5. Opstelling en installering

Follow these steps to connect your computers and monitors to the KVM switch.

5.1. Connection Diagram (KVM Mode)

Image: A detailed diagram showing how to connect two PCs to the KVM switch for KVM mode. Each PC connects via two HDMI cables and one USB-B cable to the KVM. Monitors connect to the KVM's HDMI outputs. Keyboard, mouse, and other USB peripherals connect to the KVM's front USB ports. Audio devices connect to the 3.5mm audio ports.

In KVM Mode, both monitors display the selected PC (PC 1 or PC 2). Press the switch button to toggle between PC 1 and PC 2 on both monitors.

5.2. Connection Diagram (USB Mode)

Image: A detailed diagram showing how to connect two PCs to the KVM switch for USB mode. Similar to KVM mode, but Monitor A can display PC 1 and Monitor B can display PC 2 simultaneously. The KVM switch then only switches the USB devices between the two PCs.

In USB Mode, Monitor A can display PC 1 and Monitor B can display PC 2 simultaneously. The KVM switch will only switch the connected USB devices (keyboard, mouse, etc.) between the two PCs.

5.3. Common PC Source Connection Methods

Image: This diagram illustrates four different connection scenarios for desktops and laptops, including using DisplayPort to HDMI cables, USB-C to HDMI adapters, and docking stations. It emphasizes that each PC must connect both HDMI input ports (e.g., 1A & 1B) and the USB host port of the KVM switch for dual monitor setup.

Belangrike notas:

• Ensure each PC connects both HDMI input ports (e.g., 1A & 1B) and the USB host port of the KVM switch for dual monitor setup. Otherwise, one of the monitors may not display any image.
• It is recommended to use high-quality converter cables/docking stations produced by a professional manufacturer. Otherwise, the monitors may not display any image.

6. Operasie

6.1. Omskakeling tussen rekenaars

You can switch between connected computers using two methods:

• Voorpaneel-knoppie: Press the "Switch" button on the front panel of the KVM switch to cycle between PC 1 and PC 2.
• Keyboard Hotkey: Press "Tab" + "1" (for PC 1) or "Tab" + "2" (for PC 2) simultaneously on your connected keyboard.

Hotkey Notes:

• The hotkey function is enabled by default. It can be disabled by pressing the combined keys (Left Ctrl + Alt + Shift + ]) if you don't need the function.
• You can also change the hotkey from "Tab" to "Caps Lock" if needed. Refer to the "Hotkey Function" part in the user manual for more details.

6.2. Vertoonmodusse

The KVM switch supports two primary display modes:

Image: A diagram showing two display modes. Display Mode 1 illustrates mirrored or extended display from a single PC across two monitors. Display Mode 2 shows two different PCs displayed simultaneously on two separate monitors, with USB devices switchable between them.

• Display Mode 1 (KVM Mode): Both monitors display the same PC (mirrored) or an extended desktop from a single PC.
• Display Mode 2 (USB Mode): Monitor A displays PC 1, and Monitor B displays PC 2 simultaneously. The keyboard, mouse, and USB devices can be switched between the two PCs.

6.3. Advanced EDID Emulation Function

The KVM switch incorporates EDID emulation to prevent common display issues when switching between computers.

With EDID emulation, your desktop icons and window arrangements remain consistent after switching, eliminating issues like icon rearrangement, screen flickering, or windows being compressed onto a single monitor.

6.4. Automatic PC Wake-up

The KVM switch is designed to automatically wake up a sleeping PC when you switch to it, eliminating the need to manually move the mouse or type on the keyboard.

6.5. Keyboard and Mouse Compatibility

The KVM switch supports a wide range of keyboards and mice, including those with dedicated software, thanks to its pass-through mode and upgraded hotkey algorithm.
