GENERAL DESCRIPTION
Vishay Dale Electronics TIP products are infrared touch panels
designed to fit most flat panel display technologies. The touch
panels consist of infrared emitters and detectors, scanning elec-
tronics, a microprocessor based controller, a bezel and optical
filter assembly, and hardware to mount the touch panel assem-
bly to the flat panel display.
These touch panels are ideal for many applications including
medical instrumentation, machine or process controllers, point of
sale devices, public information displays, banking terminals, and
military.
Each panel has infrared LED emitters and phototransistors along
the X and Y axes, forming a grid of infrared light beams across
the face of the display. The first two numbers of the TIP “matrix”
number specify the number of X axis (vertical) beams, and the
last two numbers specify the number ofY (horizontal) beams. The
controller scans the emitter/detector pairs one at a time and de-
termines whether both X and Y beams are blocked, indicating
that a finger or stylus is present. (When beams are blocked on
only one axis, they are ignored and not reported.) The controller
determines the coordinates of the touch point and reports it to the
host computer. By interpolating, a “virtual” beam between two
physical beams, the number of touch points on each axis is ef-
fectively doubled. When an odd number of beams along either
axis is blocked, the coordinate of the center physical beam is
reported. When an even number of beams is blocked, the coor-
dinate of the virtual beam in the center of the blocked beams is
calculated and reported.
Vishay Dale’s TIP touch panels have a unique patented scan-
ning and logic system that make them virtually immune to most
lighting environments.
The touch controller supports ENTER, EXIT, CONTINUOUS, and
TRACKING report modes or combinations of these modes. The
controller also has a beeper output. Hardware handshaking, soft-
ware handshaking, baud rates, and X, Y coordinate invert fea-
tures are jumper selected. The user initializes the desired report
modes, coordinates are reported automatically or upon request
as needed. Several optical filters are standard to provide the
most cost effective filter for each application. “Non-standard” fil-
ters may be specified as well. The filter increases the contrast
ratio of the display and protects the display face and electronics.
Vishay Dale can assist in recommending the optimum filter based
on years of experience as a display manufacturer. The perim-
eter of the filter is bonded to the bezel, and a bezel to front panel
gasket is included to provide a splash proof seal.
Optional PC based software provides simple touch panel inte-
gration (see ordering instructions).

To make a serial communication cable, use insulation displace-
ment connectors (IDC). Press a 10-pin IDC connector onto one
end of the ribbon cable, press a db-9 connector onto the other
end. Match pin 1 of the 10-pin to pin 1 of the db-9, the 10
not used on the db-9.
The busy indicator from the host may be changed from CTS to
DSR by changing the position of the jumper at W3.
