ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com

The Conﬁguration File is used to specify such items as:

• The name and location of models loaded at start-up

• The default directory path where your sound ﬁles are located

• Network conﬁguration parameters (Host, DIS, and Terrain)

• Preampliﬁer gain settings (if Waveform Synthesizers are being used)

• System Frame Rate

For systems which are incorporating control devices attached to RIUs, a cell routing conﬁguration

ﬁle will also be required. This ﬁle contains routing information for data sent to and from RIUs,

audio models, and the state machine (DLL) located on the DACS.

This ﬁle will typically be delivered by ASTi as part of custom panel, and simulation development.

The default name for the cell routing conﬁguration ﬁle is default.pth, and it is typically located in

the C:\mbuilder\user\models\ directory.

Consult the Model Builder Reference Guide section for a complete description of the system con-

ﬁguration commands and features.

At start-up, Model Builder looks for default.cfg in the current directory. If the ﬁle is not found,

Model Builder runs but uses fail safe settings for each command line feature.

Model Builder also looks for default.pth in the c:\mbuilder\bin directory. If the ﬁle is not found,

no cell routing will take place. If the ﬁle is not present, and no cell routing is necessary, then there

will be no negative effects on system operation.

You can modify a conﬁguration ﬁle using the DOS text editor or any ASCII text editor you wish.

You may also use a different ﬁle name for the Conﬁguration File. To use a different Conﬁguration

File name, enter the ﬁle name after the MB command when you start Model Builder. The format

is shown below:

C:\MBUILDER\USER\MODELS --> MB <filename>

Note that all conﬁguration ﬁles require the .cfg extension. When specifying the Conﬁguration File

name with the MB command, however, you do not need to add the .cfg extension to the ﬁle name.

This feature is useful for creating different start-up conﬁgurations during testing. You can also add

the ﬁle name speciﬁcation to the MB command in your autoexec.bat ﬁle. Remember, you must

start Model Builder from the directory containing the Conﬁguration File for Model Builder to

read your Conﬁguration File parameters. Changes to your autoexec.bat ﬁle will only take effect

upon restart.

Additional Software

Support software installed on the DACS includes the DOS operating system and in some cases

additional support software such as tape backup. DOS provides the Model Processor with a stan-

dard PC DOS environment as well as extra utilities such as an editor for ﬁle modiﬁcation. Vendor

documentation for all installed packages are included with the DACS.
