touchscreen absorbs a portion of the wave at the touch location. The touchscreen
controller's microprocessor analyzes the resulting change in the received signal
and determines the touch coordinates. The IntelliTouch touchscreen can sense
both touch location and touch pressure.
A touchscreen controller is required for both technologies to provide touchscreen
drive signals, convert received analog signals into digital coordinates, and
transmit coordinates to the PC. There are several types of controllers.
Serial controllers use a standard RS-232 port and are baud rate selectable. They
can be mounted anywhere; for example, externally (in separate enclosures) or
inside display enclosures.
Bus controllers plug directly into a card slot within an IBM PC, PS/2, or
compatible computer, so external packaging and power is not required. Bus
controllers are address and interrupt (IRQ) selectable and are available for PC-Bus
(ISA/EISA) and Micro Channel architectures.
The software on the Elo DOS and Windows Driver Disk supports the Elo
touchscreen controllers listed below. E281{A}-4002 refers to both the E281-4002
and E281A-4002 controllers. Likewise, E281{A}-4025 refers to both the E281-
4025 and E281A-4025 controllers.
