Hi

The cash drawer is connected through RJ11 cable and according to the documentation and OLE Control and shown in the Hardware the Device name is "Devcash"

i used the following code, CDCNTLib is Library provided with the machine

Imports CDCNTLib

Public Class Form1
Inherits System.Windows.Forms.Form


Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim dd As New CDCNTLib.CashDrawer()

dd.Open("Devcash") ' open the device driver
dd.Claim(1000) '1000 is timeout
dd.DeviceEnabled = True
End Sub

End Class

the error is coming "Catastrophic Failure" OLE Exception

Thanks
