Additional Information On Pole Displays
Pole Displays, sometimes called customer displays, are used to display information about a customer transaction as items are being entered into the point-of-sale system. This could be price, description, quantity, total, or other information. Customer displays vary in text height, but are almost always 2 rows of 20 characters (2x20).
Pole Displays are also used to help reduce employee theft by providing a verification that items are being properly entered. In more advanced systems, customer pole displays can be used for marketing purposes or to provide communication on if a POS station is open or closed.
An emulation mode or command set is how a pole display interprets the data it gets. Unfortunately, not all pole displays can be configured to suit your needs, and so for those, such as the PartnerTech CD-7720, or Logic Controls pole displays, make sure they verify compatibility with your software developer before purchasing one of their pole displays. Some pole displays, such as the Epson DM-D110 and POS-X Xp8200, allow you to change which emulation mode is active, allowing you to set them up to meet your software's needs.
