OPERATION
In some early versions of the 4025 firmware DIP Switch #5 on the 615 module
was used to set the PLAY WINDOW. It is used for other purposes now and
should be set in accordance with the chart in Figure 6-6.
The KK PLAY WINDOW sets how many film frames of
difference are allowed between the KeyKode numbers and the
bi-phase based film edge numbers (when the telecine is in
PLAY and the KKJAM mode is set to PLAY or ALWAYS).
When this limit is exceeded the bi-phase based edge numbers
will be updated from the KeyKode numbers. The factory default
setting of 00 means that any differences between the KeyKode
and bi-phase based numbers (when the telecine is in PLAY) will
cause a KeyKode jam to occur. Set this value to 01 or 02 when
using telecines with Scantrack and low tach rates. Use the
keys to adjust. See section 3.4.1 for a description of the KK
JAM PLAY and ALWAYS modes.
3.7.2
Controlling the KeyKode Jam when the Telecine is in Shuttle
speeds
SHUTTLE WINDOW Is used to adjust accuracy of the KeyKode jam
function when the telecine is not at locked play speed, and
when the KK JAM mode is set to ALWAYS. (When the KK JAM
mode is set to NEVER, ONCE or PLAY this parameter is
ignored.) See section 3.4.1 of the manual for a description of
the KK JAM ALWAYS mode. The KK SHUTTLE WINDOW sets
how many film frames of difference are allowed between the
KeyKode numbers and the bi-phase based film edge numbers
(when the telecine is in SHUTTLE).
exceeded the bi-phase based edge numbers will be updated
from the KeyKode numbers. The factory default setting of 30
means that differences between the KeyKode and bi-phase
(when the telecine is in SHUTTLE) or more than 30 film frames
will cause a KeyKode jam to occur. Use the
adjust.
3.7.3
Selecting How Soon the 4025 Detects Loss of KeyKode
CHECK DELAY
warning in the VCG becomes active when KeyKode is not
present, and the KEYINFO mode is set to INFO CHECK. The
CHECK DELAY WINDOW sets how many feet of film can pass
without reading KeyKode before the INFO CHECK warning in
the VCG is activated. See section 3.4.2 in the manual for a full
description of the INFO CHECK DISPLAY. The factory default
setting of 10 means that ten feet of film without reading
KeyKode will trigger the KeyKode check display of the VCG.
