During both Local and Host DRED tests, each Waveform Synthesizer output generates a different
type of sound. Table 1 describes the type of sound heard on each Waveform Synthesizer output
channel. If the Waveform Synthesizer has only two output channels, the first two sounds listed in
the table will be generated.
In addition, each input channel is connected directly to its corresponding output channel to facili-
tate communications testing.
If multiple cards are installed in the system, each card will replicate the above sounds.
Running Local DRED: Before running the Local DRED test you will need to have amplifiers
and headsets or speakers connected to your Waveform Synthesizers in order to hear the test
sounds.
To run the Local DRED test, quit from Model Builder. At the DOS prompt, make sure you are in
the “c:\mbuilder\user\models” directory and:
Type: dred_loc
Press: [return]
The Model Builder environment will boot up and load the DRED audio models. Sounds should
emanate from each output channel after the system has booted.
Running RIU DRED (For Host Interface): *** Need this information ***
Running Host DRED (For Host Interface): Before running the Host DRED test you may first
need to change the ethernet addresses and input data format type listed in the dredhos.cfg file
located in the C:\MBUILDER\DEMO\MODELS directory. Use the DOS editor provided with
your operating software to edit the file. Editor commands and descriptions are provided in the
DOS vendor documentation supplied with your system. Consult your Model Builder User’s Guide
or Model Builder Reference Guide for information on the configuration file and configuration file
command lines.
