7 CAN Connection
C-PRO GIGA can be connected to other controllers, to expansion modules and to one or more user
interfaces using either local or wide CAN serial port. The CAN bus uses the ISO 11898 standard, a
balanced two-wire communication very similar to the RS-485 standard.
Resistors with a recommended rating of 120-124 ohm have to be fitted at each end of the bus.
If connection is established through the local CAN bus, it is possible to power a user interface
terminal by using the 4-terminal connector, according to the following table:
C-PRO GIGA V-VIEW User Interface
YA 1 (VDC ) PA 1 (VDC )
YA 2 (CAN+) PA 2 (CAN+)
YA 3 (CAN-) PA 3 (CAN-)
YA 4 (GND ) PA 4 (GND )
The maximum number of expansions and user terminals is 32.
The maximum number of controllers for the user terminal V-VIEW is 2.
