The 3100 Series Rear Customer Display (RCD) operates by converting recognized data, supplied by serial
communication, into a display message. The supplied data may also contain commands that control the display.
The 3100 Series RCD uses a limited command structure for display control, requiring minimal programming effort.
The table below lists the display control features of the 3100 Series RCD and control codes (in ASCII, DEC, and
HEX expression). The display control command structure, with examples, is described in this section.
