Model AD-340

3.2.2 Operation
For most installations, the AD-340 can be configured fully from the Front Panel
Push Buttons.
If needed, the GUI software has full access to all the capabilities of the Audio
Delay system that are not available from the device front panel controls.
The table below summarizes the control differences between the device controls
and the software.
The AD-340 Audio Delay automatically configures as a HID (Human Interface
Device) and does not require any USB drivers installed by the end-user.
When the AD-340 is attached to a valid USB port, the Windows™ system will
automatically detect and identify the appropriate USB driver. There may be a
short delay while this process occurs.
This detection and driver installation only occurs when the AD-340 is connected
for the first time. Afterwards, any time a previously connected AD-340 is again
connected to the PC; it will be silently configured by the system.
Notes:
•
The software scans the AD-340 settings at a rate of 10 times per
second to provide quick response times to the user.
•
The GUI software on-screen fields are disabled until a valid AD-340
device is attached to the system.
•
Only one instance of the program can run at a time.
Attempting to execute the application more than once
will result in an error message.
