Introduction

The SV231HDMIUA 2-port USB HDMI® KVM Switch lets you control two USB-enabled

multimedia computers or devices with HDMI video interfaces, using a single peripheral

set/console (USB keyboard, mouse, monitor, speakers and microphone).

A highly versatile KVM solution, the USB HDMI KVM Switch features an integrated

2-port USB 2.0 hub that lets selected computers access shared high speed USB devices,

eliminating the cost of duplicate USB peripheral purchases.

Ensuring high quality video capability, the HDMI KVM switch supports HD resolutions

of up to 1920 x 1200. Oering genuine digital signal transmission over the cable, this

switch can be used to share one HD panel between multiple HDMI sources such as Blu-

Ray players, Video Game consoles and HD media centers.

The switch also supports audio and microphone switching functions and allows you to select

connected computers, USB device hub ports and audio/mic channels either simultaneously

or independently using either front-panel push-buttons or keyboard hotkeys.

Instruction Manual

HotKey Control

A Hotkey command is a short keyboard sequence for selecting a computer, activating

computer scan, etc. A hotkey sequence starts with two left <CTRL> keystrokes

(successively within 0.2 seconds) followed by one or two more keystrokes. A built-in

tone generator creates a high-pitch beep for correct hotkey command; otherwise, one

low-pitch beep is generated for errors and the bad key sequence will not be forwarded

to the selected computer.

NOTE: Press and hold Left <SHIFT> and press <NumLock> twice, then release <SHIFT>

followed by pressing left <CTRL> once, which will enable / disable the hotkey feature.

To select a computer:

Left <CTRL> + Left <CTRL> + <1>

(Example: Selects the computer at port 1.)

Left <CTRL> + Left <CTRL> + <2>

(Example: Selects the computer at port 2.)

NOTE: Do not use the keypad on the right-side of the keyboard.

Auto Scan

The KVM automatically scans through the powered-on computers in sequence on a

xed time interval (see Scan Time below).

To start Auto Scan:

Left <CTRL> + Left <CTRL> + <F1>

To abort the Auto Scan mode, press the left <CTRL> key twice.

NOTE: When Auto Scan detects any keyboard or mouse activity, it suspends the

scanning till the activity stops; it then resumes with the next computer in sequence.

The length of the Auto Scan interval (Scan Rate) is adjustable, see below.

Instruction Manual

Manual Scan allows users to manually switch back and forth between powered-on computers.

Left <CTRL> + Left <CTRL> + <F2>

To select the previous or the next computer, press <UP> or <DOWN> arrow keys. To

abort the Manual Scan, press any other key.

Scan Time

Four options are available for users to set the Scan Time duration, it Includes 3, 8, 15

and 30 seconds.

Note: Scan Time is set to 3 seconds by default.

To adjust Scan Rate, set the scan time of duration before switching to the next computer:

Left <CTRL> + Left <CTRL> + <F3>

The KVM Switch generates 1 to 4 beeps indicating a scan time duration for 3, 8, 15 or

30 seconds respectively.

Audio Lock

There are two options for Audio Lock: ON and OFF. When ON, audio selection follows

computer selection. When OFF, the current port’s audio is used for all other ports. It

is useful if you want to listen to a particular computer’s audio signal while operating

other computers.

Left <CTRL> + Left <CTRL> + <F5>

The KVM switch beeps once or twice corresponding to ON and OFF respectively.

To change which port the audio is following to the currently selected port, press the

following hotkey:

Left <CTRL> + Left <CTRL> + <A>

Alternative Hotkey Commands

In addition to the Left <CTRL> + Left <CTRL> hotkeys, there are two alternative hotkey

sequences available.
