OverRun

Applies to:

DATAQSDK Active X Control

Description:

Fires when the incoming data overwrites data that has not been removed from the buffer yet. Solutions could be to lower the sample rate, remove the data more quickly, or get a faster PC.

Example:

Private Sub DataqSdk1_ NewData(ByVal Count As Integer)

DQChart1. Chart (DataqSdk1. GetData)

End Sub

Private Sub Start_Click()

DataqSdk1. ADChannelCount = 8

DataqSdk1. SampleRate = 25000

DataqSdk1. EventPoint = 20

DataqSdk1. Start

Label2.Caption = Format(DataqSdk1. SampleRate, "0.00")

End Sub

Private Sub Stop_Click()

DataqSdk1. Stop

End Sub

Private Sub DataqSdk1_OverRun()

'eventually you get an overrun error when running this with a DI-720 USB

Label1.Caption = "OverRun error! Data has been overwritten!"

DataqSdk1. Stop

End Sub
