Data Acquisition Toolbox Digital Input Read Error

Hi everyone,

I have used Data Acquisition Toolbox with a PCI-DAC 6703 from Measurement Computing for a while and did not have problems with it. However, recently I am struggling when using Digital Input block: it always reads '1' on all digital channels, regardless of the value I actually send (since it is a digital input, it never reads '0' when I send this value to any digital channel). I have tried installing and reinstalling the data acquisition device drivers, remaking all connections, but nothing worked so far. The other blocks from Data Acquisition Toolbox work fine, only Digital Input has this problem. Does anyone have any idea what could be causing this problem and what should I do?

Thanks in advance, Alceu Farias
