project.

replacement in advance.
1. In Database Generator, click Edit to enter the settings page for the
projector.
2. Add a command by clicking and double-click the command column to
type the command of requesting for the cumulative lamp usage (hour).
Consult the user manual for the device to find out the operation command.
3. Set up a variable to store the queried value.
a) In the Message column, click Edit . The Edit Messages window
appears.
b) Click the Script tab and click +Add Script and name the script.
