The seamless KVM Switch KSW-4K4H-U30 allows users to monitor and manage four computers, with support for asynchronous audio switching and USB 3.2 peripheral sharing. Users can easily switch between computers via front panel push buttons, hotkeys, keypad control, or serial commands. This zero-latency KVM switch combines HDMI video, 3.5mm audio, and a USB 3.0 hub in a compact design to reduce desk clutter and enhance productivity.

USB HID and USB 3.0 Hub Support

The KSW-4K4H-U30 features built-in USB HID ports and a USB 3.0 hub. The KVM USB hub allows seamless sharing of USB peripherals without requiring any software or driver installation. The real-time USB HID switching provides a smooth user experience, while the USB 3.2 Gen 1 port delivers high-speed data transfer at up to 5 Gbps. The USB 3.0 hub is compatible with macOS, Linux, Chrome OS, and Windows 8 or later.

Independent Audio Switching

A unique tracking system enables the Audio devices to be operated independently or concurrently. Users can choose whether audio switching follows the active PC or does not follow the computer switching. This is useful, for example, when listening to music from one PC while working on another.

Auto Scan and Manual Scan

To monitor real-time PC status, the KVM switch supports an Auto Scan function with adjustable scan intervals to automatically cycle through active PCs. Manual Scan is also available, allowing users to switch between PCs one-by-one using the keyboard. 

EDID Management

The seamless KVM switch provides 1 Auto and 63 EDID preset settings and supports monitors with 16:9 / 21:9 / 32:9 aspect ratios. The unique EDID configuration technology supports unified and continuous video streaming, which ensures optimized video output and prevents video flickering or black-screening issues when switching KVM Host Ports.

Video Scaling Function

The KVM switch provides 4-stage image scaler settings to select and ensure the image is output in native resolution, customized resolution, or a resolution limited to 4K/1080p. With the aid of Hotkey, it also provides support and compatibility for 16:9, 21:9, and 32:9 screen resolutions.

Serial Control (RS-232 & Virtual COM)

Equipped with an RJ-11 serial interface (for DB9 to RJ11 cable) and a USB-C virtual COM port, the KVM switch supports control via PC, serial controller devices, or home automation systems. Serial command switching is designed for industrial and automation applications, enhancing KVM and serial device integration.

Keypad-IN Control Function

The Keypad-IN feature allows KVM switching via a wired or wireless numeric keypad. It provides the most cost-effective and user-friendly way to perform KVM control. Simply plug a compatible keypad into the designated USB port to control the KVM switch remotely.
