Vb.net 无法连接到Stratos 2700电子秤/扫描仪

我连接到霍尼韦尔Stratos 2700电子秤/扫描仪时出现问题。我正在使用霍尼韦尔提供的库HHP，需要一个XML文件来配置它，但是我无法连接到磅秤/扫描仪

我正在使用以下代码：

Public Class Form1

   Private WithEvents mScanner As New HHP.PointOfService.ServiceObjects.Scanner.HandHeldScanner
   Private WithEvents mScale As New HHP.PointOfService.ServiceObjects.ScaleSO.HWScaleSO

   Private str As String
   Public Sub reader()

   End Sub

   Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
      Try

         mScanner.Open()

         mScanner.AssignLogicalname = "scannerABC"

         If (mScanner.State = 1) Then
         End If


      Catch excp As Exception
         Console.WriteLine(excp.Message)
      End Try

   End Sub
End Class

我收到此错误消息：

“异常类型‘Microsoft.PointOfService.Management.Explorer’”
