IR Blaster, along with Automation Software such as SnapStream Beyond TV, allows your PC to both Receive and Transmit infrared signals -- exactly like those used by the collection of remote controls you've acquired for your TV, VCR, Audio System, etc.Receive signals from the remote controls you already have (allowing your PC to perform actions when the 'Play' button is pressed on your VCR remote, for example)'Learn' from remotes you already have and Transmit a duplicate of these signals from your PC (for example, your PC could automatically turn ON your VCR and tune it to channel 3) - Use codes available from the Web for other remotes (such as the Philips Pronto) to control all of your equipment with Remote (IR) receivers (including special 'discrete' remote codes your brand-name remote doesn't include). For example, IR Blaster could transmit the discrete 'Input 3' code to your TV to directly switch it to input 3, rather than cycling through all of the inputs.Software DOWNLOAD http://www.kinamax.com/drivers/IR-BLSTR.zip.IR Blaster contains a small micro-controller which is capable of 'listening' for Infrared codes which are transmitted from most remote controls. When IR signals are detected, the IR Blaster interprets these signals, decodes them, and sends them to your PC via a USB connection. Automation Software such as Girder can be programmed to respond to these codes. In addition, software on the PC can send IR codes to IR Blaster to be transmitted. IR Blaster's microcontroller will translate these codes to an Infrared stream and transmit them using built-in IR emitters or a connected IR extension.
