Enclosure unit design

Partition design guide

When making a case for the enclosure, make sure to separate the inlet and outlet with a partition.

Place sponge pads, etc., between the partition and the enclosure to completely block air flow.

Partitions when installing with an optional media player

• When installing a media player as an external component, make sure it is separated from the enclosure.

21

NOTE

There should be no gap between the media player and outdoor unit; only allow cables through the partition.

The optional media player is an additional source of heat and the increased temperature inside the enclosure unit may cause the outdoor unit to malfunction.

- This malfunction occurring in this manner will not be covered by the warranty.

If the partition is not applied, air from the outlet may enter the unit again through the inlet.

- This may reduce the heat dissipation performance of the product and is not warranted in this case.

• If a separate case is installed on the vessel, design it with the recommended opening area and aperture. Failure to meet the recommended aperture plane and aperture ratio may cause the product to malfunction. In such cases, the warranty does not apply.

NOTE

The partition should be in close contact with the case as well as with the enclosure when installed.

It is recommended that the inlet and outlet be located at the same position as the enclosure.

If possible, install ventilation openings around the inlet and outlet of the enclosure.

If you install both sides or multiple units together, you must increase the opening area by the number of installed units.

When Installing the HDBaseT Cable

The HDBaseT CABLE Install

LAN cables are fairly resilient. Yet, any rough handling, such as tight tie wraps, clamping or stapling can damage the cable, compromising performance or even preventing signal transmission. Tie cables loosely with appropriate cable wraps.

Another important issue for cable integrity is the bend radius. Bend radius is the inside curve of the cable during and after installation. It is best to keep the minimum bend radius at least at four times the diameter of the cable.

Cables should be kept at a distance of at least 30 cm from power cables. In an environment prone to high EMI, it is best to use shielded cables. Most Cat5e cables are unshielded, which makes them more flexible, durable and inexpensive. Thou shalt keep your cables away from power sources If using unshielded cables, keep them away from any source of EMI such as other cables, transformers and light fixtures. In high RF environments, it is best to use shielded cables.

If possible, avoid patch cords or cables altogether, as every connection introduces losses in the transmission. If absolutely necessary, make sure to use less than two per cable run and keep each less than five meters from the end.

HDBaseT Recommended cable

• Visit the website ( https://hdbaset.org/hdbaset-recommended-cables ) and refer to information in details.

Using Patch Cables (Ex: CAT6 FTP)

The total run of an HDBaseT cable installation may include up to two patch cables. This is referred to as a threesegment installation.

There is no sound output.

- See if the audio cable is connected properly.

- Adjust the volume of the product or external device.

- See if the sound is set properly.

Sound is too dull.

- Select the appropriate equalizer sound.

Sound is too low.

- Adjust the volume of the product or external device.

For some models, you will need to purchase external speakers separately since they do not have speakers built-in.

Other Issues

• The power suddenly turned off.

- Check if the auto-off function is activated on the settings related time.

- Power source has not being supplied properly. See if the product power cord is connected properly.

- Check the power control settings.

If the internal temperature of the enclosure rises, the power may shut down. Make sure to regularly clean the heat exchanger within the enclosure.

Image sticking

After-image appears when the product is turned off.

- If you use a fixed image for a long time, the pixels may be damaged. Use the screen-saver function.

- When a dark image is displayed on the screen after an image with high contrast (black and white or gray), this may cause image sticking. This is normal for display products.

When the LCD panel displays a static image for an extended period of time, it can cause a voltage difference between the electrodes that operate the liquid crystals. When the voltage difference between the electrodes builds up over time, liquid crystals have a tendency to remain aligned in one direction. During this process, a previously displayed image remains visible. This phenomenon is referred to as image sticking.

Image sticking does not occur when using constantly changing images but may occur when using a fixed image for an extended period of time. Therefore, it is recommended that you use the instructions below to decrease the likelihood of image sticking occurring when using a fixed image. It is recommended that you change the screen at least once every 12 hours at the very minimum; if done more frequently, the prevention of image sticking is more effective.

• Recommended operating conditions

1

Change the background and the character colors using the same time interval.

- When changing colors, using complementary colors helps to prevent image sticking.

A A

ITO or MoTi Pixel Layer

2

Change the image using the same time interval.

- Make sure that the characters or images before changing the image remain in the same location after changing the image.

NOTE

When using HDMI / HDBaseT / DisplayPort inputs, PC and DTV resolutions can be adjusted in the Input Label.

Vertical frequency: The product display functions by the screen image changing dozens of times every second like a fluorescent lamp. The vertical frequency or refresh rate is the number of times the image display is repeated per second. The unit is Hz.

Horizontal frequency: The horizontal interval is the time taken to display one horizontal line. When 1 is divided by the horizontal interval, the number of horizontal lines displayed every second can be tabulated as the horizontal frequency. The unit is kHz.
