4-Port KVM Switch with 4K HDMI & USB 2.0

1.0 Introduction

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.

3.0 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.

Front and Rear Panels

1. Press to select desired input

2. Status of inputs:

•Off = No host/PC connected (or host is off)

•Solid On = Host connected but not selected

•Blinking = Host port selected

3. HDMI inputs – Connect to video sources (from each host PC)

4. USB inputs – Connect to host PC USB ports

5. HDMI output – Connect to a display

6. Dedicated keyboard and mouse ports

7. 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

8. Optional Power Input – For KVM applications, no external power

would be required for most applications.

3.1 Hotkey Sequences

•To select inputs press the following key sequence

(1 represents the desired input channel in the example below)

•To start SCAN MODE press the following key sequence

Note: (1) You must complete the key sequence within 3 seconds.

(2) In SCAN mode the switch automatically cycles through all

inputs one at a time. Each input is shown for 10 seconds. To stop

the scan mode, press any key.

3.2 Smart EDID management

The KVM Switch reads the EDID of the connected display and uses it on all

its inputs. If there is no monitor at the output, the Switch will recall and

use the EDID of the last monitor that was plugged.

4.0 Troubleshooting

If you are experiencing problems getting the switch to work properly,

please use the following troubleshooting suggestions.

Make sure that all of the connections are solid.

Check the LEDs on the front panel.

Disconnect power and all USB inputs and reconnect them

If you still are not able to get the system working properly, contact Hall

Research support via email or fill out the form on support page of

http://www.hallresearch.com.

Please give a detailed description of the issue and the troubleshooting

steps you have taken along with the serial number.

Do not open or try to repair the unit yourself, as this will void your

warranty.
