Overview
Twisted-pair Cable or Optical Fiber Cable Connection
Communications between Different PCs
The Controller Link Units can be connected to the network using either shielded
twisted-pair cables, optical fiber cables, or optical ring optical fiber cables. The
optical ring optical fiber cables can be either H-PCF cables or GI cables. Select
the system that suits the application.
Features of Twisted-pair Cable
Twisted-pair cable is easy to connect and maintain. The cable can be processed
much more easily than coaxial or optical cable, thereby reducing the cost of tools
and assembly time.
Connections are made to a terminal block on the Controller Link Unit and to a
special connector on the computer board for easy system assembly and modifi-
cation.
The network is equipped with the required terminating resistance built into the
Units allowing the terminating resistance to be easily set at both ends of the net-
work using a simple switch.
Features of Optical and Optical Ring Systems
Optical fiber cable (H-PCF cable or GI cable) has superior noise resistance, so
the system can provide highly reliable communications even in very noisy condi-
tions.
With H-PCF cable, the total communications distance can be up to 20 km (1 km
max. between nodes using adhesive polishing). With GI cable, the communica-
tions distance can be up to 30 km (2 km max. between nodes using 62.5/125 µm
cable), which allows long-distance and large-scale networks.
Once the optical fiber cable has been fitted with special connectors, the cables
can be easily connected or disconnected.
The following Controller Link Units are available for communications between
different PCs. Wired Units and Optical Units, however, cannot be used together
in the same Controller Link Network. (Optical and Optical Ring Units can exist in
one Controller Link Network using H-PCF cables, but with GI cables, on an Opti-
cal Ring Unit is available.)
