Kramer TP-573 Video Extender

The Kramer TP-573 Video Extender is a robust twisted pair transmitter designed to move HDMI video, bi-directional RS-232, and infrared (IR) control signals over a single twisted-pair link. When used in concert with the TP-574 receiver, it unlocks flexible, long-distance distribution of high-definition content and remote control capabilities across conference rooms, classrooms, or home theater setups. This transmitter converts HDMI input and control data into a resilient twisted pair format, enabling you to locate your source far from the display while preserving signal integrity and control fidelity. Whether you’re upgrading an existing AV installation or planning a new build, the TP-573 TP-574 pair offers a compact, reliable solution that minimizes cable clutter without compromising performance. Built with Kramer’s engineering heritage, the TP-573 emphasizes ease of integration, dependable operation, and straightforward deployment so technicians and end-users alike can focus on content rather than cables.

• HDMI, RS-232, and IR over twisted pair: The TP-573 is a dedicated transmitter that carries high-quality HDMI video and audio along with bi-directional RS-232 data and infrared control signals over a single twisted-pair link. This enables a centralized source to control distant displays and connected devices while delivering pristine video, making it ideal for boardrooms and classrooms where centralized control is essential.
• Bi-directional RS-232 and IR support: By supporting two-way RS-232 and IR communications, the extender preserves full control of connected equipment at the display end. This allows remote devices to respond to commands from the source side and enables IR-based remote control from the display location, improving usability in complex AV setups where line-of-sight is limited or where centralized control is preferred.
• Seamless pairing with TP-574 receiver: The TP-573 transmitter is designed to work in tandem with Kramer TP-574 receivers to complete the HDMI extension. The paired system delivers a complete transport path for HDMI, RS-232, and IR signals, enabling dependable distribution across the desired distance and simplifying system design by using a single infrastructure for both video and control signals.
• Plug-and-play installation with standard twisted-pair cabling: The unit is optimized for quick deployment with standard twisted-pair cabling. Simply connect the TP-573 to your HDMI source and connect the TP-574 at the destination display or display cluster, then run a single twisted-pair link between the two units. The design prioritizes compatibility with existing cabling in corporate environments, education spaces, and home theater installations, reducing setup time and potential misconfigurations.
• Professional-grade reliability for scalable AV distributions: Engineered for demanding environments, the TP-573 and TP-574 combination delivers stable performance even as systems scale. Their compact footprint, solid build, and straightforward operation support multi-room installations, centralized control architectures, and future upgrades without sacrificing signal quality or reliability.

how to install Kramer TP-573 Video Extender

• Step 1: Connect your HDMI source to the TP-573 input. If you are using RS-232 or IR control, connect the devices to the respective RS-232 and IR ports on the transmitter according to your control architecture.
• Step 2: Place the TP-574 receiver at the display or display cluster location and connect its HDMI output to the display’s HDMI input. Also connect the RS-232 and IR outputs on the TP-574 to the controlled devices or displays as required.
• Step 3: Run a single twisted-pair cable between the TP-573 transmitter and the TP-574 receiver. Ensure the cable is appropriately rated for your environment and that the connections are secure to maintain signal integrity.
• Step 4: Power both the transmitter and receiver from their respective power supplies. Verify that both units are powered and showing normal status indicators as per the user guide.
• Step 5: Configure the HDMI source for the target display and test the RS-232 control path and IR remote control. Confirm that video, audio, and control commands travel correctly across the extender, and adjust IR emitter placement if needed to optimize remote sensing.

Frequently asked questions

• What signals does the Kramer TP-573 transmit? It transmits HDMI video (and audio), bi-directional RS-232 data, and infrared control signals, over a twisted-pair link when used with the TP-574 receiver.
• Do I need a TP-574 receiver to use the TP-573? Yes. The TP-573 is the transmitter component and requires the TP-574 receiver to complete the extension path and restore HDMI, RS-232, and IR signals at the display end.
• Can RS-232 be controlled in both directions? The system supports bi-directional RS-232 communication, enabling control commands to flow between the source and the display or remote devices as part of the extender pair.
• Is IR control supported across the distance? Yes, IR signals can be transmitted from the source side to the display side and, depending on setup, can return control information via the extender pairing.
• Is the TP-573 suitable for professional AV installations? Yes. The design targets reliable performance in corporate, educational, and high-end home theater environments where centralized control and long cable runs are common requirements.
