On projectors with the RS-232 connector labeled Control 9v (rather than Control), pin 1 functions
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) oryour room control system’s serial communication settings with
the following values:
Setting Value
Data Rate 19.2 kbps
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
