UpCon remote control
UpCon English Manual (2014-10-07) 61
GPI 2 – Processing Control section
GPI (or SDI metadata) can be used to remote-
control your UpCon’s audio processing feature.
When GPI (or SDI metadata) is used for remote
control, blue “LEDs” on the respective Engine
pages will highlight the affected signal process-
ing parameters.
Enable button
Use this button to enable GPI 2 input for Pro-
cessing Control.
A “GPI” button that controls the same function
can be found on the Remote – Master page in
the Processing section.
Note that SDI metadata can also control audio
processing with the SDI Metadata license loaded
on a UpCon with SDI input/output.
Function parameter
Use the Function parameter to define the param-
eters that should be remote-controlled.
Bypass Format
Format conversion (i.e., DMix and UpCon) can
be bypassed.
GPI can control if the format conversion should
be bypassed as follows:
Format conversion is bypassed when the GPI in-
put is min (0V)
Normal operation (as specified by the Engine
preset) when the GPI input is max (3V3) or not
connected.
On the respective Engine page (Main), the For-
mat Conv. parameter will be greyed out, and a
blue LED indicates that it is being remote con-
trolled.
Engine parameter
Settings: E1, E2, E1+E2
Use the Engine parameter to specify which En-
gines should be remote-controlled.
Status field
The status field is intended for diagnostics dur-
ing the setup of GPI control.
“Active” display
Displayed when the selected Function is active
due to the GPI signal being at min. (0 V) and dif-
ferent from default/unconnected (3V3).
“Idle” display
Displayed when the selected Function is inactive
due to the GPI signal being at max. (3V3) or un-
connected. The device’s behavior is defined by
the currently active Engine preset.
“(N/A)” display
Displayed when the algorithm currently loaded in
the Engine does not support the selected Func-
tion and therefore GPI is not controlling it. The
device’s behavior is defined by the currently ac-
tive Engine preset.
Details regarding GPI 2 signals
GPI 2 is receiving fixed-state, latching signals. A
validation process is performed when receiving
a new GPI voltage. The incoming voltage needs
to be at the new level for 40 ms before the pro-
cessing change is initiated. The processing oc-
curs nearly instantly.
For information on voltage windows and GPI cir-
cuits, see “Appendix 2: UpCon GPI/O page” on
page 101.
