RS-485 ndi muyezo wamagetsi okha. Mosiyana ndi miyezo yonse yolumikizirana, yomwe imafotokoza zofunikira zogwirira ntchito, zamakina, komanso zamagetsi, RS-485 imangofotokoza makhalidwe amagetsi a owongolera ndi olandila omwe angagwiritsidwe ntchito kukhazikitsa mzere wolumikizirana wa mapointi ambiri. Komabe, muyezo uwu ukufuna kutchulidwa ndi miyezo yapamwamba, monga DL/T645, mwachitsanzo, yomwe imafotokoza njira yolumikizirana ya ma electron energy meter ku China, ndikutchula RS-485 ngati muyezo wa physical layer. Makhalidwe: 1. Yosagwira kutentha komanso yoletsa moto. 2. Kugwira ntchito bwino kwambiri pakuteteza kutentha komanso kukhazikika kwa mankhwala. 3. Kugwira ntchito bwino kwambiri pakutumiza chifukwa chogwiritsa ntchito polyethylene yapamwamba kwambiri poteteza chingwe cholukidwa. 4. Kukana bwino kusokonezedwa ndi ma electromagnetic chifukwa chogwiritsa ntchito mtundu watsopano wa aluminiyamu foil ndi zotchingira zamkuwa zolukidwa kawiri. Kugwiritsa Ntchito: Zizindikiro za RS-485 zimagwiritsidwa ntchito m'makompyuta osiyanasiyana komanso machitidwe odziyimira pawokha. Mu kompyuta, SCSI-2 ndi SCSI-3 zimatha kugwiritsa ntchito izi kuti zigwiritse ntchito physical layer yotumizira deta pakati pa wowongolera ndi disk drive. RS-485 imagwiritsidwa ntchito polumikizirana deta mwachangu m'mabasi a magalimoto onyamula anthu m'mabwalo a ndege zamalonda. Imafuna mawaya ochepa ndipo imatha kugawana mawaya pakati pa mipando ingapo, zomwe zimachepetsa kulemera.
