21-3. RS-232C
Basically, a single axis of servo amplifier (1:1 communication) is operated.
Multiple axes of servo amplifier (1:N communication) can be operated by RS-232C extension pins.
Cable length is 10m max. in environment of little noise.
Cable length is 5m max. in environment of 4800bps or more.
Use a twisted-pair shield cable to minimize the influence of electromagnetic interference.

21-4. RS-422
Basically, multiple axes of servo amplifier (1:N communication) can be operated.
Up to 32 devices can be connected to a single bus.
Up to 255 devices can be connected to a extended single bus by bus repeater.
Cable length is 30m max. in environment of little noise.
Use a twisted-pair shield cable to minimize the influence of electromagnetic interference.
When master station is personal computer, RS-232C/RS-422 converter is needed.
The converter must be an isolated type to minimize the influence of electromagnetic interference.
Terminal resistor (RT: 120 , 0.5W) should be connected across RDP-RDN of converter.
Ω
At the last servo amplifier, terminal resistor (RT: 120 , 0.5W) should be connected across RDP-RDN
Ω
of connector.
