6-14 Terminal Connections
DHPlus Network Connections
Use the Belden 9463 twin axial cable (1770-CD) to connect a
PanelView Plus terminal to the DH+ link.
You can connect a DH+ link in 2 ways:
• trunk line/drop line - from the drop line to the connector screw
terminals on the DH+ connectors of the processor
• daisy chain - to the connector screw terminals on the DH+
connectors on the processor
Follow these guidelines when installing DH+ communication links:
• do not exceed these cable lengths:
– trunk line-cable length: 3,048 m (10,000 ft)
– drop-cable length: 30.4 m (100 ft)
The maximum cable length is determined by baud rate.
• do not connect more than 64 stations on a single DH+ link
