Worth Data WDP Keyboard Wedge Reader Users Manual For Model P11/12 For Models purchased prior to 8/00
Introduction Worth Data' WDP Readers are versatile bar code readers that attach to the IBM PC, XT and AT; all IBM PS/2 Models; any PC keyboard-compatible or buscompatible unit; and all Macintosh ADB models. The WDP provides bar code input data to any host computer program exactly as if the data had been typed at the keyboard, including function and control key support.
Chapter 1 Installation Components of WDP Reader In the event the shipping box shows damage on arrival, please note the damage on the carrier's receipt log. Open the box and inspect the contents for damage. If there is visible damage, or if the unit fails to work, contact us with the details of the trouble; we will be happy to send you a replacement. The contents of your WDP Reader shipment should include the following: 1.
Installation The several methods of WDP attachment are: • External Wedge The Reader is placed near the computer, and is connected between the computer and keyboard. Velcro is included for convenient attachment to your computer, monitor, desk, etc. Bar code data is received via the computer's keyboard port. • Internal Installation on PC (P11/12) The WDP Reader Models P11/12/P01 have a printed circuit board which can be removed from the case and mounted in any unused PC's ISA slot.
External Wedge Installation on PC or Mac 1. Unplug the keyboard cable from where it plugs into the back of the computer, and note its location. (Note: the PC's F30/1 Y cable is convertible from a 5 pin cable to a 6 pin minidin by simply switching the adapter from one side of the Y cable to another, so match your keyboard requirement. Be sure not to plug into the mouse port by mistake. 2. Plug the keyboard cable into the "Y" cable's round female DIN connector. 3.
USB Installation on a PC or Mac If you are attaching a WDP to a computer which doesn't have a traditional keyboard port, (5 or 6 pin din on PC or ADB on Mac), and only has a USB port for attaching a keyboard, you must use the Wedge Saver to bridge the WDP to the USB port. When you plug the Wedge Saver into the USB port, Windows-98 or the Mac will sense the new device and proceed to install the necessary software. You don't need any additional drivers other than what is already on Windows or Mac OS.
Chapter 2 WDP Reader Setup Configuring the WDP Reader for your computer and application... WDP Reader Setup Menu Turn on your computer: You should hear three beeps -- an indication the WDP Reader is functioning correctly. Find the laminated Reader Setup Menu sheet and look it over. (For bar code slot scanners, the Reader Setup Menu is a deck of bar coded cards.
Using the WDP Reader Setup Menu 1 If you have never scanned before, refer to Appendix K for Scanning Instructions. To configure your reader using the Reader Setup Menu, you must first scan the Start Setup code at the top left corner. Do this now. You'll hear two beeps. During Setup, nothing will be transmitted to your omputer; the Reader Setup Menu codes are strictly for configuring the reader. If you did not hear two beeps, try scanning the code again, until you hear the two beeps.

Preamble A "Preamble" is a user-specified data string transmitted at the beginning of each bar code. For example, if you specify the preamble @@ and read data of 123456, "@@123456" would be transmitted to your computer. The default is no preamble. To select a preamble, scan up to 15 characters from the "FULL ASCII MENU" on the back of the Reader Setup Menu, and then scan SET when you're done.
you'd scan a 1 and then a 2. Next, the break code. Let's say your computer uses keycode 2 break codes of F0 followed by the make code. Finally, a right apostrophe to mark the end of the scan codes. ` 1 2 F 0 1 2 ' (scanned from the Full ASCII Menu) The preamble is limited to 15 characters. As the single scan code example above uses eight characters, you can see that you can't put very many keyboard scan codes in the preamble.
See the previous page's "emulating special keys in the preamble" section. A final use of the Preamble/Postamble is to enter a minimum/maximum length check for bar code data read. Use the Preamble or Postamble by entering |nnmm where "|" is ASCII 124, "nn" is the two digit minimum to be read and "mm" is the two digit maximum to be read. Data Transmission Timing None Short Short Medium Medium Long 0 1 2 3 4 Timing does not apply to Mac ADB or any USB attachment.
Use None (the default), if you don't have a MagStripe scanner. If you have a singletrack scanner, use 1, 2 or 3 to match its track. If you have a dual-track scanner and want to read both tracks, use 4 for tracks 1 and 2, or 5 for 2 and 3. Use 6, 7 or 8 if you have a dual-track scanner but want to read only track 1, 2 or 3 respectively. For all Driver's licenses,(including California) use 8 or 9. See page 21 for more information on the MagStripe scanner.
Terminator Characters Enter (carriage return) None Tab 0 1 2 Depending on your application, you may wish the WDP Reader to transmit bar code data to your computer with an Enter (carriage return), a Tab at the end, or with no extra terminating character at all. If you need a terminator character other than CR or HT (such as LF for UNIX), you can get it by specifying None here and then selecting your desired terminator character(s) through the Postamble specification.
Testing the WDP reader with your computer Windows and Mac users should use the Notepad or a text editor so that the scanned test data will be "typed" on the screen where you can see it. Similarly, DOS users should scan at the DOS prompt or while in a text editor. Bar-code wands, laser scanners and CCD touch scanners: If you are new to scanning, read Appendix K -- Scanning instructions, and then scan the Test Label at the bottom of the page.
Chapter 4 Scanners and Scanning Technique Wands Matching your wand to your bar code type The WDP Reader comes with a low, medium or high-resolution bar code wand, or a medium-resolution wand specially designed to read through plastic or glass, depending on your application.
Wand Scanning Technique Using the illustration as a guide, follow these tips for proper scanning with a wand: 1 Hold the "wand" as you would a pencil, lightly placing your fingers around the wand. If you do not see a red light at the tip of the wand, check to make sure that you are using a VISIBLE light wand, not an INFRARED light wand. Infrared wands show no light at the tip of the wand. 30 2 Your scanning should start in the white space about ¼" to the left or right of the bar code.
Using the Bar Code Slot Scanner Depending on your application, you may wish to use a slot scanner as your bar code input device instead of or in addition to a wand. Worth Data makes a bar code slot scanner that plugs into the WDP Reader's Wand port, and is designed for reading bar codes printed on badges or ID cards. It can also be used for reading bar codes on file folders, envelopes and any other thin, flat surfaces with bar codes printed along an edge.
Using the MagStripe Slot Scanner The MagStripe Slot Scanner options (track 1, track 2, track 3, or track 1 and 2 or 2 and 3 or Track 1/2/3) enable the WDP Reader to read credit and other magneticstrip cards without disconnecting or disabling the bar code wand. It's a stationary scanner which reads tracks 1 and 2 of magnetically-encoded cards meeting the standards defined by ANSI x 4.13, ANSI x 4.16 1983, ISO 3554 and ISO 2894.
Laser and CCD Scanners Wand scanners can satisfy most bar code reading needs. However, we also offer Integrated Laser Wedge Readers and the Integrated CCD Wedge Reader (complete WDP Readers built into a laser scanner and CCD scanner) as well as laser and CCD scanners that plug directly into WDP Reader wand ports. Laser scanners add these abilities to the WDP Reader: • Fast reading of difficult bar codes.
Remember, even though momentary exposure to these low-power, visible-light lasers is not known to be harmful, youmust never stare into the beam or aim it into anyone's eyes. See the following pages for tips on solving problems with laser and CCD scanners and difficult codes. AVOID EXPOSURE LASER LIGHT IS EMITTED FROM THIS APERTURE CAUTION ACHTUNG LASERSTRAHL, LASERCLASSE 2, NICHT IN DEN STRAHL BLICKEN. LUMIERE LASER – NE PAS REGARDER DANS LE FAISCEAU APPAREIL A LASER DE CLASSE 2.
ND STA F /OF ON CCD Scanners The F86 CCD Scanner or the WDP P16 Integrated CCD Reader can also mount in the stand, but the bar code must be presented within 0-4" of the scanner. These quick, durable units(F86 CCD Scanner) work like a laser, but with more limited range. Just aim the scanner at the bar code and by aligning the top of the rather wide beam so that it is within the bar code, pull the trigger and a read occurs instantly. There are 50 scan attempts per second made.
The Integrated CCD Wedge Reader is a complete WDP Reader built into the F86 CCD Scanner. Just plug it in between your computer and keyboard and you're ready to go. It works with any PC keyboard-compatible computer and all Macintosh models. Tips for using CCD’s and Lasers: The CCD scanner works best when positioned about 3" from the bar code. The operating range is about 0-4" for most codes. It can read curved and uneven surfaces well.
Laser scanner options: "Double-scan checking": To minimize the possibility of misreads with very poorly printed bar codes or when reading through windshields, you have the option of forcing the WDP to keep reading until it gets two results that are exactly the same. This "double scan checking" takes a little longer, but it will eliminate misreads. To activate double scan checking: Scan Start Setup Scan Code 39 Scan E to enable double scan checking.
Chapter 4 Special Features Function and Control Key Support The WDP Reader can also transmit key sequences for function, control, alt (command and option keys on Macs), cursor and shift keys, for ease of use with the many software packages using these keys for menus or commands.
Shift, Ctrl and Alt keys Shift, Ctrl and Alt keys require three sequences 1) The ON code generated when the Shift, Ctrl or Alt key is pressed. 2) The other key to be used in conjunction with the Shift, Ctrl or Alt key. 3) The OFF code generated when the Shift, Ctrl or Alt key is released. For example, to properly encode a bar code sequence for Ctrl-C, you would create a bar code of Ctrl ON, C, and Ctrl OFF (control character FS, C and control character GS).
Accumulate Mode Accumulate Mode is an option (which can be enabled or disabled using the Reader Setup Menu's Code 39 section) allowing the reader to accumulate multiple bar codes in its buffer, then transmit them to the computer as if they had been a single bar code. This is useful for entering quantities and other variable data. It works with Code 39 only, and can't be used with a check digit. When the reader reads a bar code with a leading space, it beeps and buffers the data without transmission.
Chapter 5 Troubleshooting A reader installed in Wedge mode (external or internal) doesn't beep three times when you power up your system, or the keyboard locks up, or you get a "keyboard error" or "301" message. • Check the cable connections to make sure everything is plugged in securely. With a PC, make sure the keyboard cable is plugged into the keyboard port rather than the mouse port. If on a Mac ADB, be sure the tagged end of the Y cable goes to the ADB port.
Extra characters at the beginning or end of your bar code data • Clear the Preamble and Postamble. • Make sure you haven't enabled transmission of any start/stop characters, checksums, leading digits or terminator characters that you don't want transmitted. For UPC-E, select Compressed transmission if you don't want it padded with extra zeros. The reader transmits incorrect data to the screen • Reread page 12 and make sure you chose the proper Computer Interface.
• Erratic or low read rates can also result with systems that supply unusually low current or voltage to the keyboard. To test for this, turn your system off, disconnect the keyboard from the "Y" cable, and turn it back on. Then try reading the same bar codes. The system will probably be in a keyboard error state and not display the bar code data on the screen, but all you're interested in is listening for the beeps that signify good reads.
open outward l Appendix A Opening the WDP Case Use the illustrations below as a guide while removing the WDP Reader's circuitboard from its case. Turn your WDP Reader upside-down, and unscrew its single phillips screw. Insert unscrew tilt screw and pull up to open lid a fingernail, credit card edge or small screwdriver blade into the gap between the base and side of the case, and gently use it as a lever to lift up the edge of the base. Then grasp the edge of the base and open it outward like a door.
Appendix B ISA Internal Board Installation Slot Installation with Keyboard Cabling The WDP Reader can be kept out of the way by removing it from its case and mounting it in a PC's ISA slot. It can use the slot for physical mounting only, and doesn't communicate with the bus. Cables connect it between the computer and keyboard, and bar code data is received via the computer's keyboard port.
The connections for Internal Wedge installation on a PC should be as shown below. If you have a laser scanner, CCD scanner or bar code slot scanner, it will plug into the wand port instead of the wand. (If you have a MagStripe slot scanner, see page 21 for its installation instructions.) Be sure to store the WDP Reader's case in a safe place: If you need the slot in the future, or upgrade to a system without PC-style expansion slots, you can easily replace the reader in its case for external mounting.
Slot Installation with Bus Communication For computers running DOS, the internal WDP Reader can be mounted in any unused ISA slot and jumpered to communicate with the bus directly. Internal Bus installation is normally a factory-special order (WDP Model P31/32) which includes BusKey software but no reader case or Velcro for mounting the case.
Appendix C Jumper Settings Your WDP Reader is shipped with its jumpers set to match the configuration (scanner type, interface method, etc.) you ordered. Why might you need/want to check or change jumper settings? If you change your scanner type, or install a second scanning device, you may • need to change some jumper settings. • If you're going to install the WDP Reader in Bus Interface mode, you may need to change the Interrupt Number and Port Address jumpers.
JP4 - Interrupt IRQ 2 IRQ 3 IRQ 4 IRQ 6 IRQ 5 JP5, the Port Address jumper: The WDP Reader in Bus Interface mode can use any of four different port addresses: hex 220, 240, 2C0 and 2E0. The default setting is 220, which most people will be able to use with no problem. Occasionally a tape controller, bus mouse, network board, real-time clock or other add-on may be using address 220 (compare add-on board switch settings with the manuals) and you'll need to choose another.
JP8, the Laser (Decode Light)/Wand jumper: W Use the W jumper setting if you have a wand, touch scanner or bar-code slot scanner connected to the Wand port, or if you'll be using a wand and laser scanner interchangeably with the Wand port. This is the default setting shipped on the WDP P11/12. Using a laser scanner with the W setting causes the scanner's decode light to be on all the time.
Appendix D Specifications for Code 39 Code 39 (or Code 3 of 9) is the de facto standard of non-retail American industry. It is widely used in the automotive industry (AIAG specifications) as well as in government and military applications (LOGMARS 123ABC specifications). Code 39 is flexible, features a large character set, variable data length and density, and bi-directional readability. Code 39 is extremely accurate; substitution errors are almost nonexistent.
Mod 43 Check Character Standard Code 39 can be printed with a "Mod 43 Check Character". This Mod 43 check character cannot be used with Full Ascii Code 39. The check character is derived by assigning a value to each character in the data to be bar coded from the table as follows: Char Value Char Value 0 1 2 3 4 5 6 7 8 9 A 0 1 2 3 4 5 6 7 8 9 10 B C D E F G H I J K L 11 12 13 14 15 16 17 18 19 20 21 Char Value M N O P Q R S T U V W 22 23 24 25 26 27 28 29 30 31 32 Char X Y Z .
Full ASCII Extension to Code 39 "Full-ASCII Code 39" expands the Code 39 character set to include all 128 ASCII characters. Symbols 0-9, A-Z and punctuation characters . and - are identical to their Code 39 representations. Lower-case letters, additional punctuation characters and control characters are represented by sequences of two Code 39 characters.
Appendix E Codabar a29934567a Codabar is widely used in libraries, blood banks, the cotton industry and transportation industries. Its' character set consists of numbers 0 through 9, and punctuation characters + . - / : and $. Symbols a, b, c, d, t, n, * and e are used as start and stop characters. Characters are constructed of four bars and three spaces. Codabar is a numeric-only code, but different combinations of start and stop characters can be used to identify different types of labels.
Appendix F Code 128 Specifications Code 128 is a very powerful bar code, combining an extensive character set and variable length with compactness and error checking. The character set contains all 128 ASCII characters with each character made up of three bars and three spaces. Each element (bar or space) AB123456 varies from one to four units in width, totaling 11 units of width per character.
MOD 10 UCC 128 is enabled by scanning the appropriate bar codes on the TriCoder Setup Menu or by keypad in the PROGRAMMING MODE "Change Setup" option. If MOD 10 UCC 128 is enabled, you will NOT be able to read a standard Code 128 bar code that does not have the Function 1 character and the Mod 10 check character. UCC/EAN Code 128 Serial Shipping Container Code The UCC 128 specification is used extensively by the retail industry.
Appendix G Interleaved 2 of 5 Code Interleaved 2 of 5 Code is a numeric-only, even-number-ofdigits bar code. It is widely used in warehouse and industrial applications. A combination of five elements, two wide and three narrow represent each character. Odd-number 123456 position digits are encoded in the bars, even-number positions in the spaces.
5. Add the results of steps 3 and 4: 9 + 48 = 57 6. Subtract the result of step 5 from the next highest multiple of 10: 60 - 57 = 3 7. The checksum becomes the low-order digit: 19873 8.
Appendix H UPC Specifications t56789rDEFG>W +67L9NOrFG?@A?u UPC symbols are found on almost all grocery products and many other retail items. The UPC code most people are familiar with (UPC-A) is a fixed-length (12 digits) numeric only code, with the first digit controlled by UPC coding assignments and the last digit a checksum. UPCE and UPC-E1 are variations of the standard UPC-A code. Each digit is constructed of two bars and two spaces.
The leading Number System Character, (the first number of the 11 digits to be entered) should conform to these UPC assignments: 0,6,7 Regular UPC 12 digit codes with numbers assigned by the UPC Council. (Do not use 0 as the leading number for in-store marking). 2 Store-marked random weight items of meat and produce. 3 Reserved for National Drug Code and Health Related Items. 4 Use this leading digit for in-store marking of non-food items. 5 Reserved for coupons.
ISBN specifications are available from: American National Standards Institute Customer Service 11 West 42nd St. New York, NY 10036 http://web.ansi.org document ISO 2108:1992 $26.00 The UPC/EAN checksum character The last character in a UPC-A, UPC-E, UPC-E1, EAN-13 or EAN-8 bar code is the checksum.
UPC-E Checksum Calculation Use the sample data of 123456 to demonstrate the UPC-E checksum calculation: 1.
Appendix I MSI/Plessey Specifications Plessey is a variable length numeric only bar code. MSI Bar Code is a variable length, numeric-only code with an automatically appended Modulus 10 check digit. MSI is sometimes called Modified Plessey Code. If the user specifies an additional check digit, the MSI code can be 14 digits long, otherwise it has a maximum length of 13 characters.
The MSI Mod 11 check digit is calculated as follows: The example bar code data is: 943457842 1. Assign a checking factor to each number, starting with the units position of the number (in this example, the 2) up to the highest order position (the 9). Use checking factors of: 2,3,4,5,6,7,2,3,4,5,6,7... 2. Multiply the checking factor with its assigned number and add the products: 4 + 12 + 32 + 35 + 30 + 28 + 6 + 12 + 36 = 195 3. Divide the sum by 11 195/11 = 17 remainder 8 4.
Appendix J Code 93 Specifications Code 93 is variable length, continuous, bi-directional, compact code. Code 93 is an alphanumeric bar code which consists of 43 data characters (0-9,A-Z,$/+%.and Space), 4 control characters, and a unique start/stop character. The entire set of 128 ASCII characters is represented in Code 93 using combinations of control characters and data characters. % / a n d + .
Appendix K ASCII Code Equivalent Table The 128 ASCII codes and their 3 digit decimal equivalents are detailed in the table below.
Appendix L Firmware Upgrades open outward li This section applies only to the WDP P11/12 and the WDP P01, the separate external box decoder models. It does not apply to the Integrated WDP Models. Occasionally it will be necessary to get firmware fixes for problems discovered with the external WDP Reader, especially in the early stages of each advance in development. This is accomplished replacing the EPROM, a chip which is to replace the similar chip on the board of the WDP's decoder box.
Before inserting the new EPROM, notice that the EPROM has a small groove in one end; the end with the groove in it must match the groove in the socket which it is to be inserted into. Don't insert the chip backwards -- line up the groove in the chip to be on the same side as the socket's groove. You may need to slightly bend into the center the legs of the EPROM so that they can be inserted into the socket. Place the chip into the socket and begin to lightly push the chip into the socket.
