Probably (check in the documentation) the 'Customer Display Pole' manufacturer provides a virtual serial port driver fot its USB (at least a library should be provided, again, have a look at the documentation).

First you have to configure the device. Use the below link for the configuration.

http://www.seanliming.com/Docs/Articles/POSdotNET/MSR%20Application%20for%20the%20eoA7330D%20Rev1.pdf

This is the code for the Line Display Unit
Make sure that you have added the Microsoft.PointOfService library to your reference list.
You have to install the Library first.
After the installation, normally it can be found in C:\Program Files\Microsoft Point Of Service\SDK directory

using Microsoft.PointOfService;

private const string WelcomeMessage = "Welcome\r\n";
private PosExplorer posExplorer;
private LineDisplay posLineDisplay;
private DeviceInfo posLineDisplaydevice;

public void LineDisplayUnit()
{
this.posExplorer = new PosExplorer(this);
this.posLineDisplaydevice = this.posExplorer.GetDevice("LineDisplay", "POSIFLEX_LINEDISPLAY");

try
{
this.posLineDisplay = (LineDisplay)this.posExplorer.CreateInstance(this.posLineDisplaydevice);
this.posLineDisplay.Open();
this.posLineDisplay.Claim(1000);
this.posLineDisplay.DeviceEnabled = true;
this.posLineDisplay.DisplayText(WelcomeMessage);
this.posLineDisplay.DisplayTextAt(2, 1, this.LeftAlign("Amount", 7) + this.RightAlign(this.GrandTotalAmount.ToString("0.00"), 12));
this.posLineDisplay.Close();

}
catch (Exception)
{

}
}

Now you can display text using your Display.

Done.
