RS-485, tseem hu ua TIA-485 lossis EIA-485, yog tus qauv txhais cov yam ntxwv hluav taws xob ntawm cov neeg tsav tsheb thiab cov neeg txais khoom siv rau kev sib txuas lus sib txuas. Kev taw qhia hluav taws xob yog qhov sib npaug, thiab ntau lub tshuab tau txais kev txhawb nqa.
RS485 siv rau dab tsi?
RS-485 yog dab tsi? RS-485 yog ib qho kev qhia tshwj xeeb uas txhais cov hluav taws xob cuam tshuam thiab lub cev txheej rau kev sib txuas lus ntawm cov khoom siv hluav taws xob. Tus qauv RS-485 tso cai rau kev ncua deb ntawm cov hluav taws xob tsis zoo thiab tuaj yeem txhawb nqa ntau yam khoom siv ntawm tib lub npav.
Qhov txawv ntawm RS232 thiab RS485 yog dab tsi?
RS232 yog ntau tshaj qhov ua tau rau qhov kev ncua deb thiab cov ntaub ntawv ceev tsawg. RS232 muaj kev sib kis ceev ntawm 1Mb / s mus txog 15M. Txawm li cas los xij, RS485 muaj cov ntaub ntawv kis ceev mus txog 10Mb / s rau qhov deb ntawm 15M. Ntawm qhov siab tshaj plaws ntawm 1200M, RS485 kis ntawm 100Kb / s.
RS txhais li cas hauv RS485?
EIA ib zaug sau tag nrho nws cov qauv nrog lub npe "RS" (Pom zoo Standard), tab sis EIA-TIA tau hloov "RS" nrog "EIA / TIA" rau pab txheeb xyuas lub hauv paus ntawm nws cov qauv.
RS485 cable yog dab tsi?
EIA-485 (yav tas los RS-485 lossis RS485) yog ib qho tshwj xeeb rau lub cev txheej ntawm lub network uas siv qhov sib txawv ntawm qhov voltages ntawm ob lub xov hlau (Peb xaim) rau conveys cov ntaub ntawv. … Qhov kev tawm tsam ntawm tus khub twistedcable yuav poob qhov voltage sib txawv raws li nws mus rau hauv cov hlau.
