Chapter 4 Maintenance
Twisted-Pair Cable
Caution :
Careful selection of proper cable is essential to obtain the best performance.
Vicon assumes no responsibility for poor performance when cables other
than the recommended types, or equivalent, are used.
Materials
Use a pure copper stranded conductor with or without a tin-plating to obtain a
low DC resistance. Do not use cable with either steel or aluminum stranded
conductor because they do not transfer signals effectively for long distances.
The preferred insulation and cable jacket is Polyvinyl chloride (PVC). It has
better electrical characteristics than polyethylene and resists flames, sunlight
and most solvents, but is more vulnerable to moisture.
Cable Types
The most commonly used cable types are dual individually-shielded, twisted
pair in a single jacket. This configuration is the most convenient for RS-422/
RS485 applications. Single individually-shielded, twisted pair is also a
suitable cable.
Choose a Belden® cable type by referring to the characteristics and
maximum distances listed below. The maximum distance for the most
reliable digital control refers to the distance between the unit and the receiver
or camera dome unit. The characteristics of the cables should be used as a
guideline when cables other than Belden are used. Materials and
construction must follow the guidelines above.
