I commented out the DBitOut() line. No the bits stay in the state that they were when the program last shut down. The problem is that, if Bit 8 and 9 are high when I shut the app down, they are still high when I start the program up the next time. When this line executes: ulstat = Daqboard.DBitOut(MccDaq.DigitalPortType.FirstPortA, 8, MccDaq.DigitalLogicState.Low) They both go low. I can't have that. It causes a crash situation. Actually if all bits are high, they all go low when the line setting 8 low executes. I will check to see if this is the case with all of the boards that I have.

This is the code in my FormLoad Event: 'Configure the Ports to output. ulstat = Daqboard.DConfigPort(MccDaq.DigitalPortType.FirstPortA, MccDaq.DigitalPortDirection.DigitalOut) If ulstat.Value <> 0 Then MessageBox.Show(ulstat.Message, "Universal Library Error ", MessageBoxButtons.OK, MessageBoxIcon.Error) Me.Close() End If ulstat = Daqboard.DConfigPort(MccDaq.DigitalPortType.FirstPortB, MccDaq.DigitalPortDirection.DigitalOut) If ulstat.Value <> 0 Then MessageBox.Show(ulstat.Message, "Universal Library Error ", MessageBoxButtons.OK, MessageBoxIcon.Error) Me.Close() End If ulstat = Daqboard.DBitOut(MccDaq.DigitalPortType.FirstPortA, 8, MccDaq.DigitalLogicState.Low) If ulstat.Value <> 0 Then MessageBox.Show(ulstat.Message, "Universal Library Error ", MessageBoxButtons.OK, MessageBoxIcon.Error) Me.Close() End If Bit 8 is set to low. Bit 9 goes low as well. What is causing this

Thanks Jeffrey. That takes care of it.

I get this error message when trying to run the sample code for this device. The board number assigned in instacal is 0. If I change it to 1, I have the same problem: Here is the offending code snippet: BoardNum = 0 DaqBoard = New MccDaq.MccBoard(BoardNum) '<======this is the default board number 'change it to what InstaCal has assigned for your USB/PMD-1024HLS ULStat = DaqBoard.BoardConfig.GetBoardType(typeVal) ' Get the typeVal property from the MccBoard object If typeVal <> 0 Then If typeVal <> 127 Then 'Code for USB/PMD-1024HLS is 127 MyMessage = "A USB/PMD-1024HLS was not assigned to Board " & BoardNum & " in InstaCal." & VB.vbLf _ & "Please run InstaCal to verify the board number and/or " & VB.vbLf _ & "change BoardNum = " & BoardNum & " in the frmDataDisplay_Load event" & VB.vbLf _ & " to the correct board number. Then re-run this program." r = MsgBox(MyMessage, vbExclamation, "USB/PMD-1024HLS not detected.") End End If End If The board tests fine in instacal. typeVal returns 118. If that means anything. What's wrong?
