RS232/485/422 To RJ45 Ethernet Module ETH (B)

The Rail-Mount Serial Server is a versatile and reliable solution designed to seamlessly integrate your serial devices into an Ethernet network. This module supports RS232, RS485, and RS422 communication protocols, allowing you to connect a wide range of serial devices such as PLCs, sensors, and industrial equipment to an ethernet network via the RJ45 Ethernet port.

With its TCP/IP to serial conversion capability, the Rail-Mount Serial Server enables bidirectional communication between your serial devices and the network, providing real-time data transmission and remote access to your devices. The module’s common network port simplifies integration into existing ethernet networks, eliminating the need for complex configurations. Its electrical isolation feature ensures reliable and secure data communication, protecting your serial devices from potential voltage spikes and ensuring the integrity of your data in industrial environments.

Additionally, the Rail-Mount Serial Server supports MQTT and JSON protocols, empowering seamless integration with cloud-based platforms and edge computing systems. MQTT enables efficient and lightweight messaging, making it ideal for low-bandwidth and high-latency networks, while JSON data representation provides a flexible and user-friendly format for data exchange and integration into web-based applications and databases.

With a sturdy rail-mountable enclosure, providing easy installation, seamless and secure serial device integration, real-time data communication, remote access capabilities, robust design and comprehensive features, this module is a reliable and essential component for your industrial communication needs.

Features

• Support TCP server, TCP client, UDP mode, and UDP multicast. When used as a TCP client, it also supports TCP server functions. It supports 30 TCP connections as a TCP server and 7 destination IPs as a TCP client.
• The baud rate supports 1200~115200bps, the data bit supports 5~9 bits, and the parity bit can be in five ways: no parity, odd parity, even parity, mark, and space.
• Supports the function of sending MAC address on device connection, which is convenient for cloud management of devices.
• Provides a secondary development kit DLL development library for searching and configuring devices on the computer side.
• Web browser configuration, support DHCP to obtain IP dynamically, and DNS protocol to connect domain name server address.
• Cloud remote search for devices, configure device parameters and upgrade device programs.
• View the TCP connection status, and the data sending and receiving of the serial port. The virtual serial port also supports the monitoring function.
