SmartSet Technical Reference Manual—Addendum for the E281-2310 Controller
The controller only requires a 2-wire connection, controller Transmit Data (P2
pin 3) and Signal Ground (P2 pin 9). For two-way communications, the controller
Receive Data (P2 pin 5) should also be connected to the host Transmit Data pin.
Data Set Ready (DSR) and Clear to Send (CTS) may be used by the host to verify
controller connections and operation. DSR is asserted when power is applied to
the controller and CTS is asserted when the controller's power-on sequence is
complete. Data Terminal Ready (DTR) and Request to Send (RTS) can also be
connected for full hardware handshaking.
Elo driver software typically requires two-way communication (unless ELODEV's
-p- flag is used), and all four handshaking lines.
If you are installing the controller inside a display, we recommend that you make a
cable that connects P2 to a DB9 female connector mounted on the back of the
display, or use Elo's serial cable P/N 012138. (Male connectors are used on
TouchMonitors with external controllers.) The shell of this connector should be
tied to chassis ground. Use an additional cable from the back of the display to your
serial port.
Elo can provide suitable adapters and cabling. See the IntelliTouch Product
Manual for details.
Touchscreen Connections
A round multi-conductor cable terminated in a 2x6 female connector is attached to
the IntelliTouch touchscreen. One of the following cabling options normally
applies:
If the controller will be located inside the display, the touchscreen cable
connects directly to the 2x6 header at P3 on the controller (see Figure 1,
page 1).
