Switch Polarity of cFP-AO-210

[blindjoe]

Hello, 

I am trying to control a Vickers proportional valve which requires a +- 10 V command signal using the cFP-AO-210 module which outputs 0-10 V. Is there a way I can switch the positive voltage to negative within labview?

Thank you

No, it is a limitiation of the hardware itself.

There are off-the-shelf converters, one example of such:
