When you use the RJ-45 connector, you can connect the card to a ControlNet
network without a tap through the Network Access Port (or NAP) of a
programmable controller, I/O adapter, or other ControlNet compliant devices
(Figure 3 and Figure 4).

ATTENTION
!
If you connect the product to a cable system that does not
support redundant media, connect the tap dropline to the BNC
connector labeled channel A. Channel B is left open.
If the cable system is redundant, connect the product so that
all devices on the network use the same cable for the same
channel. That is, all channel A connectors connect to one
cable; all channel B connectors connect to the other.

The 1786-CP cable can be plugged into any ControlNet product’s NAP to provide programming
capability on the ControlNet network. When you connect a programming terminal through this
cable, it is counted as a node and must have a unique address.
