W orth Data WDP K eyboard W edge Reader Users Manual For Model P11/12 For Models purchased prior to 8/00.
i Intr oduction W orth Data' WDP Readers are v ersatile bar code readers that attach to the IBM PC, XT and A T ; all IBM PS/2 Models; any PC keyboar d-compatible or bus- compatible unit; and all Macintosh ADB models.
1-1 Chapter 1 Installation Components of WDP Reader In the event the shipping box sho ws damage on arrival, please note the damage on the carrier's receipt log.
1-2 Installation The several methods of WDP attachment ar e: • External W edge The Reader is placed near the computer , and is connected between the computer and keyboard. V elcro is included for convenient attachment to your computer , monitor , desk, etc.
1-3 External W edge Installation on PC or Mac 1. U nplug the keyboard cable from where it plugs into the back of the computer , and note its location. (N ote: 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 requir ement.
1-4 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 W edge Saver to bridge the WDP to the USB port.
2-1 Chapter 2 WDP Reader Setup Configuring the WDP Reader for y our computer and application... T urn on your computer: Y ou should hear three beeps -- an indication the WDP R eader is functioning correctly . F ind the laminated Reader S etup Menu sheet and look it over .
2-2 Using the WDP Reader Setup Menu 1 If you hav e never scanned before, refer to A ppendix K for Scanning Instructions. T o configure your reader using the R eader Setup M enu, you must first scan the Start Setup code at the top left corner . Do this now .

2-8 Preamble A "P reamble" is a user-specified data string transmitted at the beginning of each bar code. F or example, if you specify the preamble @@ and read data of 123456, "@@123456" would be transmitted to your computer . The default is no preamble.
2-9 you'd scan a 1 and then a 2. N ext, the break code. Let's say your computer uses keycode 2 break codes of F0 follo wed by the make code. F inally , a right apostrophe to mark the end of the scan codes. ` 1 2 F 0 1 2 ' (scanned from the F ull ASCII Menu) The preamble is limited to 15 characters.
2-10 See the previous page's "emulating special keys in the pr eamble" section. A final use of the P reamble/P ostamble is to enter a minimum/maximum length check for bar code data read.
2-11 U se None (the default), if you don't have a MagStripe scanner . If you have a single- track 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.
2-12 T erminator Characters Enter (carriage r eturn) 0 N one 1 Ta b 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 T ab at the end, or with no extra terminating character at all.
2-13 T esting the WDP reader with y our computer Windows and M ac users should use the N otepad or a text editor so that the scanned test data will be "typed" on the screen wher e you can see it. Similarly , DOS users should scan at the DOS prompt or while in a text editor .
3-1 Chapter 4 Scanner s and Scanning T echnique W ands Matching your w and to your bar code type The WDP R eader comes with a low , medium or high-resolution bar code wand, or a medium-resolution wand specially designed to read thr ough plastic or glass, depending on your application.
3-2 W and Scanning T echnique U sing the illustration as a guide, follow these tips for proper scanning with a wand: 1 H old the "wand" as you would a pencil, lightly placing your fingers around the wand.
3-3 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. W or th Data makes a bar code slot scanner that plugs into the WDP R eader's W and por t, and is designed for reading bar codes printed on badges or ID cards.
3-4 Using the MagStripe Slot Scanner The MagS tripe Slot Scanner options (track 1, track 2, track 3, or track 1 and 2 or 2 and 3 or T rack 1/2/3) enable the WDP R eader to read credit and other magnetic- strip cards without disconnecting or disabling the bar code wand.
3-5 Laser and CCD Scanners W and scanners can satisfy most bar code reading needs. H owever , we also offer Integrated Laser W edge Readers and the Integrated CCD W edge Reader (complete WDP Readers built into a laser scanner and CCD scanner) as well as laser and CCD scanners that plug directly into WDP R eader wand por ts.
3-6 Remember , even though momentar y exposure to these low-po wer , visible-light lasers is not known to be harmful, youmust never star e into the beam or aim it into anyone's eyes. See the follo wing pages for tips on solving problems with laser and CCD scanners and difficult codes.
3-7 CCD Scanners The F86 CCD Scanner or the WDP P16 I ntegrated 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.
3-8 The Integrated CCD W edge Reader is a complete WDP Reader built into the F86 CCD Scanner . J ust plug it in between your computer and keyboard and you're ready to go . It works with any PC keyboar d-compatible computer and all Macintosh models.
3-9 Laser scanner options: "Double-scan checking": T o minimize the possibility of misreads with very poorly printed bar codes or when reading through windshields, you hav e the option of forcing the WDP to keep r eading until it gets two results that are exactly the same.
4-1 Chapter 4 Special F eatur es Function and Control K ey Support The WDP R eader 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.
4-2 Shift, Ctrl and Alt ke ys Shift, Ctrl and Alt keys requir e 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.
4-3 A ccumulate Mode Accumulate M ode is an option (which can be enabled or disabled using the Reader Setup M enu'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.
5-1 Chapter 5 T r oubleshooting A reader installed in W edge mode (external or internal) doesn't beep three times when you po wer up your s ystem, or the k eyboar d locks up, or you get a "ke yboard error" or "301" message . Check the cable connections to make sure everything is plugged in securely .
5-2 Extra char acters at the beginning or end of y our bar code data Clear the P reamble and P ostamble. Make sure y ou haven't enabled transmission of any start/stop characters, checksums, leading digits or terminator characters that you don't want transmitted.
5-3 Erratic or low r ead rates can also result with systems that supply unusually low current or voltage to the keyboar d. T o 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.
A-1 Appendix A Opening the WDP Case U se the illustrations below as a guide while remo ving the WDP Reader's circuitboard fr om its case. T urn your WDP Reader upside-do wn, and unscrew its single phillips screw .
B-1 Appendix B IS A Internal Boar d Installation Slot Installation with Ke yboard Cabling The WDP R eader can be kept out of the way by remo ving 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.
B-2 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 MagS tripe slot scanner , see page 21 for its installation instructions.
B-3 Slot Installation with Bus Communication F or computers r unning DOS, the internal WDP Reader can be mounted in any unused ISA slot and jumpered to communicate with the bus directly .
C-1 Appendix C Jumper Settings Y our 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.
C-2 JP5, the P ort Address jumper: The WDP R eader 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.
C-3 JP8, the Laser (Decode Light)/W and jumper: U se the W jumper setting if you have a wand, touch scanner or bar-code slot scanner connected to the W and port, or if you'll be using a wand and laser scanner interchangeably with the W and port. This is the default setting shipped on the WDP P11/12.
D-1 Appendix D Specifications f or 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 specifications).

F-2 MOD 10 UCC 128 is enabled by scanning the appropriate bar codes on the T riCoder Setup Menu or b y keypad in the PR OGRAMMING MODE "Change Setup" option. If MOD 10 UCC 128 is enabled, you will NO T be able to read a standard Code 128 bar code that does not have the F unction 1 character and the Mod 10 check character .
G-1 Appendix G Interleav ed 2 o f 5 Code Interleaved 2 of 5 Code is a numeric-only , even-number-of- digits bar code. It is widely used in war ehouse and industrial applications. A combination of five elements, two wide and three narro w represent each character .
G-2 5. Add the results of steps 3 and 4: 9 + 48 = 57 6. Subtract the result of step 5 fr om the next highest multiple of 10: 60 - 57 = 3 7. The checksum becomes the low-order digit: 19873 8.
H-1 Appendix H UPC Specifications 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.
H-2 The leading N umber 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 b y the UPC Council. (Do not use 0 as the leading number for in-store mar king).
ISBN specifications are available from: American National Standards Institute Customer Service 11 W est 42nd St. New Y ork, NY 10036 http://web .ansi.org document ISO 2108:1992 $26.00 The UPC/EAN checksum char acter The last character in a UPC-A, UPC-E, UPC-E1, EAN-13 or EAN-8 bar code is the checksum.
H-4 Because the sample UPC-E code ends in a 6, the insertion digits 0000 are inserted at the sixth digit (insertion position 6): 1234500006 2. Add the N umber System Character of 0 to the sample data: 01234500006 3. Use the UPC-A check digit calculation described in the pr evious section to produce a check digit as if it were a UPC-A code.
I-1 Appendix I MSI/Plesse y Specifications Plessey is a variable length numeric only bar code. MSI Bar Code is a v ariable length, numeric-only code with an automatically appended Modulus 10 check digit. MSI is sometimes called Modified P lessey Code.
I-2 The MSI Mod 11 check digit is calculated as follo ws: The example bar code data is: 943457842 1. Assign a checking factor to each number , star ting with the units position of the number (in this example, the 2) up to the highest order position (the 9).
J-1 Appendix J Code 93 Specifications Code 93 is variable length, continuous, bi-directional, compact code. Code 93 is an alphanumeric bar code which consists of 43 data characters (0-9,A-Z,$/+%.- and Space), 4 contr ol characters, and a unique start/stop character .
K-1 Appendix K ASCII Code Equiv alent T able The 128 ASCII codes and their 3 digit decimal equivalents ar e detailed in the table below . NUL 00 000 SP 20 032 @ 40 064 ‘ 60 096 SOH 01 001 ! 21 033 A.
L-1 Appendix L Firm w ar e Upgr ades This section applies only to the WDP P11/12 and the WDP P01, the separ ate external box decoder models. It does not apply to the I ntegrated WDP Models.
L-2 Before inserting the new EPR OM, notice that the EPROM has a small groo ve in one end; the end with the groov e in it must match the groove in the socket which it is to be inserted into. Don't insert the chip backwar ds -- line up the groove in the chip to be on the same side as the socket's groov e.
