Using the USB-UIRT with Vectir

If you have not installed the drivers for your USB-UIRT, please view the hardware setup topic for instructions on driver installation and testing of your USB-UIRT.

The USB-UIRT setup dialog is available under the Hardware option on the Setup panel. When the USB-UIRT setup dialog is first opened, the General tab should be visible. See below:

The Enable and Disable radio buttons enable/disable IR reception and transmission with the USB-UIRT. If the Disable radio button is 'checked', Vectir will ignore any IR received from the USB-UIRT and will not transmit any IR to the USB-UIRT.

The Capture mode on check box will put the USB-UIRT module into capture mode when checked. See the Capture Mode section below.

The Connection State LED is green when Vectir has connected to the USB-UIRT module. If Vectir was unable to connect to the USB-UIRT, this LED will be red.

The Operating State LED is green when the USB-UIRT is enabled and red when USB-UIRT is disabled. The enabled and disabled state is controlled by the Enable and Disable radio buttons.

The text box at the bottom of this dialog, is used to show IR data received from the USB-UIRT. If the USB-UIRT is connected and enabled, any IR data that is received should be displayed in this text box.
Other information relating to the USB-UIRT such as details of detected errors may be displayed here as well.

USB-UIRT Settings

The USB-UIRT settings are available from the Settings tab on the USB-UIRT setup dialog. See below:

The Blink On Receive check box controls the IR receive LED on the USB-UIRT device. If this check box is 'checked', the USB-UIRT will blink its IR receive LED when an IR command is received.

The Blink On Transmit check box controls the IR transmit LED on the USB-UIRT device. If this check box is 'checked', the USB-UIRT will blink its IR transmit LED when an IR command is transmitted.

The Transmit repeat count setting controls how many times an IR signal is repeated for each transmission. i.e. if this setting is 1, the IR signal will only get sent once for each transmission. If this setting is 10, the IR signal will get repeated 10 times in a row for each transmission.
This setting may need to be tuned for the device that you are attempting to transmit IR to. If the device is failing to pick up the IR signal, try increasing the transmit repeat count. If the device is receiving the IR signal too many times, try reducing the transmit repeat count.

Capture Mode

When the USB-UIRT is in capture mode, it will attempt to read enough information about a received IR signal to be able to successfully re-transmit the signal. The Capture mode on check box on the General tab turns capture mode on and off.

Please view the sending IR topic for instructions on how to use the capture mode with Vectir.
