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.
1 The 9904-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.
