Looking for a low-cost, flexible hand held terminal? Specifically designed for industrial applications, the TechTerm™ is a rugged and fully functional ASCII terminal. Menu- programmable function keys will store a total of fifteen selected characters. Your equipment can be used to directly control the terminal using private escape sequences, including cursor movement, appearance, key "click", and several different distinct signal tones from the built-in speaker. Function key definitions and operating parameters are stored in non-volatile memory. Available I/O configurations include RS-232 and RS-422 as well as standard CMOS/LSTTL logic levels. If you do not want to rely on line-power, an optional rechargeable battery or the ability to use commercially available alkaline batteries are both available. A unique built-in retractable hanger provides the ability to easily hang the terminal (line-powered only).
