DKVM-4U
T
he D-Link DKVM-4U KVM switch is a handy device that allows you to control up to 4 PCs
using only one monitor, keyboard and mouse. The monitor and the two input devices are
connected directly to this KVM switch and not to the client computers. For office users with a
need for several PCs, this KVM switch box eliminates the need for several monitors,
keyboards and mice, saving the money and desktop space. The DKVM-4U is also a costeffective solution for control of several servers in a computer room, allowing an engineer to
handily manipulate all connected computers from a single monitor, keyboard and mouse.
Save Money and Space. The DKVM-4U allows you to control up to 4 computers from a single
keyboard, monitor and mouse, so you don't have to purchase a monitor, keyboard and mouse
for each PC. Your desktop will also look less chaotic. Your KVM switch can be placed
underneath your desk, with 4 sets to KVM cables connecting from this switch box to 4
computers. Each KVM cable set includes a video cable for PC's VGA connector, and a single
USB 2.0 cable for the PC's USB port. From the KVM switch box, you can connect to 2 USB
devices: a USB keyboard and a USB mouse. 2 sets of KVM cables are provided for ready
connection to 2 computers, the remaining KVM cables are optional.
Easy Control. You can switch quickly between the individual client computers by pushing a
button on the DKVM-4U or by pressing the hot keys on your keyboard. The KVM switch
confirms the switchover with an acoustic signal, and has LEDs indicating which PC is
currently being served by the console. All connected PCs are automatically scanned every 10
seconds, so your monitor, keyboard and mouse are updated whenever you switch to a
selected PC. CAPS LOCK, NUM LOCK and SCROLL LOCK key's status for each computer
is automatically recalled. The DKVM-4U guarantees that the client PC does not crash when it
is disconnected from KVM switch box.
High Monitor Resolution Support. The DKVM-4U is capable of supporting the most
demanding resolutions (VGA, SVGA and Multisync monitors) of up to 2048 x 1536 at 75Hz
refresh rate (bandwidth up to 400MHz) without any noticeable degradation in image quality.
