Publication

1756-IN604A-EN-P - February 2006

The 1786-CP cable can be plugged into any ControlNet network product’s
network access port (NAP) to provide programming capability on the
ControlNet network. A programming terminal connected through this cable
is counted as a node and must have a unique network address.

Troubleshoot the Module

The 1756-CNB and 1756-CNBR modules have the diagnostic indicators as
shown:

ATTENTION

Use a 1786-CP cable when connecting a programming terminal to the
network through network access port (NAP). Using a commercially
available RJ-style cable could result in network failure.
