That depends on the POS system you have. What type of kitchen display or kitchen display “system” will you be using?
I have seen kitchen displays done two different ways: In our software and a few other systems, the kitchen display is part of the order entry program or other software that you run on a computer. In this case, the bump bar works like (emulates) a keyboard on the computer and the screen is a computer display. The other type of kitchen display uses a controller box that is connected to a cash register or POS system, which in turn is connected to remote boxes with a display plugged into each. This type of kitchen display “system” requires a proprietary bump bar and screens, not the keyboard type of bump bar or a standard computer display.
