Figure 3-1. P2 Connector Pin Positions, End View
If you are installing the controller inside a display, for the convenience and safety
of the user, we recommend making a cable which connects P2 to a DB9 female
connector (male connectors are used with external controllers) mounted on the
back of the display. 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 AccuTouch Product Manual
for details.
Touchscreen Connections
AccuTouch
A five conductor ribbon cable is attached to the AccuTouch touchscreen. The
female connector on the cable mates with the controller's 1x5 touchscreen
connection at P3 (see Figure 3-2). If you are installing the controller outside the
display cabinet, you may need to make up a short cable with a connector that
mates with the touchscreen connector, and a connector on the other end to suit the
installation. Depending on the type of installation, you may or may not need to
install transient protection as described below.
Transient protection is required in all installations where it is possible to turn the
display on or off while the touchscreen is disconnected from the controller.
1. If Elo installed the touchscreen, and the controller is external, a cable with
transient protection is already installed, terminated with a DB9 male connector
mounted on the back of the display. You will need a cable from the DB9
connector to the controller. DB9 pin connections for Elo installed touchscreen
cables are:
1-S, 6-X, 7-Y, 8-L, 9-H
2. If you are installing the touchscreen, and the controller will be located inside
the display cabinet, you will need to make a data cable, but no touchscreen
cable is required.
3. If you are installing the touchscreen, and the controller will be outside the
display cabinet, you must make a touchscreen cable with transient protection.
