Chapter 1 Introduction 9
Part of Digi’s broad device server offering, the Digi One SP delivers
standard Serial-to-Ethernet connectivity and is ideal for the following
applications:
• TCP socket and UDP socket
Socket support includes serial bridging, which requires two device
servers, each providing network connectivity for a serial device that
would otherwise be limited to communication over a serial cable.
• COM Port Redirection using Digi’s patented RealPort
software, which enables applications and serial devices to
communicate over an Ethernet network as though they were
communicating in their native serial mode over a cable.
The Digi One SP is easy to install locally or remotely through a variety of IP
addressing methods. These include DHCP, ARP-Ping, static IP, and Setup,
an application on the installation CD that automatically detects all Digi One
devices on your network.
