Wiring Flat Cable I or II
• Flat Cables are used as the two communications signal lines and the two
communications power supply lines that connect the Master Board or a
Repeater Unit with the Slave Units.
• A 24-VDC communications power supply is connected to the
communications power supply connector on the Master Board or
Repeater Unit.
• At the end of the network line, there must be a DCN4-TM4 Terminating
Resistor attached with a DCN4-TR4 Flat Connector I Socket.
When Flat Cable I is used, Slave Units can be connected in parallel also by
multidrop connections. A DCN4-MD4 Multidrop Connector is used for this
connection.
