Troubleshooting

HDMI signals run at a very high frequency and are especially susceptible to bad video connections, too many adapters,

or cables that are too long. To avoid the loss of an image or introduction of image jitter, follow these guidelines:

The HDMI cable on the input to the transmitter or the output of the receiver should not exceed 10' (3 m).

Use only cable designed for HDMI signals.

Limit or avoid the use of adapters.

If the display exhibits a flashing black or blue screen, snow, or other distortion, a non-HDCP compliant display may be receiving an HDCP-encrypted signal.

Check for an HDCP problem by ejecting the DVD from the player. If the display distortion stops and the DVD menu or screen saver image is clear, the problem is HDCP-related.

The HDMI 201 works as described in point-to-point applications. Do not use any additional adapters, patch panels, or couplers with the input HDMI cables, output HDMI cables, and/or twisted pair cables. Additional links in the signal chain can result in the reduction of signal integrity and overall cable length performance.

Application Examples

Audio conversion

Figure 2-27 shows a standard installation with HDMI video and an audio input. The HDMI 201 A D Tx converts the video input into two proprietary TP outputs. The Tx outputs the audio directly on a captive screw connector.

HDMI 201 Rx specifications

The Extron Electronics HDMI 201 Rx is a versatile and high-performing HDMI receiver designed for professional AV installations. This device is engineered to extend HDMI signals up to 230 feet (70 meters) using a single Cat 6a or better cable, ensuring that high-definition video and audio can be transmitted over long distances without compromising quality.

One of the standout features of the HDMI 201 Rx is its ability to support resolutions up to 4K at 30Hz, along with 1080p video at 60Hz. This makes it an excellent choice for environments where crisp, high-resolution visuals are critical, such as classrooms, conference rooms, and auditoriums. The receiver also supports various audio formats, including LPCM, Dolby Digital, and DTS, ensuring that users receive a comprehensive audio experience.

Another key technology employed in the HDMI 201 Rx is EDID (Extended Display Identification Data) management, which allows the receiver to communicate with connected displays to ensure optimal performance. This feature helps prevent compatibility issues and guarantees that the video output is tailored to the capabilities of the display device.

The HDMI 201 Rx also incorporates a unique feature known as HDBaseT technology, which enables the transfer of HDMI signals, Ethernet, and power over the same cable. This simplifies overall installation, reducing cable clutter and minimizing the number of required components. Additionally, the receiver includes built-in support for Power over Ethernet (PoE), allowing it to be powered through the same cable that carries the data signal, which can be a game-changer for ease of installation.

Integrators will appreciate the compact design and low-profile form factor of the HDMI 201 Rx, which allows for discreet integration into various environments.
