The CJ2 CPU Unit can be connected by USB cable, Ethernet twisted-pair cable, or RS-232C cable to a
personal computer with CX-One Support Software (e.g., CX-Programmer) installed.
Using commercially available USB cable, connect CX-One Support Software via a standard peripheral
(USB) port at the personal computer.
*1 Commercially available USB cable: 5 m max., for USB 1.1 or 2.0.
Use the following cable to connect the CJ2 CPU Unit to the computer running the Support Software.
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.
The method for connecting the PLC to the personal computer is set using the CX-Programmer. For
details on using the CX-Programmer to set the connection method, refer to the CJ2 CPU Unit Software
