Igiciro cyo hasi kuri Fibre Optic Cable - amafaranga 485 yagoretse 2 yibanze 3 yibanze 4 cores 20AWG 22AWG 18AWG - AIXTON

Ibisobanuro RS-485 nibisanzwe byamashanyarazi. Bitandukanye nuburinganire bwuzuye, busobanura imikorere, ubukanishi, n’amashanyarazi, RS-485 isobanura gusa ibiranga amashanyarazi biranga abashoferi nabakira byakoreshwa mugushira mu bikorwa umurongo uhuza imirongo myinshi. Ibipimo ngenderwaho, ariko, bigamije kwerekanwa nu rwego rwo hejuru, nka DL / T645, kurugero, rusobanura protocole y'itumanaho. kuri metero zikoresha ingufu za elegitoronike mubushinwa, zerekana RS-485 nkibipimo bifatika. Ibintu aluminiyumu, ibice bibiri-bikozwe mu muringa mesh ikingira. Porogaramu ibimenyetso RS-485 bikoreshwa muburyo butandukanye bwa mudasobwa na sisitemu zo gukoresha. Muri sisitemu ya mudasobwa, SCSI-2 na SCSI-3 barashobora gukoresha ibi bisobanuro kugirango bashyire mubikorwa urwego rwumubiri rwo kohereza amakuru hagati ya mugenzuzi na disiki ya disiki. RS-485 ikoreshwa mu itumanaho ryihuse ryamakuru muri bisi yindege ya cabine. Irasaba insinga ntoya kandi irashobora kugabana insinga hagati yintebe nyinshi, kugabanya ibiro.
