How to gather data via RS 232 and import it to Excel using VBA

[krazyjoe]

I have a Fluke 45 series multimeter. I would like to gather data from it through MS Excel and VBA. I have no trouble sending commands to the multimeter but I cannot figure out how to read data from the output buffer. I am going to go learn about MSCOMM32.OCX and see if it will be helpful. Any other suggestions would be great. Thanks in advance.

hi
an example of how to save incoming data from rs232
you may have to change settings and/or options because i don't know the specific format in which your device is sending data.

Private Sub Form_Load()
' chose correct settings for your device
Settings = "9600,n,8,1"
MSComm1.Settings = Settings
MSComm1.Commport = 1

With MSComm1
' receive chr by chr
    .InputLen = 1
    .RThreshold = 0
    .SThreshold = 0
    .InBufferSize = 10240       '10kb
    .InputMode = comInputModeText
    .Handshaking = 0            'None
End With
End Sub

Private Sub Receive()
FileName = App.Path & "\RS232.dat"
Open FileName For Output As #1
    Do
    DoEvents
    RxTxt = MSComm1.Input
' start capture if you get some input
' you may also wait for some other specific character
    Loop Until RxTxt > vbNullString
    inbuff = vbNullString
   
    Do
    DoEvents
    RxTxt = MSComm1.Input
' data is supposed to be separated by Chr(10)
' chose another separationmark if neccesary
        If RxTxt = Chr(10) And Len(inbuff) > 0 Then
            If Left(inbuff, 1) = Chr(10) Then inbuff = Right(inbuff, Len(inbuff) - 1)
            Print #1, inbuff
            inbuff = vbNullString
        Else
            If Len(RxTxt) > 0 Then
            inbuff = inbuff + RxTxt
            End If
        End If
' data is supposed to end with Chr(3)
' chose another endmark if neccesary
    Loop Until RxTxt = Chr(3)
Close
End Sub

Dear Sir,

Your codes save mscomm data to the following file.
FileName = App.Path & "\RS232.dat "

But I want to show the data into listbox

Please help
