Dab tsi yog Qhov Kev Sib Tw Ntawm Cov Barcode Scanner

Muaj plaub hom interface rau barcode scanners:

SCSI (Cov Txheeb Ze Me Nyuam Yaus Qauv Me)

Tus naj npawb ntawm cov khoom sib txuas ntawm lub interface no yog 8. Feem ntau, qhov ntau tshaj ntawm qhov sib kis ceev yog 40M / S, uas yog nrawm. Feem ntau, cov khoom siv hluav taws xob nrawm txuas nrog. Kev teeb tsa ntawm SCSI khoom siv yog qhov nyuaj ntxiv. Feem ntau, SCSI daim npav ntxiv rau lub PC, uas muaj kev pheej hmoo rau kev kho vajtse tsis sib haum tab sis muaj zog.

EPP (Muaj Kev Sib Tw Sib Tw)

Qhov kev sib tw txhim kho sib tw nrog rau txoj kev sib kis tau txuas nrog lub siab tshaj plaws xa mus los ntawm 1.5Mbps. Qhov kom zoo dua yog tias tsis tas yuav siv lwm daim npav hauv PC, qhov tsis muaj pes tsawg tus sib txuas (tsuav koj muaj chaw nres nkoj txaus), thiab kev teeb tsa thiab siv cov cuab yeej siv tau yooj yim. Qhov tsis zoo yog tias nws qeeb qeeb ntawm SCSI. Cov interface no yog yooj yim thiab yooj yim rau nruab thiab siv, thiab hloov SCSI interface hauv kev ua haujlwm qis kawg.

USB (Universal Serial Tsheb Sib Cuam)

Mus txog 127 ntu txuas tau txuas nrog. Tus qauv USB1.1 tam sim no muaj qhov sib kis tau ceev tshaj plaws ntawm 12Mbps, thiab muaj ib ntu pabcuam xa mus rau cov ntaub ntawv xa cov ntaub ntawv qis. Nyob rau hauv lub neej yav tom ntej, yog tias muaj USB2.0 tus qauv ntsuas barcode, lub nrawm yuav raug txuas ntxiv rau 480M / s. Nrog kub ntsaws muaj nuj nqi, ntsaws thiab ua si. Lub barcode scanner ntawm lub interface no maj mam nrov npe nrog kev tsim thiab txhawb nqa ntawm USB txheej txheem nyob rau hauv kev thawb ntawm Intel.

PS2 (keyboard interface)

Zoo ib yam li USB siv, lub taub hau ntse hloov dua siab tshiab yuav tsum tau, uas feem ntau suav nrog rab phom scanning yuav. Tseem muaj ntau lub tuam txhab siv PS2 interface.
