DG-A6
8 and 16-port RS232/422/485 terminal servers with multiple LAN access
Product Overview

DG-A6 series terminal server is an industrial designed 1U 19" rack-mount device. It provides full network access ability with its independent 2 giga Ethernet ports and 4 10/100M Ethernet ports. Each Ethernet port can be mapped freely to access indicated serial port. Furthermore, multiple network clients can transparently concurrent access specified serial port for redundancy.

It is important to support back-up power supply in industrial environment. DG-A6 series terminal server can also support dual AC power inputs by internally using independent power modules for extra reliability.
