4.4 USE OF A DIRECT DIGITAL CONTROLLER (DDC)
This paragraph describes the operations to be performed when connecting one or
more ACF60-00’s to a Direct Digital Controller (DDC). For specific information about
the DDC, refer to the manual provided with it.
ACF60-00 and DDC communicate through a CAN BUS network.
The CAN BUS network is a series of elements (ACF or DDC) called nodes, connected to
each other by a 3 wire cable. There are terminal and intermediate nodes.
The terminal nodes are ACF or DDC that are connected to only one other element.
