Setting voltage level Digital Out in NI 6221

[Saridar]

Hi all,

I am working with a NI 6221. I am wondering if it is possible to change voltage level of digital out channels? Currenty I am using "Digital Bool 1line 1 point" as my DAQmx write.

Thanks,

Saridar

No, the outputs are ttl only levels.

...therefore you must use an external circuitry to change the level.

can be done with a ttl to cmos level shifter
