Nā kikoʻī
He kūlana uila wale nō ʻo RS-485. ʻAʻole e like me nā kūlana interface piha, e wehewehe ana i nā kikoʻī hana, mechanical, a me nā uila, wehewehe wale ʻo RS-485 i nā ʻano uila o nā mea hoʻokele a me nā mea loaʻa e hiki ke hoʻohana ʻia e hoʻokō i kahi laina hoʻoili multipoint kaulike. Eia naʻe, ua manaʻo ʻia kēia kūlana e kuhikuhi ʻia e nā kūlana kiʻekiʻe, e like me DL/T645, ka mea e wehewehe ana i ke protocol kamaʻilio.
no nā mika ikehu uila ma Kina, e kuhikuhi ana iā RS-485 ma ke ʻano he kūlana papa kino.

1. Kūpaʻa wela, pale ahi
2. Hana hoʻokaʻawale maikaʻi loa, hana kemika paʻa
3. Hana hoʻoili maikaʻi loa ma muli o ka hoʻohana ʻana i ka polyethylene kiʻekiʻe no ka pale ʻana i ke kaula ulana
4. Ke kūpaʻa kūpono i ka hoʻopilikia electromagnetic ma muli o ka hoʻohana ʻana i kahi ʻano hou o ka foil alumini, ka pale ʻana pālua o ka ʻupena keleawe ulana.

Hoʻohana ʻia nā hōʻailona RS-485 ma kahi ākea o nā ʻōnaehana kamepiula a me ka automation. Ma kahi ʻōnaehana kamepiula, hiki iā SCSI-2 a me SCSI-3 ke hoʻohana i kēia kikoʻī e hoʻokō i ka papa kino no ka hoʻoili ʻikepili ma waena o kahi mea hoʻokele a me kahi disk drive. Hoʻohana ʻia ʻo RS-485 no nā kamaʻilio ʻikepili wikiwiki haʻahaʻa i nā kaʻa kaʻa ma nā keʻena mokulele kalepa. Pono ia i ka liʻiliʻi o ke kaula a hiki ke kaʻana like i ke kaula ma waena o nā noho he nui, e hōʻemi ana i ke kaumaha.
