Initial DAQPad-6020E outputs

I've got an application which needs to have a DAQPad-6020E's digital outputs start with a low output. What is happening is that as the program is started and the program enters the digital port configure vi, the Digital I/O pins appear to get set as inputs, which cause them to go to approx 1.3V. While this is not a legitimate logic "High" it is sufficient to turn on some of the controlled circuits. This lasts approximately 4 - 5 secs until it exits the vi at which point the outputs go low and the board starts functioning. If in the development mode (vs running an executable) this won't reoccur unless LabVIEW is exited and reentered. This occurs at the point in the "DIO port config.vi" where it makes a call to the lvdaq.dll, so I'm at a loss,
short of building some hardware solution.

By default, the power-up states of the digital lines on E Series devices is a high-impedance input state. Below is a knowledge base that discusses how to pull these lines low initially using some pull down resistors. I hope this helps.
