DM8000 User Manual
Take note of the following considerations:
•
RVC connects to one of the GPIO pins used for volume adjustment.
•
AUX connects to one of the GPIO pins used for selecting which channel’s
volume is active and available for adjustment.
NOTE
: Once the CP8000UL/CP8000EU RVC and AUX pins each connect
to a specific DM8000 GPIO pin (1 thru 6), those pins cannot be used for
other functions.
After connecting CP8000UL/CP8000EU devices to DM8000, the user can then
use the DM8000 DSP Designer software to launch dedicated CP8000 modules for
remote configuration and control.
CP8000 dialog Boxes
In the software, when the user chooses a new CP8000 module and drops
the module into the Build Window, the software will automatically launch a
Parameter Dialog Box so that users may select and designate specific GPIO pins
for AUX and RVC.
For example, the following screenshots show the CP8000 AUX pin being assigned
to Pin 4 of the DM8000 GPIO port, while the CP8000 RVC pin is assigned to Pin 6:
CP8000 Parameters Dialog Box for AUX Pin Assignment to GPIO
CP8000 Parameters Dialog Box for RVC Pin Assignment to GPIO
After selecting and assigning GPIO pins for AUX and RVC, double-click on the
CP8000 module to launch a Control Dialog Box to select which specific Input
Output Module (see “3.1 Input Output Modules”) will have its volume controlled
from the CP8000 series unit.
CP8000 Control Dialog Box for Selection of Input Output Module and CP8000 Controller Button
The left-hand Module pulldown menus contain a list of Input Output Modules
available for volume control.
CP8000 Control Dialog Box with Module Pulldown Menu
The right-hand Channel pulldown menus contain a list of CP8000UL/CP8000EU
panel buttons available for assignment. (Each CP8000 device has 6 buttons on
the front panel available for assignment.)
CP8000 Control Dialog Box with Channel Pulldown Menu
After completing the DM8000 system design in the DM8000 DSP Designer
software, compile and download to device.
The CP8000 device can now control the assigned volume parameter as
designated in the CP8000 module.
