Port directions on DaqPad-6508

[tman]

The user manual for the DaqPad-6508 specifies that each of the ports APA-APC,BPA-BPC,CPA-CPC,DPA-DPC can be configured as input or output.  From my experiance programming this device with labview it appears that I am only able to specify the direction at the PPI level.  For example, I tried to configure APA as input and then APB as output, but when configuring APB for output, APA also gets switched to output.  Can each individual 8 bit port within a particular PPI be configured as input or output independently without affecting the other ports within that PPI?  If so how do I do that because I have not been able to do that to this point.

Thanks

Hello,

You are correct that you cannot specify 1 port to be input and another output in the same PPI. Take a look at this KnowledgeBase, it explains why this is the case and links to the block diagram for this device:

Hope this helps!
