Cable Guidelines

The fiber optic cable used for ControlNet communications represents a
communications transmission line in which certain characteristics
exist. The following are some general guidelines which apply to this
particular transmission line and should be adhered to in order to obtain
the best possible results.

Note that these are general rules and certain deviations may be
warranted since diverse installation and environmental concerns could
change the requirements.

Cable Type – Recommended cables as shown in Table 4.B. These
cables are available in precut, popular lengths for ease of use.

Associated Hardware – The 1786–RPA module (Table 4.C) converts
the coax cable through a CNet coax tap to up to four of the 1786–RPFS
modules. The 1786 RPFS X has two connectors to receive the 200
Micron cable. The Drive ControlNet adapter board also has two
connectors to receive the 200 Micron cable.
