* Fix a cable so that a communication connector may be not taken the weight of wire.
3.7. Network configuration
Make up the network as follows.
- Transmission/reception signals (CAN_H, CAN_L)
Make up the communication path by connecting twisted cables with shield.
- Signal common (CAN_GND)
GND is the signal common.
- Grounding the shield of cable (CAN_SHLD)
Connect the all shield lines of network cable. The shield shall be grounded at one end only prevent currents
from being created.
- Termination resistor
A termination resistance of 120 ohms plus or minus 5% shall be connected at each of the two ends of the
segment medium.
