• Remote and local control: IR in/out support and RS-232 provide flexible control over the source device from remote locations, which is essential for classrooms, hospitality suites, and conference venues.
• Latency: Engineered for near-zero latency to preserve real-time interaction in live presentations and multi-display setups, ensuring lip-sync and timing remain intact across all connected displays.
• Physical and configuration features: Includes a DIP switch and multiple reset buttons for straightforward configuration, troubleshooting, and quick reconfiguration during installations. The rugged design is suited for rack-mount or AV cabinet deployments.
• Compatibility: Ideal for professional AV ecosystems where a single source must be reliably shared across several displays, signage panels, or projectors, with additional control pathways via RS-232 and IR for turnkey operation.

How to install SIIG 1x2 4K60Hz HDMI Splitter Over Cat6 Extender

• Begin by connecting your HDMI source to the HDMI input on the splitter. Ensure the source device is configured for 4K60Hz output if supported, and set the source resolution to a compatible format to maximize compatibility with all connected displays.
• Connect the HDMI loop-out from the splitter to a local display. This enables a direct feed to a monitor in the same room while the remaining displays receive the same signal via Cat6 extenders.
• Run separate Cat6 Ethernet cables from the splitter’s RJ45 ports to each remote display or extender location. Cat6 is recommended for optimal bandwidth and signal integrity at longer distances. Ensure cables are properly terminated and meet the required network standards for AV transmission.
• Attach your HDMI cables from the remote displays to the HDMI outputs of the extender or receiver unit. Confirm each display is set to the correct input source to receive the distribution from the splitter.
• Configure the built-in DIP switch according to the installation guide to match your setup (1x2 distribution, distance, and any alignment of IR/RS-232 control). Use the reset buttons if you need to restore factory defaults during the initial setup or troubleshooting. Finally, connect the IR emitters/receivers and RS-232 connection as needed for control and automation. Power up the system and verify synchronization across all displays; adjust input resolution or EDID settings if available to achieve optimal image quality.

Frequently asked questions

• What is the maximum distance for HDMI extension? Up to 230 ft (70 m) when using standard Cat6 cabling. Distance can vary with cable quality and environmental factors, so it’s recommended to test in the final installation space.
• Does this splitter support 4K at 60 Hz? Yes. The device is designed to distribute 4K60Hz video across two outputs with loop-out capabilities, making it suitable for modern 4K displays and presentations.
• How many displays can be driven simultaneously? The unit supports two HDMI outputs, allowing two remote displays (in addition to the local loop-out display) to show the same source content at the same time.
• Are there audio options beyond HDMI? Yes. The system includes two S/PDIF ports for digital audio distribution, enabling synchronized multi-room or multi-zone audio alongside the video signal.
• What control options are available? The setup includes IR in/out ports for remote control of the source from the displays and an RS-232 terminal block for integration with professional automation systems, making it easy to incorporate into existing room control ecosystems.
• Is setup complicated? While the unit offers advanced features for AV professionals, the basic 1x2 distribution, loop-out, and simple DIP switch configuration are designed to be straightforward. A typical installation involves wiring HDMI cables, Cat6 extenders, loading the source, and confirming display alignment, with the RS-232 and IR controls added for automation and convenience.
