Each mixer component supports a mono volume control and a mono mute control.
Windows mixer controls can support more than one channel. However, in this case,
these controls only allow one channel to be set. The same setting is applied equally
to both the left and right channels.
For audio source selection and muting, the Input Destination controls are commonly
used. In effect, the Output Destination controls will control all of the inputs at once.
Therefore, if individual input source switching, muting, or level setting is required,
use the Input Destination controls.
Other sound cards, especially consumer and some prosumer cards, do not offer au-
dio mixer or signal processing functions. Therefore, because the audio path runs
straight through the card, the input and output controls are essentially in series and
audio can be controlled at either the input or output. On the other hand, using an
audio card with integrated mixing and audio signal processing, such as OPTIMOD-
PC, requires the audio control to be at the inputs.

Administering the 1101 through Serial Ports

Using a terminal program like HyperTerminal, or an ASCII programmable GPIO de-
vice, you can control an 1101 card through a serial port of the computer that hosts
the 1101 you wish to access. When you are connected, you can retrieve information
and change settings on the 1101 by using simple ASCII commands, as discussed in
OPTIMOD-PC System/Mixer Control API starting on page 6-1.
•
Valid commands are in either upper or lower case, not a combination.
•
Only one valid command is permitted per line.
•
The 1101 will not respond to unrecognized commands.
