Frequently Asked Questions - SV431DDUSB StarTech.com

How do I switch between computers using the front panel?

Press the PC port selection button (labeled PC1, PC2, etc.) on the front panel. The green LED will indicate which computer is currently active. If binding is enabled, the USB hub and audio will also switch to that computer.

What is the default hotkey sequence to select a computer?

Press the Scroll Lock key twice within 2 seconds, then press the port number (1-4). For example, Scroll Lock + Scroll Lock + 1 selects computer 1.

Can I use different types of DVI cables for the same KVM?

It is recommended to use the same DVI cable type (DVI-I or DVI-D) for both PC-to-KVM and KVM-to-monitor connections on a given port. Mixing DVI-I and DVI-D on the same port may cause incompatibility.

How do I bind or unbind computer selection and audio switching?

By default, computer and audio/mic control are bound. To unbind, press Scroll Lock + Scroll Lock + B (for 'unbind computer and audio'). To re-bind, press Scroll Lock + Scroll Lock + B again.

Does the KVM require driver installation?

No. The KVM uses standard USB HID drivers already present in all operating systems that support USB. Simply connect the keyboard and mouse to the console USB ports.

What is the maximum video resolution supported?

For VGA: up to 2048x1536, for DVI: up to 1920x1200. Note that the source computers must output the same resolution for proper switching.

Can I share USB peripherals like a printer between computers?

Yes. The KVM includes a 2-port USB 2.0 hub that can be shared among connected computers. The hub port selection can be bound to computer selection or controlled independently via hotkey.

How do I change the hotkey preceding sequence from Scroll Lock to another key?

Press Scroll Lock + Scroll Lock + S, then press the desired key (Caps Lock, ESC, F12, or Num Lock). You will hear a high-pitch beep confirming the change.

What should I do if the KVM does not detect my keyboard or mouse?

Ensure the keyboard and mouse are connected to the console USB ports (marked with keyboard/mouse icons). If using a wireless set, ensure the receiver is connected. Try a different USB keyboard/mouse to rule out compatibility issues.

Is this KVM cascadable to add more computers?

No, the SV431DDUSB is not cascadable. For more than 4 computers, consider a different KVM model or a larger setup.

Introduction

The StarTech.com SV231DDUSB 2-port Dual Monitor KVM Switch (DVI+VGA) offers a complete dual display multimedia switching solution, allowing users to control 2 computers using a single USB mouse and keyboard peripheral set.

With support for high-resolution video interfaces, the versatile dual monitor KVM switch provides 1 VGA (analog) and 1 DVI-I port per computer connection, as well as audio switching capability between connected computers.

Delivering the capability you need for virtually any application, the dual monitor KVM switch features an integrated 2-port USB hub that allows connected USB 2.0 peripherals to be shared between connected computers, eliminating the need to purchase duplicate peripherals.

Suitable for any workspace, the dual monitor KVM switch features a compact, desktop KVM design and features a rugged metal chassis that helps ensure durability.

NOTE: While both DVI-I (analog mode) and DVI-D (digital only) are supported by the KVM, both source PCs must output the same signal type for proper switching. It is recommended wherever possible to use DVI-D cables across all PC to KVM and KVM to Console connections. If necessary, please contact our technical support team for assistance identifying your source.

The 2-port DVI+VGA dual monitor KVM switch is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Installation

Hardware Installation

NOTE: Prior to the installation, please power off all devices that will be connected to this system.

1. Place the KVM switch in close proximity to the keyboard, mouse, and monitor(s) you wish to use as the console controls.
2. Connect the USB keyboard, mouse, speakers and microphone (if applicable) to the KVM switch.
3. Connect the DVI monitor into the Console's DVI connector.
4. Connect the VGA monitor into the Console's VGA connector.

OPTIONAL: Connect any other USB peripheral you wish to share between the connected computers/devices to the extra USB Hub port on the Console side.

1. Use male-to-male video cables to connect the DVI and VGA connectors on the computer's video card, to the DVI and VGA ports for one of the KVM's PC ports (i.e. PC1).

NOTE: Do not mix different types of DVI cables (DVI-I, DVI-D) on the same KVM switch.

1. Use a USB type A-B Cable to connect the KVM's USB port (type B, square connector) for the PC port used in the previous step, and the USB port on the computer (type A, flat connector). If using audio, connect 3.5mm mini-jack cables from the PC port to the sound card.

NOTE: DVI + USB + Audio KVM combo cables are also available which can be used in place of separate individual cables (e.g. StarTech.com ID: DVI4N1USB6).

1. Repeat the previous two steps for each PC port on the KVM switch, or each computer you wish to use on the KVM switch.

2. Connect the external power adapter from a wall outlet to the power connector on the rear panel of the KVM switch.

3. Power up the first computer/device and wait for it to fully boot and test keyboard/mouse functionality.

Driver Installation

No driver installation is required for the KVM switch, as the keyboard/mouse use USB drivers that are already installed on any operating system that fully supports USB.

Operation

Port Selection Buttons

The Front Panel buttons allow direct control over KVM switch operation and channel switching. Simply press the PC button for PC port switching. If binding is enabled between PC / USB hub port control / Audio and Mic switching, they will be jointly selected at the same time). If you wish to enable the binding of PC / Hub Port control / Audio and Mic switching, see "Hotkeys" section.

Port Selection LEDs

The green 'PC' LED indicates the currently selected computer that has keyboard and mouse, audio and video access. The red 'HUB' LED indicates the currently selected computer that has access to the USB hub ports.

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 (Scroll Lock) keystrokes (successively within 2 seconds) followed by one or two more keystrokes. A built-in tone generator creates a high-pitch beep for correct hotkey command; otherwise, errors and bad key sequences will not be forwarded to the currently selected computer.

The two proceeding keystrokes can be changed if desired. Press + + , which will be followed by two beeps indicating readiness for selection of a new preceding sequence, or press and hold down the last front-panel button (Button 2 on SV231DDUSB, Button 4 on SV431DDUSB) until you hear two beeps, then release the button.

Select and press the key you would like to use as your preceding sequence (Scroll Lock, Caps Lock, ESC, F12 or Num Lock) and you'll hear a beep for confirmation. The new preceding sequence can now be used to execute hotkey commands.
