RS485 puas tuaj yeem siv RS232 adapter?

1, Sib piv ntawm RS232 thiab RS485 Interface Standards
Cov yam ntxwv hluav taws xob: RS232 siv cov logic tsis zoo, nrog cov logic "1" xws li ntawm -3V rau -15V thiab logic "0" xws li ntawm +3V mus rau {{6} }V. RS485 siv cov teeb liab sib txawv, thiab nws cov ntsiab lus hauv lub xeev yog txiav txim siab los ntawm qhov sib txawv ntawm ob lub xov hlau.
Tus nqi sib kis: Tus nqi sib kis ntawm RS232 feem ntau yog qis dua 20kbps, thaum tus nqi sib kis ntawm RS485 tuaj yeem ncav cuag 10Mbps.
Kev sib kis nrug: Qhov kev sib kis ntawm RS232 yog luv luv, feem ntau tsis pub dhau 15 meters. Qhov kev ncua deb ntawm RS485 tuaj yeem ncav cuag 1200 meters lossis ntev dua.
Kev sib txuas ntau yam khoom siv: RS232 yog kev sib txuas lus taw tes rau-taw tes, feem ntau tsuas yog ib lub cuab yeej tuaj yeem txuas tau. RS485 txhawb nqa ntau yam khoom sib txuas thiab tuaj yeem tsim tau lub cuab yeej network.
2, Kev tsom xam ua tau ntawm RS485 thiab RS232 adapters
Vim muaj qhov sib txawv tseem ceeb hauv cov yam ntxwv hluav taws xob thiab cov ntaub ntawv sib kis ntawm RS485 thiab RS232, nws feem ntau tsis tuaj yeem txuas ncaj qha rau ob qhov kev sib txuas no siv lub converter yooj yim lossis adapter. Hom adapter no tsis tuaj yeem daws teeb meem theem kev hloov pauv thiab teeb meem sib kis sib txawv, yog li nws tsis tuaj yeem lav qhov raug thiab ruaj khov ntawm cov ntaub ntawv xa mus.
Txawm li cas los xij, muaj tseeb qee qhov hloov pauv lossis hloov pauv ntawm lub khw uas thov kom muaj peev xwm hloov pauv ntawm RS485 thiab RS232. Cov converters no feem ntau muaj cov teeb liab ua tiav thiab kev hloov pauv hloov pauv uas tuaj yeem ua qhov tsim nyog hloov pauv thiab kev ua haujlwm sib txawv ntawm cov teeb liab kom ua tiav qhov sib txawv ntawm cov qauv sib txawv.
Thaum siv xws li converters, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
Qhov zoo ntawm converters: Tsis yog txhua tus converters tuaj yeem muab kev ua haujlwm ruaj khov thiab txhim khu kev qha. Thaum yuav khoom, cov khoom uas muaj kev ntseeg tau zoo thiab kev ntsuam xyuas zoo yuav tsum raug xaiv.
Kev sib kis tus nqi thiab kev ncua deb: Txawm hais tias siv lub converter, tus nqi sib kis thiab qhov kev ncua deb ntawm RS232 yuav tsum raug xam tias yog. Yog tias cov ntaub ntawv yuav tsum tau xa mus rau qhov ntev los yog nyob rau hauv high speeds, yuav tsum tau txiav txim siab ntau haum interface.
Kev sib txuas ntau yam khoom siv: Txawm tias siv lub tshuab hloov pauv, RS232 tseem tsuas yog txhawb nqa kev sib txuas lus ntawm qhov taw tes. Yog tias muaj ntau yam khoom siv yuav tsum tau txuas nrog, xav txog kev siv RS485 lossis lwm cov qauv kev sib txuas uas txhawb nqa ntau yam kev sib txuas.
3, Cov lus pom zoo rau kev siv
Hauv kev siv tswv yim, yog tias nws tsim nyog los txuas RS485 cov khoom siv rau RS232 cov khoom siv, qhov kev coj ua zoo tshaj plaws yog siv cov cables thiab cov khoom siv uas ua tau raws li cov qauv kev sib txuas ntawm ob tog, tsis yog kev cia siab rau cov hloov pauv. Qhov no tuaj yeem ua kom muaj kev ruaj ntseg thiab kev ntseeg tau ntawm cov ntaub ntawv xa mus.
Yog tias nws tsim nyog siv lub converter tiag tiag, nws raug nquahu kom ua cov kev tshawb fawb txaus thiab kev sim ua ntej kev yuav khoom los xyuas kom meej tias cov khoom xaiv tuaj yeem ua tau raws li qhov xav tau ntawm daim ntawv thov. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau cov peev txheej ua tau zoo thiab cov kev txwv uas cov hloov pauv tuaj yeem nqa, thiab yog tias tsim nyog, xav txog kev kho dua tshiab lossis hloov cov khoom siv kom ua tiav kev sib raug zoo thiab kev ua tau zoo.
