USB pinouts phezu umbadlana, yini, kuphi futhi kanjani

yesimanje kakhulu amadivayisi neuropathy uxhumeke nge ibhasi serial jikelele. Ngakho-ke, i-pinouts USB kwi umbadlana ifeza indima ebaluleke kakhulu kule khompyutha yesimanje. Kukhona izindlela ezimbili ukufaka nezixhumi ezinjalo. Eyokuqala - iyona ukufakwa ngqo ebhodini. Ngesikhathi esifanayo lapho ebonakala ohlangothini emuva futhi ngokushesha isilungele ukusetshenziswa. Kodwa akulona njalo elula ukuxhuma - ngakho-ke athuthukile ngenye indlela. Ingqikithi Its okulungiselelwe esihlalweni kwi PC ibhodi main, bajoyine izintambo kusukela aphambi komtshina. Futhi ngaphezu kwaso, futhi Isixhumi.

Isakhiwo jikelele serial port USB 2.0 ejwayelekile 4 oxhumana. Eyokuqala yalezi lumiswa "+ 5V". Ngalo inikeza amandla idivayisi neuropathy. Eyesibili neyesithathu - oxhumana okuyiwona Imininingwane idluliselwa. Basuke okhonjiswe «Idatha-» (lokususa idatha) kanye «IDATHA +» (plus idatha). Kugcine, 4th, okubandakanya pinouts USB kwi umbadlana, kuba «GND» - supply komhlaba. Ngokuhambisana amazinga namuhla, basuke kuboniswa imibala ezilandelayo: ukudla - obomvu, «Idatha-» - omhlophe, «IDATHA +» - oluhlaza, futhi «GND» - black.

Lezi uxhumano esibonakalayo zenziwa ngababili, ngakho ibhodi kwenye iqembu yokuxhumana 2 nje ngezimbobo ze-USB isixhumi. Wiring siqukethe 9-pin 4 - omunye Isixhumi, 4 - ngakolunye, futhi ezimbili zokugcina adlala indima ukhiye okuthiwa. Ngesinye isikhathi setha pin nakwezinye akusiyo. Lokhu kwenziwa ukuze kwakungenakwenzeka ukudida kubo nokwenza uxhumano kahle. Ngokufanayo amisiwe futhi olufanelekayo aphambi komtshina. Ngakho-ke, lapho yokuxhuma ngowokuqala yesibili kufanele ufake ngaphandle kwezinkinga. Uma kungaqali, kuyobe sekudingeka ukwenze lokho ubone ukuthi wenza kahle.

Eminyakeni yamuva babe version kuthandwa wesithathu ngezimbobo ze-USB. Kuyinto kakhulu pinout ohlukile umbadlana, ngoba usebenzisa izintambo kakhulu ngaphezulu ukuze adlulisele ulwazi. Yabo kule samuntu 9. kuphela okukhulunywe ngawo ngaphambili, 4, wanezela 2 ngazimbili «Superspeed» + 2 futhi ngazimbili zohlobo olulodwa, kodwa kancane, futhi «GND Khama» - phansi ezengeziwe. Lokho a lot izintambo futhi kukhulisa izinga idatha. I izintambo ube nombala oluhlaza kuthiwa okhonjiswe onsomi - lokususa, ophuzi, owolintshi - plus, futhi omunye omnyama - earthing ezengeziwe. Njengoba ukwanda kwenani izintambo, kanye pinouts USB ku ukwanda umbadlana ngokulingana oqondile. Ukuze indinganiso enjalo isivele usetshenziswe 19 izikhonkwane. Omunye wabo - ukhiye, nenjongo yayo - wukuqinisekisa uxhumano lesifanele.

exhunywe kwi amakhompyutha zanamuhla futhi laptops elikhulu kumadivayisi eziningi ezahlukene usebenzisa Universal Bus yomkhiqizo. Iphrinta, isithwebuli, amadivayisi multifunction, flash ngemoto, ikhibhodi, igundane, namanye amadivayisi okuyinto kakhulu ukudlulisa amakhono PC - konke lokhu ixhunywe ikhompyutha kuba ngale interface. Akukhona njalo elula ukuxhuma ngemuva kwe-computer, futhi inani nezixhumi okuhlangene kungase kunganeli. Ukuze uxazulule le nkinga futhi wenze pinouts USB kwi umbadlana elikuvumela ukwandisa isibalo nezimbobo.
