The JideTech USB KVM Switch is a versatile device designed to manage multiple computers from a single console, offering various models to suit different connectivity needs, including HDMI and VGA KVM switches. This user manual covers five models: 21UA, 41UA, 94H2, 9138H, and 9116H, ensuring users can find relevant information for their specific product.

HDMI KVM Switch (Model 94H2 - 4 Port)

The 4-Port HDMI USB KVM Switch (Model 94H2) allows one USB console to control up to four HDMI-interface computers, DVRs, or NVRs. It supports superior video quality up to 4K (HDTV) / 4096×2160 at 60Hz, making it suitable for high-resolution displays. The switch is multiplatform compatible, supporting Windows 10/7/2000/XP/Vista, Linux, and Mac operating systems. It offers plug-and-play functionality, simplifying setup, and supports HDCP and auto EDID without emulation. A notable feature is its auto-detection capability: if one computer is powered off, the switch can automatically switch to the next powered-on computer. This feature is off by default and can be enabled by following specific instructions in the manual. The device also includes a memory function to retain settings in case of power-down and supports independent mouse and keyboard switching, even without a USB signal input, allowing for flexible control. An Auto Scan Mode is available for monitoring all connected computers, DVRs, or NVRs, and the switch is equipped with a USB 2.0 Hub for additional peripheral connectivity.

Keyboard Hot-key Operations (Models 9138H/9116H)

The hot-key operations for the 8/16 port models are largely the same as the 4-port model, including functions for switching ports, toggling auto-scan, setting scan intervals, controlling beeping sounds, managing detection functions, resetting the KVM system, addressing mouse/keyboard issues on different OS, restoring hotkeys, and resetting factory settings. The only difference is the extended range of port IDs (1 to 16) for switching.

Notes for HDMI KVM Switches

N refers to the computer's Port ID number (1, 2, 3, 4 for 4-port; 1 to 16 for 8/16-port) or a number from 8 to 999 for scan interval settings.
Activating auto-scan can be interrupted by pressing any key on the panel.
If a computer enters sleep mode, users must press the computer's power button to wake it up. It is recommended not to set computers to enter sleep mode when using the KVM.

LED Indicators (Models 9138H/9116H)

The LED indicators are identical to the 4-port model: orange lightning for the current operating port, green hotkey lightning, and SCAN lightning for auto-scan mode.

Turn on the second computer and wait for startup to complete. The installation is then complete.

Troubleshooting (Models 21UA/41UA)

The FAQ section addresses common issues for VGA KVM switches:

Power Supply: The USB KVM switch does not require an external power supply; it draws power from the computer's USB connection.
