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

[pmtwiss]

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.

Thanks for the help,

-Peter

According to http://forums.ni.com/t5/LabVIEW/8451-SPI-Error-with-ADXL346/m-p/2163388/highlight/true#M697059 you don't have variable voltage levels.

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?
