Flat Cable I/II
• The two communications signal lines and the two communications power
supply lines are connected to the Master Unit, Repeater Units, and Slave
Units using Flat Cable.
• Connect the communications power supply (24 VDC) to the communica-
tions power supply connector for the Master Unit or Repeater Unit.
• A Terminating Resistor (DCN4-TM4 or DCN5-TM4) must be connected at
the end of the network.
Slave Units can also be connected in parallel by using multidrop connections.
A DCN4-MD4 Multidrop Connector is required for this.
