Connect the CX-Programmer to the RS-232C port of the CP1W-CIF01 Option
Board by XW2Z-200S-CV/500S-CV RS-232C cable.
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
Peripheral bus This is the faster mode, so it is
(toolbus) generally used for CX-Pro-
grammer connections.
• Only 1: 1 connections are
possible.
• When a CP1L-EL/EM CPU
Unit is used, the baud rate is
automatically detected by the
Support Software.
Host Link A standard protocol for host
(SYSWAY) 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.
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".

Features CPU Unit setting method
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.
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.
