Output Display

When you add an output channel to an Output display, DAQami creates an output control for users to change the output value when an acquisition is running. The type of control that is created depends on the type of output channel. An example is shown here:

Output display

Refer to the callout numbers below for a description of each component on the Output display.

CalloutNameDescription
1Output controlsAn output control is created for each output channel added to the display. The type of control depends on the type of output signal. The control color corresponds to the channel color. Right-click on the control icon to show a context menu with options to remove the channel or change its color. A signal type setting is also available for analog output channels that support hardware pacing. Refer to the Output Channel Controls discussion below.

Output Channel Controls

Typical controls for each type of output signal are shown here.

The name on the control is specific to the signal name on the selected hardware, and may differ from the controls shown here.

Output ChannelControlDescription
Analog OutputAOUT slider control
Slider control
Use the analog voltage slider control to change the analog output signal during an acquisition. The slider control is the default control created when you add an analog output channel to an Output display

Right-click on the control to show a menu with the following options:

  • Remove From Display: removes the channel and control from the Output display.
  • Color: opens a color palette to select a color for the channel.
  • Signal Type (hardware-paced AO support only): if the device supports hardware-paced analog output, select Waveform to convert to a waveform control. Use this control change waveform settings during an acquisition.

Note: Changing an analog output signal with a Slider control affects the frequency of the hardware-paced waveforms on all other AO channels. There is currently no known work-around for this issue.
AOUT waveform control
Waveform control
Use the analog waveform control to modify waveform settings before or during an acquisition.

If the selected device supports analog output scanning, select Signal Type»Waveform from the context menu to change from a slider to a waveform control.

To change back to a slider control, select Signal Type»Slider from the context menu.
Digital OutputDOUT switch control
Digital switch control
Use the digital switch control to change the high/low state of a digital pin during an acquisition.

Right-click on the control to show a menu with the following options:

  • Remove From Display: removes the channel and control from the Output display.
  • Color: select a color for the channel from the color palette.
  • Signal Type (hardware-paced AO support only): if the device supports digital output scanning, select Square Wave to change to a square wave control to configure the output channel settings.

DOUT wave controlDigital square wave control

If the selected device supports digital output scanning and all digital bits on the port are configured for output, select Signal Type»Square Wave from the context menu to change from a switch to a square wave control.

To change back to a switch control, select Signal Type»Switch from the context menu.
Counter/Timer OutputCOUT controlUse the pulse output control to configure the pulse settings before or during an acquisition.
