He paerewa hiko anake te RS-485. Kāore i rite ki ngā paerewa atanga whānui, e tautuhi ana i ngā whakatakotoranga mahi, miihini, me te hiko, ka tautuhia noa e te RS-485 ngā āhuatanga hiko o ngā kaiwhakahaere me ngā kaiwhiwhi ka taea te whakamahi hei whakatinana i tētahi raina tuku maha-ira taurite. Heoi, ko te tikanga o tēnei paerewa kia tirohia e ngā paerewa taumata teitei ake, pērā i te DL/T645, hei tauira, e tautuhi ana i te kawa whakawhitiwhiti kōrero mō ngā mita pūngao hiko i Haina, e tohu ana i te RS-485 hei paerewa paparanga tinana. Ngā Āhuatanga: 1. Ātete wera me te ātete mura. 2. Mahi whakamarumaru pai me te pumau matū. 3. Mahi tuku pai nā te whakamahinga o te polyethylene kounga teitei mō te parenga taura whiri. 4. Ātete whai hua ki te pokanoa hikohiko nā te whakamahinga o tētahi momo pepa konumohe hou me te parenga mata parahi whiri rua-paparanga. Ngā Whakamahinga: Ka whakamahia ngā tohu RS-485 i roto i te whānuitanga o ngā pūnaha rorohiko me te aunoatanga.
