Connecting Cables and Terminating Resistor
Section 3-4
Multidrop Connections
Using Round Cable I/II
The DCN4-TB4 Open Type Connector is used to convert the communications
connector on the Slave Unit or Repeater Unit to a terminal block (M3) for con-
necting the cable wires.
Example: Round cable I

Connection Method
1,2,3...
1.
Orient the Open Type Connector so that surface with the open terminals is
facing to the left and press in the Open Type Connector until it clicks into
place.
Note
To remove a Connector once it has been attached, press in firmly
on the latches on both sides of the Connector and pull it out.
2.
Open the terminal cover of the Open Type Connector and connect the ca-
ble wires to BDH (communications data high) and BDL (communications
data low) in the terminal block. For round cable II, connect the cable wires
to BS+ (communications power supply plus) and BS- (communications
power supply minus).
Note
Before connecting the cable wires to the terminal block, first attach the M3
crimp terminals shown below to the wires.
Using Flat Cable I
Attach a DCN4-MD4 Multidrop Connector to the communications connector of
the Slave Unit or Repeater Unit, and then attach two DCN4-BR4 Flat Connec-
tor Plugs that are already connected to Communications Cables.
