Product Overview

Kyland KPS3224A Serial Server is an 1U rack-mount industrial serial server. It is mainly used to connect serial port equipment to Ethernet, the serial port data can be read through the network and the serial port device can be remotely controlled. Kyland KPS Serial Server not only supports TCP client, TCP server and UDP network communication modes, but also supports transparent transmission and Modbus RTU data transmission protocol.

Kyland KPS3224A Serial Server support 8 RS232 serial port and 16 RS485 or 8 RS422 serial port. The product provides 120 Ω switchable terminal resistance to reduce signal reflection and effectively improve the stability and reliability of RS485/RS422 serial port communication.
