Bus Controller
The 2201 controller is shipped jumpered for a Base I/O Port address of 280
(hex) and Polled Mode. An interrupt (IRQ) is normally selected by software if
you are using Elo device drivers. No jumper changes are required, with the
possible exception of an E271-2201 controller reconfigured for E271-141
emulation. See Appendix B for jumper settings.
If the system does not boot properly after you install the E271-2201 controller,
try removing the IRQ jumper if one was installed. If the system still does not
boot, try changing the Base I/O Port address jumpers to another value, such as
380 hex.
If accessible, the controller’s diagnostic LED’s can verify controller operation.
See “Diagnostic Codes” on page A-78.
Using the BUSSTAT Utility
BUSSTAT is a DOS utility included with most Elo driver software. It is also
available by downloading the file DIAGS.ZIP at
www.elotouch.com/Support/
dnld.asp#dos
. Use BUSSTAT to verify basic hardware functionality. Detailed
instructions for using this utility can be found in the BUSSTAT section of the
DOS and Windows Driver Guide available at
www.elotouch.com/support/
dwnldmnls.asp
. If you are not running under DOS, boot your PC from a DOS
diskette before running BUSSTAT.
BUSSTAT is a Polled Mode program and can be run even if no touchscreen
driver is loaded and the IRQ is incorrect or not selected. Verify the Base I/O
Port address jumpers before using BUSSTAT.
Type "BUSSTAT" and specify your controller model and Base I/O Port
address. BUSSTAT displays the switch and jumper settings for the controller
and then unscaled touch coordinates when the touchscreen is touched. Compare
the displayed settings to those recommended in the software driver manual. If
the Base I/O Port address is incorrect, BUSSTAT may display a continuous
stream of data at a value of 4080 for both the X and Y values.
If the hardware is functioning properly, untranslated (raw) coordinates will be
returned at a constant rate only when the touchscreen is touched. If no data is
displayed on touch, or if data is displayed when the touchscreen is not touched
(either continuously or intermittently), you may have a hardware problem. If
data is being displayed continuously without a touch, try disconnecting the
touchscreen cable from the controller. If the data stops, the problem is with the
touchscreen or cable. If it continues, the problem is controller-related.
Verify that the controller board is properly seated in its slot. Try installing the
controller in another slot. If another controller is available, try it as well. Also
try another computer.
