Some parameters, such as the advanced input active area and blanking

parameters, are input mode dependent. Before recalling a user memory that

has not been previously saved, Extron suggests that you reset that memory so

that it is programmed for the current input mode.

Baud Rate screen

The Baud Rate screen displays the currently selected RS-232 port baud rate and

provides the ability to select a different rate.

To select a different baud rate, use the Menu or button to highlight the desired

rate and press the Enter (and save) button.

Delimiters screen

The Delimiters screen displays the currently selected RS-232 delimiters and

provides the ability to select a different set of delimiters. Delimiters are the leading

and end codes that identify the beginning and end of an RS-232 command code.

Extron products that use this command set can be set to recognize one of six

different delimiters: parenthesis ( ), brackets [ ], braces { }, slashes \ / less-than and

greater-than symbols < >, and the ! and # signs. If desired, several Extron products

that use this set can be connected together on one RS-232 serial control line, with

each device set for a different delimiter pair. Each unit only responds to codes sent

with the appropriate deliminators and ignores all other codes.

To select a deliminator set, use the Menu or button to highlight the desired set

and press the Enter (and save) button.

Reset RS-232 screen

The Reset RS-232 screen provides the ability to reset all of the RS-232 settings, such

as the baud rate and delimiters, to the factory defaults.
