Publication 1768-IN006A-EN-P - September 2007
Connecting a Desktop Computer to the Network with a 1786-CP Cable
The 1786-CP cable can be connected from a desktop computer with either a
1784-PCIC or 1784-PCICS card into any ControlNet product’s network
access port (NAP) to provide access to an existing ControlNet network. A
desktop computer connected through this cable is counted as a node and
must have a unique network address (MAC ID) less than or equal to the
maximum unscheduled node (UMAX).
WARNING
The NAP is intended for temporary local-programming purposes only
and not intended for permanent connection. If you connect or
disconnect the NAP cable with power applied to this module or any
device on the network, an electrical arc can occur. This could cause an
explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
ATTENTION Use a 1786-CP cable when connecting a programming terminal to the
network through the NAP. Using a commercially available RJ-style
cable could result in network failure.
