DMI-A0 Series
2/4 ports Industrial Serial to Ethernet Device Server
Download Data Sheet
Overview:
DMI-A0 Series is a two or four serial ports to two Ethernet ports Industrial serial server, which is an easy and reliable solution for bridging your serial based equipments to the Fast Ethernet networks. The two ports Ethernet can be used to cascade two or more DMI-A0 Series devices, which eliminates the need to connect each device server to an Ethernet switch. The serial ports support RS-232/422/485 or isolated RS-422/485, and the LAN ports support 10/100Base-TX or 100Base fiber optical.
Product Information
Features
