Mounting Terminating Resistors Section 5-3
The multi-drop wiring connector cannot be used with Master Units if it will
come in contact with Units mounted next to the Master Unit. Use a T-branch
Tap to wire the connection instead.
5-3 Mounting Terminating Resistors
Terminating Resistors must be used at both ends of the trunk line.
A Terminating Resistor is either connected to a T-branch Tap or a Terminal-
block Terminating Resistor is connected to a communications cable extended
from a node.
T-branch Tap
Terminating Resistors
Terminating Resistors are included with the T-branch Tap.
Insert the Terminating Resistor into the T-branch Tap, as shown in the follow-
ing diagram. The Terminating Resistor can face either direction.
Terminal-block
Terminating Resistors
The DRS1-T Terminal Block has a built-in Terminating Resistor. Attach crimp
terminals to the communications cable in the same way as connecting a stan-
dard terminal block, and securely screw the terminals to the Terminal-block
Terminating Resistor.
Use M3 crimp terminals for the signal wires.
Tighten the screws to a torque of 0.3 to 0.5 N·m.
5-4 Maintenance Information Window
This section describes the Maintenance Information Window, which can be
used to check the status of various general-purpose Slaves. The Monitor
Device Window can be used to check the same Slave status information, but
the examples in this section uses the Maintenance Information Window. Refer
to 4-1-2 Maintenance Mode Window for details on the differences between
the Maintenance Information Window and the Monitor Device Window.
