2.
The final axis must be terminated between RDP (pin No. 3) and RDN (pin No. 6) on the receiving side (driver) with a 150
Ω resistor.
3.
The overall length is 30 m or less in low-noise environment.
4.
The wiring between the branch connector and driver should be as short as possible.
5.
Use the EIA568-compliant cable (10BASE-T cable, etc.).
