request information such as projector lamp use, current settings and network addresses.

The following table provides the pin configuration on the SMART UF75 projector. This pin
configuration follows a three-wire connection so that astraight-through male-to-female RS-232 serial
cable connects to the projector’s serial interface in the following arrangement:

On projectors with the RS-232 connector labeled Control 9v (rather than Control), pin 1functions
as a +9V DC power source only for use with older model ECPs such as the ones shipped with
SMARTUF55 projectors.

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:
