Appendix A •
Simple Instruction Examples
The tables that follow give examples of some of the ASCII codes that may be entered from a host device. The Switcher Response column shows what will be seen on the host’s screen. Appropriate response messages are also displayed on the System 4xi’’s LCD screen.
The resultant changes made by these commands will also show on the System 4xi Front Panel. Errors may occur under certain conditions, such as when trying to select a nonexistent channel, or trying to mute the projector when it is turned off, etc. Error codes are on the next page.
The first group lists commands for the display device (projector/monitor) and the second group lists commands for the switcher (System 4xi ). The Hex column gives hexadecimal equivalents for cases where the codes will be generated by another source.
