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:
Code Description
E10 Invalid command
E11 Invalid preset
E12 Invalid port number
E13 Invalid parameter (number is out of range)
E14 Not valid for this configuration
E17 System timed out
E22 Busy
E25 Device is not present
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.
Command/Response Table for Basic SIS Commands
Symbol definitions
] = CR/LF (carriage return/line feed) (hex 0D 0A)
} = Carriage return (no line feed, hex 0D)
• = Space character
| = Pipe (vertical bar) character
E = Escape key (hex 1B)
= = Future capability (not currently available)
X!
= Version number Listed to two decimal places (for example, x.xx)
X@
= Version and Build number The least significant bits is the build number (for example, x.xx.xxxx)
X#
= Verbose/Response mode 0 = clear or none
1 = verbose mode (not tagged, not broadcast)
2 = tagged responses for queries (tagged, not broadcast)
3 = verbose mode + tagged responses for queries (tagged and broadcast)
Default = 1 for RS-232 host control
NOTE: If ‘tagged responses’ is enabled, all read commands will return the
constant string + the data, like setting the value does, for example,
command:
ECN}
response: Ipn•X1@]
X$ = Baud rate 0 = 9600
1 = 19200
2 = 38400 (default)
3 = 15200
