andyf Posted February 25, 2014 Share Posted February 25, 2014 It is my understanding that the ACC65E is limited to be 24 inputs and 24 outputs. However, it seems the control and setup registers can still be manipulated through GateIO. Please advise on the following: 1) Will changing the control register direction bits (bits 0..5) to anything other than 7 have a harmful impact? 2) Does the polarity control setup have any impact on how the card operates? 3) Does the card still support latching inputs through the setup register config?

steve.milici Posted February 26, 2014 Share Posted February 26, 2014 The direction sense of the ACC65E is fixed so you should keep the value at 7 to prevent an accidental write to an input. The inversion control can be used as needed as well as latching the inputs if needed. Link to comment Share on other sites More sharing options...
