There is a 9V signal active on Pin9 when the control panel power is turned on in the on-screen
display (OSD) menu and should never be wired to use anything other than SMART approved
control panels.
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
Baud rate 19200
Data length 8
Parity bit None
Stop bit 1
N O T E S
l Asynchronous mode is disabled by default in the projector.
l Remote echo is not enabled on the serial connection.
l All commands should be in ASCII format. Terminate all commands with a carriage return.
l All responses from the projector are terminated with a command prompt. Wait until you receive
the command prompt indicating that the system is ready for another command before you
proceed.
l The room control feature of the projector is always on.
To configure your computer’s serial interface
1. Turn on your computer, and then start your serial communications program or terminal emulation
program.
2. Connect your computer to the serial connection cable you previously connected to the
interactive projector.
