6040E DIO Port Issue

[lilocomotiv]

I have a PXI-6040E DIO port P0.0(Pin 52) is hooked upto a OPTO-22 G4ODC5(TTL Input) module. When I run DIO Port COnfig.vi with line direction map set to -1(All Inputs set to Digital Out) it turns ON all inputs(PO.0-7). When I actually turn ON the DO using DIO Port Write.vi, it turns OFF. Tried inverting the line in MAX. Didnt work wither. Any inputs?

When you initiallize an E series device this is normal.  Not surprisingly NI offers newer reconfigurable DAQs that are DAQmx compatable and does not recommend the E series for new applications. 

I recommend investing in modern hardware

Hello lilocomotiv,

The behavior you are describing is the default behavior of E Series devices. For setting the states of the digital lines see KnowledgeBase 266KK6YF: Setting the Default State of the Digital Lines on E Series DAQ Boards.
