The Lindy 70m Cat.6 HDMI 4K30 & IR Extender with PoC & Loop Out is a high-performance signal extension solution for AV professionals, installers, and system integrators. Designed to transmit HDMI and IR signals over a single Cat.6 cable up to 70 metres, it supports Ultra HD 4K resolutions at 30Hz (4:4:4 8-bit), 7.1 channel audio, and IR pass-through. With Power over Cable (PoC), only one power connection is required at the transmitter end, simplifying installation. A local loop-out port allows for local monitoring or dual-zone display configurations making this a smart, versatile choice for education, retail, business, and digital signage environments. AT A GLANCE: 70m HDMI Extension over Cat.6 with PoC - Long-distance AV transmission using low-cost cable with single PSU connection at the transmitter for simplified power management. Supports 4K@30Hz 4:4:4 8bit - Delivers crisp 4K video at 40m with accurate colour and detail ideal for professional AV applications. HDMI Loop-out on Transmitter - Enables local display for previewing, monitoring, or creating dual-zone AV setups. IR Pass-Through - Allows remote control of source devices from the display end for convenient operation. EDID Copy Functionality - Maintains display compatibility and prevents resolution mismatches during setup. Metal Housing with Mounting Brackets - Ideal for secure installation in industrial and professional settings. APPLICATIONS: Projectors & Interactive Displays - Extend AV content from classroom control points to displays and touchscreens in educational environments. Dual-Screen Conferencing Setups - Power presentation and collaboration workflows in boardrooms and meeting spaces using remote display sources. Digital Signage Screens - Distribute promotional or informational content across large retail areas from a centralised media player. Information Displays in Healthcare - Deliver real-time content to waiting rooms and hallways from secure, remotely located source devices. Set-Top Boxes & Media Servers - Mirror and distribute home entertainment content to TVs in other rooms without relocating hardware. Control Room Displays & Workstations - Extend AV and USB signals from secure back-end systems to operator consoles in monitoring, security, or industrial environments.
The Lindy 70m Cat.6 HDMI 4K30 and IR Extender is designed for AV professionals and system integrators needing to extend HDMI and IR signals up to 70 meters over a single Cat.6 cable. Its key benefit is simplifying installations with Power over Cable (PoC) and offering versatile display options via HDMI loop-out. A potential caveat is the 4K@30Hz resolution limit, which may not suit applications requiring higher frame rates.

Extended Product Information
FAQs
What is the maximum resolution and distance supported?
The extender supports resolutions up to 3840 x 2160 @ 30Hz (4K) with 4:4:4 8-bit color. The maximum transmission distance is 70 meters for 1080p resolution, and up to 40 meters for 4K resolution, when using a high-quality Cat.6 cable.
Does this extender support Power over Cable (PoC)?
Yes, the extender features PoC. This means only one AC power adapter is needed, connected to the transmitter unit. The receiver unit is powered through the Cat.6 cable.
Can I control my source device from the display location?
Yes, the extender includes IR pass-through functionality. You can connect the provided IR receiver and emitter cables to control your source device remotely from the display end.
What type of cable is required?
A Cat.6 Unshielded Twisted Pair (UTP) cable is required for optimal performance. For distances approaching the maximum, solid core Cat.6 cable is recommended.
What is the purpose of the HDMI Loop-Out port on the transmitter?
The HDMI Loop-Out port on the transmitter allows you to connect a local display simultaneously. This is useful for monitoring the AV signal at the source location or for creating a dual-zone display setup.
Does it support HDCP?
Yes, the extender supports HDCP version 1.4.
How do I reset the EDID information?
The EDID data can be copied from the connected display. To reset or re-copy, you can power cycle the extender units (turn off the transmitter's power, disconnect and reconnect the Cat.6 cable, then power the transmitter back on).
Troubleshooting
No video or audio signal is transmitted.
Verify that all HDMI and Cat.6 cables are securely connected at both the transmitter and receiver ends. Ensure the AC adapter is connected to the transmitter and receiving power. Check that the source and display devices are powered on and set to the correct inputs. Confirm the Cat.6 cable is not damaged and is of good quality. Try cycling power on all connected devices.
Poor video quality or flickering image.
This may be due to the Cat.6 cable quality or length. Try using a higher quality, solid core Cat.6 cable. If the distance is close to the maximum 70m, consider reducing the cable length if possible. Ensure the resolution and refresh rate are supported by both the source and display devices (maximum 4K@30Hz).
IR control is not working.
Ensure the IR emitter is pointed towards the source device's IR receiver and the IR receiver is pointed towards the display device's IR receiver (or control system). Check that the IR cables are connected to the correct ports (IR OUT on transmitter, IR IN on receiver) and are not damaged. Verify the IR frequency range compatibility (20-60 kHz).
Resolution mismatch or incorrect display output.
The EDID Copy function should maintain compatibility. Try resetting the EDID by power cycling the extender units. If issues persist, manually set the resolution on the source device to a common supported resolution (e.g., 1080p@60Hz) to test.
Pros and Cons

Simplifies installation with PoC, requiring only one power supply.
Extends signals up to 70m over a single, inexpensive Cat.6 cable.
Offers flexibility with HDMI loop-out for local monitoring or dual-zone setups.
Supports remote control of source devices via IR pass-through.
Robust metal housing suitable for professional installations.
Cons
Maximum resolution is limited to 4K@30Hz, not suitable for 4K@60Hz or higher.
Performance is dependent on the quality of the Cat.6 cable used.

Setup, Compatibility & Care
Setup:
Connect your HDMI source device to the HDMI IN port on the transmitter unit.
Connect your display device(s) to the HDMI OUT (LOOP OUT) port on the transmitter and/or the HDMI OUT port on the receiver unit.
Connect the IR emitter cable to the transmitter's IR OUT port and the IR receiver cable to the receiver's IR IN port.
Connect the transmitter and receiver units using a single Cat.6 U/UTP cable (solid core recommended for best performance).
Connect the included AC power adapter to the transmitter unit and plug it into a power outlet. The receiver unit will be powered via PoC.
Ensure all devices are powered on. The extender supports HDCP 1.4.
Compatibility:
Cable: Requires a Cat.6 U/UTP cable. For maximum distance and performance, use solid core Cat.6 cable. Lower quality or different cable types (e.g., Cat.5e, stranded core) may reduce the maximum transmission distance or quality.
Resolution: Supports up to 3840 x 2160 @ 30Hz (4:4:4 8-bit). Ensure your source and display devices support these resolutions.
