■ Preface
The WJ-MPU850 CPU is the Central Processing Unit for the System 850 Matrix Switcher. The System 850 Matrix Switcher is a CCTV surveillance system having multiple video inputs, multiple video outputs, and multiple control stations. The WJMPU850 is capable of controlling a maximum of 512 video input sources and a maximum of 64 video outputs, such as monitors, with 16 system controllers.
The WJ-MPU850 is a high-performance Intel X86 processor based computer running the OS-9 real time operating system allowing you to build up a redundant system of duplicate CPUs.
