SOFTWARE SUMMARY
The OPTIMOD-PC driver is responsible for low-level communication between the
OPTIMOD-PC card and your computer's operating system. When the driver starts up,
it checks a flag on each OPTIMOD-PC card to determine if it needs to reload DSP
code into the card.
It does not reload DSP code or parameters when Windows reboots nor-
mally, as it might after a security update, for example.
When the computer first powers up and Windows starts, the driver temporarily
loads a general-purpose preset that enables the card to pass audio. It also reloads
the system parameters, like input and output levels, which it reads from the com-
puter's Registry. As soon as the OPTIMOD-PC service finishes starting up, the service
will load the same processing preset that was active on the OPTIMOD-PC card when
the computer shut down. If the service does not start up for some reason, then this
power-down processing preset will not be restored and the general-purpose preset
(loaded by the driver) run instead.
The service is also responsible for verifying that the DSP code version running on the
card is the same as the DSP code with which the service was compiled. If it is not, the
service will load the more recent DSP code. Additionally, the service is an intermedi-
ary that allows the OPTIMOD-PC Control Application to talk to an OPTIMOD-PC
card, whether local or on the network.
OPTIMOD-PC will continue to pass audio through its hardware inputs and outputs
even if the Optimod-PC driver and service stop running.
