RS232/485/422 - RJ45 Ethernet Module

This RJ45 Ethernet Module facilitates bidirectional transparent data transmission between RS232/485/422 and RJ45 Ethernet connections. It supports various communication formats, including TCP Server / TCP Client / UDP Mode / UDP Multicast. It offers flexibility in converting between different protocols, from MQTT/JSON to Modbus, with Modbus grid upgrade support and custom configuration software.

The Ethernet port can simultaneously send data to three serial ports, but only one of RS232, RS485, or RS422 can send data to the Ethernet port at a time. It features a built-in power supply, signal isolation, built-in TVS (transient voltage suppression diode) to suppress overvoltage, lightning protection, ESD protection, and an aluminum alloy enclosure, making it a robust, durable, and secure device.

Multiple configuration methods, NTP protocol support (used to synchronize computer time sources in a network), support for multiple master polling, screw terminals for power supply, DC power connection point, and PoE Ethernet connection point, a rail-mounted clip design for assembling multiple rail-mounted serial servers, and a small size for easy installation. This module is excellent for your transmission and communication needs.

Specifications

• Supports TCP Server, TCP Client, UDP Mode, and UDP Multicast. When used as a TCP Client, it also supports TCP Server functions, supporting up to 30 TCP connections as a TCP server and 7 target IPs as a TCP client.
• Supports baud rates from 1200 to 115200 bps, data bits from 5 to 9 bits, and five options for parity bits: none, odd, even, mark, and space.
• Supports sending MAC addresses in device connections for cloud management of devices.
• Provides a secondary development kit DLL development library for searching and configuring devices on the computer side.
• Supports web browser configuration, DHCP for dynamic IP allocation, and DNS protocol to bind to domain name server addresses.
• Allows remote device search, device parameter configuration, and device program upgrades in the cloud.
• Supports displaying TCP connection status and serial port data sending and receiving status. The virtual serial port also supports monitoring functionality.
