• Manufacturer: Vishay

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
electronics, a microprocessor based controller, a bezel and
optical filter assembly, and hardware to mount the touch panel
assembly 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 determines 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 effectively 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 coordinate 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
scanning 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.
handshaking, software handshaking, baud rates, and X, Y
coordinate invert features 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” filters 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 perimeter of the filter is bonded

Hardware
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

The busy indicator from the host may be changed from CTS
to DSR by changing the position of the jumper at W3.
