| Programmable Bar Code Decode ICs Technical Data HBCR-2010 HBCR-2011 Features * Ideal for Hand Scanning and Many Automated Scanning Applications * Supports Code 39, UPC / EAN / JAN, Interleaved 2 of 5, Codabar and Code 128 Standard Bar Code Symbologies * Automatic Code Recognition * Serial Port Interface * Full Duplex ASCII Interface * Extensive Configuration Control * Low Current CMOS Technology * 40 Pin DIP and 44 Pin PLCC Packages * Audio and Visual Feedback Control * Single +5 Volt Supply Description Agilent's Bar Code Decoder ICs offer flexible bar code decoding capability that is designed to give OEMs the ability to address a large number of industry segments and applications. Flexibility is made possible through sophisticated firmware, which allows the ICs to accept data from a wide variety of scanners and to automatically recognize and decode the most popular bar code symbologies. User implementation of decoder ICs is easy since it requires only a few supporting chips and components and provides a standard I/O interface. Manufacturers of data collection terminals, point of sale terminals, keyboards, weighing scales, and other data collection and material handling equipment are finding a growing demand for bar code reading capability in their products. The HBCR-2010 series decoder ICs make it easy to add this capability without the need to invest in the development of bar code decoding software. The bar code decoder ICs are compatible with most hand held scanners. The HBCR-2010 series is compatible with fixed beam non-contact scanners, digital wands, digital slot readers and Symbol Technologies moving beam laser scanners. The HBCR-2010 decoder ICs are excellent decoding solutions for a number of the stationary scanning applications found in automated systems. The scan rates for moving beam applications should be similar to the scan rates for hand held laser scanners (35 to 45 scans per second), and the scan speeds for fixed beam applications should be similar to the scan speeds typical of wands and slot readers. For moving beam applications, it is also necessary for the scanner to utilize the three laser scanner control lines. 2 The decoder ICs decode the bar code symbologies now in use for most applications in the industrial, retail, government, and medical market. The ICs support Code 39 (Standard or Extended), Interleaved 2 of 5, the UPC/EAN/ JAN Codes, Codabar and Code 128. Whenever more than one symbology is enabled, the bar code being scanned will automatically be recognized and decoded, except for Standard and Extended Code 39 which are mutually exclusive. Bi-directional scanning is allowed for all bar codes except UPC/EAN/JAN with supplemental digits, which must be scanned with the supplemental digits last. The I/O for the decoder ICs is full duplex, 7 bit ASCII. A serial port is available. The serial interface can be converted to an RS232C interface or connected directly to another microprocessor for data processing. Feedback to the operator is accomplished by signals for an LED and a beeper. In addition, there are programmable functions covering items such as code selection and beeper tone. The ICs are CMOS, in either a 40 pin DIP package or a 44 pin PLCC package. All ICs require a dedicated external data memory, 2K or 8K x 8 bit static RAM (only 1K is needed) and address latch chip (a 74LS373 or equivalent). The crystal frequency is 11.059 MHz. Performance Features Bar Codes Supported The decoder IC is capable of reading popular bar code symbologies : Code 39 (Standard or Extended), Interleaved 2 of 5, UPC/EAN/JAN, Codabar (NW7 Code) and Code 128. Code 39 is an alphanumeric code, and Extended Code 39 encodes the full 128 ASCII character set by pairing Code 39 characters. Both can be read bi-directionally with message lengths of up to 32 characters. An optional checksum character can be used with these codes, and the ICs can be configured to verify this character prior to data transmission. Note that enabling Extended Code 39 will disable Code 39 since they are mutually exclusive. Interleaved 2 of 5 code, a compact numeric only bar code, can also be read bi-directionally with message lengths from 4 to 32 characters. To enhance data accuracy, optional checksum character verification and/or message length checking can be enabled. The following versions of the UPC, EAN and JAN bar codes can be read bi-directionally: UPC-A, UPC-E, EAN-8, EAN-13, JAN-8, and JAN-13. All versions can be enabled simultaneously or decoding can be restricted to only the UPC codes. UPC, EAN, and JAN codes printed with complementary two digit or five digit supplemental encodations can be read in two different ways. If the codes are enabled without the supplemental encodations, then only the main part of symbols printed with supplemental encodations will be read. If the reading of supplemental encodations is enabled, then only symbols with these supplements will be read. Whenever supplemental encodations are enabled, the bar code symbols must be read in the direction that results in the supplements being scanned last. Codabar, a numeric only bar code with special characters, can be read bi-directionally for message lengths up to 32 characters. The start and stop characters are normally transmitted, but can be suppressed by a software command. Code 128, a full ASCII bar code, can also be scanned bidirectionally with message lengths of up to 32 characters. Scanner Input The decoder ICs are designed to accept data from hand held digital scanners or slot readers with the following logic state: black = high, white = low. They also accept data from hand held laser scanners with the opposite logic states: black = low, white = high. The scanner type pin (SCT) must be driven prior to power up or hard reset to identify the type of scanner attached to it. 3 The automatic laser shutoff feature delay time is adjustable by software commands. Applications which require extreme accuracy may need the redundancy check feature. If either motor failure sensing or calculation of the ratio of laser on time to off time is needed for an application, it must be supported with external circuitry. Scanner input can be disabled by software command. This allows an application program to control when an operator can enter data, preventing inadvertent data entry. It also allows the program to verify each scan before enabling subsequent scans. There is also a single read mode which allows the application program to stop bar code data entry until a "Next Read" command is received, allowing the host computer to process data transmissions before enabling subsequent reads. Data Communications The serial port supports a wide range of baud rates, parities, stop bits, and terminator characters, as described in Summary of Features and Configuration Control table. Software control of data transmission is accomplished with an Xon/Xoff (DC1/DC3) handshake. There is also an RTS/CTS hardware handshake. Feedback Features Both audio and visual feedbacks are possible with the decoder ICs. In both cases, the outputs from the ICs must be buffered before driving the actual feedback mechanism. An LED or beeper connected to the decoder ICs can be controlled directly by the IC, with signals generated by successful decodes or can be controlled by the host system. Power Requirements The decoder IC operates from a +5 volt DC power supply. The maximum current draw is 19mA. The maximum power supply ripple voltage should be less than 100 mV, peak-to-peak. Configuration Control Configuration of the decoder IC is determined by hardwire connections and/or through software commands. Hardwire selection is limited to key operating parameters. A greater range of configuration control is available via software commands. A summary of the decoder IC features and configuration control is presented in Summary of Features and Configuration Control table. Handling Precautions The decoder ICs are extremely sensitive to electrostatic discharge (ESD). It is important that proper anti-static procedures be observed when handling the ICs. The package should not be opened except in a static free environment. Manuals The decode IC Users Manual covers the following topics: * Data output formats * I/O interfaces * Laser input timing diagrams * Escape sequence syntax and functionality * Example schematics * All configurable options * Bar code menus * Scanner positioning and tilt * Sample bar code symbols * Appendices describing bar code symbologies.

PLCC Drying Whenever Vapor Phase or Infrared Reflow technologies are used to mount the PLCC packages, there is a possibility that previously absorbed moisture, heated very rapidly to the reflow temperatures, may cause the package to crack from internal stress. There is a reliability concern that moisture may then enter the package over a period of time, and metal corrosion may take place, degrading the IC performance. To reduce the amount of absorbed moisture and prevent cracking, all of the PLCC ICs should undergo one of the following baking cycles. The parts MUST then be mounted within 48 hours. If the parts are not mounted within 48 hours, they MUST be rebaked. The total number of baking cycles must not exceed two (2). If the ICs are baked more than twice. Agilent cannot guarantee the performance and reliability of the parts. Neither bake cycle can be performed in the standard shipping tubes. The ICs must be baked in an ESD safe, mechanically stable container, such as an aluminum tube or pan. Cycle A B Temperature 125C 60C Time 24 Hours 96 Hours Notes 1 Note: 1. Cycle B must be done in an atmosphere of < 5 % relative humidity air or nitrogen. 10 Contact Scanner Input Circuit VCC 1 SCANNER CONNECTOR 2 3 4 5 1 K SCANNER INPUT (R)TRANZORBS P6KE 7.5 C SHIELD Figure 6.
