Ko te tauranga whakawhitiwhiti RS485 he whakaahuatanga taputapu mō ngā tauranga whakawhitiwhiti. Kei roto i te āhua pahi te aratau waea o te tauranga RS485, ā, e 32 ngā pūnga ka taea te hono atu ki te pahi kotahi. I roto i te whatunga whakawhitiwhiti RS485, ko te tikanga ka whakamahia e te whatunga whakawhitiwhiti te aratau whakawhitiwhiti matua-pononga, arā, he kaihautū me ngā pononga maha. I te nuinga o te wā, ka honoa noa ngā hononga whakawhitiwhiti rS-485 ki ngā pito "A" me "B" o ia atanga me ngā taura takirua takirua A. Ko tēnei hononga whakawhiti raraunga he aratau whakawhitiwhiti haurua-rua. Ka taea anake e te taputapu te tuku, te whiwhi rānei i ngā raraunga i tētahi wā kua whakaritea. I muri i te whakatūnga o te atanga whakawhitiwhiti taputapu, me whakaae he kawa raraunga i waenga i ngā taputapu tuku raraunga kia taea ai e te pito whiwhi te wetewete i ngā raraunga kua whiwhi, koinei te ariā o te "tikanga". He whakatakotoranga kawa paerewa kotahi te kawa whakawhitiwhiti, ā, e whakamahi ana ā mātou hua katoa i te kawa Modbus-RTU paerewa. Ko te tawhiti whakawhitiwhiti mōrahi o te Rs-485 he 1219m. I te tere iti, i te tawhiti poto, kāore he wā pokanoa, ka taea te whakamahi i te aho miro-takirua noa. I te tere teitei, i te tuku aho roa, me whakamahi i te taura motuhake RS485 taurite aukati (te tikanga 120 ω), ā, i roto i te taiao pokanoa kino, me whakamahi hoki i te taura parepare miro-takirua.
