP client, it also supports TCP server functions. The TCP server supports 30 TCP connections and the TCP client supports 7 destination IP addresses.
  • The baud rate ranges from 1200 to 115200bps. The data bits range from 5 to 9 bits. The parity bits can be none, odd, even, mark, or space.
  • Supports the function of sending MAC addresses when the device is connected, facilitating device management in the cloud.
  • Provides a secondary development kit DLL development library for computer side search and configuration devices.
  • Support Web browser configuration, support DHCP dynamic IP, DNS protocol to connect to the DNS server address.
  • Support cloud remote device search, device parameter configuration, device program upgrade.
  • Supports remote viewing of TCP connection status, serial port data sending and receiving status through software. The virtual serial port supports data monitoring.

    • Advanced Software features

  • Supports the Modbus gateway function and transfers from Modbus RTU to Modbus TCP. It can support storage Modbus, which can automatically collect device data and store it. Non-storage Modbus gateways are also supported.
  • Multi-host: In the question-and-answer query mode, the supported network port allows multiple computers to access the same serial port device at the same time.
  • Support custom heartbeat packet and registration packet functions: can facilitate communication and device identification with the cloud.
  • Supports the password authentication function for TCP connection establishment to ensure connection security.
  • supports http data submission and delivery functions, and the cloud can directly interact with the serial port data of the device using the http GET command.
