The
shot panel allows complex switching of operations such as multi-level-breakaway
to be executed with a single button operation. The panel consists of a rackmount
keypad controller combined with a 12 button memory register selector. The keypad
and its display are used to set up breakaway crosspoint combination up to six
levels. Once these are set up, pressing "Learn" and one of the 12
memory buttons selects this combination and stores it for one button recall.
