The Extron DMS Series Modular DVI Matrix Switchers represent a new level of matrix switching for DVI. They combine the simplicity and reliability of a fixed I/O matrix switcher with the convenience and flexibility of a modular matrix switcher. DMS Series matrix switchers accept any combination of available DMS DVI or DMS Fiber matrix boards. Input and output boards are available in 4-port input, 4-port output, and 4x4 I/O versions, providing various I/O size combinations with sizes from 4x4 to 36x36, depending on the DMS Matrix Switcher Frame selected. The DMS Series is ideal for a wide range of applications that require routing of high-resolution DVI digital video signals without copy protection.
