Wiring Methods
!Caution To avoid damaging the cable or breaking wires, leave some slack in the cable
Note Use the DeviceNet cable for the connection to the DRS1-T Terminal-block Ter-
This example shows a DCN2-1 T-branch Connector, but the connection
method is the same for other T-branch Connectors.
Connecting to a Terminal Block
When a node is connected directly to the end of the trunk line and there isn’t
enough space to connect a T-branch Tap, a Terminal-block Terminating Resis-
tor can be connected with a multi-drop.
A 121 Ω terminating resistor is built into the DRS1-T Terminal-block Terminat-
ing Resistor. To connect the cable to the Terminating Resistor, attach crimp
terminals to the signal wires and securely screw the terminals to the Terminal-
block Terminating Resistor.
minating Resistor and keep the cable length less than 1 m.
Use standard M3 crimp terminals and tighten to a torque of between 0.3 and
0.5 N ⋅ m.
so that it won’t be pulled too hard or bent too sharply when connecting. Also,
never put heavy objects on top of the cable.
Flat Cable
Attach a DCN4-TM4 Terminating Resistor to the DCN4-TR4-1 Flat Connector
Socket connected to Communications Cable.
