What do the “HS”, “LS”, and “SWC” terms mean in Kvaser’s product titles?

HS stands for “High Speed” CAN, “LS” stands for “Low Speed” CAN, and “SWC” stand for Single Wire Channel CAN.

The majority of current applications use HS – High Speed CAN.  For more details on these different types of CAN networks, see Slide 6 of the CAN Protocol Tutorial which discusses the Physical Layers.
