Term
Description
multi-master
Any configuration in which more than one master
simultaneously communicates with a slave.
protocol request
A message generated by the master and sent to
the slave that requests information or issues a
command protocol response a message
generated by the slave in response to a protocol
request from the master.
slave (or protocol slave)
The device that responds to requests from the
master.
TCP socket (or TCP socket service)
A type of network service that uses TCP to
ensure reliability. When this guide discusses TCP
sockets, it means that IA protocol messages are
encapsulated in network packets and
transported across the network using a standard
network service. Many applications support
connections to devices using TCP socket.
TCP tunnel
A TCP socket connection in which a master is
connected to the serial port of one device and a
slave to the serial port of another device.
RealPort
UDP sockets (or UDP socket service) similar to
TCP socket service (discussed above) except that
the UDP protocol is used instead of TCP, which
means that the reliability service TCP performs is
not provided. Advantages of UDP socket service
are slightly less protocol overhead and support
for multicasting. Some applications support
connections to devices using TCP socket.
UDP tunnel
A UDP socket configuration in which a master is
connected to the serial port of one device and a
slave to the serial port of another device.
Serial bridge profile: master and slave connected to Digi ports
Use the Serial Bridge profile to connect a protocol master to the serial port of one device server and
the protocol slave (or slaves) to the serial port of another device server. This profile, which is often
called a serial bridge, is applicable to environments that use most IA serial port protocols and to multi-
master environments as well. The network is completely transparent to the serial devices, which
means they do not have to be reconfigured.
