Controlling the Product Using USB
Using the USB port and CONTROL INPUT terminal simultaneously
In remote control through the USB port, the control signal from the CN1 terminal (see the fig-
ure on the previous page) is connected to the product’s CONTROL INPUT terminal. The out-
put from the CN1 terminal is an open-collector circuit.
If you connect an open-collector circuit isolated by a photocoupler to the CONTROL INPUT
terminal, you will be able to use the USB port and the CONTROL INPUT terminal simultane-
ously.
The coil current of this product’s impedance selection relay is 100 mA or less. When the USB
port and the CONTACT INPUT terminal are used simultaneously, the CONTROL INPUT ter-
minal signal will be the logical sum of both signals. Apply a signal appropriate for the terminal
signal logic.
Installing the driver
1
Set the supplied CD-ROM (API-USBP (WDM) driver software) by CON-
TEC) in the PC’s CD drive.
2
Check that the USB cable is connected properly between the product’s
USB port and PC.
3
Turn on the POWER switch of this product.
“Found new hardware wizard” starts.
If the wizard does not start automatically, install the driver by double-clicking Setup.exe
in the “X:\INF\WDM\Dio” folder (where X is the CD-ROM drive) in the CD-ROM and
clicking “API-DIO (WDM) Installer.”
4
Select “Install the software automatically,” and click Next.
The driver installation begins.
5
When the installation is complete, click Finish.
Checking the feature
Use the CONTEC API-USBP (WDM) software supplied with the CONTEC’s DIO-0808LY-
USB Isolated Digital I/O Terminal for USB2.0, and check that the product can be controlled
through the USB port.
For details on using the diagnosis program for checking the operation, see the Isolated Digital
I/O Terminal for USB2.0 DIO-0808LY-USB User’s Guide.

CAUTION
Risk of malfunction.
• Isolate the contact signal control circuit from the internal circuit of this product with a
photocoupler, and use an open-collector circuit.
