Extron electronic IN1508 manual Using the Command/Response Table, Symbol definitions

Using the Command/Response Table

The command/response table begins on the next page. Except for the gain and attenuation settings, upper or lower case letters are acceptable in the command field. Command and response examples are shown throughout the table.

The table below shows the hexadecimal equivalent of each ASCII command.
