Section 2 — Control Panel Descriptions
INH MASK delegates the Mask subpanel controls for adjusting the
inhibit mask. The actual selection of mask inhibit is performed on
the Keyer subpanel (see the MASK INH discussion under the Keyer
panel description).
FORCE MASK delegates the Mask subpanel controls for making
adjustments to a forced mask. The actual selection of force mask is
performed on the Keyer subpanel (see the FORCE MASK
discussion under the Keyer panel description. The DSK cannot
perform a forced mask.
Auto delegation of the Mask subpanel may occur when other
buttons on the control panel are pressed. (Refer to the Auto
Delegation discussion earlier in this section.)
Mask Source Selection
The top row of buttons select sources that determine the shape of
the mask. These buttons are mutually exclusive and one is always
active.
BOX uses a rectangular box generator for the mask. The box is
completely independent of the wipe systems. The four knobs at
the top of Masks subpanel determine the position of the four sides
of the box. The box mask has hard edges. Each keyer has its own
box, so it is possible to have up to six differently sized box masks
in use at a time. A box mask is the only type of mask available on
the DSKs.
PRI WIPE selects the primary (transition) wipe generator to
produce the mask. The primary wipe generator in the same M/E
provides the mask signal. Wipe subpanel controls select the
pattern, size, position and edge softness. This is not available on
the DSKs.
SEC WIPE selects the secondary (optional) wipe generator to
produce the mask. The secondary wipe generator in the same
M/E provides the mask signal. If the secondary wipe option is not
installed, the pattern shape and position are the same as the
