Set Digital Output at +5V in HDC2450

I want to set at +5V digital output 6 (DOUT6) mapped on main connector as pin8 by using Linux API.

I\'ve read the API documentation, but I still have problems.

I\'m trying to do this with:

but it doesn\'t work.

Can you help me, please?
I do not know in my code I have to use the index number (6) or the label name (DOUT6) or the mapped pin8 (8).

In addition, I know that digital output are open drain, so if I want to power on a device which works at 5V, do I have to connect it between digital output 6 and VCC?

Thank you a lot!

EDIT: I\'ve better read the manual and I know that I have to put my load between digital output and gnd.
Moreover, I think I have to use device.SetCommand(DSET, 6) if I want to set HIGH digital output number 6 on pin8. Is it correct?

I added an edit to my previous topic.

I solved the problem by using DSET to enable digital output! Everything is OK, now.
