Make DH+ Connections
Use the Belden 9463 twin axial cable (1770-CD) to connect a DH+
InView communication module 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 cable ft)
– Drop-cable length: 30.4 m (100 cable ft)
• Do not connect more than 64 stations on a single DH+ link
