CAN Hub - no electronics inside

I think there is no resistor at all - if you look closely at this PCB, there is only a dedicated place
but there is no physical component. This would be confirmed by the diagram made by @Ronin and shown in this film.

By the way - the CAN bus needs a terminator at the beginning and end of the line. The use of a hub device in the CAN network with a linear structure makes a tree structure - it differs a bit from the rules of the CAN bus . The use of resistors in the middle of the CAN network would not make sense in my opinion.
