Serial Interface Settings

You must configure your computer’s serial communication program or your room control system’s serial
communication settings with the following values:

NOTE: Commands must be typed in ASCII format. Terminate all commands and responses

with a carriage return.

1.

Connect your computer to the Unifi 45 projector’s serial connector using a straight through

DB9M-to-DB9F cable.

2.

On your computer, start your serial communications or terminal emulation program.

3.

Configure your serial communication parameters by following your program’s instructions.

4.

Configure your serial interface settings using the table in the previous section, and then press ENTER.

An Invalid command, ? for help message appears and the “>” character appears as a command prompt

on the next line.

5.

Type commands to configure your settings.

NOTES

If no message appears or an error message appears, your serial interface configuration isn’t correct.

Return to step 3, and then reset your serial interface settings.

To see a list of available commands, type ?, and then press ENTER.

When using your terminal emulation program, activate your program’s local echo setting if you want

to see characters as you type them.
