A Microsoft Windows processor system is the primary controller of the
instrument. The instrument features an XGA resolution flat-panel display, a
transparent touch screen, and a front panel with direct access to commonly used
instrument functions. You can also make complete use of the instrument with a
mouse and a keyboard.
Push-button switches on the Front Panel (FP) board are read by an embedded
microcontroller, which sends the button and knob change information to the μATX
board via a USB path. The FP board consists of the following blocks:
USB controller (Cypress EZ-USB FX1)
FPGA (Altera Cyclone)
Key switch matrix
LED indicators (Tri-Color and Mono-Color)
The Display board supports interconnection between the μATX board and FP
board. Two internal USB ports come from the μATX board. One USB connects to
a touch panel controller. The other connects to a microcontroller on the FP board.
Connectors related to the LCD are also included. The Display board consists of
the following blocks:
Touch-panel controller
Rotary encoder (signal goes to the FP board)
Back light controller
Connector to LCD
