I roto i ngā mahi ahumahi, te aroturuki mamao, me ngā pūnaha pūoko tino tika, kua puta ake te RS422 hei paerewa whakawhitiwhiti raupapa pumau me te whai hua. He whānuitia te whakamahinga i roto i ngā waeine ine tawhiti, e whakakotahi ana i ngā kaha tuku tawhiti me te ātete haruru pai rawa atu, e waiho ana hei atanga nui i roto i ngā pūnaha ine tawhiti hou.
1. He aha te RS422?
Ko te RS422 (Paerewa Rekomendasi 422) he paerewa whakawhitiwhiti raupapa i whakawhanakehia e te Electronic Industries Alliance (EIA) e tautuhi ana i te tuku tohu rerekētanga. He rerekē ki te atanga RS232 tuku iho, ka whakamahia e te RS422 he takirua raina tohu tautoko hei tuku raraunga. Ka tino whakapai ake tēnei tuku rerekētanga i te ātete haruru me te pono o te whakawhitiwhiti kōrero.
2. Ngā Āhuatanga Hangarau Matua o te RS422
Aratau Tuku: Tohu rerekētanga (takirua miro)
Tere Tuku Mōrahi: 10 Mbps (i ngā tawhiti poto ake)
Te Tawhiti Tuku Mōrahi: Tae atu ki te 1200 mita (i ngā tere iti iho)
Te Tau Mōrahi o ngā Pūnga: 1 taraiwa ki te 10 kaiwhiwhi
Waea Tohu: Ko te tikanga he 4 ngā waea (TX+/TX–, RX+/RX–)
Ārai Haruru: Teitei (he pai mō ngā taiao hikohiko matatini)
Aratau Whakawhitiwhiti: Ira-ki-maha-ira (taraiwa kotahi ki ngā kaiwhiwhi maha)
3. Ngā Painga o te RS422
①Tuku Tawhiti-Roa
Ka tautoko te RS422 i te tuku raraunga tae atu ki te 1200 mita te tawhiti, he mea tino pai mō ngā tono e tika ana kia tukuna ngā raraunga ine puta noa i ngā wāhi rerekē, i ngā taputapu rerekē rānei.—pērā i te ruri rēriwe, te aroturukitanga ā-rohe, me ngā mahi whakahaere whare putunga.
②Ārai Haruru Kaha
Nā te rerekētanga o te tohu, ka taea e te RS422 te pehi i te haruru aratau-noa, kia pai ai mō ngā taiao haruru hiko, pērā i ngā tipu ahumahi, ngā whakaurunga o waho rānei.
③Te Pūmautanga Raraunga Teitei Ake
Ahakoa ngā taura roa, ngā tautuhinga hiko uaua rānei, he iti ake ngā tere ngaronga raraunga a te RS422 i ngā atanga whakawhitiwhiti kōrero kotahi-mutunga tuku iho. Mā tēnei ka pumau, ka puta hoki ngā inenga tawhiti i te wā tūturu.
④Whakawhitiwhiti Kōrero Kotahi-ki-te-Taha
Mā te RS422 ka taea e te kaihautū kotahi te kōrero ki ngā kaiwhiwhi maha, ka taea ai ngā pūnaha whānuitanga maha-kōwae he iti te utu.
4. Ngā Whakamahinga i roto i ngā Kōwae Ine Awhe Taiaho
E whakamahia whānuitia ana te RS422 i roto i ngā kōwae ine tawhiti taiaho i roto i ngā āhuatanga e whai ake nei:
Ngā Taraiwa Ārai / Ngā Papaaho Robot: I ngā wāhi e nui ana te haruru o roto o te pūnaha, ka whakarite te RS422 i te whakawhitiwhiti kōrero pumau.
Te Aroturukitanga i ngā Rohe Tawhiti: Me tuku pono ngā raraunga tawhiti ki tētahi kaiwhakahaere matua.
Ngā Pūnaha Hoia/Ahumahi: He mea nui te pono o ngā whakawhitiwhiti kōrero.
Ngā Taiao Kino (hei tauira, te pāmahana teitei me te haumākū): Ka āwhina te tohu rerekētanga ki te pupuri i te pono o ngā raraunga.
5. Aratohu Waea me ngā Whakaaro Matua
①Kauwhata Hononga Noa:
TX+ (Tuku Pai)→RX+ (Te Whiwhinga Pai)
TX–(Te Tuku Kino)→RX–(Te Whiwhinga Kino)
RX+/RX–: I runga anō i te hiahia urupare o te kōwae, ka whakamahia pea ēnei rārangi, kāore rānei.
②Ngā Tikanga Pai:
Whakamahia ngā taura takirua-whiri kua whakamarumarutia hei whakarei ake i te kaha ārai-pokanoa.
Me whakarite kia tika te taurite o te roa o te taura me te mutunga kia kore ai e whakaatahia te tohu.
Me tautoko te pūrere e whiwhi ana i te kawa RS422, me whakamahi rānei i tētahi kaitahuri RS422.
He mea tino pai te RS422 nā tōna kaha tuku me tōna pakari, ā, he mea nui tēnei mō te whakawhitiwhiti pono o ngā waeine ine tawhiti laser. Mō ngā kaiwhakamahi e hiahia ana ki te tuku tawhiti, te pumau o ngā raraunga, me te ātete kaha ki te haruru, he haumi pono, he haumi ā-mua hoki te whiriwhiri i tētahi waeine tautoko RS422.
