Incorrect info regarding CAN connections

I was trying to set a RoboCAN with 2 nodes. I was told to check out this article( link ). In the article, it says pins 8 and 20 in the 25pin port are set as CAN_L and CAN_H in roboteq devices. I read this and did the connections accordingly which is why i believe i couldn't detect the second node as the CAN_L and CAN_H are different in different roboteq devices. See the attached files for reference.
