• Connect the terminals DA and DA, DB and DB as well as DG and DG of each station with shielded
twisted pair cables. Because two DA terminals and two DB terminals are provided in the FX
a next station can be easily connected.
• Connect the SLD terminal of each station to a shield of a shielded twisted pair cable.
• Perform Class 3 grounding to the FG terminal of each station.
• Wiring of each station can be performed from any point without regard to the station No.
• When the FX
