This document describes the HDMI over CAT5e Transmitter with HDMI Loop-Out, an installation guide for a device designed to extend high-definition video and audio signals over long distances using CAT5e/6 cables. The primary function of this transmitter is to provide a cost-effective solution for distributing HDMI signals to multiple locations, making it suitable for various setups where displays are spread out or require extended cable runs.

Function Description

The HDMI over CAT5e Transmitter with HDMI Loop-Out serves as a central hub for your HDMI source, taking an input HDMI signal and converting it for transmission over standard CAT5e/6 Ethernet cables. This allows for significantly longer cable runs than traditional HDMI cables, which are typically limited in length. The device also includes a local HDMI output, referred to as a "loop-out," which enables you to connect a local display directly to the transmitter, mirroring the signal being sent over the CATx cable. This is particularly useful for monitoring the source content or for setups where a local display is required near the source.

The core technology behind this device involves extending HDMI video and audio transmission to displays over CAT5e/6 cable cabling. It is compliant with HDMI Deep Color and 3DTV standards, ensuring that it can handle modern high-quality video formats. Furthermore, it is HDCP and DVI compliant, which means it can work with protected content and integrate with DVI-based systems using appropriate adapters. The device supports pure, unaltered, uncompressed 7.1 channel digital HDMI transmission over the CATx cable, preserving the integrity of both video and audio signals. It also supports embedded EDID (Extended Display Identification Data) and EDID learning from the connected HDMI display, which helps ensure optimal compatibility and resolution settings between the source and the display. The EDID learning feature is crucial for resolving potential compatibility issues by allowing the transmitter to communicate the display's capabilities back to the source.

Usage Features

The transmitter offers several features that enhance its usability and flexibility in various installation scenarios. One key feature is its ability to extend HDMI signals over CAT5e/6 cables, with specified transmission distances depending on the resolution. This allows for greater flexibility in placing displays far from the HDMI source. The local HDMI output is a significant convenience, providing a direct connection for a display near the transmitter, which can be used for monitoring or as part of a multi-display setup.

The device includes a DIP switch for configuring different operational modes, which is essential for optimizing performance based on the specific setup. These modes include:

Default Mode: This mode is designed for 1080p video and 7.1 channel surround sound audio. It's the standard setting for most high-definition setups.
Safe Mode: If you encounter issues with video but no audio, or if your HDMI source is set to output 1080p resolution and the display doesn't support it, Safe Mode can be used. This mode provides 1080p video with stereo output and is recommended when the HDMI source's output is set to a resolution less than 1080p or "Auto."
EDID Learning / EDID Learning & Stereo Mode: These modes are critical for ensuring compatibility between the HDMI source and the connected display. By powering off the transmitter, connecting an HDTV to the HDMI Output, setting pin-1 of the DIP switch to "On," and then powering on the devices, the transmitter can learn the EDID from the HDTV. This process takes a few seconds and helps the source send an optimal signal to the display. The EDID Learning & Stereo Mode combines EDID learning with stereo audio output.

The device also features an audio output, a 3.5mm audio jack, allowing you to plug in local stereo speakers. This is useful for setups where audio needs to be played back locally at the transmitter's location. The RJ-45 Out port is designed for linking to the next transceiver or receiver in a cascading setup, providing scalability for larger installations. The presence of an HDMI In LED indicates when the HDMI source is powered on and working properly, offering a quick visual status check.

For installation, the process involves connecting all devices, including displays and speakers, to the transmitter. The HDMI source connects to the HDMI In port, a local HDMI display connects to the HDMI Out, and local stereo speakers can be connected to the Audio Out. The CAT5e cable connects the RJ-45 Out to the next transceiver or receiver. Finally, the included power adapter is plugged into the Power Jack, and all devices are powered on.

Maintenance Features

The installation guide provides important safety guidelines and recommendations for maintaining the device and ensuring its longevity. It advises against attempting to service the unit yourself, emphasizing the importance of professional handling for repairs. Proper ventilation and air circulation are crucial for the device's operation, and it should not be used near water to prevent damage. Keeping objects that might damage the device at a safe distance and placing the unit on a stable surface are also recommended.

For cleaning, the guide specifies not to use liquid or aerosol cleaners. Instead, it advises unplugging the power to the unit before cleaning, suggesting a dry cloth or similar method to prevent electrical hazards and damage to the components. The manual also stresses the importance of using only the power adapter and accessories that came with the unit, as using incompatible accessories could lead to malfunction or damage.

Regarding cable recommendations, the guide suggests using T568B CAT cable for the best performance and shielded STP (Shielded Twisted Pair) cables to avoid EMI (Electromagnetic Interference) problems. For resolutions greater than 1080i or 1280x1024, a CAT6 cable is recommended, highlighting the importance of cable quality for optimal signal transmission at higher resolutions. These recommendations are key to ensuring stable and high-quality video and audio transmission over long distances, minimizing potential issues related to signal degradation or interference.
