1) The interfaces, etc. available on the device or module have been numbered as such for the purpose of clear differentiation. This numbering may deviate
from the numbering used by the respective operating system, however.
2) This interface (if available) is enabled automatically in BIOS as CAN with default I/O address 384h/385h and IRQ 10.

CAN - Bus length and cable type
The type of cable to be used depends largely on the required bus length and number of nodes. The bus length is
determined by the bit rate. In accordance with CiA (CAN in Automation), the maximum bus length is 1000 meters.
The following bus lengths are permitted with a maximum oscillator tolerance of 0.121%:
