DataPort Pinout

The illustration below shows the pin assignments used for the DataPort DE-15 (female 15-pin high-density D shell) connectors. For connector naming in this help file, refer to About Connectors.

This information is shown for reference only and is subject to change without notice as the DataPort feature is specific to QSC products and not intended for interface to other manufacturer’s equipment.

This view is of the female chassis connector on the DataPort card.

Pin	Signal Description	Description
1	Channel 1 Minus (-) Signal	Channel 1 Audio (-)
2	AC Standby Control	Places the amplifier in standby
3	V-MON Channel 1 Subcode 1 - Bridge Mode & Power Detect	Voltage on Channel 1 Detects bridge mode of the amplifier Detects amplifier power on
4	I-MON Channel 1 Subcode 2 - Temperature, Channel 1	Current on Channel 1 Typically amplifier temperature, but may vary depending on amplifier model.
5	Clipping Channel 1 Protect Channel 1	The Clipping indicator goes on immediately if channel 1 is clipping. The Protect indicator goes on if the amplifier is overheating or has an over-current condition. This condition essentially disconnects the outputs from the amplifier.
6	Hard Ground	Chassis ground
7	Channel 1 Plus (+) Signal	Channel 1 Audio (+)
8	Channel 2 Plus (+) Signal	Channel 2 Audio (+)
9	+15 V from Amplifier	Unused Input
10	Data Reference Ground	Reference for all monitor signals.
11	Channel 2 Minus (-) Signal	Channel 2 Audio (-)
12	Amplifier IDR (Model ID)	Each amplifier contains a resistor with a specific resistance that identifies the amplifier model The resistance is measured by the DPIO. The amplifier model is used to correctly interpret all other DPIO data and signals. If the amplifier identified in Q-SYS Designer is different from what is detected, an error is displayed. The model that is detected is used for calculations regardless of the model identified in Q-SYS Designer.
13	V-MON Channel 2 Subcode 3 - Standby Mode Detect	Voltage on Channel 2 When the amplifier is first powered up, it goes into standby mode prior to normal mode and is indicated on this pin. In addition, if the amplifier is placed in the standby mode it is indicated on this pin.
14	I-MON Channel 2 Subcode 4 - Temperature, Channel 2	Current on Channel 2 Typically amplifier temperature, but may vary depending on amplifier model.
15	Clipping Channel 2 Protect Channel 2	The Clipping indicator goes on immediately if channel 2 is clipping. The Protect indicator goes on if the amplifier is overheating or has an over-current condition. This condition essentially disconnects the outputs from the amplifier.

Signal Description

Description

Channel 1 Minus (-) Signal

Channel 1 Audio (-)

AC Standby Control

Places the amplifier in standby

V-MON Channel 1

Subcode 1 - Bridge Mode & Power Detect

Voltage on Channel 1

Detects bridge mode of the amplifier

Detects amplifier power on

I-MON Channel 1

Subcode 2 - Temperature, Channel 1

Current on Channel 1

Typically amplifier temperature, but may vary depending on amplifier model.

Clipping Channel 1

Protect Channel 1

The Clipping indicator goes on immediately if channel 1 is clipping.

The Protect indicator goes on if the amplifier is overheating or has an over-current condition. This condition essentially disconnects the outputs from the amplifier.

Hard Ground

Chassis ground

Channel 1 Plus (+) Signal

Channel 1 Audio (+)

Channel 2 Plus (+) Signal

Channel 2 Audio (+)

+15 V from Amplifier

Unused Input

Data Reference Ground

Reference for all monitor signals.

Channel 2 Minus (-) Signal

Channel 2 Audio (-)

Amplifier IDR (Model ID)

Each amplifier contains a resistor with a specific resistance that identifies the amplifier model The resistance is measured by the DPIO.

The amplifier model is used to correctly interpret all other DPIO data and signals.

If the amplifier identified in Q-SYS Designer is different from what is detected, an error is displayed. The model that is detected is used for calculations regardless of the model identified in Q-SYS Designer.

V-MON Channel 2

Subcode 3 - Standby Mode Detect

Voltage on Channel 2

When the amplifier is first powered up, it goes into standby mode prior to normal mode and is indicated on this pin. In addition, if the amplifier is placed in the standby mode it is indicated on this pin.

I-MON Channel 2

Subcode 4 - Temperature, Channel 2

Current on Channel 2

Typically amplifier temperature, but may vary depending on amplifier model.

Clipping Channel 2

Protect Channel 2

The Clipping indicator goes on immediately if channel 2 is clipping.

The Protect indicator goes on if the amplifier is overheating or has an over-current condition. This condition essentially disconnects the outputs from the amplifier.
