Taura pouwhanga null: whakaahuatanga atanga, mahi Wiring

Manufacturers o farii amiorangi ia wā tukua whakahōunga ki te pūmanawa o te taputapu, whakatika i ngā roto reira, me te pai ake mahi ranei tāpiri etahi āhuatanga hou.

Hei whakapai ake i te mārō, me tuatahi tikiake koe i te reira ki to koutou PC, a ka hono i te kaiwhiwhi ki te PC, me te tīmata anō te hōtaka. Hoki te rorohiko hono ki te kaiwhiwhi o tohu amiorangi te whakamahi i te taura null pouwhanga. Ki te kore koe e whai i te atanga taua, e taea te hokona i te reira i te nuinga o toa rorohiko, ahakoa kahore tonu, i enei hua reira. I roto i tetahi take, whai koe te whiriwhiri: ki te rapu i te otinga turnkey ranei ki te hanga i te taura i whakakahore-pouwhanga koe. Ko nui ngawari te kōwhiringa o muri.

Me pēhea te ki te hanga i te whakakahore i-pouwhanga RS-232 taura?

Hoki tona production, Me matou te taura e wha-matua (roa whakaritea e te kaiwhakamahi) me rua RS-232 momo tūhono ( "whaea"). taea ēnei tūhono te kitea i roto i tetahi reo irirangi, he tino rongonui ratou, kia rite ki te hunga hakari i roto i tata nga rorohiko whaiaro rite te tauranga COM. Cable taea te mahi rite te rua miro. Hoki tenei ka whiria ia o nga otaota, ka tiki i te conductors wha. Next, Me koe ki te pupuri i tūhono pinout. he tika ki te ārai i taiawhio kōpeka reira, pera ka arahi ai ki te kore o te taputapu. he taura korenga pouwhanga taua Ka mahi te reira i stably ki te roa waea o te 50 mita.

Tūtohutanga mō te whakapiringa

E kore te mea āki tenei ako, engari kei te whakamatauria reira i roto i te mahi:

1. E kore e kōnae atu aua titi anō i runga i ngā tūhono.

Me 2. He pūhui kuhunga tūhono mō te ahotea whakakapi, t. K. Ki te whakaaro ki te tinana pūrere. Kore i reira he he tūpono ki te tahu i te atanga COM i runga i te rorohiko kaiwhiwhi ranei. E kore te mea e tika ana tenei pūhui ki te tangata whenua te taputapu katoa kei te.

3. Arā whakamahi i te taura paruruhia, no te mea mahi pai.

4. I roto i te katoa tuners amiorangi tohu ko te toru noa hoapā.

5. I roto i te tahi mau farii e kore e whai maramara MAH232 (mana'o e ka tū te reira i roto i te pūurutau waho). I roto i taua pūrere i runga i te tauranga COM e whai wāhi ngä wha o te kaiwhiwhi, Heoi, ko te putanga o te pūurutau - te taua e toru titi. Na reira, i mua i te hono koe i te taura pouwhanga whakakahore, e hiahia ana koe ki te ako i roto i te taipitopito te tuhinga mo koutou pūrere kia hiahia tuatahi ki te tāpiri i te pūurutau.

6. I roto i te tahi mau tuners titi 2 me 3 i runga i te Huri tūhono. I roto i tenei take, ka hiahia koe i te tika i roto i te taura, e kore te crossover. I roto i te tikanga ki te whakatau he aha te momo o te tūhono te tu i runga i to koutou kaiwhiwhi, kia titiro koe tona tuhinga.

7. tūtohutia te taura paea mo te whakamahi, mai te mea te reira atu ātete ki te ahotea aunoa. hoapā soldered he pai ki te whakaki i ki silicone i roto i te tikanga ki te karo poto-iahiko.

Waea RS232 taura pouwhanga-kore

Me konuhono te atanga COM katoa toru hoapā me te whare tūhono. I roto i te taura taua he e tika ana ki te whakamahi i te 2, 3 me te 5 hoapā. I roto i te whakatinanatanga, kua soldered te korenga pouwhanga hoapā taura raraunga tika i roto i te ara ano tūhono e rua, me te crosswise 2 me 3 e interchanged.
