1)
The interfaces, etc. available on the device or module have been numbered 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 automatically enabled in BIOS as CAN with default addresses I/O: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 transfer rate. According to CAN in Automation (CiA), the maximum bus length is 1000 meters.
The following bus lengths are permitted at a maximum permissible oscillator tolerance of 0.121%:
