Use the 3-pin connector on the processor to connect a DH+ link.
The connector’s port must be configured to support a DH+
communication link.
You can connect a DH+ link two ways:
•
trunkline/dropline—from the dropline to the connector screw
terminals on the DH+ connectors of the processor
•
daisychain—to the connector screw terminals on the DH+
connectors of the processor
To make connections:
1. Connect the signal conductor with CLEAR insulation to the
3-pin connector terminal 1 at each end of each cable segment.
2. Connect the SHIELD drain wire to the 3-pin connector SH
terminal at both ends of each cable segment.
3. Connect the signal conductor with BLUE insulation to the 3-pin
connector terminal 2 at each end of each cable segment.
For more information, see the Data Highway/Data Highway
Plus/Data Highway II/Data Highway 485 Cable Installation Manual,
publication 1770-6.2.2.
