Using the command/response tables
The command/response tables on the next page list valid command ASCII codes, the switcher’s responses to the host, and a description of the command’s function or the results of executing the command. Except when setting audio gain/attenuation, upper and lower case characters may be used interchangeably in the command field.

The ASCII to HEX conversion table at left is for use with the command/response tables.
ASCII to Hex conversion table
The command/response tables use symbols (defined below) to represent variables.
