Lens Vertical Offset Adjustment (LVO
Adjust lens offset to specific vertical position with a specific direction. NOTE: This command can only be used to
update the current ILS file. Changing the vertical offset for the current channel will change the vertical offset for
any channel using the same ILS file.
Use command without subcode:
• If ILS is ON, motor will move to specified steps and save data to the active channel.
• If ILS is OFF, motor will move to specified steps. Do not save data to the active channel.
SUBCODE DESCRIPTION OF USE
Motor backlash in negative direction. Read-only.
BACN
Motor backlash in positive direction. Read-only. Set only command.
BACP
Calibrate travel range and backlash on specified. Only valid parameter for this command is 1. Set only
CALB
command.
Replace Cxxx with the channel number. Valid range is 101-164.
Cxxx
Moving lens mount to a specified vertical position with a specified direction.
NONE
Motor moving range in negative direction. Read-only.
RNGN
Motor moving range in positive direction. Read-only.
RNGP
Move motor to the center flag then move back to current position. Only valid parameter for this command
RSET
is 1. Set only command.
Start motor moving in specified direction, where direction can be (-1, 1). Write-only for v1.3 or newer.
STRT
Stops the motor. Write-only for v1.3 or newer.
STOP
Moves the motor a given number of steps based on the current location. Write-only for v1.3 or newer.
MOVR
EXAMPLES:
(LVO 500 1) Move lens to position 500 along vertical axis with positive approach
(LVO 500 -1) Move lens to position 500 along vertical axis with negative approach
(LVO+C101 -500 1) Set lens vertical position for channel 1 to -500 with positive approach
(LVO ?) Return current motor position along vertical axis and direction
(LVO+CALB 1) Calibrate the vertical axis
(LVO+RSET 1) Reset the vertical axis
(LVO+STRT 1) Starts motor moving in positive direction
(LVO+STOP) Stops motor
(LVO+MOVR -100) Move motor 100 steps in negative direction
(LVO+MOVR 200) Move motor 200 steps in positive direction
Measured Color (MCG)
Select the Measured Color Gamut file. This file describes the native colorimetry for the projector as installed and is
required for accurate color processing in the cinema electronics. This control is per channel to allow for different
colorimetry for applications such as 3D.
SUBCODE DESCRIPTION OF USE
Replace xxx with the channel number. Valid range is 101 - 164.
Cxxx
Select measured color gamut for the current channel.
NONE
