Connection Methods

A CJ2 CPU Unit can be directly connected to a personal computer running the CX-One Support Soft-
ware (e.g., CX-Programmer) by using a USB cable or RS-232C cable. (The CP1W-CIF01 is required to
use a RS-232C cable with the CJ2M-CPU3@.) Also, an Ethernet twisted-pair cable can be used for the
CJ2H-CPU6@-EIP or CJ2M-CPU3@.

Before Connecting

In order to connect the PLC to a personal computer by USB, a USB driver must be installed in the per-
sonal computer. The USB driver for USB connections is automatically stored in the following directory in
the personal computer when CX-One is installed:
C:\Program Files\OMRON\CX-Server\USB\Win2000_XP\inf
When the personal computer is connected to the PLC by USB cable, the personal computer automati-
cally recognizes the device and the USB driver installation is started. For details on how to install the
USB driver, refer to A-5 Installing the USB Driver.
