Configuration File Structure
MTM400 MPEG Transport Stream Monitor Technical Reference
This appendix provides an overview of the MTM400 configuration file, which
allows units to be completely configured or partially updated. If no configuration
file is implemented, settings will use default values. Note that configuration files
can be uploaded to the unit, but must be made active to have any effect.
The file is presented in XML (Extensible Markup Language) format. XML is a
hierarchical language that can be interpreted by MTM400 units. It can be edited
using either a simple text editor such as Microsoft NotePad, or a more sophisti-
cated editor.
An XML configuration definition file (*.xsd) can be downloaded from the
MTM400 by entering the following address in your browser address field:
http://<mtm400 address>/config.xsd
An XSD file, used in conjunction with an XML editor, will ensure that any
proposed XML configuration file is valid. Examining the XSD file will reveal
the complete range of available elements and attributes.
XML is formatted using elements and attributes, which are indicated in a
document using tags. Tags begin with a '<' and close with a '>'. End tags
include a '/' before the name of the element; empty tags include a '/' before the
closing '>'.
<LBandSettings Name = "Default">
<OscillatorFrequency>10600000</OscillatorFrequency>
<TransponderFrequency>11837000</TransponderFrequency>
<PolarVolts>0</PolarVolts>
<SymbolRate>27500000</SymbolRate>
<ViterbiRate>2</ViterbiRate>
<ViterbiRateAuto>1</ViterbiRateAuto>
<Tone22K>0</Tone22K>
<InvertSpectrum>1</InvertSpectrum>
</LBandSettings>
The <LBandSettings Name = "Default"> tag opens the LBandSettings element.
The LBandSettings attribute, Name, is set to 'Default'. The LBandSettings
element contains a number of discrete elements. This results in a nested
structure. Any of the elements can contain further nested elements. The
LBandSettings element is closed with the closing tag </LBandSettings>.
