Wake

Configure USB-UIRT device

The USB-UIRT is able to wake-up your computer from sleep if you set it up to do so. The USB-UIRT can recognize up to four IR codes that will wake-up you computer, these IR codes must be programmed into the flash memory of the USB-UIRT.

Using the USB-UIRT Learn Helper Utility, go into the File / Wake-Up Configuration menu, this will open the Wake-Up configuration dialog:

lrnhelper

In this dialog choose a Wake-up IR Slot then click on the Learn button and press the button on your remote you want to use to wake-up your PC. Once the code is learned, click on the Program Flash button.

Note: If you remote do send two different IR codes each time you press on a button, you'll have to learn two IR codes (one in slot 1, the other in slot 2) for waking up your PC.
