General Button Rules
Please note the following general button rules:
• All button presses are registered (acknowledged) by the switcher when a selected button
lights. Pressing a button can switch a crosspoint (and affect the video output), perform a
transition, toggle a function, or have no effect (if the function is not valid for the current
setup).
• Buttons can be latching (in the case of valid crosspoints and “toggle” functions such as
key parameters), or momentary (in the case of transition buttons such as
CUT
).
• When you press a button and hold it down , the button lights to acknowledge the press.
After two seconds, the button reverts to its proper state for the selected mode. This
proper state could be on or off, depending upon the current setup.
• Pressing and holding one button, then pressing another is a valid mode. This sequence is
used for functions such as “favorite CG” and DSK setup. Details are provided in each
operational section.
Crosspoint Button Rules
When a button (or crosspoint) is pressed on the PGM , BKGD , PST and KEY buses, a video source is
selected. Video sources can be internally generated or derived from external sources (and connected to
the chassis via BNC).
Note
If you press a crosspoint button that is assigned to an external device,
the device control menu will be displayed.
