Twisted-Pair Cable
CAUTION: Careful selection of the proper cable is essential to obtain the best performance from this
equipment. Vicon assumes no responsibility for poor performance when cables other than
those recommended are installed.
t Ma erials
Use a pure copper stranded conductor with or without a tin plating to obtain a low DC resistance. Do not use cable with
ither a steel or an aluminum stranded conductor because these do not transfer signals effectively e
p for long distances. The
referred insulation and cable jacket is Polyvinyl chloride (PVC). It has better electrical characteristics than polyethylene
ir in a single jacket. This configuration is
the most convenient for RS-422/ RS485 applications. Single twisted pair is also a suitable cable.

Cable Types
The most commonly used cable types are dual individually-shielded, twisted pa

Assembly. The characteristics of the cables in Table 6 should be used as a guideline when cables other than Belden are
used. Materials and construction must follow the guidelines above.
