The Digi One IA serial server provides reliable, cost-effective network
connectivity for virtually any serial device. This unobtrusive and easy-to-use
device server delivers serial-to-Ethernet connectivity to Programmable Logic
Controllers (PLCs), Remote Terminal Units (RTUs), process and quality equipment,
bar-code readers and other industrial devices.
Digi One IA supports most industrial automation protocols through TCP/UDP
connections, serial bridging or COM port redirection using Digi’s patented
RealPort® software. RealPort enables existing applications to communicate,
without modification, with serial devices over the Ethernet. By creating a
Modbus bridge, multiple Modbus/TCP masters can share Modbus serial slaves, or
Modbus serial masters can access Modbus/TCP slaves.
Digi One IA serial servers are easy to install locally or remotely. The IP
address can be configured using DHCP, ARP-Ping or Setup, an application included
with the installation CD that automatically detects Digi One devices on the
network. Using the web interface, users can configure advanced functions into
their application.
