Connecting to a Network

This chapter contains information on how to:
• Test your system with a T-connector and loopback connector.
• Connect to a ThinWire Ethernet or standard Ethernet network.
• Connect several systems together to create a simple ThinWire

Ethernet work group.

To form a work group, you connect systems together sequentially with

cables and connectors.
Connecting a system to a ThinWire Ethernet network or a Standard

Ethernet network takes only a few minutes for an experienced user,

slightly longer for a new user.

A Brief Introduction to Networks

Networks allow people to work together on projects and share information.

They can communicate and exchange information, share common

databases, share files and disk storage, share printers, or use a mail

system. Digital networks lets users perform all of these functions.
For network installation instructions, go to the next section, ‘‘Connecting

to a ThinWire Ethernet Network’’. For users who want more background,

here are a few networking definitions to help you get started:

Networking Terms

Network

A group of computers, connected by communications lines, that share

information and resources. A network can span a small office, a

department, a building, a country, or the world. Digital hardware and

DECnet software enable computers to form a network.
