C3: The OPEN DOUSER AND CINE Command [OP]
This operational command opens the douser. The film must be moving at cine speed for this command to take
effect; if the projector status is not equal to 1, the OPEN DOUSER command is ignored.
ENTRY:
<CMD-C>, <3>
CODE:
C3
ACTION
S:
Open the douser and put projector into cine mode.
STATUS: Set to 3.
C4: The CLOSE DOUSER AND SLEW Command [OP]
This operational command closes the douser. The douser also closes automatically when the EOF marker is
detected. Since the douser is open only when the film is moving at cine speed, a CLOSE DOUSER command
has no effect unless the status value is 3.
ENTRY:
<CMD-C>, <4>
CODE:
C4
ACTION
S:
Close the douser and put the projector into slew mode.
STATUS: Set to 1.
C5: The CLEAR CUES Command [OP]
This operational command is used to erase all previously programmed BOF and EOF cue points.
ENTRY:
<CMD-C>, <5>
CODE:
C5
ACTION
S:
Erases pre-programmed cue points for all shows.
STATUS:
Unchanged.
C6: The AUTO LOG Command [OP]
This operational command causes the projector to do a normal CUE and then high speed forward to the end of
the reel, logging EOF and BOF tapes as it moves. The REEL TIMES are displayed, logged, and latched, so that
they may be recorded manually if desired. If fewer than the maximum shows are to be programmed, the STOP
button terminates the command.
To perform auto logging, the projector must be in the READY mode, and the film must be loaded in the projector
so that the BOF tape for Show #1 is above the gate or on the supply reel. Then follow the command sequence
described.
BOF and EOF tapes must be affixed to the film for all shows that are to be
programmed.
