CDi DriveCore Series Operation Manual

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 "Amplier

Information" on page 35

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 Global Settings panel in

Audio Architect. See "Amplier Information" on page 35 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 Global Settings panel in Audio Architect. See "Amplier Information" on page 35 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 Global Settings panel in Audio

Architect. See "Amplier Information" on page 35 for more information on conﬁguring this input port.

PIN 6 (GND): Provides the ground potential for GPIO outputs and the AUX port.
