2021 isitayela esisha se-Outdoor Fiber Optic Cable - Rs485 esontekile 2 core 3 core 4 cores 20AWG 22AWG 18AWG - AIXTON

Imininingwane

I-RS-485 iyindinganiso kagesi kuphela. Ngokungafani namazinga okusebenzelana okugcwele, achaza ukucaciswa kokusebenza, komshini, kanye nogesi, i-RS-485 ichaza kuphela izici zikagesi zabashayeli nabamukeli abangasetshenziswa ukuze kusetshenziswe ulayini wokudlulisela we-multidrop olinganiselayo. Leli zinga, nokho, kuhloswe ngalo ukuthi kubhekiselwe kumazinga aphezulu, njenge-DL/T645, isibonelo, echaza umthetho olandelwayo wokuxhumana.

kumamitha wamandla kagesi e-China, ecacisa i-RS-485 njengezinga elijwayelekile lesendlalelo esibonakalayo.

Izici

1.Ukumelana nokushisa, ukumelana nelangabi

I-2.ukusebenza okuhle kakhulu kokufakwa, ukusebenza kwamakhemikhali okuzinzile

3.ukusebenza kahle kokudlulisa ngenxa yokusetshenziswa kwe-polyethylene yekhwalithi ephezulu yokuvikela ikhebula elilukiweyo

4.Ukumelana okuphumelelayo nokugxambukela kwe-electromagnetic ngenxa yokusetshenziswa kohlobo olusha lwe-aluminium foil, i-mesh yethusi ephothiweyo evikela izendlalelo ezimbili.

Izinhlelo zokusebenza

Izimpawu ze-RS-485 zisetshenziswa ezinhlobonhlobo zamakhompiyutha kanye nezinhlelo ezizenzakalelayo. Ohlelweni lwekhompiyutha, i-SCSI-2 ne-SCSI-3 ingasebenzisa lokhu kucaciswa ukuze kuqalise isendlalelo esibonakalayo sokudlulisa idatha phakathi kwesilawuli nedrayivu yediski. I-RS-485 isetshenziselwa ukuxhumana kwedatha enesivinini esiphansi emabhasini ezimoto zendiza yezindiza. Idinga izintambo ezincane futhi ingabelana ngezintambo phakathi kwezihlalo eziningi, kwehlise isisindo.
