3–12 Configuring Your Scanner Convert UPC-E to UPC-A When enabled, this option converts UPC-E (zero suppressed) decoded data to a UPC-A format before sending the data. After conversion, output data will be affected by UPC-A programming selections such as preamble and check digit settings. EAN Zero Extend When enabled, five leading zeros are added to decoded EAN 8 symbol data. The five zeros make the EAN 8 symbols compatible with the EAN 13 format.
Configuring Your Scanner 3–13 MSI Plessey check Digit When enabled, one or two digits at the end of the bar code that checks the integrity of that data. Code 39 Buffering (Scan and Store) When enabled, the scanner stores all Code 39 symbol data that has a leading space as the first character. As Code 39 labels are scanned for buffering, the scanner provides a high/low beep to indicate that the data is stored in the buffer. The leading space is not stored in the buffer.
3–14 Configuring Your Scanner Beep After Good Decode When enabled, the scanner will beep during normal operation. The beeper operates during parameter menu scanning and indicates error conditions. It is recommended that you leave this option enabled. UPC / EAN Security Level There are four levels of decode security. There is an inverse relationship between security and the ability to decode codes of varying quality. Increasing levels of security are provided for decreasing levels of bar code quality.
Configuring Your Scanner 3–15 UPC-A / UPC-E Preambles The UPC preamble consists of the system character and country code. The system character is the the first character on the left side of the symbol. The country code for UPC is always 0. Select whether these characters are sent with the bar code data: • system character only • country code and system character • no preamble Note: There are separate preamble programming codes for both UPC-A and UPC-E symbols.
3–16 Configuring Your Scanner Data Transmission Formats You can set whether or not prefix or suffix data is added to the decoded symbol data. You have four options: • Only bar code data is sent. This is the default setting. • Bar code data is sent, then the suffix data. • Prefix data is sent, then bar code data followed by the suffix data. • Prefix data is sent then the bar code data.
Configuring Your Scanner 3–17 Parity Checks to ensure that the correct number of bits are contained in the coded character. You can set the parity of each ASCII coded character that is transmitted. Make sure the parity matches the requirements of the host. The selections are: • Odd • Even • Mark (parity bit always set to 1) • Space (parity bit always set to 0) • None (Default) Check Parity When enabled, the scanner checks the received characters for parity.
3–18 Configuring Your Scanner 2. If the CTS line is not active, the base/charger unit will assert the Request to Send (RTS) line and waits one second for the host to assert the CTS line. When the host asserts the CTS line, the base/charger unit transmits the data. During the transmission of data, the CTS line should be asserted. 3. After the transmission is completed, the base/charger unit will negate the RTS 10 msec after sending the last character. 4. The host device should then negate CTS.
Configuring Your Scanner 3–19 ENQ ONLY requires that the base/charger unit receive an an enquire character (ENQ) from the host before sending data. With ENQ enabled, the base/charger unit must receive an ENQ from the host within a two second period after the last scan or a transmission error occurs. The scanner will provide four short beeps to indicate the error; the base/charger unit is ready to send again. ACK/NAK with ENQ combines both ACK/NAK and ENQ options.
3–20 Configuring Your Scanner Intercharacter Delay When enabled, the host system has time to service its receiver and perform other tasks between characters. You can choose up to 99 msec delay between transmission of characters. The default parameter is set to zero. Transmit Code ID Characters The code ID identifies a scanned bar code symbol’s code type. If enabled, the code ID is sent after the prefix and before the bar code data.
Configuring Your Scanner 3–21 International Keyboard Emulation When enabled, this parameter allows you to send the code from the type of keyboard that you have. This parameter will allow you to select a national keyboard type. This parameter is supported by IBM AT/XT/PS2 computers only. The default parameter is disabled.

Appendix C Advanced Data Formatting This appendix describes how to use the Advanced Data Format (ADF) feature. Included are sections on: • ADF overview • rules hierarchy • default rule • listening for audible responses • using ADF in a sorting application ADF Overview ADF allows you to customize input before it is transmitted to your host device. For example, instead of having a direct read of a bar code, you can now attach a message to it.
C–2 Advanced Data Formatting Input Source Criteria Code Type Code Length Rules Send Data Send Keystroke Actions Setup Pause Send Preset Value Criteria Criteria are used to select the bar codes that the Actions act upon. Criteria are composed of an Input Source, Code Type, and Code Length. Input Source is the source affected by using using ADF and is selected prior to creating any ADF rules. Code Type is the symbology selected.
Advanced Data Formatting C–3 Actions Actions allow you to select how to format data for transmission. Actions are composed of Send Data, Send Keystroke, Setup Pause, and Send Preset Value. Send Data allows you to send all the data that follows, send all the data up to a specific character selected from the alphanumeric keyboard bar code, or send the next number of characters (1 to 254) selected from the alphanumeric keyboard.
C–4 Advanced Data Formatting Listening for an ADF Audible Response When scanning an ADF bar code symbol, you hear beeps from the scanner. Refer to the following tables to determine the meaning of the beeps. Beep Indicating Normal Operation The duration of the following tones are short. This Response Indicates 2 Beeps (high–low tone) Entry of a number is expected. Enter another digit. Add leading zeros to the front if needed. 2 Beeps (low–low tone) Entry of a alphabetic character is expected.
Advanced Data Formatting C–5 Beep Indicating Error The duration of the following tones are long. This Response Indicates 4 Beeps (low–high–low–high tone) Out of Rule memory. Erase some of the existing Rules, then try and save Rule again. 3 Beeps (low–high–low tone) Cancel rule entry. Rule entry mode exited because of an error or you were asked to exit Rule entry. 2 Beeps (low–high tone) The wrong bar code was scanned. Re–enter the Criteria or Action.
C–6 Advanced Data Formatting ADF Sorting Application Example In this example, ADF is used to expand the message seen by assembly workers packing and sorting boxes on a conveyor line. Without ADF, the message reads: PURPLE 123 With ADF, the message reads: Place item in PURPLE box Place box on conveyor # 123 To expand the message by scanning the appropriate bar codes located in the Hand-Held Cordless Bar Code Scanners Programming Guide (Publication No. 2755-6.6), you need to: 1. Select the Input Source.
Glossary A ASCII American Standard Code for Information Interchange. A 7-bit-plus-parity code representing 128 letters, numerals, punctuation marks, and control characters. ASCII is a standard data transmission code in the U.S. B Bit Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of data. The pattern of 0 and 1 values within the byte determines its meaning.
G–2 Glossary Check Digit A digit used to verify a correct symbol decode. The scanner inserts the decoded data into an arithmetic formula and checks that the resulting number matches the encoded check digit. Check digits are required for UPC but are optional for other symbologies. Using check digits decreases the chance of substitution errors when an error is decoded. Codabar A discrete self-checking code with a character set consisting of digits 0 to 9 and six additional characters: (- $ : / , +).
Glossary G–3 E EAN European Article Number. This European/International version of the UPC provides its own coding format and symbology standards. Element dimensions are specified metrically. EAN is used primarily in retail. H Host Computer A computer that serves other terminals in a network, providing such services as computation, database access, supervisory programs, and network control.
G–4 Glossary L Laser An acronym for Light Amplification by Stimulated Emission of Radiation. The laser is an intense light source. Light from a laser is all the same frequency, unlike the output of an incandescent bulb. Laser light is typically coherent and has a high energy density. Laser Diode A gallium-arsenide semiconductor type of laser connected to a power source to generate a laser beam. This laser type is a compact source of coherent light.
Glossary G–5 Symbology The structural rules and conventions for representing data within a particular bar code type (e.g. UPC/EAN, Code 39). U UPC Universal Product Code. A relatively complex numeric symbology. Each character consists of two bars and two spaces, each of which can be one of four widths. This is the standard symbology for retail food packages in the United States. Publication 2755-6.
