Lightware MX-CPU2 board is a direct replacement of the original CPU board housed in Hybrid Modular matrix frames. CPU board that allows multiple TCP/IP connections, extra I/O, and more advanced error handling. It has been upgraded with several unique features to help improve our new range of digital video/audio routing and extension systems. Additional input and output ports fully support DVI and 3D HDMI signals with or without HDCP encryption. The test input and preview output ports turn an existing 16x16 matrix to a 17x17 and an existing 32x32 to a 33x33. Upgrading an existing router with MX-CPU2 is a simple board replacement, with only two screws to undo.
