Appendix A. Barcode and Scan Options KDC200 uses a high performance laser scan engine, but it still needs proper setting for the best performance. Reading a barcode is a delicate and complicated process. Please do not try to change default settings unless you clearly understand the impact of the changes. SupportingBarcodes KDC200 supports the following barcode symbologies. It is important to select only the required symbologies to provide the best scan performance. z EAN13, EAN8, UPCA, UPCE z Bookland EAN, EAN13 with Addon, EAN8 with Addon, UPCA with Addon, UPCE with Addon z Interleave 2 of 5, ITF14 z Code128 z Codabar z EAN128 z Code39 z Code93 z Code35 Bookland EAN vs. EAN-13 “Bookland EAN” (that is, the group ISBN, ISSN, and ISMN) is supported by KDC200. This group of symbology is essentially a EAN-13 barcode with fixed prefix: 977 for ISSN, 978 for ISBN and 979 for ISMN. If EAN-13 and Bookland EAN are both enabled, then Bookland EAN takes precedence. Bookland EAN does not have any options. The Bookland EAN barcode does not contain any groupings – that is, there are no ‘-’ separators. Thus, the ISBN 957-630-239-0 will be transmitted as 9576302390. Addon Symbologies By default, the 2- or 5-digit add-on symbol with a UPCE, UPCA, EAN-8, and EAN-13 barcode is neither decoded nor transmitted. Its transmission for specific symbologies can be enabled by setting the appropriate
KDC200 User Manual 27 “withAddon” options. There are 4 options – one for each symbology: UPCEwithAddon, UPCAwithAddon, EAN8withAddon, and EAN13withAddon. The decoding of add-on symbols is typified by the following table, which explains the process for EAN-13 symbols: Value of flags Mode Behavior EAN13 EAN13withAddon Auto-discrimination If add-on symbol is present, then it is also decoded; otherwise only the EAN-13 symbol is decoded. true true With add-on Only EAN-13 barcodes with 2 or 5 add-on symbol are decoded. false true Without add-on The add-on symbol is ignored. true false The add-on symbol is appended to the EAN-13 barcode. The process is similar for UPCE, UPCA, and EAN-8 barcodes. Note that all the UPCE, UPCA, EAN-8, and EAN-13 formatting and conversion options are in effect. The following table should help explain the effect of various options for EAN-8 barcode 12345670 + 12: Barcode EAN8_as_EAN13 EAN8_ReturnCheckDigit EAN13_ReturnCheckDigit 1234567012 true 123456712 false tFalse N/A 00000123456712 false 000001234567012 true N/A true The add-on symbol neither contains check digit nor a terminating guard band. Every effort has been made to reduce the decoding error; however, it is likely to decode a partial scan of a 5-digit add-on symbol as a 2-digit add-on symbol. It is strongly recommended that the security level be set to minimum 2 while decoding add-on symbols. Since the decoder takes a conservative view on the add-on symbols, it is likely that the add-on symbol will be missed in the auto-discrimination mode. Auto-discrimination mode should then be avoided.
BarcodeOptions KDC200 supports the following barcode options z Transmission of start and stop characters z Reverse direction z Symbology conversion z Verification of optional check character z Transmission of check digit. TransmissionofStartandStopcharactersFor Codabar symbols user can choose not to transmit the start and stop symbols (the so called “NOTIS Editing”). By default, they are transmitted. Setting the field CodaBar_NoStartStopChars to true disables the transmission. ReverseDirectionThis option may be selected if direction oriented symbologies are selected such as code35. SymbologyconversionBy default the EAN-8, UPCE, and UPCA symbols are transmitted in their native format. It is possible to show them in a different format.

KDC200 User Manual 29 VerificationofOptional“CheckDigit”Code39 and Interleave 2 of 5 have an optional check digit, which, by default, is not verified. Their verification can be enabled by selecting the option VerifyCheckDigit to true or user can enable the verification for individual symbologies: Option Selected Verify Code39 check digit Verify I2of5 check digit VerifyCheckDigit Yes Yes Code39_VerifyCheckDigit Yes No effect I2of5_VerifyCheckDigit No effect Yes If the check digit verification fails then the barcode is not transmitted. Transmissionof“CheckDigit”By default, the check digit – optional or mandatory – is not transmitted. Its transmission can be enabled for all symbologies by enabling ReturnCheckDigit option. Is the check digit returned? Option Selected EAN-13 EAN-8 UPC-A UPC-E Code39 I2of5 ReturnCheckDigit Yes Yes Yes Yes Yes Yes EAN13_ReturnCheckDigit Yes No effect No effect No effect No effect No effect EAN8_ReturnCheckDigit No effect Yes No effect No effect No effect No effect UPCA_ReturnCheckDigit No effect No effect Yes No effect No effect No effect UPCE_ReturnCheckDigit No effect No effect No effect Yes No effect No effect Code39_ReturnCheckDigit No effect No effect No effect No effect Yes No effect I2of5_ReturnCheckDigit No effect No effect No effect No effect No effect Yes ResolutionofinconsistenciesThree types of inconsistencies could arise in the assignment of symbology options. The decoder has pre-defined strategies to resolve these inconsistencies: If UPCE_as_EAN13 is true, then UPCE_as_UPCA is ignored. If symbology conversion is selected but the target symbology is not enabled, then the decoder still outputs the symbol in the target symbology. For example, suppose UPC-E is enabled and UPCE_as_EAN13 is true but EAN-13 is disabled. All UPC-E symbols will be shown as EAN-13 and EAN-13 options (if specified) will be
applied. For the two symbologies that have optional check digits – Code39 and Interleave 2 of 5, the decoder will always transmit the check digit if the verification is disabled: Verify Check Digit Return Check Digit Description Disabled Enabled or Disabled Check digit is not verified but is transmitted Enabled Disabled Check digit is verified but is not transmitted Enabled Enabled Check digit is verified and is transmitted SystemInformation User can set up sleep time between 1 and 10 seconds. Please set up correct date and time before using the KDC200 for the first time, after replacing the battery or after resetting the device. User can check the memory and battery status in the system menu. The installed firmware version and device serial number can also be verified in the system menu. MiscellaneousBarcodeInformation How tall should a linear barcode symbol be? Industry standards suggest a height of either 6.5mm or 15% of the symbol length, whichever is greater. Symbols of lesser than recommended heights may cause recognition problems. Should I use check characters? Yes, we recommend the use of check-characters in barcodes. Operating without check-characters is not safe and will lead to errors that are costly to correct. Using check-characters positively effects data integrity especially when character density is at the limits and/or image quality is not at it's best. Prevents Interleave 2 of 5 Partial Reading A partial scan of an Interleave 2 of 5 symbol may decode and cause incorrect data to be read. To prevent partial scans on long symbols, user should include bearer bars. These are bars that run along the top and bottom edges of the symbol in the scanning direction. If a partial scan of the symbol occurs, the scanning beam will hit the bearer bar and will not decode. The bearer bar must touch the top and bottom of all the bars and must be at least 3X wide. Another solution for the short scanning problem is to fix all Interleave 2 of 5 symbols to a set number of digits. Zeros can be used to pad the data to the set number of digits. The application program would then be set to only
accept scans of the correct number of digits. Finally, a check digit may be used. The Interleave 2 of 5 symbology has an optional check character which uses a weighted Modulo 10 scheme. The check character is the last character in the symbol and should be checked by the decoder and then transmitted with the data. Since Interleave 2 of 5 must always have an even number of digits, the leftmost character may need to be a zero when the check character is added. The standard check digit is calculated by assigning alternating 3,1,3,1… weights to respective data digits. These weights are then multiplied by their respective data digits and the products are summed. The check digit is the digit needed to be added to the sum to make it an even multiple of 10. An example would be if the sum of the products was 37, the check digit would be 3. How many barcodes can we store? The number of barcodes that can be stored in these bytes depends upon the size of the barcodes Example: If only UPCA barcodes are scanned and the check digit is not transmitted, then each barcode takes up 11 (barcode data) + 2 (total bytes) + 2 (length and type) + 4 (time stamp) = 19 bytes. The maximum number of UPCA barcodes that can be saved is 204,800/19 =10,778. However, the maximum number of barcodes that can be stored is 10,240. Therefore, the KDC200 can store 10,240 UPCA barcodes. If different length barcodes are mixed, then a user cannot compute a priori the maximum number of barcodes that can be stored. What happens when the data buffer is full? When the buffer is full, KDC200 displays buffer full message and ignores the command to scan barcodes. User should clear the buffer to continue the data collection.
