ETHERNET INTERFACE
The Amplifiers have an Ethernet Interface. All amplifier functions can be controlled by coded
messages sent over the interface bus via RJ-45 connector on the rear panel of the unit.
1.3.1 Description
The Ethernet Interface allows the Amplifier to communicate with and participate in a Local Area
Network using RJ-45 cable.
The
Internet protocol suite
(commonly
TCP/IP
) is the set of communications protocols that
implement the protocol stack on which the Internet and most commercial networks run. It is
named for two of the most important protocols in it: the Transmission Control Protocol (TCP)
and the Internet Protocol (IP), which were also the first two networking protocols defined.
Today's IP networking represents a synthesis of two.
TCP/IP uses four numbers to address a computer. Each computer must have a unique four
numbers address. The numbers are always between 0 and 255. Addresses are normally written as
four numbers separated by a period like this:
192.168.1.50
.
The Ethernet interface is a cable bus which runs over copper or fiber. The copper interfaces use
either a coaxial cable or differential twisted pairs. The Ethernet network is defined by IEEE 802.3
standard. Descriptions for each of the physical lines are provided below.
