20 Chapter 2 - Controller Jumper Settings
Choosing Single-Point or Stream Modes
Jumper J4 selects Single-Point or Stream Mode on all SmartSet controllers.
Mode J4
Stream not installed (shipped setting)
Single-Point installed
If Single-Point Mode is selected, a single coordinate pair is communicated for each
touch. No further coordinates are communicated until the finger is lifted (untouch),
and the touchscreen is retouched.
If Stream Mode is selected, the controller sends coordinate pairs continuously until
untouch.
If you are using Elo driver programs, Stream Mode is required.
A software command may also be used to select a wider range of modes. Modes
can be saved in NVRAM as a power-on default. See the Mode command, page 90,
for details.
Selecting the Touchscreen Type
The E271-2201 controller is shipped with jumper J5 installed for E274 AccuTouch
5-wire touchscreens. If you are using a 4-wire DuraTouch touchscreen (no longer
manufactured by Elo), remove the jumper at J5.
Touchscreen Type J5
AccuTouch installed (shipped setting)
DuraTouch not installed
Emulation Mode
If you are using driver software that does not directly support the SmartSet
protocol, the E271-2201 controller can be set up through jumpers for hardware
compatibility with the AccuTouch E271-141 controller (or the DuraTouch E271-
142 controller).
When the controller is in an emulation mode, it will not respond to the SmartSet
protocol. For descriptions of the protocols in the various emulation modes, see
Appendix A.
To select emulation mode, set the J10 jumper as follows:
