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 LI102- RF operate on four frequencies at 49MHz. For all of Europe, the LZ212- RF and the LI112-RF operate on three frequencies at 40MHz. -

DON'T USE ANY OTHER POWER SUPPLIES OR YOU WILL BURN UP THE BASE STATION. - Page 7 USB port for keyboard attachment, proceed to page 5. 99% of computer keyboard ports have enough power to support the Base Station without needing the Worth Data external power supply. Therefore, the power supply is an optional extra charge feature.
- Page 8 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.
- Page 9 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.
- Page 10 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.

Page 13: Configuring The Wireless Scanner
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. - Page 14 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 –...
- Page 15 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 To configure your reader using the Reader Setup Menu, you must first scan the Start Setup code at the top left corner.

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.

For example: Suppose you want the Radio/Freedom Reader to output a hex... - Page 24 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.

"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. -

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.

2-Way Laser Operating Instructions Operational Details The two-way LZ202-RF Laser Scanner and LI102-RF Linear Imager CCD: chirps on a "good read" or successful scan while turning off the scanner beam, and beeps loudly when it gets the acknowledgement back from the Base Station that it has received the data. - Page 32 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.

Page 33: 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 34: Function/Control Key Support
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”... - Page 35 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.

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. -

Page 43: Specifications For Code 39
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. -

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. - Page 57 The MSI Mod 11 check digit is calculated as follows: The example bar code data is: 943457842 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).

Page 59: Firmware Upgrades
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. -
