NI-USB-8451 1.8V logic not working - Error

Hello,

 

I have an NI-USB-8451. Using LV13

 

I cannot set up the device using1.8V logic. I get an error on the first argument, which is the logic level. Work fine for 3.3V.

 

My pullup enable also fails, but I gave up on that a long time ago.

 

I have verified that this device support multiple logic levels in the reference manual. 

 

Why cannot I not configure this device for 1.8V logic and pullups? This is rediculous..

 

I am using 2.1.2f version of the drivers, and I can see it in automation and explorer.

 

I can use this day in and day out in 3.,3V logic, just can't set it up for 1.8V logic, or 2.5..so any of the non-defaults, it fails.

 

*** SEE ATTACHED 2 PICTURES.

 

Thanks for the help,

-Peter

Yeah I see it now. Interesting I have to dig through multiple documents, their SW doc even shows to use the voltage I/O parameter to 'set' the I/O level. i

 

Well they better take it back, this is BS. I even talked to their direct sales people and made the purcahse through them. I specifically asked them what was the difference? Their reply? "It's the new version, same thing" How do they sell this stuff if they don't even know WTF they are doing?
