Cabling Requirements for NI 9852
This section deals with cabling specifications, termination
resistors, cable lengths, and the number of CAN nodes that can
exist in a system.
Cable Specifications
Cables should meet the physical medium requirements specified in
ISO 11898, shown in Table 3. Belden cable (3084A) meets all of
those requirements, and should be suitable for most applications.
