3-2-3 Connecting Communications Cables to T-branch Taps

To allow for easier maintenance, use a T-branch Tap or T-branch wiring to connect the DeviceNet
Communications Unit. This section shows how to connect a communications cable with a connector
attached to a T-branch Tap.
There are two kinds of T-branch Taps, one makes a single branch and the other makes three
branches, but the cable connections are the same for both. The connectors indicated by asterisks in
the following diagrams have the least resistance and these connectors should be used for the trunk
line connections. When using a T-branch Tap on a drop line, connect the longest drop line to these
connectors.
