ETHERNET PROTOCOL
Ethernet is a network protocol complying with IEEE Standard
802.3. It is a CSMA/CD protocol (with no token). All devices on
the ethernet network listen to the data transmissions. When
the line is open, a device with a message to send can transmit
at a rate of up to ten megahertz. The ethernet link supports
DECnet and TCP/IP protocol.

ETHERNET CONFIGURATIONS
Follow these ethernet configuration rules closely to correctly
set up the network.
•
An ethernet message can pass through up to two repeaters
or network bridges before it reaches its destination.
•
Ethernet networks require a terminator at each end of the
cable.
•
The figures in this section are guidelines. Each network
may require changes due to hardware or application.
NOTE: Be careful using hardware from more than one manufac-
turer. Similar parts can have different specifications that can limit
performance.
