ATTENTION
!
Taps contain passive electronics and must be used
for the network to function properly. Other methods
of connecting to Coax trunk cable will result in
reflected energy that will disrupt communications.
IMPORTANT
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 PC connected through this cable, it
is
counted as a node and must have a unique address.
RSNetWorx and RSLinx automatically finds and
assigns a node address for you.
