Note2: Roughly speaking, wiring of CAN_GND and FG can improve the
capability of anti-interference of CAN bus system in harsh
environment, but this is not necessary.
Note3: When users want to calculate the total bus line length, i-7531
need also be considered.
According recommended specific line delay 5ns/m, one i-7531
(~200ns delay) should be considered as one 40m bus line.
For more information, please refer to the user manual of i-7531.
