Serial interface settings
The serial interface of the projector acts as a Data Communications Equipment (DCE) device and its
settings can’t be configured. You must configure your computer’s serial communication program
(such as Microsoft® HyperTerminal) or your room control system’s serial communication settings
with the following values:
