Wrong Voltage Level in a Digital Output with PMD-1208LS

[ChDaniel]

Hi everybody,

I am using a PMD-1208LS USB DAQ with LabVIEW 7 Express. I have been trying to output a digital data, but the Hi voltage level I got is 1.5 V, which is not enough to work with ttl devices.

By the other hand, I tried to do the same using MatLab 7 Release 14, and the Hi voltage level I got is 5.3 V, which is a logic Hi indeed. So, what´s wrong with my setup in LabVIEW?

Please help me. Thanks in advance.

Hello ChDaniel,

That must be a Measurement Computing device. Since it is not NI's, you need their driver to get it to work. If you still can't get it to work, please contact Measurement Computing for support.
