Error Responses
When the unit receives a valid SIS command, it executes the command and sends a response
to the host device. If the unit is unable to execute the command because the command is
invalid or it contains invalid parameters, the unit returns an error response to the host. The
error response codes are:
E10 – Invalid command
E11 – Invalid preset number
E13 – Invalid parameter
E14 – Invalid command for this configuration
Using the Command and Response Table
The command and response table begins on the next page. Either uppercase or lowercase
letters are acceptable in the command field except where indicated for the audio level (gain
and attenuation) commands. Symbols are used throughout the table to represent variables in
the command and response fields. Command and response examples are shown throughout
the table. The ASCII to Hex conversion table below is for use with the command and
response table.
