Introduction The Worth Data RF Laser has the following features: 1) The LZ400-RF Laser Scanner for the USA and Canada. This laser has a range of up to 500 feet (open area) and has collision detect and retry logic built within. The LZ400-RF Laser communicates with the B78 Base Station. The Base Station communicates with a host PC through the USB port or a RS-232 Serial Port. Up to ten LZ-400 RF Lasers can communicate with one B78 Base Station.
Installation Components of RF Laser 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 B78 RF Base Station with 1-10 LZ400-RF Lasers. 2. A Worth Data regulated 5V power supply with each LZ400-RF Laser Scanner ordered, and if you ordered a serial cable with the B78 Base Station, you will receive a power supply for the Base also.
USB Installation USB attachment will not work with the Worth Data F10 5v power supply for the B78 Base Station. If for some reason your USB port or hub does not have enough power to operate the Base Station correctly, you will need a powered USB Hub. The Base Station will power up with 3 more flashes than the channel setting; i.e. if it is set on Channel 0, it will flash green three times. If the Channel were set to 7, it would flash green 10 times.
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. This configuration requires the Worth Data F10 5v power supply for powering the Base Station. Upon power-up, the Base Station LED will flash with 3 more flashes than the channel setting; i.e. if it is set on Channel 0, it will flash green three times. If the Channel were set to 7, it would flash green 10 times.
Installing the R/F Reader between a computer and terminal If you attach the s 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 RF Laser Reader for your computer and application The RF Laser Setup Menu is located in Appendix J of this manual. This simple menu lets you easily configure the RF Laser 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 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. Basically, the 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. You'll need to hold the scanner further away to produce a wider beam for large bar codes, and closer for bar codes with bars very close together.
For example, to read this "5" bar code on the Setup Menu, you would need to cover any adjacent bar codes with paper or a finger first, as shown. Don't forget to take the R/F Laser Scanner of Setup Mode by scanning End Setup, otherwise the batteries will run down totally because the radio transmitter remains on. Using The RF Laser Setup Menu 1. To configure your reader using the Reader Setup Menu found in Appendix J of this manual. You must first scan the Start Setup code at the top left corner.
RF Laser Setup Parameters Channel Default Channel 0 • The default Channel is always shipped as 0. There are 10 channels in the USA and Canada. The Channel for the RF Laser Reader is set by scanning the Setup Menu. • All Lasers and associated Base Station must be set to the same channel. If you have more than one RF Laser per Base Station, you must set a unique ID in each RF Laser. (See SET ID.) • The Laser channel must match the channel on the Base station.
If you've enabled the check digit, enabling Check Digit transmission causes the reader to transmit it to your computer along with the bar code data. "Caps Lock ON" means that for all codes lower case letters read as data will be transmitted as upper case, and upper case as lower. Numbers, punctuation & control characters are not affected. This applies to Code 128 and Code 93 also. "Caps Lock OFF" means that letters will be transmitted exactly as read.
UPC-E can be used in either normal UPC-E format (implicit NSC of 0) or UPC-E1 format (NSC of 1). UPC-E1 is enabled by scanning 2 of 5 Code and 8 (9 disables UPC-E1). It is very easy to partially read EAN-13 as UPC-E1, so don't enable UPC-E1 if reading EAN-13. If you wish to transmit UPC-A data in EAN-13 format, (an added leading 0 for the USA's country code), scan Terminator Character and F. Scanning E, the default, sets UPC back to no country code transmitted.

2 of 5 Data Length 2 of 5 Code is so susceptible to interpreting partial scans as valid reads that the RF Laser uses fixed-length data as a safeguard. To choose a data length, scan it as a two-digit number using the Barpad Table. For example, to select 8-digit data length, you would scan a 0 and then an 8. Because Interleaved 2 of 5 is required to be an even number of digits in length, you must use an even number.
The default is no preamble. To select a preamble, scan up to 15 characters from the "FULL ASCII MENU" on the back of the RF Laser Setup Menu, and then scan SET when you're done. To return to the no preamble setting, scan Clear here instead of scanning SET or any characters from the FULL ASCII MENU. You can trim 1-15 leading characters from bar code codes by scanning a ~ (tilde -- ASCII 126) followed by a single digit, 1 through F, as part of the Preamble.

Selective trimming 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.
the Setup Mode when performing the link test. This code is the same as the "Clear Buffer" code on the Barpad Menu. Reset Once you are in the Setup Mode, don't scan Reset unless you're sure you want to restore the RF Laser to its default settings (as described on page 7), erasing all changes you've made. DIFFICULT CODE SETUP OPTIONS Aiming Laser Dot: Sometimes it is difficult to see the laser beam and know you are on the bar code, especially if you are attempting to read outdoors in direct sunlight.
Scan Start Setup Scan Terminator Scan B to select "delayed transmission" Scan End Setup To disable "delayed transmission", repeat the above substituting A for B. "Difficult Code 39 Reading": This feature facilitates reading of he VIN number on automobiles, which is often a difficult-to-read bar code, especially reading through a windshield. VIN numbers are long, often weathered, often dirty, and challenging to read.
RF Base Station Parameters The following parameters apply only to a base station attached serially. Baud rate 300 600 1200 2400 4800 9600 19,200 0 1 2 3 4 5 6 Data bits 7 Bits 8 Bits 0 1 Set the data bits ("word length") to the same setting your terminal is using, or you want to use with your serial port. Parity None Even Odd 0 1 2 Set parity to the same setting your terminal is using, or the one you want to use with your serial port.
If you want the host computer program to analyze the data and to send back different beep patterns to the laser scanner, enable Host Controlled Acknowledge. With this parameter enabled, the data is passed to the computer and no acknowledgement is sent to the scanner until the host computer replies to the base station with one of three possible ASCII codes: ACK (ASCII 06), BEL (ASCII 07), DC2 (ASCII 18).

Radio Considerations Operating Instructions Operational Details The RF Laser: 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. You will see up to four transmission attempts before the unit goes to sleep and waits for you to pull the trigger again.
Accumulate Mode Accumulate Mode is an option (which can be enabled or disabled using the RF Laser 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.
Function/Control Key Support The RF Laser 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).
Simply scan the correct bar code(s) 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. 2) The other key to be used in conjunction with the Shift, Ctrl or Alt key. 3) OFF code generated when the Shift, Ctrl or Alt key is released.
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, recharge the battery in the RF Laser before assuming you have some other kind of problem. The reader won't beep when reading bar codes • Recheck all the connections. Get close to the Base Station.
USB Trouble Shooting The Base Station's light flashes in Red cycles when the USB cable is connected. • The Base Station cannot enumerate. The driver is probably not installed correctly. Occasionally the user will be unaware that he aborted his driver installation. Once the process has started, it should finish successfully. If it doesn’t, you will not see any data on the screen when scanning. To resolve a driver installation problem follow the applicable instructions below: Windows® XP & Vista®: 1. 2. 3.
Windows® 2000: 1. 2. 3. 4. 5. 6. Log on as Administrator and open the “Administrative Tools” folder in your Control Panel. Run the “Computer Management” utility. Select the “Tree” tab on the left panel Find the “Device Manager” entry under “System Tools” and click on it. The right panel will display current devices. Problem devices will be identified with an “!” icon.
Data characters are garbled or missing. • Make sure you've set the reader to the same baud rate, parity, data bits and stop bits as your serial port. • If Code 39 bar codes are transmitting in the wrong case (upper and lower transposed), set Caps Lock Off on the Setup Menu. • If you're getting occasional extraneous characters, try cutting the jumper between pins 8/20 in the serial Y-Cable's DB25 connectors. See page 6.
Appendix A Changing Jumpers and Channels You may want to change the channel on the Base Station or you may want to set the unit to use a Serial Y Cable. To do so, open up the 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.
Serial Users, if you are going to use the Serial Y Cable (F45-1), you will need to change the JP2 (Jumper 2) from S to Y. This permits Half Duplex transmissions and interface between a host and terminal. Special Laser Pairing Mode: Multiple Laser/Base Pairs can be used in the same location by using our special Pairing feature.
Appendix B Recharging the Batteries The LZ400-RF Laser has a rechargeable lithium ion battery built-in. When not in use, the RF Laser should be plugged into the supplied, regulated Worth Data 5V power adapter (DO NOT USE ANY Supply Except Worth Data), so that it will always be recharged. The built-in recharger is a smart charger, so you can't overcharge the battery and ruin it. A full charge takes about 3 hours.
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 RF Laser 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 GS1 US. (Do not use 0 as the leading number for instore 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.
