Abstract
A portable terminal for plugging into a well production control system for displaying data from the control system and for entering data into the control system. A liquid crystal display module on the terminal displays both graphic and printed data. A keyboard on the terminal provides a means for entering data and control signals into the control system. A temperature compensating circuit adjusts the brightness contrast on the display module so the terminal can be used outdoors over a wide range of temperatures.
