2 / 15 page  4-48 tions for a number of stationary scanning applications found in automated systems. The scan rate for moving beam applications should be similar to the scan rates for hand held laser scanners (35 to 45 scans per second). The scan speed for fixed beam applications should be similar to the scan speeds typical of wands and slot readers. For moving beam applications, it is necessary for the scanner to utilize the three laser control lines. The HBCR-2210 series decodes the most popular bar code sym- bologies now in use in applica- tions in the industrial, retail, government and medical markets: • Code 39 (Standard or Extended) • Interleaved 2 of 5 • UPC A, E • EAN/JAN 8, 13 • Codabar • Code 128 • Code 11 • MSI Code When more than one symbology is enabled, the bar code being scanned will automatically be recognized and decoded, except for Standard versus Extended Code 39, which are mutually exclusive. Bi-directional scanning is allowed for all bar codes except UPC/EAN/JAN with sup- plemental digits, which must be scanned with the supplemental digits last. The I/O for the decode IC is full duplex, 7 bit ASCII. Both serial and parallel interfacing are available. The serial interface can be converted to an RS232C interface or connected directly to another microprocessor for data processing. The parallel interface can be connected to a 74HC646 octal bus transceiver chip (or an equivalent part). Feedback to the operator is accomplished by signals for an LED and a beeper. In addition, there are many programmable functions that cover such items as code selection, good read beep tone, Header and Trailer buffers, laser scanning control, beeper tone, etc. See Table 2 for a complete list. Performance Features Bar Codes Supported Code 39 is an alphanumeric code, while 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 config- ured to verify this character prior to data transmission. Interleaved 2 of 5 code, a com- pact 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 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 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. When supplemental encodations are enabled, the bar code symbols must be read in a direction which 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 decode IC can be configured to transmit or suppress the Codabar start/stop characters. Code 128, a full ASCII symbology, can be scanned bi- directionally with message lengths of up to 32 characters. Code 11 is a numeric, high density code with one special character, the hyphen (-). Verification of one or two check characters must be enabled, and the check character(s) are always transmitted. This code can be scanned bi-directionally. MSI Code is a numeric, continu- ous code, with message lengths up to 32 characters. The check digit, a modulo 10 checksum, is always verified and transmitted. This code can be scanned bi- directionally. Scanner Input The HBCR-2210 decode IC is designed to accept data from hand held digital scanners or slot readers with the following logic state: black = high, white = low. The same decode IC also accepts |
