2-CH UART To Ethernet Converter, Serial Port Transparent Transmission Module 2-CH UART TO Ethernet Converter

Serial port transparent transmission

Features At A Glance

The 2-CH UART TO ETH provides an easy way to communicate between UART TTL and RJ45 Ethernet, allowing bi-directional transparent data transmission. It is easy to use, along with features like fast data rate, low power consumption, high stability, suits applications such as safety &security, IoT, and so on.

• Embedded Ethernet MAC and PHY layers
• Bi-direction transparent data transmission between UART and Ethernet
• 10/100M, full-duplex/half-duplex auto-negotiation Ethernet interface, 802.3-compliant
• Auto-MDI/MDIX, detect and switch cable type automatically
• Supports DHCP auto-obtained IP and DNS domain access
• Network parameter configuration like chip operating mode, port, IP, via host computer software or UART command
• Four operating modes: TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER
• 2-CH UART concurrent operation, standalone transparent transmission for each channel
• Full-duplex or half-duplex UART communication, supports RS485 RX/TX auto switch
• Supports virtual serial port software (provided)
• KEEPALIVE mechanism support
• Comes with development resources and manual (examples for Pico/Raspberry Pi/Arduino/STM32)
