USB-6212 5V lines

[sbk143]

Two questions:

1)

Does anyone know what are the 5V lines on USB-6212? Are they input or output or external power? Does it require external power or it's powered by USB?

2)

Can you use P0.x, P1.x and P2.x (total 32 lines) as digital outputs?

Hi sbk143,

Pages 33 and 85 of the User Manual explain the connector information.  Hopefully this helps!

Thanks.

On USB-6009 what does the below Note mean?

Note- While the device is in USB suspend, the output is disabled.

Does it mean the +2.5V and +5V reference power sources are not available while USB is connected? Is there a way I can use the sources and perform data aquisition on AI and also control AO lines?

[HeatherBaker]

USB suspend mode is a power save mode.  The note means that if the USB device goes into this power save mode then the reference outputs are disabled.  Analog input, analog output, digital input, and digital output are all types of tasks.  You can run multiple types of tasks at one time.  Please keep in mind the USB-6009 has one analog input timing engine and no hardware timing engine for the analog output or digital I/O.  You can contain multiple AI channels in the analog input task but they must all use the same timing configuration.  As the USB-6009 has no hardware timing engine, the device uses software timed generation.  See the attached image as an example of using AI and AO simultaneously.  I started with the Analog Output software time generation example.  Hopefully this helps!

*Please keep one question per thread
