Kurzbeschreibung: 2-CH UART To Ethernet Converter, Serial Port Transparent Transmission Module
Serial port transparent transmission
The2-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)
