Link Method (page 161).
Either set PLC Setup directly from a Programming Device (e.g. SYSMAC sup-
port software), or transmit the PLC Setup made at a Programming Device to
the CPU Unit.
For details on the PLC Setup, refer to the SYSMAC CVM1/CV500/1000/2000
Operation Manual: Ladder Diagrams (W202-E1-@).

Note
To effect the existing DIP switch settings,
set SW4 to ON.
To effect the existing PLC Setup, set
SW4 to OFF.
For CPUs manufactured before or during
June 1995 (lot No. @@65), the existing
DIP switch settings differ from the
existing PLC Setup as follows.
Set this to RS-232C.

For CPUs manufactured from July 1995
onward (lot No. @@75), the stipulated
values in the DIP switch settings also are
9,600 bps and 2 stop bits.
