Note Refer to the
Manual to change the settings that determine the behavior of your DAQPad device
during the suspend state.
© National Instruments Corporation
When the DAQPad exits the suspend mode, NI-DAQ will reinitialize your
DAQPad device and all I/O signals to their default state, regardless of
whether your DAQPad device is in low power mode or static mode. This
action might change the current I/O states and gain if your DAQPad device
is the low powered, static mode.
The default behavior of your DAQPad device is to go into powered,
static state when the computer enters its suspend mode.
In the powered static state of your DAQPad device, you can draw current
from the +5 V pin on the connector and all digital I/O lines and analog
output channels will be static at a fixed voltage.
Set_DAQ_Device_Info
If low-power consumption is a concern, the recommended way to turn off
your DAQPad device is with the rocker switch located on the rear panel.
This switch turns your DAQPad device on and off by disconnecting both
the external power supply and the USB supply.
It is also possible to turn off your DAQPad device by detaching the
USB cable while leaving the external supply attached; however, several
milliamperes are continually drawn from the external supply in this case,
although no power is drawn from the USB supply. If you are using a battery
pack, such as the BP-1, it is best to use the rocker switch on the back panel
to prolong the charge of the battery.
