The Digital and
Video Panel
The Digital and Video panel is shown in Figure 4-13. The panel is
invoked by pressing the DIG button on the panels menu. The panel
provides access to all digital patterns and video stroke functions and
their respective parameters. The Digital Patterns and Video waveform
modes are selected from the Main Panel. Note that the video function
mode utilizes both channels to operate in XY mode for the video drive.
Using an external utility, the digital patterns can be used with another
function on the other channel. The legal options for programming both
channels are summarized in Table 3-1.
