Product Introduction

The DV-HSW4K-41AUD is an ultrathin auto switcher with four HDMI video inputs and one HDMI output. This switcher supports HDMI video resolution up to 4K@60Hz 4:4:4 HDR and multichannel audio. Besides passing EDID information from the display, there are multiple built-in EDID settings to simplify an installation. The switcher will de-embed digital stereo audio to provide an analog audio source for an audio system. The switcher also supports an audio return channel (ARC) for transmitting audio back to the HDMI input port from the connected display.
In auto-switch mode, it switches to an HDMI input as soon as a new source is connected. When the active input is removed, the switcher will select the first source on the lowest numbered input. The switcher may also be controlled via RS232, IR with the included remote, or from the source button on the front of the switcher.

System Diagram

The following diagram illustrates typical input and output connections that can be utilized with this switcher:

Source Button Control

Manual Switching

When the switcher is in manual switching mode, the Switching Mode LED will be green, and pressing the Auto/Source button will switch to the next input.

Automatic Switching

To enable automatic switching, press and hold the Auto/Source button for three seconds. The Switching Mode LED will turn yellow.
When in auto-switch mode, the switcher follows the below rules:

New Input: Upon detecting a new input, the switcher will automatically select the new source.
Reboot: Once power is restored to the switcher if the last selected source is still available, the switcher will still output this signal, otherwise, the switcher will switch to the first available active input starting at HDMI Input 1.
Source Removed: When an active source is removed, the switcher will switch to the first available active input starting at HDMI Input 1.

IR Remote Control

Connect the IR receiver to the IR input port; the IR remote is used for input switching and it can also be used to control source and display devices based on CEC functionality.

Note

HDMI input 4 port does not support CEC, the source device connected to this port cannot be controlled via the IR remote.
The source and display devices are required to support CEC when the IR remote is used to control them.

RS232 Control

Connect the switcher to the control device (e.g., PC, Control System) with an RS232 cable and set the parameters correctly.

EDID Management

Predefined EDID Setting

The rear panel provides a 4-pin DIP switch to set a predefined EDID. The unit has ten types of embedded EDID and their corresponding switch status are shown in the list below.

When in the lower position, the switch represents “ON”, while putting the switch in the up position, it represents “OFF”.

User-Defined EDID Setting

There are five EDID settings that can be customized following the below operations.

Rename the user-defined EDID according to the following format.

EC_xx_xxxx_xxx.bin

EC: Represents EDID.
xx: Represents EDID ID. It is 11~15.
xxxx: Represents the video parameter.
xxx: Represents the audio format.

Example: EC_11_720P_LPCM.bin

Power on the switcher, and then connect the switcher to the PC with a USB cable. The PC will automatically detect a U-disk named “BOOTDISK”.
Double-click the U-disk, a file name of “READY.TXT” to view.
Copy the user-defined EDID (such as EC_11_720P_LPCM.bin) to the “BOOTDISK” U-disk.
Reopen the U-disk to check the filename “READY.TXT” this should automatically become “SUCCESS.TXT”, if yes, the user-defined EDID was imported into the switcher and saved as its corresponding EDID ID successfully.
Repeat the above third to the fifth step to copy another user-defined EDID to the “BOOTDISK” U-disk.
Remove the USB cable, and connect the adaptor to power on the switcher.
The new EDID also can be invoked via the 4-pin DIP switch directly. The EDID ID and its corresponding switch status are shown in the below list.

ID	Switch Status
11	1011
12	1100
13	1101
14	1110
15	1111

ARC Mode

Audio Return Channel (ARC) allows audio from a display to pass “upstream” through an HDMI cable to an audio processing device, such as an AV amplifier. When ARC mode is active on the switcher, the ARC stream will pass to the active HDMI source device if it can process the signal. Only the fourth HDMI input port features ARC, when the display and AV amplifier support ARC, the audio connection diagram is shown below:
