The following connectors with built-in terminating resistors are also available.
A Terminating Resistor can be connected to a T-branch Connector.

1. Standard thin DeviceNet cable is used for cables with shielded connectors,
so maximum current is 3 A.
2. Multi-drop wiring cannot be used with shielded connectors. Use T-branch
wiring with DCN2-1 T-branch Connectors and cables that have shielded
connectors on both ends.
3. The T-branch Connector's communications power supply pin has a rated
current capacity of 3 A.
4. A cable with a shielded connector (socket) on one end can be used to con-
nect to a regular DCN1-@C T-branch Tap. A cable with a shielded connec-
tor (socket) on one end can also be used to connect to the communications
power supply from a T-branch Connector.

Note Tighten the connector by hand to a torque of 0.39 to 0.49 N ⋅ m. If the connec-
tor is not tightened sufficiently, it will not provide the expected environmental
resistance and may come loose from vibration. Do not use pliers or other tools
to tighten the connectors, because the tools may damage the connectors.
This section describes the node address settings and baud rate settings that
are common to all of the Environment-resistive Terminals. These settings are
made on separate switches, as shown in the following diagrams.
