Error Responses

When the DMP 44 LC is unable to execute the command, it returns an error response to
the host. The error response codes and their descriptions are as follows:

Command/Response Table Overview

Although the DMP 44 LC uses the same structure for SIS commands, there are two
variations. One is the global command structure documented in the

"Command/Response Table for Basic SIS Commands"

The second set of tables for DSP SIS commands uses the command structure outline
beginning with
same structure of basic SIS commands, they differ in how the software addresses the
individual processor blocks within the DMP 44 LC.
