Wire the Connector for the AutoMax Network
Use a drop cable, 612574-36R, available through Rockwell Automation Systems
Business, and passive tap M/N 57C380 to connect the module to the coaxial
network cable. This cable turns down and has a ferrite to reduce EMI. This cable
must be used in CE applications. You can also use drop cable 612403-036R but it
points up.
The drop cable is a 3-foot long multi-conductor cable with 9-pin D-shell connectors
at each end. Connect one end to the connector on the module and the other end to
the passive tap.
The passive tap has two BNC connectors for connection to the coaxial cables and
terminating loads.
The network coaxial cable must be terminated with 75 ohm terminating loads
attached to the taps at the physical ends of the network. There should be two and
only two terminators on the network.
For DCS, the network cable can be RG-59/U or RG-11/U. For remote I/O, the
cable must be RG-59/U.
