Digi One IA
Compact Serial-to-Ethernet Connectivity with Protocol Conversion and Modbus
Switch Selectable Expansion for Asynchronous Connectivity, Protocol Conversion, and Modbus
The Digi One IA is a Switch Selectable Expansion device for asynchronous connectivity, protocol conversion, and Modbus support.
Digi One IA provides reliable, cost-effective network connectivity for serial devices. This unobtrusive and easy-to-use serial server delivers serial-to-Ethernet connectivity to Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), 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 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 is 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 detects Digi One devices on the network. Using the web interface, users can configure advanced functions into their applications.
