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.
The DE-BT 1200 industrial terminal is used as a display and input terminal. Since it is simply a terminal, a host system (such as the prosys/2 process control system) is required to control it. This can transmit the corresponding messages/commands to the DE-BT 1200 via different communication channels. After it receives a message, the display is updated for the user. If an input field is on the screen currently, it can be edited using the membrane keypad or a barcode scanner before the host system queries the entered data.
