The SMT is the rugged low-cost member of the Transtech Systems family of panel mount terminals. It is a rugged, fully functional ASCII terminal that is specifically designed for industrial applications. The SMT is flexible — its menu-programmable function keys can transmit a user programmed character, and host equipment has direct control of cursor movement and appearance, clearing all or part of the display. 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. As with all Transtech Systems terminals, the SMT is remarkably rugged. Its case is molded from General Electric Valox® 420, one of the most durable, chemical-resistant materials available and, when properly mounted, NEMA 4/12 compliance is assured. The keypad surface is securely framed and clamped into place to ensure excellent splash resistance and prevent curling or peeling of the keypad overlay. Stock and custom keypad layouts are available.
