Eliminating the need for a keyboard or mouse to access or enter data, call up screens, or control the computer, ST3500 Serial Graphics Terminal lets users interface directly by means of a finger or pointer. Enclosed in a rugged NEMA 4/12 (IP65) rated cast aluminum frame, the terminal requires no external fans or filters and is designed for use in harsh environmental settings. This lightweight system can be mounted almost anywhere, including shop floors, swing arms, pedestals, workbenches, etc. It features 16 levels of character zoom, text display on any 45° angle, normal and slanted fonts, and screen clipping and viewporting. Other features are inverse video, area flashing, and two pages of video memory for quick screen updates.
