Ko te RS-485 he paerewa whakawhitiwhiti kōrero maha-ira, he tohu rerekētanga, he haurua-rua, e whakamahi ana i ngā taura takirua-whiri (waea matua-rua) hei tuku raraunga. Ngā mahi hononga taipitopito mō te hono i tētahi pūrere raupapa ki te atanga RS-485 o tētahiMokangā taputapu e whai ake nei:
Hipanga 1: Whakaū i te Atanga Pūrere me ngā Whakamāramatanga Pin
Tērā pea he rerekē ngā whakamāramatanga o ngā pine i waenga i ngā waitohu taputapu rerekē. He mea pai kia whakapā atu ki te kaihanga e tika ana hei whakaū i ngā whakamāramatanga pine tika i mua i te hono waea!
MOXAKo ngā momo tauranga raupapa e toru te nuinga o ngā hua:
Ko te raupapa waea atanga DB 9 me ngā tauira e tika ana koia ēnei:
Ko te raupapa waea atanga RJ 45 me ngā tauira e tika ana koia ēnei e whai ake nei
Ko te raupapa waea atanga pūrua me ngā tauira e tika ana koia ēnei:
Hipanga 2: Hono atu mā te whakamahi i ngā taura
Horopaki 1: Te hono i tētahi pūrere Moxa ki tētahi pūrere RS-485 kotahi. Ina hono ana i tētahi pūrere Moxa me tētahi pūrere raupapa, honoa ngā pine pai (B) ki ngā pine pai (B) me ngā pine kino (A) ki ngā pine kino (A).
Horopaki 2: Ina hono ana tētahi taputapu MOXA ki ngā taputapu RS-485 maha, me whakamahi he hononga mekameka-a-ringa. Ka honoa ngā pito A(+) o ngā taputapu katoa ki te rārangi pahi pai, ā, ka honoa ngā pito B(-) o ngā taputapu katoa ki te rārangi pahi kino.
Horopaki 3: Me tāpiri ngā ātete whakamutu. Mena he ātete whakamutu kua hangaia ki roto i te NPort (hei tauira, ka taea te whakatuwhera i te ātete whakamutu kua hangaia ki roto i te NPort 5450 mā te pana DIP (ko SW 3 te pana ātete whakamutu i te nuinga o te wā), kātahi ka tāpirihia he ātete whakamutu ki te pito o te hononga, e whakaaturia ana i te hoahoa i raro nei.
Horopaki 4: Mena kāore he ātete whakamutunga kua hangaia ki roto i te NPort, ka taea te tāpiri atu ki ngā taha e rua o te hononga RS-485, me te whakaatu i te waea i te hoahoa i raro nei.
