Adder AV4PRO-VGA-TRIPLE-US – AdderView 4 PRO Triple-Head VGA KVMA Switch

Product Overview

The Adder AV4PRO-VGA-TRIPLE-US is a 4-port triple-head VGA KVMA switch from the AdderView 4 PRO MultiScreen range, designed to control four multihead computers from a single high-resolution KVM console. Using Adder's True Emulation USB 2.0 technology, this multi-monitor KVM switch provides instantaneous, reliable hotkey switching across three VGA video heads per channel, plus independently switchable USB peripherals and audio. It is built for operator positions where each computer drives three displays and switching must never interrupt the workflow.

Product Description

The AdderView 4 PRO VGA MultiScreen (triple-head) connects four computers, each with up to three high-definition analog VGA outputs, to one console of three monitors, USB keyboard and mouse, switched USB devices, and speakers. An extended DDC EDID profile ensures the switched graphics card is always optimized for the connected screen, supporting resolution-intensive applications such as media and graphic design or detailed medical imaging.

True Emulation continuously presents the genuine character of the connected keyboard and mouse to all four computers simultaneously, so extra function keys, wheels, and buttons on enhanced devices keep working after every switch. Two independently switchable USB 2.0 channels and a separate audio channel let the operator type on one computer while scanning to a second, printing from a third, and listening to audio from a fourth.

Channel selection is available from keyboard hotkeys, a three-button mouse, front panel controls, or the optional RC4 remote, and the Options port accepts simple ASCII codes over RS232 for control-system integration. The same port synchronizes multiple AV4PRO-VGA-MS units to switch more than four video heads and handles firmware upgrades. The 2.5U metal chassis installs on a desk or in a rack with the optional RMK5PROMS kit, and the US model ships with a US mains lead. Related switches and cables are available in the Adder Technology collection at Creation Networks.

Frequently Asked Questions

How many monitors does each computer need for this model?
The TRIPLE model switches three VGA heads per channel. Each connected computer should have up to three VGA outputs; dual-head and quad-head versions are also made in the AV4PRO-VGA-MS range.

Will my keyboard's special keys work after switching?
Yes. True Emulation presents the genuine character of your keyboard and mouse to all four computers continuously, so extra keys, wheels, and buttons remain functional.

Can I integrate the switch with a room control system?
Yes. The Options port accepts simple ASCII codes over RS232 for remote switching, and echoes channel changes for synchronization with other units or RS232-triggered power switches.

Can I switch more than four video heads?
Yes. By linking Options ports, two or more AV4PRO-VGA-MS units can be switched in synchrony to support additional heads.

What operating systems are compatible?
The switch operates with all known software and operating systems, including Windows, DOS, Linux, Unix, BSD, Sun OS, macOS, and NetWare.

Are cables included?
The power adapter and US mains lead are included; VGA (VSC18), USB (VSC24), and audio (VSC22) cables are ordered separately. Creation Networks can quote a complete cable kit with your switch.
