n
address)

Advanced Digi Discovery Protocol (ADDP)
The ADDP runs on any operating system capable of sending multicast IP packets on a network. ADDP
allows the system to identify all ADDP-enabled Digi Connect and ConnectPort TS Family products
attached to a network by sending out a multicast packet. The Digi Connect and ConnectPort TS
Family products respond to the multicast packet and identify themselves to the client sending the
multicast.
ADDP communicates with the IP stack using UDP. The IP stack can receive multicast packets and
transmit datagrams on a network.
You can enable or disable access to ADDP service, but you cannot change the network port number for
ADDP from its default.

RealPort software

Digi's RealPort software leverages the TCP/IP network infrastructure to provide a virtual connection
to serial devices. The software is installed directly on the server and allows applications to talk to
devices via a Digi device server or terminal server over a network.
RealPort software is a COM port redirector that allows multiple connections to multiple ports over a
single TCP/IP connection. This means RealPort supports the maximum number of remote devices. The
number is restricted only by the operating system and server processing power.
