Product Overview

Serial device server module is specially designed for SICOM3028GPT series, supporting 4 selectable RS232 RS422 and RS485 serial ports in 10 pin RJ50 connector, isolated IP address and management.

The enhanced version supports RTS carrier flow control, Optoelectronic isolation etc. This serial module is fully compliant with EMC level 4 with each serial port integrated with ±15KV ESD protection circuit. It enriches SICOM3028GPT series with standard serial device server functionalities for utility applications. 

Key Features
