Using the GPIO Control Port
Using the GPIO Control Port
CDi DriveCore amplifiers come with a 2-in, 2-out General Purpose In/Out (GPIO) control port in the form of a block connector. The Control port has
multiple uses which include fault status reporting, device preset selection, output muting, and more. Control ports are configured using the Audio Architect
software.

PIN 1 (Output 1): 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V. This pin is used for fault reporting. If a fault occurs in the
amplifier, this pin will change from a low/false state to a high/true state. Polarity can be inverted when reversed functionality is required. See
"Amplifier
Information" on page 32
for information on inverting this output.
PIN 2 (Output 2): 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V. This pin is used by Audio Architect and compatible HiQnet wall
controllers for generic output control functions. The functionality of this output is tied to the Manual Aux Output button in the Amp Info panel in Audio
Architect. See
"Amplifier Information" on page 32
for more information on the Manual Aux Output button.
PIN 3 (Input 1): 0VDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance > 20KΩ. This pin is used to trigger input
mutes. By default, a high/true state at the input will trigger the mutes. Polarity can be inverted when reversed functionality is required. Which input channels
are muted can be programmed from the Amp Info panel in Audio Architect. See
"Amplifier Information" on page 32
for more information on
configuring this input.
PIN 4 (3�3V): +3.3VDC output. LIMIT = 30mA. Output impedance = 100Ω to +3.3V. This pin provides the power source to drive the GPIO inputs. For
example, a simple switch between this pin and pin 3 (Input 1) will mute/un-mute the designated input channels (a closed switch connects the 3.3V for
high/true condition, an open switch allows the pin to float low for false condition).
PIN 5 (Input 2): 0VDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance > 20KΩ. This pin is used to trigger
preset changes between two stored presets depending on high/low state. Which presets are triggered can be configured from the Amp Info panel in Audio
Architect. See
"Amplifier Information" on page 32
for more information on configuring this input port.
PIN 6 (GND): Provides the ground potential for GPIO outputs and the AUX port.
