What is the DIO parameter VI

[Benoit M.]

I have a Problem.

I want to use PCLK like an output when I send a message in output.

For that, I must change the direction of the PCLK.

I have readden that I must set "Clock reverse mode" attribute to ON in the DIO parameter VI.

My problem is that I don't know what is the DIO parameter and I have not found this VI.

Could you explain me what I must doing.

Thanks

Hi,

First of all, it would be great if you could give us some information about the hardware you are using.
I suspect it's a 6533 also called DIO-32HS

If this is the case the links below will provide you with some information.
To answer your question: The DIO parameter vi is part of the Traditional NI-DAQ driver and can be found under
Measurement I/O -> Traditional NI-DAQ -> Digital I/O -> Advanced Digital I/O

If you can't find the vi there, you have probably not installed the Traditional NI-DAQ driver.
(you can find it here: http://joule.ni.com/nidu/cds/fn/p/sn/n23:3478.36.5303.927/lang/en )

The 6533 can be used with both Traditional NI-DAQ and NI-DAQmx but not with the 2 at the same time.
So using vi's from NI-DAQmx and Traditional DAQ in your VI won't work.

If you are thinking of using NI-DAQmx as driver then you could use the Timing block and set it on Handshaking -> Burst (Export Clock)
Also you can look at example of NI-DAQmx using the example finder and limiting the search for your hardware on the bottom left.
Then under Hardware input and output -> DAQmx -> Digital handshaking you can find examples.
