system manual Part I : installation & operation 6.2
6.1.2 Documentation
Both remote access methods are supported by LabView libraries. During the Dazzler program
installation, the libraries are bundled with the Examples, hence make sure this feature is in-
stalled. There are two help files (LabView like) DzNetRem_Help.chm for the socket based library
and DzTxtRem_Help.chm for the ”text file mode”. They document completely the functions
(Vi’s) available, and the example utility programs provide the necessary documentation to get
further.
For other languages than LabView, documentation support is limited. Examples coded in
Python and using DOS batch script may be obtained on request. They only document the
”text file” protocol.
The path to these examples is given by the icon ”Vxyz-Examples”, most often:
C:\Program Files\Dazzler\V550d - Examples\Source Code
Note that the socket based IPC uses some of the formats developed for the text file IPC, thus
reading once all the sections is advised since an attempt to avoid duplication was made.
6.2 Basic text remote control
This mode of operation is activated by setting/toggling the remote enable menu option in the
Setup menu (the unit accepts remote commands but can still be operated manually). The
”remote enabled indicator” lights up on the front panel. When the main Dazzler program is
running in this mode, it periodically checks for the existence of a text file named request.txt
in the default directory (see subsection 5.3.1). The active indicator blinks for a short time
whenever such a file is found. In the simpler case, the file contains a single line of text describing
an absolute path to a wave text file, see Figure 6.1.
The file associated with this path is read. The front panel controls are modified according to
its content. The new time signal is computed and is transferred to the Dazzler RF Generator.
The effect is thus identical to a manual change of the controls, followed by a single push on the
load button. When the controls have been set and associated actions have been performed the
file request.txt is deleted. The remote ”requestor” program can thus wait for the request file
to disappear to determine that the remote actions have terminated, and proceed with the next
operations.
6.2.1 Requests
Requests are text files named request.txt put in the default directory (see subsection 5.3.1).
This name is hard coded and cannot be changed.
In the request.txt file, the first line is generally a wave file path, which format follows sec-
tion 5.4. The parameters in the wave file describe shaping changes to be applied on GUI
