The DE-BT 1200 is a display and input terminal for industrial applications. Since it is simply a terminal, it is controlled by a host system such as the prosys/2 process control system. The host system can transmit messages and commands to the DE-BT 1200 via various communication channels, which will update the display for the operator. If there is an input field displayed on the screen, it can be edited either using the membrane keypad or a bar code scanner before the host system retrieves the entered data.
