Rs232 yog ib tus qauv kev sib txuas lus, thaum DB9 yog qhov txuas ntawm lub cev. Ob feem ntau siv ua ke, tab sis lawv tsis yog qhov sib npaug.
Rs232 thiab DB9 WIRING DUARAM
1. RS232
Ntsiab lus: RS232 yog cov qauv sib txuas lus serial uas txhais cov yam ntxwv hluav taws xob thiab teeb liab tswj cov ntaub ntawv kis tau. Nws yog dav siv rau kev sib txuas lus ntawm cov khoos phis tawm thiab cov khoom sab nraud, xws li cov modems, printers, sensors, thiab lwm yam.
Muaj nuj nqi: RS232 txhais cov qauv ceev, cov qauv ntaub ntawv, cov paib hluav taws xob, thiab lwm yam. Ntawm cov ntaub ntawv sib kis los ua kom muaj kev sib txuas ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv.
Daim Ntawv Thov: Feem ntau yog siv nyob rau hauv cov xwm txheej uas taw tes-rau-point-rau-point-rau-point-rau-taw tes-rau-taw tes-qhia, xws li thaum ntxov Computer Serial cov chaw nres nkoj, thiab lwm yam.
2. DB9
Ntsiab lus: DB9 yog ib qho kev sib txuas ntawm 9-tus lej DB9 txuas yog feem ntau siv rau kev sib txuas lus, tab sis nws tsis txwv kev siv cov txheej txheem.
Muaj nuj nqi: DB9 txuas tau 9 pins, txhua tus tuaj yeem muab cov teeb liab sib txawv. Feem ntau nws yog siv los ua ke nrog RS232 raws, tab sis kuj tseem siv tau rau lwm txoj kev sib txuas lus.
Daim ntawv thov: DB9 interface tsis yog tsuas yog dav siv nyob rau RS232, tab sis kuj tseem siv tau rau lwm lub sijhawm xws li muaj peev xwm caij npav, thiab lwm yam.
Lub ntsiab
Rs232 yog ib txoj kev sib txuas lus uas txhais tau li cas cov ntaub ntawv hloov pauv ntawm cov khoom siv.
DB9 yog ib daim ntawv txuas txuas txuas ntxiv uas feem ntau siv los txuas Rs232, tab sis kuj tseem siv tau rau lwm cov txheej txheem.
