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)
