The ADDERView® 4PRO-DVI (AV4PRO) is designed to enable four computers to be controlled from a single high resolution KVM console using either Dual-Link DVI or high-definition analog video links.
The switch makes use of Adder’s USB True Emulation technology which enables USB HID devices to be continuously emulated to each computer. This unique technology enables instantaneous and reliable hotkey switching.
Two independently switchable USB2.0 channels and an audio channel give the user the flexibility to attach selected peripherals to different computers.
Models are available supporting single, dual, triple, or quad head DVI computers.
Dual link DVI-I with extended profile DDC EDID: The ADDERView® 4PRO-DVI (AV4PRO) features full dual link DVI video delivering up to 4 megapixel resolutions at 60Hz. The AV4PRO features DVI-I, allowing you to choose from digital or analog sources. The extended DDC (Data Display Channel) EDID (Extended Display Identification Data) profile ensures that the switched graphics card is always optimized to work with your screen. The dual link DVI capabilities enable users to work at high resolutions including 2K (2048x1080) for film production and WQXGA (2560x1600) for detailed medical imaging.
True Emulation USB2.0 technology: The AV4PRO features Adder’s advanced True Emulation USB technology. This provides an instantaneous and reliable switching action and makes keyboard hotkey and mouse switching possible. It emulates the true character of the connected devices to all the computers simultaneously, allowing you to use the extra function keys, wheels, buttons and controls that are commonly found on a modern keyboard and mouse.
Independent simultaneous device selection: The switch enables you to use the KVMA console to work on one computer whilst your USB peripherals are connected to other computers and your speakers are playing music from yet another. You can switch all connected devices to any one of the connected computers, as with most other KVM switches.
Channel selection options: The AV4PRO can be switched using selectable keyboard hotkeys, a 3 button mouse or the front panel controls on the unit. You can also use the ADDER® RC4 remote switch. These switching options allow you to rapidly reassign connected devices to any of the connected computers.
Broad USB2.0 hi-speed device support: A vast range of USB devices can be connected to the AV4PRO from non-standard human interface devices (HID) to printers and scanners. This flexibility allows you to scan a set of documents onto one computer whilst working on another and printing from yet another, all at the same time. The USB2.0 switching action has been carefully engineered to ensure maximum computer reliability when connecting and disconnecting USB devices.
Options port for control, synchronization and upgrade: An ‘Options’ port enables the AV4PRO to be remotely switched using simple ASCII codes. When the channel is switched, the same ASCII codes are echoed to the ‘Options’ port. By linking the ‘Options’ ports, two or more units can be switched in synchrony to create a multi-video head switching system. The port enables a 4 button switch unit (ADDER® RC4) to be used with the AV4PRO. The same port can also be used to upgrade the firmware.
