3.2 Operating variant (C)ommand
The Operating variant (C)ommand is part of level 1 diagnostic mode.
The commands that can be given are the names or the numbers of the
Service Test Level (point 4). A command must be terminated with a
<return> character from the control PC. When typing commands, the
backspace key can be used to make corrections.
In case of typing errors in the command, an error message is returned.
Example:
DD>222↵
0001 Unknown command ER @
DD>
If the command is recognised, the command is executed. Result and
output of an activated (and terminated) command will be sent back to
the control PC according to the standard layout (point 3.3).
Example in case the DVD-Player is correct:
DD>22↵
0000 OK @
DD>
Example in case the DVD-Player is faulty:
DD>22↵
1601 Data line X is not connected to the DSM/DVP ER @
DD>
3.3 Service Test Results
Results returned from a Service Test Level to the control/service PC
will have a maximum length of 160 characters and are terminated by
a CR character (included in the string length)
The result has the following layout
<number> <string> [OK | ER] @ <CR>
<number> is a 4 digits decimal number padded with leading zeros if
value is less the 4 digits. The first two digits identify the generating
Service Test Level (or goup of Levels), the latter two digits indicate the
error number.
<string> is text string containing information about the result of the

Service Test Level.

<number> and <string> are defined in the output sections of each
Service Test Level. See description of Service Test Level in
point 4.
