E271-2210 Serial Controller 15
Hardware Handshaking
E271-2200 and E271-2210 controllers support hardware handshaking. Jumper J3
is used to enable or disable hardware handshaking. If disabled, the controllers
ignore the DTR and RTS lines.
Hardware Handshaking J3
Enabled not installed (shipped setting)
Disabled installed
A software command may also be used to select a wider range of hand-shaking
options. Handshaking options can be saved in NVRAM as a power-on default. See
the Parameter command, page 95, for details.
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 E271-2200 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)
