Product Overview
The tvONE HD-One DX500 Transmitter (2211121-01) is the transmit-side unit of the HD-One DX500 extension system, sending HDMI 1.4 video and embedded audio over Cat5e or Cat6 cable to the DX500 Receiver at distances up to 500 feet (150 meters). This unit is sold individually and pairs with the HD-One DX500 Receiver (2211122-01). Both units are also available as a complete kit (2211114-02).
Product Description

The HD-One DX500 Transmitter accepts an HDMI 1.4 input from the source device and converts the video and audio signal for Cat5e/6 transmission to the DX500 Receiver up to 500 feet (150 meters) away. As a DX-series device, it carries video and audio only — no IR or RS232 control pass-through — making it a cost-focused choice for applications where source control at the display is not required. The compact unit is designed for installation near the source in an AV rack or equipment room. Pair with the HD-One DX500 Receiver (2211122-01) to complete the extension link. For installations requiring IR and RS232 control, the LX500 Transmitter (2211123-01) provides the same 500ft range with added control signals.
