Making Connections Chapter 2 _______ Although all three outputs may be connected at the same time, only one can be active at one time, as determined by the input format. In a typical installation, an LCD projector may have inputs for all three formats. In such cases, each of the three System 5 outputs would be connected to the same projector. 11 R, G, B, H/HV, V BNC connectors, for RGBS or RGBHV output. The green LED indicates when the selected input is RGB format (PC1, PC2 or PC3) and this o

Operating the System 5cr Chapter 3 Configuration Setup from the Front Panel For the System 5 switcher to control other equipment in the A/V system, it must be configured from the front panel, or through an RS-232 device. This cannot be done from an IR 40 or SCP 100. See Chapter 4 for Windows® Control program and Appendix A for RS-232 instructions. Infrared Programs and Libraries Extron provides a library of drivers for most projectors. To download a driver from the library, see the procedure
