3-14
Section 3 Ð Editor Interface Commands
Pushbutton Numbers
The pushbutton numbers supported by these commands cover the transition
subpanels and the timeline run control subpanel. These numbers are speciÞed in
Table 3-10, ÒTransition Subpanel Pushbutton Numbers,Ó on page 3-15 and Table 3-
11, ÒKeyframing Pushbutton Numbers,Ó on page 3-16.
The original intent of the switcher design team was to extend the range of these
commands to cover the pressing of all buttons on the control panel. However, over
time, it became clear that a better serial interface to provide for editors is the
parameter-based command set (PBCS). This new command set directly sets the
internal switcher state irrespective of whatever control panel may, or may not, be
attached. So, for backward compatibility, a further set of pushbutton numbers is
supplied for the wipe subpanel in Table 3-12, ÒObsolete Pushbutton Numbers Ð,Ó
on page 3-17. Although these commands do work, it is recommended that wipes
be set by using the Write Wipe Pattern (C8) Command on page 3-21 or the PBCS
described in Section 4.
WARNING
Specifying an invalid pushbutton number may produce an
unpredictable result.
Also, please note that on the M/E Transition Panel (and DSK for 4000-2A):
¥ MIX and WIPE are mutually exclusive. Turning on one turns off the other.
