E271-2202 Micro Channel Controller 23
Selecting the Base I/O Port
The E271-2202 uses eight consecutive I/O ports. The Base I/O Port is determined
by running the "automatic configuration" on the PS/2 Reference Disk. An Adapter
Description File (.ADF) is included on the ELODEV User's Disk (1.5 or later), the
MonitorMouse for OS/2 disk (2.0 or later), and the SmartSet Companion Disk.
See the installation instructions in the ELODEV or MonitorMouse for OS/2
manuals, or Chapter 3 in this manual for instructions.
Selecting the Interrupt (IRQ)
The E271-2202 may be operated in either Polled or Interrupt Mode. The Interrupt
(IRQ) is determined by running the "automatic configuration" on the PS/2
Reference Disk. An Adapter Description File (.ADF) is included on the ELODEV
User's Disk (1.5 or later), the MonitorMouse for OS/2 disk (2.0 or later), and the
SmartSet Companion Disk. See the installation instructions in the ELODEV or
MonitorMouse for OS/2 manuals, or Chapter 3 in this manual for instructions.
By default, Interrupt Mode is selected. If you wish to use the controller in Polled
Mode, run the "change configuration" on the Reference Disk, and change the IRQ
to "None".
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.
