A.2 Resistive Touchscreen Driver Installation
A.2.1 Hardware
Touchscreen controllers must be configured for the driver prior to instal-
lation. Elo typically ships controllers in a default setup that is compatible
with this driver. Controller requirements are:
Serial
Serial controllers must conform to these minimum requirements:
•
Baud rate-9600 baud.
•
Data format-SMARTSET
•
It is desirable for a full handshaking connection to be established
between the touchscreen controller and the computer, but it is not
required. The controller will function with this driver in a "two-wire",
Receive Data and Ground (RxD and Gnd) configuration. The conse-
quences of a two-wire connection are:
+ Automatic detection of the controllers on serial ports during setup is not
possible
+ Controller information will not be registered in the Property Page of the
Control Panel
USB
* USB controllers require no configuration prior to installation.
* Elo's USB controllers are Human Interface Device (HID) compliant.
The Windows 2000 and Windows XP operating systems have native
HID drivers that provide low-level support for Elo touchscreen control-
lers. An Elo touchmonitor with a USB touchscreen controller installed
will provide the following limited operation with these native HID driv-
ers. Operation of the controller will be limited without the installation
of the software discussed in the next section:
• The mouse cursor will move on the display in response to touch
• The direction of motion on the display will depend on the orientation of
the touchscreen and the defaults programmed into the controller and
the driver
• No "beep" will be heard when the screen is touched
• No Control Panel application is available to configure the operation of
the driver.
