Section 1. Introduction

Congratulations! You have just purchased a quality Matrix Touch (TM) keyboard designed for many years of use as an input device. Your new Matrix Touch (TM) keyboard has many built in switch selectable features that makes interfacing to your application easier and quicker. The Matrix Touch (TM) keyboard with switch selectable outputs can have a basic Row/Column output that looks a like basic switch closure. Or a digital parallel output with a data read strobe selection. Or a RS-232 or RS-422 communication output selection that plugs directly to a serial comms port, and then to Ps2 selection that plugs into a Din six pin connector. This flexibility all designed to get your product or application up and running with the least amount of input hassle. The "On" LED can be used to show power applied, or selected to be off to let other equipment indicate when power is applied. The 2nd key enable has a different set of output codes when the 2nd key is touched allowing less code for a systems programmer. The security key can disable certain touch positions leaving only a person with a security key the ability to use those touch positions. Audible response enable gives the user the option of hearing a touch position being touched. The 20 Position Matrix Touch (TM) keyboard is produced in two basic configurations. One with a minimal amount of emitters and detectors for a 20 position keyboard to give a quality touch at the lowest cost. The second configuration has all of the emitter and detectors to allow the key function and Touch Tract (TM), think of "T" squared as a finger joy stick, to quickly and easily position the cursor, drag, or click on icons on the display device. By having switch selectable features there is no need for batteries or other electronic storage devices. The configuration is checked by the micro processor every 50 milliseconds, so even if a reset or power outage occures the configuation will not change. This simplistic approach allows for a rugged keyboard for the industrial and commercial markets. There is a 2nd enable configuration that allows the keyboard to toggle between two different outputs for each touch position so ASCII keycodes for 0-9, and A-Z, can be produced from the 20 position key matrix. The rugged .080 thick molded polycarbonate housing has been industrially designed to be user friendly, to either be surface mounted or flush mounted, and to fit all applications requiring keyboards that will be tested by users everyday. The housing is coated with a hard coat to protect it from perspiration and other chemicals, hose down and other NEMA 4 requirements, scratches, and UV. A separate color coordinated ABS molded bezel is used when the keyboard is surface mounted, and comes standard in either beige, gray or black to match customers needs. The Matrix Touch (TM) keyboard is designed with state of the art components and made in the USA by Electronic Keyboards, Inc., a company with over thirty years of experience in designing quality products for the industrial and commercial markets.

Section 2. Specifications

The keyboard is 5.20 inches wide, 5.95 inches long, and 1.00 inch thick. It weights 12 ounces. Each of the 20 positions for key text touch areas are .75x.75 inches. The total key text area is 3.00x3.75 inches. 12 VAC @ 150 ma or 5 VDC @ 250 ma. If mounted with supplied gasket it is NEMA 4.

Section 3. Packing List/Parts List

1. Matrix Touch (TM) Keyboard 2. Overlay Protective Cover 3. Key Text Overlay 4. Matrix Touch (TM) Manual 5. Mounting Gasket 6. Color Bezel (if surface mounted)

Section 4. Overlay Installation

If you purchased the quantity of Matrix Touch (TM) keyboards necessary to have a custom Overlay supplied with your keyboard all that is necessary to install the Overlay is to peel off the protective rear cover, align the Overlay with the keyboard making sure the lower edge or right edge of the Overlay is over the two Security Key holes, then position the Overlay in the recess in the keyboard and press firmly in place. If you purchased a generic keyboard with the flexability of you being able to customize the Overlay, then please follow these few simple steps to make a professional looking Overlay. To make up a custom key text Overlay requires an Overlay Protective Cover and the Key Text Overlay, both included with your new keyboard. The Key Text Overlay supplied with your new Matrix Touch (TM) keyboard can be used if the text suits your application. It has punch marks at the top of keys that can have LED Status indicators. By using a .187 diameter single paper punch the you can punch holes at the location of the punch marks to allow the LED Status indicators show through in the locations to fit your application. By using the dimensions of the Key Text Overlay you can print your own overlay with the color and text to fit your application. Once printed and punched to you requirements, place the Key Text Overlay on a flat surface, place the Overlay Protective Cover over the Key Text Overlay, by bending the Overlay Protective Cover in a "U" shape so that the middle of the cover contacts the overlay first. Then slowly press the "U" to a flat position. Then by using a small roller or a piece of plastic press the cover firmly on the overlay. Then if you have the key option you should punch two .156 diameter holes in the position shown on the overlay.

Section 5. Keyboard Installation

The Matrix Touch (TM) keyboard can be mounted either to the surface of an enclosure or wall, or be flush mounted through an enclosure panel. The Mounting Gasket supplied fits both applications. The keyboard can be either mounted with the two Security Key holes toward the bottom in a vertical position or toward the right side in a horizontal position. Do not mount the keyboard with the two Security Key holes toward the top or toward the left whether using the Security Key or not.

Section 5.1 Surface Mounting

By using the supplied Mounting Gasket holes can be transfered to the mounting surface. A one (1.00) inch hole should be punched at the position of the input and output connectors that fit the application. Or a cutout that matches the inside size of the Mounting Gasket can be made. The four (4) inserts in the keyboard housing are for 8-32 screws. Four .187 inch diameter holes should be punched in the mounting surface to accept a screw in these inserts. At no time is it necessary to remove the keyboard rear cover. Removing this cover VOIDS the warranty.

Section 5.2 Flush Mounting

To flush mount the Matrix Touch (TM) keyboard a cutout as shown below must be in the panel centered on the hole pattern as used with Surface mounting on the preceding page, except that the hole size should be .140 inch diameter. The same gasket is used whether the mounting is to be Surface or Flush. To attach the keyboard to the panel four (4) 6-32 flush head studs from Penn Engineering and Mfg. (PEM) can be used, part number FH-632-20. Nuts are then used to secure the keyboard to the panel. This type of installation gives a completely flush look. In applications where a screw head showing on the exterior of the panel does not deter from the aesthetics of the installation four (4) 8-32 screws can be installed from the front side of the panel through .187 inch diameter holes in the location of the holes on the preceding page. In this mounting method output connections can be made by mounting the keyboard directly to the customers PCB with .025x.025 male pin headers soldered at the locations needed, consult factory for dimensions.

Section 6. Feature Selection The switches to activate selectable features of the Matrix Touch (TM) Keyboard are exposed through the rear cover of the keyboard. They are numbered 1 through 12, and can either be on or off.

Section 6.1 Touch Track (TM) - The connections to the host Ps2 type mouse port and Ps2 type keyboard port are shown on page 16. The keyboard layout can be like the right set of keys on a 101 style keyboard, as shown on page 15. Touch Track (TM) and the keyboard function toggle between each other via the upper left toggle (Tog) touch area. They can be used together to input key text data, and cursor positioning, dragging, and clicking, or they can be used standalone only utilizing the keyboard or cursor positioning device. Touch Track (TM) is like a finger being used as a joystick. You position your finger on the neutral zone and then move your finger in the direction you want the cursor to move. When you want to stop movement you can either move your finger back to the neutral zone or lift your finger from the touch area. There are two levels of speed for cursor movement. So for finer positioning use the area closest to the neutral zone, and then move outward to increase the speed of movement. The neutral zone can be used for clicking, by just touching the zone for a single click or by touching the zone twice for a double click. The "LB" key area is the same a the left mouse button, and the "RB" key area is the same as the right mouse button. The draging feature is set by touching the Drag area and then positioning your finger in the neutral zone, then drag the object to the desired location and lift you finger out of the neutral zone. Drag is reset automaticlly when you lift your finger. If you want to drag again then touch the Drag area and follow the same sequence as before. The keykoard can be used to "touch type" because there is no force needed to input data, so rapid data entry can be done. When switch six (6) is in the off position the Touch Track (TM) is enabled.

Section 6.2 On LED Enable - When switch seven (7) is in the on position the "ON" LED is off when the keyboard is powered. When switch seven (7) is in the off position, the "ON" LED is on when the keyboard is powered. In either position the LED can be controlled to be either off or on through the communications link, see Section 10. The "ON" LED is positioned above the key text position in the upper right part of the keyboard when the keyboard is mounted vertically, and above the key text position in the upper left of the keyboard when mounted horizontally. If a different position is needed then via the comms port any one of the eight status indicators can be used.

Section 6.3 2nd Keyboard Enable - When switch eight (8) is in the off position the 2nd feature of the keyboard is enabled. The key text position for this feature is the lower left key when mounted vertically, and the lower right key text position when mounted horizontally. When enabled an output for that position is sent, and until that position is touched again a different code is sent for the other keys. A code for the 2nd position is not sent the same. See Section 11 for the output codes for particular types of outputs. 2nd enable is not an option when using binary output.

Section 6.4 Key Enable and Operation - When the security key is inserted in the keyboard a logic one (+5VDC) is present on pin 1 of output connector J1, and when removed a logic zero (0VDC) is present on pin 1 of output connector J1. Section 10 explains the codes sent through the communications link when using the key. When switch nine (9) is in the off position the keyboard is enabled when the security key is inserted, and when in the on position is enabled whether the security key is inserted or removed.

Section 6.5 Audible Response Enable - An audible responsAe is given for a valid touch of a key text location when switch ten (10) is off.

Section 7. LED Status Indicator Positions Available The twenty position Matrix Touch (TM) keyboard has eight (8) LED status positions that can be controlled by the communications link, either RS-232 or RS-422. The locations are shown in the following two figures, one being for a vertically mounted keyboard and the second being for a horizontally mounted keyboard. The positions are numbered from one (1) through eight (8).

Section 8. Programming Status LED's

The Matrix Touch (TM) keyboard uses a simple but effective programming technique. If the host computer sends an ASCII one (hex 31) the LED in position 1 will be turned on. The keyboard will frame the one and send back >1< to the host computer to show what it received. ASCII codes from one to eight turn on LED's one through eight. If an ASCII zero (hex 30) is sent from the host all LED's are turned off. If the keyboard receives an invalid code, or a wrong code, the keyboard sends back what it received and then a question mark, i.e. if the keyboard receives a "w", it sends back to the host >w<>?<. If the ON enable LED is configured, the host must always send a one (hex 31) to the keyboard if the host has sent a zero (hex 30) to keep the ON LED turned on. The communications setup is eight (8) data bits, no parity, 2400 baud.

Section 9. Power Requirements and Connections

The Matrix Touch (TM) keyboard can be powered by either 12 VAC or 5 VDC at 1.3 watts. When being powered by 12 VAC an internal regulator maintains a 5 VDC to operate the keyboard. If the keyboard is being power by an external +5 VDC then switch twelve (12) must be turned off so the internal regulator output is not powered.

12 VAC - When the keyboard is to be powered by a 12 VAC source, connector J3 pins 9 and 10 are used for the input. Switch eleven (11) should be off and switch twelve (12) must be on. If a ground is needed then it should be connected to J3 pin 7, and switch eleven (11) should be turned on. The 12 VAC transformer should be 250 ma or more.

5 VDC - When the keyboard is powered by a +5 VDC the ground should be connected to J3 pin 7, and the +5 VDC connected to J3 pin 8. Switch eleven (11) must be turned on and switch twelve (12) must be turned off. The size of the DC supply should be 250 ma or more.

Section 10. Communications Link

The communications link is used to send key codes to the host computer and to receive on and off positions of the Status LED's. Section 7 discusses the Status LED's showing position and numbering. Whether communicating with the host computer via RS-232 or RS-422 the setup is eight (8) bits of data, no parity, one stop bit, 2,400 baud, DCE, and Xon Xoff. The key codes are framed being transmitted from the keyboard and the codes being sent from the host computer are not framed. When the security key is inserted into the keyboard an ASCII "I" (hex 49) is sent to the host computer, and when the security key is removed from the keyboard an ASCII "O" (hex 4F) is sent to the host computer, i.e. when inserted <49>, and when removed <4F>.

If the host computer wants to reset the keyboard it sends an ASCII "R" (hex 52). This will reset the keyboard initiating an internal RAM test, reloading of internal ports, and a check of the configuration switches. A reset is as if the keyboard was powered down and then up. If the RAM test fails the keyboard will continue to reset itself until the keyboard is powered down. An ASCII "R" (hex 52) is sent to the host after a reset to show a reset has occured. The Status LED's can be turned off and on through the communication link. This is especially useful when the keys are controlling things that do not have direct visual feedback from the operator location. Say a key initiates a print function on a printer in another room. The host computer can turn on the Status LED associated with that key, and then when the printer is completed its function the host computer can turn off the Status LED to signal the operator that the printer has stopped. This could also be a pump, a drive sequence, a timing sequence, etc. See Section 6 for Status LED numbering and position. All key codes sent from the keyboard are framed, i.e. when sending a hex 32 it is sent <32>. When the LED Status positions are sent from the host computer the keyboard responds with the same position but with reversed greater and less that signs, i.e. the host computer sends position hex 37, the keyboard responds >37<. When 2nd is enabled only the key code is sent to the host when a key is touched. The less than and greater than signs are not sent, i.e. for a "J" touched only the ASCII code "4A" is sent.

Section 10.1 RS-232 - The host computer transmit line is connected to J1 pin 9 which is data incoming to the keyboard, and the host computer receive line is connected to J1 pin 10 which is data coming out of the keyboard.

Section 10.2 RS-422 - The pair of host computer transmit lines are connected to J1 pins 1 and 2 which is data incoming to the keyboard, and the pair of host computer receive lines are connected to J1 pins 3 and 4 which is data coming out of the keyboard.

Section 11. Parallel Output Selection and Corresponding Key Codes

The outputs are on J2 on the rear cover of the keyboard. The 'J2" is molded into the rear cover at the pin one end. Row/Column, Binary, and ASCII outputs share the same connector, and are selected by configuation switch S1. The "S1" is molded into the rear cover at the switch number one end. The outputs are configured by switches 3, 4, and 5, and when configured are either on or off depending on the output selected. The outputs are logic levels of plus five (5) volts and ground, and will source and sink 10 ma.

Section 11.1 Row/Column - The output gives a plus five (5) volts for a make and a zero (0) volts for a break. Row/Column does not have a data strobe, data is valid as long as the finger is in the touch area. The row is horziontal and the column is vertical as viewed from the keyboard touch area side with the top row being four (4) keys wide and the vertical column being five (5) keys high. Viewing the switches with the S1 to the right of the switches, the switches are in an on position when down and in an off position when up. Switch three (3) should be off, switch four (4) should be on, and switch five (5) should be off.
