Tsatanetsatane RS-485 ndi muyezo wamagetsi okha. Mosiyana ndi mawonekedwe athunthu, omwe amatanthauzira magwiridwe antchito, makina, ndi mawonekedwe amagetsi, RS-485 imangotanthauzira mawonekedwe amagetsi a madalaivala ndi olandila omwe angagwiritsidwe ntchito kukhazikitsa chingwe cholumikizira ma multidrop. Muyezo uwu, komabe, uyenera kutchulidwa ndi miyezo yapamwamba, monga DL/T645, mwachitsanzo, yomwe imatanthawuza njira yolumikizirana. pamagetsi amagetsi amagetsi ku China, kutchula RS-485 ngati muyezo wosanjikiza. Zomwe zili ndi 1.Kutentha kwamoto, kutentha kwamoto 2.Kugwira ntchito bwino kwambiri, kukhazikika kwa mankhwala 3.kuthamanga kwabwino kwambiri chifukwa chogwiritsa ntchito polyethylene yapamwamba yotchinga chingwe chotchinga 4.Kukaniza kusokoneza kwa electromagnetic chifukwa chogwiritsira ntchito Kupangidwa kwa mtundu watsopano wa chotchinga cha aluminiyamu, chotchinga chamkuwa chokhala ndi zigawo ziwiri. Zizindikiro za RS-485 zimagwiritsidwa ntchito pamakompyuta osiyanasiyana komanso makina opangira makina. Pakompyuta, SCSI-2 ndi SCSI-3 zitha kugwiritsa ntchito izi kuti zigwiritse ntchito kusanjikizana kwa data pakati pa wowongolera ndi disk drive. RS-485 imagwiritsidwa ntchito polumikizana ndi data yotsika kwambiri pamabasi amagalimoto oyendetsa ndege. Zimafunika mawaya ochepa ndipo zimatha kugawana mawaya pakati pa mipando ingapo, kuchepetsa kulemera.
