amakuru

Nubwo buri musomyi asoma kode muburyo butandukanye, igisubizo cyanyuma nuguhindura amakuru mubimenyetso bya digitale hanyuma mubisobanuro bishobora gusomwa cyangwa bigahuzwa na mudasobwa. Porogaramu ya decoding mu gikoresho cyihariye irarangiye, barcode iramenyekana kandi itandukanijwe na decoder, hanyuma igashyirwa kuri mudasobwa yakiriye.

Gukuramo amakuru bigomba guhuzwa cyangwa guhuzwa na nyiricyubahiro, kandi buri gice kigomba kugira ibice bibiri bitandukanye: kimwe ni urwego rwumubiri (ibyuma), naho ubundi ni urwego rwumvikana, rwerekeza kuri protocole y'itumanaho. Uburyo busanzwe bwa interineti ni: icyambu cya clavier, icyambu gikurikirana cyangwa guhuza bitaziguye. Iyo ukoresheje uburyo bwa clavier ya interineti, amakuru yikimenyetso cya barcode yoherejwe numusomyi afatwa na PC cyangwa terminal ko ari amakuru yoherejwe na clavier yayo, kandi mugihe kimwe, clavier zabo nazo zishobora gukora imirimo yose. Mugihe ukoresheje imiyoboro ya clavier ihuza gahoro cyane, cyangwa ubundi buryo bwa interineti ntibuboneka, tuzakoresha uburyo bwo guhuza ibyambu. Hano hari ibisobanuro bibiri byihuza ritaziguye hano. Imwe isobanura ko umusomyi asohora amakuru kuri nyirarureshwa nta bikoresho byongera decoding, naho ubundi bivuze ko data decode ihujwe neza na host idakoresheje clavier. Amagambo amwe akunze gukoreshwa Dual Interface: Bisobanura ko umusomyi ashobora guhuza byimazeyo ibikoresho bibiri bitandukanye, hanyuma agahita agena kandi akavugana na buri terminal, urugero: CCD ikoreshwa muguhuza itumanaho rya POS ya IBM kumanywa, nijoro. Bizahuza amakuru yikurikiranwa kubintu byabitswe, kandi ikoreshe ibyubatswe byombi byubushobozi kugirango inzibacyuho hagati yibikoresho byombi byoroshye. Flash yibuka (Flash Memory): Flash yibuka ni chip ishobora kubika amakuru idafite amashanyarazi, kandi irashobora kurangiza kwandika amakuru mukanya. Ibyinshi mubicuruzwa bya Welch Allyn bikoresha flash memory kugirango bisimbuze PROM yumwimerere, bigatuma ibicuruzwa bizamuka cyane. HHLC. Porotokole yubu buryo bwitumanaho, izwi cyane nka laser simulation, ikoreshwa muguhuza CCD cyangwa umusomyi wa laser hamwe na Shyira decoder. RS-232. RS-232 mubisanzwe ikoresha 25-pin ya DB-25 cyangwa 9-pin ya DB- 9. Intera y'itumanaho ya RS-232 muri rusange iri muri 15.24m. Niba umugozi mwiza ukoreshejwe, intera yitumanaho irashobora kuramba.
