Introduction

The USR-K6 Super Ethernet Module is a compact serial-to-Ethernet module that enables transparent data transmission between an RJ45 Ethernet port and a TTL serial port. It can also be applied to RS232 and RS485 interfaces via level-shifting circuits. The K6 module features low power consumption, drawing minimal current at full operating speed. Equipped with an M0-series 32-bit processor, it delivers fast operation and higher efficiency. Its diverse functionality further meets a wide range of customer requirements. The K6 module is easy to operate and highly compatible. While adding new features, it remains compatible with the K5 configuration protocol for the convenience of existing users. Additionally, since the K6 configuration protocol is similar to that of K3, customers currently using the K3 protocol can migrate to the K6 with only minor adjustments.
