Karata yanchito
1. Chingwecho chidakonzedwa kwa ma Rs-485 CREGE CRECE CREDECE NDI MALO OGWIRITSIRA NTCHITO, ETC. Zingwe zambiri zomwe zimapezeka, zimatha kugwiritsidwa ntchito kwambiri pakuwongolera, makina ogwiritsa ntchito okhaokha amagwiritsa ntchito. RS485 imalola madontho ambiri komanso chingwe kutalika kwambiri, liwiro lalikulu, motero limagwiritsidwa ntchito nthawi zambiri m'makampani ndi zinthu zokha. A RS-485 amagwiritsidwanso ntchito m'malo akuluakulu a zisudzo, makampani oyendetsa magalimoto, pomwe palibe chosatsimikizika chokhudza phokoso lotsiriza. Itha kuzindikira mtunda wautali ndikuthandiziranso zida zingapo pabasi imodzi, zitha kukwaniritsa ntchito zambiri zomwe zimafunikira mtundu wa mawonekedwe a stabite.it ndi mtundu wamakampani opanga mafakitale. Rs-485 imatchedwanso ngati TIA-485 kapena EIA-485.
