Precautions for Correct Use
• The maximum length between nodes is 100 m. However, some cables are specified for less
than 100 m. Generally speaking, if the conductors are twisted wire rather than solid wire,
transmission performance will be lower, and reliable communications may not be possible at
100 m. Confirm details with the cable manufacturer.
• When selecting a connector, confirm that it is applicable to the cable that will be used. Con-
firm the following items: Conductor size, conductor type (solid wire or twisted wire), number
of twisted pairs (2 or 4), outer diameter, etc.
• Use only the specified communication cables.
