CANx-GND are isolated from each other. They are not tied together by the adapter cable.
Table 6:
Assignments of the cable connectors of CAN-PCI/405-B4-1C4
Note:
The CAN-GND signals of the cables of the 4-channel cable adapter "CAN-PCI/405-B4-
1C4" are connected via the wire shield if the adapter is connected to the esd
hardware. Thus the housings of the 9-pin DSUB connectors are connected to the
respective CAN-GND, because no other potential is available on these connectors.
There is no connection between the cable shield and the earth potential i.e. to the 37-
pin DSUB connector housing.
Please note that in accordance with the wiring instructions the CAN-GND signal has to
be connected to the earth potential at an appropriate position (see point 3 of the
“General Rules” at the beginning of chapter 6.).
