Keystone
KST Keystone
Use KST to correct vertical keystone (14-50) so that the sides of the image do not slope away
from each other, and the image is rectangular. The default value is 32 (no keystone).
For advanced 2D keystone using the Warp Module, see Warp Keystone Corners (WKC).
LBL Left Blanking
Use LBL to blank the left edge of the image (0-1000). The amount of blanking feasible depends
on the incoming source data.
LCB Lens Calibrate
LCB forces the projector to calibrate the lens/motors and is intended for use in conjunction with
Wolf Cinema's Lens VariScope System (LVS). Lens Calibration is not necessary if LVS is not
used.
LCB provides three types of calibrations to be performed. A Reference calibration locates a
positional reference point for repeatable motor positioning. A Motion calibration calculates
and sets motion parameters that optimize individual motors response for accurate positional
placement. A Full calibration executes both of these calibrations.
If LVS has already been enabled (refer to LVS command), a Reference calibration will be
performed when the projector is powered up. Motion calibration only needs to be done once when
LVS is initially enabled because the results are retained in memory for future use. Therefore, if
LVS is to be used, it is only necessary to perform motion calibration once.
LVS can only be enabled if both calibrations have been performed at least once. If LVS is
disabled, neither calibration is necessary.
Refer to the tables below for the parameters to control the LVS calibration process.
Command Values:
Parameter Description
1 - Relative Calibrate Motor Zero Reference Position
2 - Manual Calibrate Motion Parameters for Lens Motors
3 - Calibrate Calibrate both Reference and Motion Parameters
Query Values:
1 = calibration has been done, 0 = calibration has not been done
Parameter Description
Reference Calibration Motion Calibration
Examples:
(LCB 3) Stop Horizontal Movement, Lens will not stop until this command is issued or
the end stop is reached.
(LCB?) Query the current status of calibration, responds with (LCB!1 0) indicates
that reference is calibrated but motion parameters are not.
