Devices Required in a Network Section 1-3
Note 1. It is also possible to use 10Base-T twisted-pair cable by connecting the
Ethernet Unit to a 10Base-T conversion adapter.
2. A 24-VDC power supply is required even if a 10Base-T conversion adapter
is used.
1-3-2 10Base-T Ethernet Unit
The basic configuration of a 10Base-T Ethernet System consists of one hub
to which nodes are attached in star form through twisted-pair cable.
The devices shown in the following table must be obtained to configure a net-
work using a 10Base-T Ethernet Unit, so prepare them in advance.
Recommended Hub
Coaxial cable The coaxial cable comprises the main line of the
Ethernet System.
Terminator for coaxial cable
(terminating resistance)
The Terminators connect to both ends of the coaxial
cable.

10Base-T Ethernet Unit
(CJ1W-ETN11)
The 10Base-T Ethernet Units are Communications Units
that connect a CS-series or CJ-series PCs to Ethernet
networks.
Twisted-pair cable A twisted-pair cable that connects the 10Base-T Ethernet
Unit to the hub. The twisted-pair cable must have an RJ45
Modular Connector attached to each end. Use a category
3, 4, or 5 UTP (unshielded twisted-pair) cable.
Hub A relay devices that connect multiple nodes in as star LAN.
