RS-485 ni igipimo ngenderwaho cy’amashanyarazi gusa. Bitandukanye n’ibipimo ngenderwaho byuzuye, bigena imikorere, imiterere, n’amashanyarazi, RS-485 isobanura gusa imiterere y’amashanyarazi y’ibikoresho bigenzura n’ibyakira bishobora gukoreshwa mu gushyira mu bikorwa umurongo uhuza amanota menshi. Ariko, iyi gipimo ngenderwaho igamije gushingira ku bipimo ngenderwaho byo ku rwego rwo hejuru, nka DL/T645, urugero, isobanura protocol y’itumanaho ku bipimo ngenderwaho by’ingufu z’ikoranabuhanga mu Bushinwa, ikagaragaza RS-485 nk’igipimo ngenderwaho cy’urwego nyarwo. Ibiranga: 1. Irinda ubushyuhe kandi irinda umuriro. 2. Imikorere myiza yo gukingira no kudahungabana kw’imiti. 3. Imikorere myiza yo kohereza amakuru bitewe no gukoresha polyethylene nziza mu kurinda insinga. 4. Kurwanya neza ingaruka z’amashanyarazi bitewe no gukoresha ubwoko bushya bwa aluminiyumu n’uburinzi bw’umuringa bugizwe n’ibice bibiri. Imikoreshereze: Ibimenyetso bya RS-485 bikoreshwa mu buryo butandukanye bwa mudasobwa na sisitemu zikora. Muri sisitemu ya mudasobwa, SCSI-2 na SCSI-3 bishobora gukoresha iyi ngingo kugira ngo bishyire mu bikorwa igipimo ngenderwaho cy’uburyo bwo kohereza amakuru hagati y’igikoresho kigenzura n’ikinyabiziga cya disiki. RS-485 ikoreshwa mu itumanaho ryihuse ry’amakuru mu modoka zitwara abagenzi mu byumba by’indege z’ubucuruzi. Isaba insinga nke kandi ishobora gusangira insinga hagati y’imyanya myinshi, bigabanyiriza uburemere.
