N O T E
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 SMART UF55 projectors.
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:
Setting
Value
Data Rate
19.2 kbps
Data Bits

To configure your computer’s serial interface
1. Turn on your computer and then start your serial communications program or terminal
emulation program.

control panel.
