QSI Upgrades Electronics in the QTERM®-G70 and QTERM-G75 Operator Interface Terminals.

Salt Lake City, Utah. 28 February 2005. QSI Corporation is upgrading the electronics in their QTERM-G70 and QTERM-G75 rugged graphic operator interface terminals. Previous terminal hardware was based on a 92 MHz MIPS platform with 4 Mbytes of flash memory and 16 Mbytes of RAM. The new hardware for the QTERM-G75 operator interface terminals features a 400 MHz Intel® XScale™ core platform with 8 Mbytes of flash memory and 32 Mbytes RAM (standard terminals) or a 200 MHz Intel® XScale™ core platform with 8 Mbytes of flash memory and 16 Mbytes RAM (Power-over-Ethernet terminals). The new hardware for the QTERM-G70 operator interface terminals with TFT features a 200 MHz Intel® XScale™ core platform with 4 Mbytes of flash memory and 16 Mbytes RAM. The QTERM-G70 terminals with STN will be moving to a 200 MHz Intel® XScale™ core platform with 4 Mbytes of flash and 16 Mbytes of RAM later this year.

"The XScale™ platform provides a substantial increase in performance," said Ryan Martindale, QSI Engineer. "In particular, the VGA display update performance on the QTERM-G75 is significantly improved."

QSI benchmarks indicate that display update, font rendering and other CPU-intensive activities achieve a 2x to10x increase in performance (measured as time to complete the given task). The outer physical appearance and the functionality of the operator interface terminals will not change. The same interfaces and options are available, and existing Qlarity® applications will run without modification When production STN units using the new platform start shipping, the MIPS platform terminals will no longer be available.

The QTERM-G70 and QTERM-G75 intelligent graphic operator interface terminals are designed for today's rugged industrial and vehicle environments. Featuring Ethernet-enabled color touch screens, these terminals use QSI's object-based programming environment named Qlarity. With Qlarity, it has never been easier to design a human machine interface (HMI) for your application. Use pre-defined objects, edit existing objects or author your own. The QTERM-G70 and QTERM-G75 operator interface terminals can be customized for your application.
