3.4 CAN/DeviceNet Unit

3.4.1 General

The CPCI-405 has got two independent CAN-channels. Each of these CAN-channels has got its own
SJA1000 controller. 

CAN-channel  CAN0  can  be  accessed  via  9-pin  DSUB  connector  X1000  in  the  front  panel.  An
82C250/82C251 is used as driver unit. The differential CAN-bus signals are electrically insulated from
other potentials.

The signals of CAN-channel CAN1 are at post connector X1010 in the form of TTL-signals. The TTL-
signals of CAN0 are also led to this connector. By means of a flat ribbon cable two adapter boards can
be connected to X1010. These adapter boards are available with the physical layer for CAN (ISO11898
with DSUB-connector), or with the physical layer for DeviceNet (Combicon socket). The flat ribbon
cable  for  the  connection  of  adapter  boards  can  be  fed  through  from  one  board  to  the  next.  This
minimizes the wiring within the case.

Note: If the option of the external CAN or DeviceNet interface is used for CAN-channel CAN0

via the adapter board, the local CAN-interface cannot be used anymore, because it would
require a change in the equipping!
