The Global Cache IR Extender allows you to control networked digital equipment with an IR remote control. Designed for use in conjunction with a Global Cache IR Receiver (GCRG1, sold separately), the IR Extender plugs into a computer and converts IR commands from a remote control into digital signals. Digital signals can then be recorded, played back, and used to initiate actions across the network. The IR Extender plugs into your PC at the serial port, or into a USB port with a USB to Serial Cable (sold separately). Your IR Receiver plugs into the extender's 3.5mm jack. Power is supplied to the extender by the RTS line of the serial port. Once setup, the receiver captures IR commands and the extender converts the information into serial ASCII text, which is sent to the Windows Hyper Terminal. FEATURES: Supports the full IR spectrum (30KHz to 500KHz). Filters and measures IR noise. Sends digitized signals across the network. NOTE: Requires a compatible IR receiver, sold separately. The GCRG1 receiver is recommended.
