POS LineDisplay Issue when Claim

Question

Hi All,

My code to Show info in PoleDisplay is

DeviceInfo

 

oDevice = myExplorer.GetDevice(DeviceType.LineDisplay, "POSLineDisplay");
oDisplay = (LineDisplay)myExplorer.CreateInstance(oDevice);
if (oDisplay != null)
{
oDisplay.Open();
oDisplay.Claim(1000); // Exception throwing here
oDisplay.DeviceEnabled = true;
oDisplay.ClearText();
oDisplay.DisplayTextAt(line, 0, textToDisplay);
oDisplay.Release();
oDisplay.Close();
}

even the PoleDisplay is Pluggedin and ON still getting the error.

Error Message :
Method ClaimDevice threw an exception.  The device is not connected to the system or is not powered on.

Please help to fix this.

Hi,

How is the pole display connected ? If it is via a serial port, is the service object configured with the correct serial port settings ?
