Introduction

OVERVIEW

The KVM-HDU-4 is a compact 4 port HDMI KVM Switch that features high speed video switching with HDMI Sink emulation technology, integrated 2-port USB hub, and Keyboard & mouse emulation for each PC input.
The switch supports ultrahigh resolution video including: 2560 x 1440, 2560 x 1600, and 3840 x 2160 @ 60 Hz.
Connected PCs do not experience any interruption to the video, keyboard, and mouse operation as a result of switching among the 4 inputs. All connected PCs continuously detect a keyboard, mouse and display regardless of the currently selected port.

The KVM-HDU-4 provides an integrated 2-port USB 2.0 Hub. This hub gets connected to the selected PC as the user switches among the 4 inputs. Users can connect other USB devices such as webcams, touch screens or printers to the KVM Switch. Devices plugged into the USB hub ports on the KVM Switch are only routed to the selected PC. When you select a new PC, those USB devices disconnect from the last PC and connect to the newly selected PC.
The front panel features 4 individual buttons for selecting inputs. LED indicators show the currently selected input port and the status of each input. Inputs can also be selected via hot-key sequences from the keyboard.
A power supply connection is not required. The KVM draws its operating power from the PC USB connections. However, a 5v power input connector is provided on the unit for special cases where power-hungry USB devices are used and/or the PCs do not meet the USB power sourcing specifications.

FEATURES

Supports high resolution video such as1920x1080, 2560×1440, 2560×1600 and 3840×2160.
4 Individual buttons on the front panel for selecting inputs.
Full plug-and-play support with USB keyboard, mouse, and connected peripherals.
Emulates keyboard, mouse and display for all PCs.

Provides USB 2.0 Hub that switches to the selected PC.
Computer OS independent – No driver or software required.
No power supply required for most applications.

Setup and Operation

The figure below shows the rear panel connections on the KVM Switch.
Cables are not included. For each input you must provide one HDMI and one USB cable. For the vast majority of KVM switching applications, the KVM-HDU-4 does not require any power supply since it draws power from the USB connections from the host PCs.
If the KVM-HDU-4 is used for switching video only with no USB inputs, then a power supply needs to be connected. This separately sold power supply is part number 511-U5V2AP5.

Setup and Operation

Front and Rear Panels

Press to select desired input.
Status of inputs:
- Off = No host/PC connected (or host is off)
- Solid On = Host connected but not selected
- Blinking = Host port selected
HDMI inputs – Connect to video sources (from each host PC)
USB inputs – Connect to host PC USB ports.
HDMI output – Connect to a display.
Dedicated keyboard and mouse ports
USB 2.0 Peripherals Ports – These ports are from an integrated USB 2.0 Hub and are routed to the selected PC’s USB port.
