AVICO HKU-A1B-0202 2×2 HDMI 2.0 KVM Switch

INTRODUCTION

The HKU-A1B-0202 is a 2-port Dual-monitor HDMI 2.0 KVM Switch, offering USB 3.0/Dual-HDMI video/Audio & Mic console connectors. Users can effortlessly access two HDMI-enabled computers using either of the PC1/PC2 pushbuttons on its front panel or an optional wired QuickSwitchTM button connected to its REMOTE connector. This allows you to use a USB keyboard, a USB mouse, two 4K UHD monitors, a speaker set, and a microphone on a console for accessing two HDMI-enabled computers.

For intuitive and fast switching between two computers, you can not only press the PC1/PC2 pushbuttons or the optional wired QuickSwitchTM button but also input their corresponding keyboard hotkeys. This dual-monitor HDMI 2.0 KVM switch supports a maximum video resolution of 3840 x 2160@60Hz, ensuring optimal display quality to meet your specific requirements.

This 2×2 HDMI 2.0 KVM switch functions in two modes: Single-port Switching Mode, consisting of two states, and Hybrid Switching Mode, consisting of four states. The Hybrid Switching Mode enables the simultaneous display of these sources on the two console monitors, providing greater flexibility and customization in managing your display configurations.

Front & Rear Panels

OPERATION

HKU-A1B-0202 is operated through two operation modes: Singleport Switching Mode consisting of states 1 and 2 and HybridSwitching Mode consisting of states 3, 4, 5, and 6. The state 1 of Single-port Switching Mode is the factory default state.

1. Front-panel PC1/PC2 Push button Operation Refer to the following diagram, where the utilization of the front panel PC1/PC2 buttons enables a direct switching between states 1 and 2. For details regarding the operation of the PC1/PC2 buttons, please consult the [7. Hotkey Reference List] section on the next page.
2. Keyboard Hotkey Operation You may use various keyboard hotkeys to operate the KVM. Each keyboard hotkey includes at least three (some include four) consecutive keystrokes. The leading two keystrokes define the hotkey preceding sequence. Note that a hotkey preceding sequence should be pressed within 2 seconds. Otherwise, the input hotkey preceding the sequence will be considered invalid. See more details in [7. Hotkey Reference List] section on the next page for available keyboard hotkeys.

Essential Notes for the Unit Operation

• The PC1/PC2 button only applies between states 1 and 2 of the Single-port Switching Mode.
• As only states 1, 2, 5, and 6 are equipped with EDID Emulation function, the monitors will not undergo the hot-plug detection

procedure during transitions between these states. Therefore, the application window(s) will stay at (their) original position on the extended desktop of the two monitors. However, once the user operates switching to state 3 or 4, the monitors will undergo the hot-plug procedure, which might result in the re-arrangement of the application window(s). The Below diagram illustrates the issue of rearrangement of the App. windows between the two scenarios described above.

CONNECTION DIAGRAM
The diagram illustrated below is an example, the actual application may vary. All illustrated computers, accessories, and monitors are not included in the package, it is for reference only.

INSTALLATION

1. Utilize two HDMI cables and one USB cable to establish connections between HDMI Input A (p), HDMI Input B (q), and USB 3.0 Port (r) with the primary video output (p), secondary video output (q), and USB port of PC1 (r).
2. Replicate the step 1 procedure with PC2. Connect HDMI Input A (m), HDMI Input B (n), and USB port (o).
3. Connect the primary monitor input to the HDMI A output (k). The secondary monitor connects to HDMI B output (l).
4. Connect a keyboard and mouse to the dedicated USB ports (j).
5. Connect a microphone to the designated (d) microphone jack and a speaker to the designated (e) speaker jack.

In addition to the unit panel control, the KVM also offers external control options, including an IR Remote Control and a wired QuickSwitchTM button. To switch the unit to a preferred operation state with the IR Remote Control, directly press a corresponding state selection button on the IR Remote Control.

Please be aware that the completion of the state-switching process may take one to a few seconds. If you Press these buttons too rapidly, the unit will always consider the last button press as effective, and any previous button presses will be immediately ignored. The below diagram shows two methods of the unit’s external control, including the wiredQuickSwitchTM button and the IR Remote Control.

FAQS

Q1: What specifically is the Secondary-video Focus Operation referred to in the HKU-A1B-0202 datasheet?
Ans: Both of these operations are contrasted with the conventional States 1 and 2. The following illustration specifically depicts the Secondary-video Focus Operations, wherein the Primary Videos remain constant while the Secondary Videos vary.

Q2. Whenever my operation transitions to States 3 or 4, the previous position of the application window in the secondary monitor area appears to be rearranged to the primary monitor area.
Is it possible to resolve this issue?
Ans: Only the switching operations among States 1, 2, 5, and 6 support EDID emulation, where no hotplug procedure will be executed. When the switching operation transitions to States 3 or 4, involving the simultaneous display of dual primary video sources, EDID emulation will be revoked through the Hotplug Detection procedure. The hot plug detection (HPD) procedure necessitates the removal of the two previous secondary video sources, causing all previous application window(s) associated with the secondary video sources to be rearranged and displayed on the primary video sources. Refer to the illustration in the [6. Operation] section for clarification.
