By default, the Windows installation creates a C:\MTRX50 directory and places two icons (MATRIX Switcher+ Control Program and MATRIX Switcher+ Help) into a group or folder named “Extron Electronics”. The program was designed to control most Extron matrix switchers, but its operation is limited to the features and configuration of your switcher.
im Vertrieb von CAMBOARD Electronics Using the software Many items found in the Matrix Switcher+ Control Program are also accessible via front panel controls (see chapter 3, Operation) and under SIS control (see chapter 4, Programmer’s Guide). The Matrix Switcher+ Help Program provides information on settings and on how to use the control program itself.
