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” section that follows.
The second set of tables for DSP SIS commands uses the command structure outline
beginning with Command/Response Tables for DSP SIS Commands. While using the
same structure of basic SIS commands, they differ in how the software addresses the
individual processor blocks within the DMP 44 LC.
