Lamp Intensity Calibration (LCA)
DESCRIPTION
This control is used to calibrate (correlate) the intensity feedback mechanism to footlamberts. Note the minimum/maximum
power are used to pick two points on the curve. These points will not stay consistent over the life of the lamp, but the
conversion algorithm will extrapolate the conversion beyond the range of the two end points. Note: changing the lamp or lamp
alignment will require re-calibration.
SUBCODE
MAXF
MAXS
MINF
MINS
None
EXAMPLES:
(LCA+MINF 10) set 10 footlamberts as measured brightness at minimum lamp power
(LCA+MINF?) get footlamberts on minimum lamp power
(LCA+MAXS 15000) set 15000 as reading value from the light sensor on maximum lamp power
Lens Reset (LCB)
DESCRIPTION
Reset lens mount system to home position at horizontal and vertical axes, reset zoom, and focus lens to home position.
Depends on ILS and ALC configurations, when ILS and ALC are both turned ON, when system was powered on LCB will be
run automatically at all axes.
SUBCODE
None
EXAMPLES:
(LCB 0) Cancel lens reset
(LCB 1) Run lens reset on horizontal axis
(LCB 2) Run lens reset on vertical axis
(LCB 3) Run lens reset on zoom lens
(LCB 4) Run lens reset on focus lens
(LCB 5) Run lens reset on all axes
(LCB ?) Return current lens reset status, 0: stopped, 1-4: resetting on current axis
LUT CLUT Control (LCT)
DESCRIPTION
Set Look up Table (LUT) Color Look Up Table (CLUT) file for the specified channel. The CLUT is used during color process-
ing in the cinema electronics.
