TIP products are infrared touch panels designed to fit most flat panel display technologies. the touch panels are a matrix of infrared diodes and detectors, scanning electronics, micro-processor controller, bezel/optical filter assembly and hardware to mount the touch panel and controller to the flat panel display. these touch panels are ideal for many applications including medical instrumentation, machine or process controls, point of sale devices, public information displays, banking and military. vishay dale ? TIP touch panels have a unique patented scan- ning l9ogic system that makes them virtually immune to most lighting environments. optional pc based software (tbdriver, a dos mouse emulator; and twdriver, a windows ? mouse emulator) provide simple touch panel integration. windows ? is a registered trademark of the microsoft corporation. environmental specifications operating temperature: 0 c to + 55 c. storage temperature: - 55 c to + 85 c. relative humidity: 10 - 90% non-condensing. *other user specified filters will be designated as "s". contact factory for availability. any "s" filter designation will requir e a factory assigned dash number suffix. filters a-d are plastic. glass filters may be available on selected models. note: many additional touch panel options available to fit color lcd's and other display technologies. please contact factory for assistance. xxx dash number (if required) a filter * matrix 3216 3220 3224 3526 a = non polarized, gray b = polarized, gray c = non polarized, amber d = polarized, amber s = special - contact factory touch points 63 x 31 63 x 39 63 x 47 69 x 5 1 touch panel display technology eld eld eld eld manufacturer finlux planar finlux planar sharp sharp planar pixels 512 x 256 640 x 400 640 x 480 640 x 480 part number md512.256 el6648mss md640.400 el8358hr lj640u27 lj64zu49 el7768ms designator fa pa fb pb sa sb pc TIP model 3216 matrix fa display designator ordering information

(when beams are blocked on only one axis, they are ignored and not reported to the host.) the controller determines the coordinates of the touch point and reports them 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. 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, software handshaking, baud rates and auto-baud features are jumper selected. the user initializes the desired report modes and requests reports when 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 to the bezel and a bezel to front panel gasket is includedto provide a splash proof seal. command set (a bridged) 11h 13h 20h 21h 22h 23h 24h 25h 26h 27h 28h 29h 2ah 2bh 2ch 2eh 2fxxh 34h dc1, ctl q, xon software handshaking dc3, ctl s, xoff, software handshaking enable exit point mode disable exit point mode (default) enable enter point mode disable enter point mode (default) enable continuous mode/disable tracking disable continuous mode (default) and tracking enable touch panel disable touch panel (default) request failed beam report enable automatic report transfer disable automatic report transfer (default) request one coordinate report reset touch panel disable beeper (default) sound beep, xx = duration (00h to ffh) enable tracking mode/disable continuous dimensions in inches [millimeters] touch frame viewing area 7.9 x 4.1 [200.66 x 104.14] 8.0 x 5.2 [203.20 x 132.08] 7.8 x 5.9 [198.12 x 149.86] 8.6 x 6.4 [218.44 x 162.56] d 5.67 [144.02] 6.950 [176.53] 7.086 [179.98] 7.532 [191.31] b 9.608 [244.04] 9.748 [247.60] 9.680 [246.0] 10.404 [264.26] c 4.86 [123.44] 6.238 [158.45] 6.687 [169.85] 7.311 [185.70] model 3216 3220 3224 3526 b a d c viewing area
