Use the GPI Inputs Menu to set GPI assignments for signals that 
can be used to trigger Model 2200 functions. These assignments 
must correspond to the physical GPI connections described earlier 
in this section.

Eight GPI inputs are provided. All of these accept pulse-type GPI 
inputs except Aux Tally Back, which is level-sensitive.

From the Inputs Menu, press the 

 button to select the 

GPI Inputs Menu. (The first time you do this no functions will 
appear in the second column of the menu table.)

The types of GPI assignments currently available are 
Miscellaneous (Aux Tallies), Keyframe Effects, Auto 
Transitions, Cuts, E-MEM registers, and Frame Stores, as 
indicated by the button labels at the bottom of the display 
window.

One of these functions is always selected. The selected 
function is indicated in parentheses under the 

 knob label.
