USR-K6 User Manual Summary

Introduction
The USR-K6 is a compact module designed for serial port to Ethernet conversion, supporting RS232 and RS485 interfaces. It features low power consumption and high efficiency due to its Cortex-M0 core.

Getting Started
Initial setup involves hardware preparation, including the USR-K6 module, cables, power supply, and a PC. The module connects to a PC via serial port and to a network via Ethernet.
