To use the USB function, it is required to install the driver on the PC. Follow these steps to
install the driver:
1. Download and install the USB Driver from the
website
.
2. Click
Install
to install the drivers. When the installation is complete, this message will
appear:
Install Successfully.
3. Click
Exit
to close the dialog box and restart the PC.
To verify the drivers are installed correctly, go to Windows
Device Manager
after restarting
the PC. Expanding the
Ports
field, you should see
XR21B1411 USB UART
. The COM
number in the parenthesis indicates the COM port currently in use.
Note:
If you unplug the GV-I/O Box 16 Ports from the PC and connect another GV-I/O
Box to the same USB port, the COM port may still be changed. Access the Windows
Device Manager
again to look up the new COM port number.
