[USB-1208-FS-Plus Bit 8 and 9 Both Go Low Together]

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.

 

[USB-1208-FS-Plus Bit 8 and 9 Both Go Low Together]

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

[A USB/PMD-1024HLS was not assigned to Board 0]

Thanks Jeffrey.  That takes care of it.

[A USB/PMD-1024HLS was not assigned to Board 0]

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?
