computer, see the user documentation that comes with it.

■ Using Control Commands

This section explains the commands that are used to control the projector from a computer.

Important!

z The commands that will be available to you depend on your projector model. Refer to your projector’s User’s Guide

for information about the menu items and button functions supported by your projector.

Example: Some models do not support “Lamp Time Reset”.

Command Send Format

• See the “Command List” for details about command names and settings.

• All commands use ASCII characters and decimal format integers.

• The projector will return a question mark (?) when it is sent a command it cannot recognize.

• Generally, the projector will ignore anything that is not a valid setting. However, in the case of a setting like VOL (volume) that

has a range (defined by minimum and maximum values), sending a value that is outside the specified range will change the

setting to its maximum value.

• If the projector is performing a process initiated by a previously sent command, a projector key operation, or a remote

controller key operation, send of the next command must wait until the projector completes the previous process.
