Page 2: Introduction
Introduction Worth Data's WDR Readers are versatile serial bar code readers designed for use with all micro and minicomputers. Features of the WDR Reader include: • The WDR Model R22 can be attached between your computer and a terminal, sending bar code data along with keyboard data with LINUX, UNIX and PICK. -
Page 3: Installation
F45-1..serial “Y” cable for connection between terminal and host (See page 42 for pin-outs and longer descriptions) c. A scanner (F52 wand, LI50 CCD, LZ300 Laser or LZ400 Laser) d. A scanner holder. e. A 5-volt power supply (Don't use a non-Worth Data power supply;... - Page 4 Connect the power adapter to the WDR Reader & to an outlet: Be certain to only use a Worth Data power supply; any other power supply will likely fry the reader. Insert the power jack into the WDR Reader's power connector, and plug the other end into an electric outlet.
- Page 5 Your software will need to read the serial port as a separate device, unless you're using an IBM-compatible computer and Worth Data’s PortKey software, which makes serial-port data look to your computer as if it had been typed at the keyboard.
- Page 6 Installing the WDR Reader between a Host and Terminal If you attach the WDR R22 Reader between your computer and a terminal, as shown below, using the F45-1 Serial Y Cable, bar code data will display on the terminal as if it had been typed. The F45-1 Serial Y Cable assumes you already have a dumb ASCII terminal connected to a host computer.
- Page 7 Follow these instructions to connect and configure your WDR Readers for polling. Connect the Worth Data power supplies to the WDR readers and plug the power supplies into your outlets. You should hear three beeps as each WDR Reader is plugged into the wall.
- Page 8 must be assigned a unique ID. The IDs for a WDR Reader and any other Worth Data readers on the same port must be limited to ASCII values 96-127. To set the ID character on a WDR reader, scan the Start Setup and then Set ID Character bar codes from the WDR Reader Setup Menu.
-
Page 9: Configuring The Wdr Reader
Configuring the WDR Reader for your computer and application Find the 8 1/2 x 11" laminated WDR Reader Setup Menu sheet and look it over. This simple menu lets you easily configure the WDR Reader to work with almost any computer system, and to tailor its bar code reading and data format characteristics. -
Page 10: Scanning Techniques
Scanning Techniques Follow these instructions for proper scanning -- to read the Reader Setup Menu bar codes and configure the WDR Reader, you must know the right way to scan bar codes. Wand scanners Start in the white space (quiet zone) to the left or right of the bar code. -
Page 11: Using The Wdr Setup Menu
Laser And CCD Scanning Instructions Using a laser or CCD scanner is basically as simple and intuitive as "point and shoot" at a distance of .5 - 24", depending on the scanner and the density of the bar code. Basically, the CCD and laser scanner's beam must cross every bar and space on the bar code, without touching any other bar codes, as shown in the first example below. - Page 12 scanned bar codes before, read the scanning instructions on pages 10-11 before continuing. 2. Next, choose the topic you want to change an option for, and scan its code. Let's use Beep Tone, at the lower left corner of the menu, as an example. Scan the Beep Tone code now.

Page 18: Baud Rate
Inter-character delays None Short Short Medium Medium Long The WDR Reader can transmit bar code data with five different inter-character delay rates (this is independent of baud rate). Most computers work perfectly with no delay, but with the wide variety of systems out there we have to provide some delay rates. -
Page 19: Stop Bits
Stop bits 1 Bit 2 Bits Set the stop bits to the same setting your terminal is using, or you want to use with your serial port. Protocol None XON/XOFF ACK/NAK Polled – No ACK/NAK Polled with ACK/NAK Host Response Enabled Host Response Disabled "None"... - Page 20 WDR and then compare its calculated checksums with the ones received from the WDR. If they match, the computer transmits an ACK back to the WDR; if they don't match, the computer transmits back a NAK to the WDR. When the reader receives an ACK or NAK, or times out, its LED returns to green.
- Page 21 Set ID Character (For Polling protocol only.) Before a WDR using polling protocol can transmit data to your computer, the computer must poll the reader with that particular reader's ID character. ID characters can be any lower case letter, the punctuation characters {, |, }, ~, or DEL.
-
Page 22: Host Response Delay
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. -
Page 23: Terminator Characters
For example: Suppose you want the WDR Reader to output a hex 92 character every time you scan a 1 (hex 31); you want to remap hex 31 to hex 92, (If you're using 8 data bits, output of 80-F8 codes is possible.) 1) Scan the Start Setup Bar Code 2) Scan the Characters Bar Code on the Setup Sheet. -

Page 25: Test The Reader With Your Computer
Test the Reader with your computer If running Windows, install and run the WDRTEST program distributed with the WDR reader, (or download it from our Website www.barcodehq.com). If you ordered PortKey, use PortKey instead of the WDRTEST program. Now go to Notepad in your Windows programs, and scan data according to below: •... -
Page 26: Using The Bar Code Slot Scanner
Depending on your application, you may want 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 either of the WDR Reader's Scanner or Magstripe ports, and is designed for reading bar codes printed on badges or ID cards. -
Page 27: Using The Magstripe Slot Scanner
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) enable the WDR Reader to read credit and other magnetic-strip cards without disconnecting or disabling the bar code wand. These stationary scanners read tracks 1 and 2, or 2 and 3, of magnetically-encoded cards meeting the standards defined by ANSI x 4.13, ANSI x 4.16 1983, ISO 3554 and ISO 2894. -
Page 28: Laser And Ccd Scanners
Laser and CCD Scanners Worth Data laser and CCD scanners plug directly into WDR Reader SCANNER port. Laser scanners add these abilities to the WDR Reader: • Fast reading of difficult bar codes. • Reading bar codes from a distance •... - Page 29 5,479,000; 5,479,002; 5,479,441; 5,504,322; 5,528,621; 5,532,469; 5,543,610; 5,545,889; 5,552,592; 5,578,810; 5,589,680; 5,612,531 A stand is available for all of the Worth Data lasers and CCDs that allows hands free reading of bar codes. Just before placing the scanner in the stand, scan the bar code on the stand to set the laser into an automatic reading mode.
- Page 31 Four 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 WDR to keep reading until it gets two results that are exactly the same.
-
Page 32: Accumulate Mode
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. -
Page 33: Function/Control Key Support
Function/Control Key Support Function/Control Key Support with PortKey Using PortKey, the can emulate the special keys on the PC keyboard. PortKey expects the "extended key code" convention outlined in the BASIC manuals and most compiler manuals. For example, to transmit a F1 key from a WDR using PortKey to the PC’s keyboard, a null (ASCII 0) followed by a semicolon (ASCII 59) would be required. -
Page 34: Polling
Polling Polling is supported by PortKey for Windows. It allows cycling of files so that you can process the data of a just closed file while to continuing to collect data in the next generation file. PortKey is only $40 when purchased with a reader. To connect and configure your WDR readers for polling, do the following: 1. - Page 35 • If the reader has data to transmit, its LED returns to green, and it sends back its ID character, the bar code data, and its terminator character*. So when the computer transmits an a (and CR), reader a responds with a123456 (and its terminator character*), and its LED returns to green.
- Page 36 If you are transmitting over a long distance, you should use Polled with ACK/NAK protocol to decrease the chance of noise distorting the data. The following is a program to use ACK/NAK too: 10 DIM ID$(3) 20 NAK$=CHR$(21):ACK$=CHR$(6):TRUE=-1:FALSE=0 30 OPEN "COM1:9600,N,8,1,RS,DS,CD" AS #1 40 ID$(1)="a":ID$(2)="b":ID$(3)="c"...
- Page 37 example, suppose you are transmitting 123, followed by a CR(Hex 0D) to the host. The TriCoder ORs the three bytes to Hex 30 (ASCII 48); the high order nibble is transmitted as 33 and the low order nibble is transmitted as Hex 30. (The previous BASIC program illustrates this calculation and conversion.) The transmission format for polled WDR Readers is: [ID] [Preamble] [DATA] [Postamble] [Checksum Chs] [Terminator]...

Page 38: Troubleshooting
2. If the outlet is good, either the power adapter or the WDR Reader is not working properly -- call Worth Data. The reader doesn't beep when you try to read your bar codes: 1. - Page 39 2. Make sure you haven't enabled transmission of any start/stop characters, checksums or leading digits you don't want transmitted, and that Terminator Character is set to CR/LF, CR, HT or none as you desire. For UPC-E, select Compressed if you don't want it padded with zeros. Poor read rate: 1.
- Page 40 5. If you're using your own software to read the serial port, verify that the problem is not in your software by running a modem or communications program set to that serial port, and seeing if it gets any data on the screen when you read a bar code.

Page 41: Wdr Reader Cables And Pinouts
WDR Reader Cables and Pinouts There are several WDR Reader cable selection options for use with different types of computer systems and serial ports: • F34: A single null-modem cable with a female DB-25 connector, for direct attachment to a 25-pin serial port. •... - Page 42 Request To Send is tied high on both ports so the WDR Reader will always be able to transmit with systems using RTS/CTS protocol. Clear To Send, Data Set Ready and Data Terminal Ready are passed straight through between the host and terminal ports -- if your system uses any of these lines for handshaking, the handshaking will continue as before, with no interference from the reader.

Page 43: Opening The Wdr Case
Appendix A Opening the WDR Case Use the illustrations below as a guide for opening the WDR case, if you need to change or verify any jumper settings, or adjust the beeper volume. Turn your Reader upside-down, and unscrew its single Phillips screw. If you don't completely remove the screw, you can use it as a lever to pull up on the cover;... -
Page 44: Jumper & Switch Settings
Appendix B Jumper & Switch Settings Open the WDR Reader's case using the instructions in Appendix A. S1, the Input Device switch: “S1" is the switch on the WDR board near the scanner input ports. The W and L settings are a little misleading, because you can actually use the laser scanner with either setting. - Page 45 JP8, the DTS jumper: This jumper determines whether to force DTR high or not. By default, DTR is NOT high. To force DTR high, switch the jumper to DTR.
