Connecting Programming Devices
Section 1-3
Connection Method
Connect the Programming Device using the Connecting Cable that is appro-
priate for the serial communications mode of the computer and CPU Unit.
Serial Communications Mode
Note
When a Serial Communications Option Board is mounted in Option Board
Slot 1, it is called “Serial Port 1.” When mounted in Option Board Slot 2, it is
called “Serial Port 2.”

CPU Unit setting method
Peripheral bus
(toolbus)
This is the faster mode, so it is
generally used for CX-Pro-
grammer connections.
• Only 1: 1 connections are
possible.
• When a CP1H CPU Unit is
used, the baud rate is auto-
matically detected by the Sup-
port Software.
Turn ON pins SW4 (Serial Port
1) and SW5 (Serial Port 2) on
the DIP switch on the front
panel of the CPU Unit. These
settings enable connection by
peripheral bus regardless of the
serial port settings in the PLC
Setup.
Host Link
(SYSWAY)
A standard protocol for host
computers with either 1: 1 or 1:
N connections.
• Slower than the peripheral
bus mode.
• Allows modem or optical
adapter connections, or long-
distance or 1: N connections
using RS-422A/485.
Turn OFF pins SW4 (Serial Port
1) and SW5 (Serial Port 2) on
the DIP switch on the front
panel of the CPU Unit.
The mode will then be deter-
mined by the serial port set-
tings in the PLC Setup. The
default settings are for Host
Link with a baud rate of 9,600
bits/s, 1 start bit, data length of
7 bits, even parity, and 2 stop
bits.
