ADDERView PRO 4-Port USB DVI-I KVM Switch
The AdderView Pro AV4PRO-DVI-US is a professional grade KVMA switch delivering ultimate flexibility for users who wish to share a high resolution screen and modern USB peripherals between a multiplicity of computers.
The AV4PRO-DVI is designed to enable four computers to be controlled from a single high resolution KVM console using either dual link DVI or high definition analogue video links. The switch makes use of Adder's True Emulation technology which enables USB HID devices to be continuously emulated to each computer. This unique technology enables instantaneous and reliable hotkey switching whilst also supporting the extra keys and features of enhanced keyboards and mice. Furthermore, the AdderView includes two independently switchable USB 2.0 channels and an audio channel, giving the user the flexibility to attach selected peripherals to different computers.
- Access up to four computers with one display, keyboard and mouse user station
- High definition dual link DVI-I video up to 2K (2048 x 1080) for film post production or WQXGA (2560 x 1600) for medical imaging
- USB keyboard & mouse with support for almost any keyboard and mouse, graphics tablet, jog shuttle, joystick, 3D explorer, etc.
- USB 2.0 Hub (2-Port) with broad high speed device support
- Stereo audio support via 3.5mm auxiliary jacks
Adder AV4PRO-DVI Features
True USB 2.0 emulation
Unlike most KVM switches, which only support the most basic keyboard and mouse features, Adder's revolutionary 'True Emulation' allows you to use the extra function keys, wheels, buttons and controls that are commonly found on modern keyboards and mice. You can also use any other USB interface device including graphics tablets, jog shuttles, joysticks, 3D explorers, and wireless bluetooth keyboard & mouse*.
Independent USB & Audio device switching
The AdderView Pro AV4PRO-DVI includes two independently switchable USB 2.0 channels and an audio channel, giving the user the flexibility to attach selected peripherals to different computers. For example, 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.
Broad High Speed device support - Transparent USB 2.0 Hub
An integrated transparent 2-port USB 2.0 hub allows a vast range of USB devices can be connected to the AV4PRO-DVI from non standard keyboard / mouse devices to flash drives, printers and scanners.
Fast & Reliable Switching
Country code reporting, extended DDC EDID profile and continuous keyboard and mouse emulation ensure faultless operation. The USB 2.0 switching action has also been carefully engineered to ensure maximum computer reliability when connecting and disconnecting USB devices.
Channel selection options
The AdderView Pro AV4PRO-DVI can be switched using the front panel buttons, selectable keyboard hotkeys, 3 button mice, an On-Screen-Display (OSD), or using simple ASCII codes via serial RS232. Optionally, you can also use the RC4 remote switch to make your selection. These switching options allow you to rapidly reassign connected devices to any of the connected computers.
The AV4PRO-DVI works with all known software and computer platforms, with PS/2, USB and Sun, including Windows (all), DOS, Linux, Unix, BSD, all Sun OS, all Mac OS, NetWare, etc.
Plug and Play
AdderView Pro KVM devices are delivered in a zero configuration state so you can plug them in and start working on them straight away. There is no need for drivers or software to be installed.
Serial RS232 port for control, synchronization and upgrade
- Remotely switch AV4PRO-DVI using simple ASCII codes
- Integration with RS232 controlled power switches to provide a complete hard reboot function
- Flash upgrade
Expand up to a 5-monitor KVM Switch
AV4PRO-DVI can be linked with another Adder AV4PRO unit to create up to a 4-port dual-monitor, triple-monitor, quad-monitor, or 5-monitor KVM Switching system, by using a VSC41 synchronisation cable.

Answer: Thank you for your inquiry,
For consistent Enumerated USB switching and video EDID (essentially video resolution and frequency settings), Adder recommends to disconnect power from the AV4PRO-DVI and the re-connect it after changing user console or computer interface (in this case, connecting / disconnecting laptops). That is all you need to do; During the power up, the KVM will automatically ping and configure each attached device for use.
Please refer to the Adder AV4PRO-DVI Manual for further information on configuring and operating the unit.
Note, it may also be possible for your to swap-out the laptops without power cycle - see below for procedure. However, this second procedure is hypothetical and the AV4PRO-DVI is not designed for 'Hot-Swapping'; We are unable to guarantee this method to work at all, or without any loss in functionality.
- Switch ports to a source you are not disconnecting,
- Swap-out the laptop
- Switch back to the original port. This switching step is needed for initializing the Enumerated USB.
- Now you can click 'F' and then '2' to refresh the display EDID information to match the video to the source. If the laptops are the same, using the 'stored EDID' feature by clicking 'F' and then '3', instead of the previous 'refresh EDID', may also help you in quickly restoring the video settings.
Question: How do you get 2 USB (keyboard and mouse) to 1 USB type b?
Answer: Thank you for your inquiry,
To pass the keyboard and mouse signals from the user station to the source PCs, you connect a USB A-to-B cable from the KVM switch to each of the source PCs (the B-ends into the KVM switch, and A-ends into the computer). The cleanest way to do this is to use Adder's USB + DVI combo KVM cables which include connections for the video and USB.
On the user station side, you simply plug in the cables from your keyboard and mouse into the KVM switch user station ports.
