4K HDMI cable
[Fig. 5.1] Cascade connection
At IDK, various cables, such as flexible HDMI cable, DVI cable, high-quality long cables and conversion
cables, are available. Please contact us for details as needed.
Use correct HDMI cable /HDMI-DVI conversion cable according to the system configuration. For analog audio,
use a commercial audio cable.
For 4K format video, the maximum TMDS data rate (transmission rate) is 18 Gbps. If you use a high-speed HDMI
cable, the rate becomes 10.2 Gbps and video cannot be displayed stably.
Use a cable supporting 18 Gbps high-speed transmission according to the 4K format. Since extension
distance depends on the cable type and characteristics of source and sink devices, we recommend that you
use a high-quality cable.

6 Precautions before connection
Follow the precautions below before connecting to external devices.
■Attaching rubber feet
1. Turn the VAC upside down and place it on a flat place.
2. Wipe the dirt off joint area.
3. Peal the release papers from rubber feet and place them on each corner of the VAC.
■
Installation
・Eliminate static electricity from your body before connecting cables.
・Do not place another VAC on the VAC.
・Do not block vent holes. Keep enough space (1.2 in. (30 mm) or more) around the product.
・Do not install the VAC in a closed space.
If you have to install the product to an EIA rack mount in closed space, add a ventilation to keep the
ambient temperature of 40 degrees C/104 degrees F or less. If inadequately vented, the life of parts
may be shortened and operations may be affected.
■
Cabling
・Read the manuals of external devices carefully
・Turn off the transmitter/receiver before connection.
・Insert the cable into the connector firmly and do not give the connector stress.
・Secure the HDMI cable using a cable clamp to prevent it from falling out of the device.

Note:
If cascade connection is employed, the source device will read the EDID of the source-device-side VAC. If
two or more distributors are connected between a sink device and source device, follow the procedure below
to read EDID data.
1. Copy the EDID of the sink device into the sink-device-side VAC and set it as “Copied EDID” or
“EXTERNAL (External EDID)”.
2. Copy the EDID of the sink-device-side VAC into the source-device-side VAC and set it as
“Copied EDID” or “EXTERNAL (External EDID)”.
