ON - DAU LPBus if the last device in line
OFF - Other devices are connected to DAU apart from DCP
CONNECTION TO CANBUS
When installing a DAU connect the unit or the CAN Bus Splitter to J8 using a 4-core cable (a CAN
Bus Splitter is required when a DCP is supporting more than one lift). Please note that if the
device is wired incorrectly, the DAU will not work.
• If only the DAU is connected to the DCP set SW1:4 to ON (default setting) on both, as these
devices are End of Line.
• If the DAU is an intermediate device between the DCP and another CAN device, set SW1:4 on
the DAU to OFF.
• The use of shielded twisted pair cables is recommended.
