Introduction

This is a serial TTL to Ethernet module, used for data transparent transmission. USR-K3 is the high-performance and industrial version of Super Port. It is an embedded serial networking module, whose function is to realize bidirectional transparent transmission between TTL and Ethernet. The amazing part of K3 lies in its Ethernet port integration design. You can apply K3 to your products to realize networking communication. User can directly process data interaction through network and device to realize remote data acquisition, remote control and management.

K3 is based on Cortex-M4 solution, which has high speed,high stability and basic frequency up to 120MHz. And it has the same kernel solution and parameters as USR-TCP232-E2.

Features

• Cortex-M4 kernel,industrial working temperature range and TCPIP protocol stack.
• Auto-MDI/MDIX,RJ45 port with 10/100Mbps
• TCP Server,TCP Client,UDP Client,UDP Server and HTTPD Client work mode
• Support virtual serial port and provide corresponding software USR-VCOM
• Serial port highest baud rate from 600bps to 1024Kbps, Check bit of None,Odd,Even,Mark and Space
• DNS and DHCP supported
