The Comprehensive CHE-1 is a 4K HDMI extender with IR control, designed to extend high-definition video/audio and IR control signals over long distances using a single CAT6 or CAT5E cable. This device facilitates the transmission of signals up to 230 feet (70 meters) for 1080p resolution and 131 feet (40 meters) for 4K@30Hz resolution, offering a zero-delay, uncompressed transmission experience between the transmitter and receiver units.

Function Description:

The CHE-1 system consists of two main components: a transmitter and a receiver. The transmitter unit is responsible for receiving the HDMI signal from a source device, such as a DVD player or set-top box, and converting it for transmission over a CAT5E/6 cable. It also features an HDMI loop out port, allowing for local monitoring or cascading to another extender, supporting resolutions up to 4K@30Hz. An IR OUT port on the transmitter enables the transmission of IR control signals, which are received from the IR IN port on the receiver, back to the source device. The EDID DIP switch on the transmitter provides flexibility in EDID management, allowing users to copy EDID information from either the HDMI loop out display or the receiver's display to the signal source. This ensures optimal compatibility and display settings. The CAT output port on the transmitter connects to the CAT input port of the receiver via a CAT5E/6 cable, forming the long-distance transmission link.

The receiver unit, on the other hand, takes the signal from the CAT5E/6 cable via its CAT IN port and converts it back into an HDMI signal for output to a display device like an HDTV. It also includes an IR IN port to receive IR control signals from the display area, which are then transmitted back to the source device through the transmitter's IR OUT port. This bidirectional IR control allows users to control the source device from the remote display location. Both the transmitter and receiver units are powered by 5V/1A DC power adapters, and each unit features a Power LED to indicate when it is powered on, as well as a Link LED to show when it is successfully connected to an HDMI source.

The CHE-1 supports various audio formats, including PCM7.1, Dolby True HD, and DTS HD, ensuring high-quality audio transmission alongside video. Its ability to cascade via an additional HDMI loop out port makes it suitable for more complex setups requiring multiple displays or extended reach.

Usage Features:

The CHE-1 is designed for ease of use and flexible installation, making it suitable for a wide range of applications, including multimedia conference halls, TV teaching environments, and large-screen displays. Its compact design allows for discreet placement.

• Extended Reach: The primary feature is its ability to extend HDMI and IR signals over significant distances. For 1080p resolution, it can reach up to 230 feet (70m) with CAT6 cable and 197 feet (60m) with CAT5E. For 4K@30Hz resolution, the distances are 131 feet (40m) with CAT6 and 115 feet (35m) with CAT5E. This provides considerable flexibility in system design, especially when the source and display are far apart.
• IR Control: The integrated IR control functionality allows for seamless control of the source device from the remote display location. This means users don't need to be near the source device to operate it, enhancing convenience in home theater or commercial settings. The IR blaster and receiver cables are included, with clear pin definitions provided for proper connection.
• EDID Management: The EDID DIP switch on the transmitter offers a crucial feature for ensuring compatibility between the source and display. By allowing users to copy EDID information from either the local loop out display or the remote receiver display, it helps to resolve potential display issues and ensures the optimal video and audio settings are used.
• HDMI Loop Out: The HDMI loop out port on the transmitter is a versatile feature. It can be used for local monitoring, allowing a display to be connected near the source device. More importantly, it enables cascading, meaning multiple CHE-1 units can be linked together to extend the signal even further or to distribute it to multiple displays. This supports resolutions up to 4K@30Hz even when cascaded.
• High-Quality Transmission: The extender supports HDMI 1.4 and HDCP 1.4, ensuring compatibility with a wide range of modern HDMI devices. It also supports video resolutions up to 4K@30Hz and audio formats up to 7.1CH HD audio, guaranteeing a high-quality multimedia experience.
• Plug-and-Play Operation: The device is designed for straightforward connection. Users simply connect the HDMI source to the transmitter's HDMI IN, the local display to the HDMI OUT (if desired), and the CAT5E/6 cable between the transmitter and receiver. The remote display connects to the receiver's HDMI OUT. Powering on both units completes the setup.
• Robust Design: The units feature a metal enclosure, providing durability and protection for the internal components. The black color and compact dimensions allow for discreet integration into various environments.

Maintenance Features:

While the manual does not explicitly detail maintenance procedures, the design and components suggest a low-maintenance device.

• Surge Protection Recommendation: The manual strongly recommends the use of surge protection systems. This is a critical maintenance feature, as it protects the sensitive electrical components of the CHE-1 from damage caused by electrical spikes, surges, electric shock, and lightning strikes. Implementing surge protection will significantly extend the lifespan of the equipment and prevent costly repairs or replacements.
• Durable Construction: The metal enclosure of both the transmitter and receiver units contributes to their longevity. Metal provides better heat dissipation and protection against physical damage compared to plastic housings, reducing the likelihood of internal component failure due to environmental factors or accidental impacts.
• Simple Power Supply: The use of standard 5V/1A DC power adapters means that replacement power supplies are readily available if needed, simplifying troubleshooting and maintenance in case of power-related issues.
• Environmental Considerations: The specified operating temperature range of 32 - 104°F (0 - 40°C) and storage temperature range of -4 - 140°F (-20 - 60°C), along with a relative humidity range of 20-90% RH (non-condensation), indicate that the device is designed to operate reliably in typical indoor environments. Maintaining these conditions will help ensure the device's long-term performance.
• User Manual for Reference: The provision of a user manual is a key maintenance feature. It serves as a comprehensive guide for installation, operation, and troubleshooting. Users are advised to keep the manual for future reference, which is essential for addressing any operational questions or issues that may arise over time.

In summary, the Comprehensive CHE-1 is a versatile and robust HDMI extender that offers extended reach, bidirectional IR control, and flexible EDID management, all within a compact and durable design. Its features are geared towards providing a reliable and high-quality solution for long-distance HDMI signal transmission in various professional and home entertainment settings.
