LEDs
The DAQPad-6016 OEM has two LEDs that reflect the state of the device.
The green READY LED indicates whether the device is powered on and
configured as a USB device. The yellow ACTIVE LED indicates whether
there is activity over the USB bus. Figure 3 shows the pins that connect the
LEDs to the device.
Figure 3. DAQPad-6016 OEM LEDs (111 mm ×163 mm Version)
The READY LED has two sets of pins. The first set of pins labeled 1a and
the resistor labeled R5 are used to connect to the onboard LED. The 220 Ω
R5 resistor drives enough current to power on the LED.
The second set of pins labeled 1b allow you to connect an external LED
circuit to the device. You can solder wires to these pins.
The set of pins labeled 2 and the 220 Ωresistor labeled R6 are used for the
ACTIVE LED. The ACTIVE LED does not have a separate set of pins to
connect to an external LED circuit.

Pin 1 is connected to VDC through the fuse (reference designator XF1).
The VDC is the voltage provided by the power supply through the power
connector (reference designator J10) and must be 9–25 V.
Pin 2 provides power to the circuitry on the DAQPad-6016 OEM. When
the switch is in the On position, the VDC power supply from pin 1 is routed
to pin 2.
Pin 3 connects pin 2 to ground when the switch is in the Off position.
This allows the charge on the DAQPad-6016 OEM to leak to ground when
it is powered off.
Figure 5 shows a schematic of the switch.

NRSE/RSE Switch (111 mm ×163 mm Version)
The DAQPad-6016 OEM device can make differential or single-ended
analog input measurements.
In nonreferenced single-ended (NRSE) mode, the ground reference signal
is provided by the user on the AI SENSE pin. In referenced single-ended
(RSE) mode, the ground reference signal is AI GND, the ground of the
DAQPad-6016 OEM device.

Chassis Ground
Chassis ground provides a connection between the enclosure and USB
ground.
D GND is connected to the chassis ground at the bottom edge of the board
through two 0 Ωresistors. The chassis ground directly connects to USB
ground, which connects to earth ground. Figure 6 shows where the different
grounds are connected.

2To make RSE measurements, you must set the Analog Input Terminal Configuration property of your AI Task to NRSE in
NI-DAQmx. Even though RSE mode is not exposed in the software, setting S1 to RSE and setting the Analog Input Terminal
Configuration property of your AI Task to NRSE will allow you to make RSE measurements.
