How do I wire to get 120 ohm termination?

[size=14.6667px]I want to confirm wiring for Ginkgo USB-CAN interface. I get the H,L, and G wiring, but for R I’m not clear. Do I connect to R when I want 120 ohm termination (instead of L)? How do I wire to get 120 ohm termination? I have only CAN hi and lo wires from network.

   Yes, the usage of R is:
   1. If need an internal 120 ohm resistance, then do connect R with L, and using H and L to connect CAN bus H and L with other CAN devices;
   2. If do not need an internal 120 ohm resistance, then do nothing with R, leave it there, and using H and L to connect CAN bus H and L with other CAN devices;
   One other way to get 120 ohm resistance is: open the box, connect internal jumper which get the same results as R connection with L;
