RT-21 Console is a download firmware load for any RT-21 that converts that unit into a control console for another RT-21 controller.  Essentially, the RT-21 Console implements a “computer terminal” in an RT-21 unit that sends and receives RT-21 commands over an RS-232 link.  Both the rotor connected RT-21, and the RT-21 Console can control the attached rotator, and view headings.
