2 Port USB VGA KVM Switch with DDM Fast Switching Technology and Cables
Product ID: SV231USBDDM
The SV231USBDDM 2-Port USB VGA KVM Switch lets you control 2 VGA, USB-equipped PCs using a single
peripheral set at high-definition VGA resolutions up to 1920x1440.
The included KVM cables provide a ready-out-of-the-box solution, USB Dynamic Device Mapping (DDM) works to
reduce switching lag-time, and Display DataChannel (DDC) improves overall compatibility with your connected
display and input devices.
For the next level in KVM performance, this VGA KVM switch integrates multi-core dedicated processing per channel
and innovative, USB DDM technology that enables you to quickly switch between connected computers with
next-to-zero delay. DDM maintains a constant communication channel between your USB peripherals and connected
systems, avoiding the time necessary for your systems to re-recognize the devices when switching.
In addition to faster switching, the KVM offers All-time Display Data Channel (Full DDC) technology to maintain
proper display detection among connected systems, a simple one-touch button for hot-key selection and an
integrated 2-port USB hub allowing you to share additional peripherals.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
