Connection method
For CPU Units manufactured from July
1995 onward (lot No. jj75), the stipulated
values in the DIP switch settings also are
9600 bps and 2 stop bits.
Set this to RS-422A.

SW3) Set SW3 to OFF.
(DIP SW4)
Set this switch to ON.
(Set terminator ON.)
To effect the values set in the PLC
Setup, set SW4 to OFF.
To effect the existing DIP switch
settings, set SW4 to ON.
Note
For CPU Units manufactured before or
during June 1995 (lot No. jj65), the
existing DIP switch settings differ from
the PLC Setup default values as follows.
- Existing DIP switch settings:
- PLC Setup default values:
2,400 bps, 1 stop bit, even parity, 7 bit
