How to use Programmable resistance 2720

[momo2013]

Hello,

I am using and programming with PXI-2720. Could I set the resistance value in CVI program?

I put the niswitch.fp in my project.  

Do I need to control all relays for making 30ohm( example value) at my program?

Could you help me if you have any sample codes or references?

I have used "272x Reference VIs" for LabView.

I am looking for similar instrument driver for CVI.

Thank you,

Insuk

Maybe I need to use the following function:

niSwitch_InitWithTopology (, NISWITCH_TOPOLOGY_2720_INDEPENDENT, VI_FALSE, VI_TRUE, );

Thank you,

Insuk

I think I get the way how to calculate.

Thank you!

Hey Momo,

Certainly let me know if you have any questions.  To answers your initial question, yes, you'll need to manually configure each relay if you're not using LabVIEW, as the native driver works at the relay level.
