3. Command Descriptions
3.1 Lens Shift, ZOOM and FOCUS Commands
The following commands turn on the specified motors. The motor will stay energized until an <ESC> character is sent to
the projector. The last character of each command is an ASCII digit form 0 to 3 with no intervening whitespace. This
determines motor speed with 0 being the slowest and 3 the fastest.
If an N prefix is appended to the command mnemonic the command is a NUDGE. NUDGE commands turn on the
specified motors at full speed for a timed period. An <ESC> character is not needed to terminate the command. The
purpose is to generate small changes in image position, focus or size. The last numeric character of the command
determines period the motor is energized with 0 being the shortest and 3 the longest. Due to backlash in the motor/drive
assemblies, a single NUDGE – especially a 0 or 1 – may not generate any noticeable change.
All of the motors have clutches or limit switches to prevent damage if they are allowed to run after reaching a mechanical
limit.
