Introduction The Worth Data Wireless Readers include the following products: 1) The LZ202-RF Laser Scanner and the LI102-RF Linear Imager CCD Scanner both have a range of 100 ft. and are 2-way products that provide a confirmation beep in the scanner to indicate the Base Station has received the data. For the US and Canada, the LZ202-RF and the LI102RF operate on four frequencies at 49MHz. For all of Europe, the LZ212RF and the LI112-RF operate on three frequencies at 40MHz.
Installation Components of Wireless Readers In the event the shipping box shows damage on arrival, please note the damage on the carrier's receipt log. The supposed contents of your Reader shipment is the following: 1. An R/F Base Station. 2. An antenna that attaches to the back BNC connector of the R/F Base Station/Decoder box. The 2-way RF Scanner Base Station uses a second antenna that mounts in the center of the Base Station. 3.
• If you are installing on a PC or Mac with traditional keyboard connectors, proceed to the next section describing keyboard wedge installation. • If you have a USB only PC or Mac, proceed to page 5. • If you have an R/F Serial Reader and wish to install to a dedicated serial port, turn to page 6. • If you have an R/F Serial Reader and wish to install between a terminal and a host computer in a multi-user system (such as UNIX) to turn to page 7.
Your computer, keyboard and reader should now be cabled as shown below: Turn on your computer: You will hear three beeps on the 1-way Base Stations, and the LED on the front will change from red to green, indicating that the Base Station is functioning correctly. The 2-way base will simply flash to green. If you have a PS/2 or a Mac, you will have to change the Computer Interface using the Wireless Setup Menu. Turn to page 9 to configure your RF Reader using the Wireless Setup Menu.
USB Installation on a PC or Mac: The USB port should have enough power to support the Base Station without needing the Worth Data external power supply. Therefore, the power supply is an optional charge feature. If you are connecting your Base Station to a portable computer (laptop or notebook), it is likely you will need to order our power supply. Most newer portables (all Macs and most PC-compatibles) may see the power draw by the USB device as too high and drop power to the USB port altogether.
Installing the R/F Reader with a dedicated serial port The Base Station can be directly attached to a spare serial port as shown below. 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 appear as though it had been typed at the keyboard. See page 28 for a simple BASIC program to read the serial port for testing purposes.
Installing the R/F Reader between a computer and terminal If you attach the Wireless Base between your computer and a terminal, as shown below, using Cable Selection F45-1, bar code data will be sent to the computer as if it had been typed on that terminal. Refer to page 8 for the details of the pin-outs for each connector on the cable. You will also need to change jumpers (JP2 on the RF Base) on the board inside the case from the “S” position to the “Y” position.

Configuring the Wireless Scanner for your computer and application Find the 8 1/2 x 11" laminated Wireless Reader Setup Menu sheet and look it over. This simple menu lets you easily configure the Radio/Freedom Reader to work with almost any computer system, and to tailor its bar code reading and data format characteristics. Be sure to read the scanning instructions on the next page. To read Reader Setup Menu bar codes and configure your reader, you must know the right way to scan bar codes.
Laser And Linear Imager CCD Scanning Instructions Using a laser scanner is basically as simple and intuitive as "point and shoot" at a distance of 0-24", depending on the density of the bar code. Our Linear Imager CCD scanners are also "point-and-shoot" and offer “laser-like” scan distances of 0 – 11 inches from the bar code. The LI101-RF Linear Imager CCD and the 1-way LZ200 RF Laser both beep only at the Base Station, so if the Base Station beeps, it got the data.
Don't forget to take the R/F Laser Scanner and the R/F Linear Imager CCD out of Setup Mode by scanning End Setup, otherwise the batteries will run down totally because the radio transmitter remains on. Using The Wireless Setup Menu 1. 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.
The next several pages will show you all of the various Wireless Reader options. Default settings are shown in bold in this manual and marked with an * on the Reader Setup Menu.

left to right reading of UPC codes, assuring that the supplement code is not missed. This setting also allows for reading of the UCC/EAN 128 Extended Coupon Code. The Extended Coupon Code consists of a UPC code with a NSC of 5 or and EAN code with a country code of 99 along with a C0de 128 supplemental code to the right. This setting allows you to read the Code 128 supplement with the UPC/EAN, providing the UPC has a NSC of 5 or the EAN code has a country code of 99.

with no trimming.) Consider the examples in the following table to understand how trimming works: Bar Code Data 123 12345678 12345678 12345 123456 Preamble XYZ ~3XYZ ~9 ~A ~5 Data Transmitted XYZ123 XYZ45678 12345678 12345 6 You can also trim selectively by bar code type. For example, you can trim 2 characters from Code 39 and a different amount from other bar code outputs. This is done by using the bar code ID character in conjunction with the tilde (~).
and min/max bar code data is also supported through Postamble specifications, (See Preamble above for complete details). Characters This setup option allows you to output ASCII characters different from the ones scanned. (Don't use this option to configure the Radio/Freedom Reader for your non-US keyboard -- instead, use the Keyboard Country option described below.
between a scanner and a base station make it possible for a group of associated scanners/base to ignore other groups of units with different IDs on the same frequency. This is not recommended, but where separation is the rule and overlap is the occasional exception, this grouping ID becomes practical.
4-second beam: Another option with problem reading conditions is to increase the length of the time the scanner attempts to read, from the default 2-second beam to a 4-second beam. To select the 4-second beam: Scan Start Setup Scan 2 of 5 Scan F to select the 4-second beam Scan End Setup To return to the default 2-second beam, scan E instead of F. Automobile VIN READING: There is special support for reading automobile Vehicle Identification Numbers, VIN, remotely from the computer.
"Double-scan checking": When reading a VIN, you will also want to disable double scan checking. The reader’s default is to not output or beep until it has two successive identical decodes. This is an acceptable safeguard with most codes, but with VIN numbers read through a windshield, you will have to deactivate double scan checking to get timely reads. Scan Start Setup Scan Code 39 Scan F to disable doubles scans. Scan End Setup To enable double scan checking, scan E instead of F.
Stop bits 1 Bit 2 Bits 0 1 Set the stop bits to the same setting your terminal is using, or you want to use with your serial port. Transmission mode Full Duplex Half Duplex 0 1 This applies to use of the "F45-1 Serial Y Cable" only. "Full Duplex" means that the R/F Reader will transmit data only through the HOST connector. With "Half Duplex", data is transmitted through the HOST and TERM connectors. Full Duplex should be used in almost all cases, but Half Duplex.
Please refer to Host Response Delay to determine if you need to compensate for slow host program response by slowing down the retry time when failing to get a response from the base station. Host Response Delay (This parameter only applies to serial 2-way Base Stations - B58/B59 with Host controlled acknowledge enabled.
distributed on the diskette enclosed with your serial reader. The program is for Windows only. If you are using the WDR Serial Test Program, follow these guidelines: • Make sure the serial parameters on your Base Station match those used by your computer. • Make sure you are connected to a valid serial port. If you still are having problems, see the Troubleshooting Section.
Radio Considerations Be sure you have a frequency matched Base Station and R/F Scanner. The color of the label on the underside of the R/F Base Station should match the color on the scanner antenna or ID label, ((black/black, yellow/yellow, purple/purple, red/red, etc).
2-Way Laser Operating Instructions Operational Details The two-way LZ202-RF Laser Scanner and LI102-RF Linear Imager CCD: 1. chirps on a "good read" or successful scan while turning off the scanner beam, and 2. beeps loudly when it gets the acknowledgement back from the Base Station that it has received the data. The yellow light on the back of the scanner indicates that it is transmitting.
Multiple 2-Way Base Stations on the Same Frequency. Although not recommended, you can have more than one two-way base station on the same frequency operating in a common area, but you must set each grouping of assigned scanner(s) with the ID of the Base Station. All other Base Stations with a common frequency must be turned off during the setup of another base and/or associated laser scanners. Otherwise, all base stations that can hear will be set to the same ID Character and its purpose will be defeated.
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. A small laminated barpad card is provided with each reader ordered to aid in entering variable quantities. It works with Code 39 only, and can't be used with a check digit.
Function/Control Key Support The RF Scanner 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. You can include these codes in other bar codes, or you can scan these “keystrokes” into your Preamble or Postamble in order to add them to every scan from your reader. You must have Full ASCII Code 39 enabled on your reader (this is the default setting).
Function keys F1 through F10, and numeric-pad keys (such as Left Arrow and Del), are encoded by a single control character as shown in the table above. Simply scan the correct bar code from the FULL ASCII MENU. For example, if the WDP reads the bar code SOH (ASCII 001 -- a control-A) from the FULL ASCII MENU, it will transmit an F1 key. Shift, Ctrl and Alt keys require three sequences: 1) The ON code generated when the Shift, Ctrl or Alt key is pressed.
Function keys F11 and F12 Function keys F11 and F12 require two bar codes to be scanned to make these functions keys. The F11 key is created by combining the Null and SOH. The F12 key is created by combining the Null and the STX. Windows Key The Windows key on a Windows keyboard is transmitted by scanning 4 bar codes - NULL and C for Windows On (pressing down) and NULL and D for Windows Off (releasing the key).
Troubleshooting All Models Troubleshooting The beam won’t stay on, or I just get a narrow beam when I pull the trigger, or The scanner won’t turn on when I pull the trigger and I get 3 beeps • All of the above problems are an indication that your BATTERIES ARE TOO LOW. With any of the above symptoms, change to known good batteries before assuming you have some other kind of problem. Also, make sure the batteries are inserted CORRECTLY – batteries won’t work if they are not inserted in the right direction.
The Decode Green Light on LZ200-RF One-Way Laser or LI101-RF Linear Imager CCD stays lit. • On One-Way units, the batteries will run down real fast too. This means that you are still in Setup Mode. Scan End Setup to turn the light out. The Orange light stays on the LZ202-RF 2-way RF Laser Scanner and LI102-RF Linear Imager Scanner. • You are in Setup Mode. Scan End Setup on the Wireless Setup Menu.
Serial Troubleshooting The reader beeps on reads, but nothing appears on your screen using PortKey OR nothing appears to your own software. • Recheck the installation instructions beginning on page 2 to make sure all cables are properly connected. • If you're trying to read Code 39 bar codes with leading spaces (such as the Barpad on page 28) and have enabled Accumulate Mode, those bar codes will not be transmitted to your computer until you read a bar code without a leading space.
My system locks up or I get Windows General Protection Faults when using my serial RF Reader on a PC running Windows. • This is an interference problem and occurs if you are using a serial extension cable over 80 feet long in combination with our F36 9-pin serial cable or F34 25-pin serial cable shipped before 9/15/01, or you have built your own cable (over 80 ft) and are not using our F36 or F34 cable.
Appendix A Opening the Base Case Use the illustrations below as a guide while removing the Base's circuit board from its case. Turn your Base unit 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, otherwise insert a fingernail, credit card edge or small screwdriver blade into the gap between the base and side of the case.
Appendix B Jumper Settings Your RF Base is shipped with P2 set as either keyboard or serial, depending on what you ordered. Why might you need/want to check or change jumper settings? • If you change from serial to keyboard wedge interface, you will need to change the P2 block from Serial to Keyboard (Kybd). You will need a serial cable too; the keyboard Y cable won't work with serial.
Appendix C 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 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.
Code 39 Advanced Features and Functions 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.
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 D 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. , , , and .
Appendix E Codabar Specifications 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. a12345b 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) varies from one to four units in width, totaling 11 units of width per character.
The Mod 10 Check digit is calculated the same as the Interleaved 2 of 5 example in Appendix G. It is the data length as well as the MOD 10 check digit that distinguishes the UCC Serial Shipping Container Code from other UCC /EAN 128 bar codes. UCC/EAN 128 is enabled by scanning the appropriate bar codes on the Wireless Reader Setup Menu.
Appendix G Interleaved 2 of 5 Code Interleaved 2 of 5 Code is a numeric-only, even-number-of-digits 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 position digits are encoded in the bars, even-number positions in the spaces.
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 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. UPC has very precise standards of code size, structure, and numbers to be used.
• The leading Number System Character, (the first number of the 11 digits to be entered) should conform to these UPC assignments: 0,6,7,8 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.

New York, New York 10036 Tel. 212.642.4900 www.ansi.org document ISO 2108:1992 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 Changing Batteries RF Laser and CCD Scanners These Scanners have 4 AA batteries located in the handle. On the bottom of the handle is a battery door that slides to the outside. Shake the batteries out and put new batteries in. Be careful to note the orientation of the batteries before placing them back in. The two batteries that go into the inside tube must have the nipples aimed at the scanner head.
Appendix K Firmware Upgrades Occasionally it will be necessary to get firmware fixes for problems discovered with the R/F Reader, especially in the early stages of each advance in development. This is accomplished by replacing the EPROM, a chip located on the board of the R/F Base Station's decoder box. To replace the EPROM, remove the cover to the Base Station box and the metal electromagnetic shield according to instructions in Appendix A.
