'O ka USB ma ka papa pahuhopu: pehea, kahi a me pehea

Most kēia ʻike ākea manaʻo e pili ana i kekahi paʻa pūkaʻina kaʻa 'ohua. No laila, ke kuhi nei'o USB ma ka motherboard i ke kuleana nui i ka hana o kahi kamepiula hou. 'Elua ala e ho'ohui ai i kēia mau pūnaewele. 'O ka mua e kau pololei'ia ma luna o ka papa. I ka manawa like, ua hō'ike'ia ma ka'ao'ao hope a ua ho'omākaukau koke'ia no ka ho'ohana. Akā,'a'ole ia he manawa ma'alahi no ke ku'i'ana - a no laila ua kūkulu'ia kekahi ala'ē a'e. Aia kona kumu i loko o ka noho noho ma luna o ka papahana PC nui, kahi i ho'ohui'ia ai nā wiwa mai ka'ao'ao mua. Aia ma luna o laila he pūhaka.

Ka 'ole o ka paʻa pūkaʻina awa USB 2.0 maʻamau i 4 E leka pepa. 'O ka mua o lākou ua kapa'ia'o "+ 5B". Hā'awi ia i ka mana i ka mea kikowaena. 'O ka lua a me ke kolu he mau kipa, kahi i lawe'ia ai ka'ike. Ka mea, i denoted e «DATA-» (huaʻikepili) a «ʻikepili +» (eia kekahi ʻikepili). Hope, i ka 4th, i ka loaʻa o ke USB pinouts ma ka motherboard, ia mea «GND» - ka lako o ka aina. E like me nā kūlana i'ae'ia i kēia lā, ua koho'ia lākou e nā kala e like nei: mana -'ula'ula, "DATA-" - ke'oke'o, "DATA" "-'ōma'oma'o, a me" GND "-'ele'ele.

'O ia mau pilina waena ke hana'ia i pai pālua, no laila ma luna o ka papa ma kahi hui hui e hiki koke i nā loulou USB 2. Aia ka pin i 9 mau helu: 4 - ho'okahi hono, 4 - ma kekahi, a'o nā hope hope'elua e ho'okani i ka hana o ka kī i kapa'ia. Aia kahi kui ma kahi ho'okahi, akā, ma kahi'ē a'e,'a'ole. Ua hana'ia kēia i hiki'ole ke ho'ololi a pili pono. Pēlā, ua hana'ia ke kūpono mai ka'ao'ao mua. No laila, i ka ho'ohui'ana i ka mua i ka lua, pono e ho'okomo'ia me ka pilikia. Inā hiki'ole kēia, pono'oe e'ike inā'oe e hana ana i nā mea a pau.

I kēia mau lā, ua loa'a ka laulā'ekolu o ka pae USB. 'O ka'ōmahi ma ka motherboard he mea'oko'a loa ia, no ka mea, ua ho'ohana nui'ia nā'oni e lawe i ka'ike. He 9 wale nō o lākou e pili ana i ka 4. i hō'ike mua'ia. E hui pū'ia nā pai o Superspeed + a me 2 mau'ano o ka'ano like'ole, akā me kahi mea iki wale nō, a me "GND Drain" - kahi hou. O ia ka leo o ka hailonaʻana o nā kaula a me maoli i ka ʻikepili kōmi. 'O nā kaula i loko o ko lākou mau lawai'a e like me ka uliuli, ke'ula'ula - mino, melemele,'alani - me nā, a ho'okahi a'e'ele'ele - kahi hou. I ka ho'onui'ana o ka hua'ōlelo, pi'i ka USB ma luna o ka motherboard i ke kaulike pololei. No kēia papa, 19 mau mea i ho'ohana mua'ia. 'O kekahi o lākou he kī nui, a'o kāna kumu no ka hō'oia'ana i ka pilina pololei.

Me ke kōkua o kahi ka'a pūnaewele puni honua, hiki i nā pūnaewele like'ole e pili i nā kamepiula hou a me nā kamepiula. 'O ke kelepona, ka scanner, nā polokalamu mulipuna, nā'ōkuhi flash, ka keyboard, ka'iole a me nā mea'ē a'e e ho'onui i ka mana o ka PC - e pili kēia a pau i ka kamepiula ma kēia'oko'a. 'A'ole i ma'alahi ka ho'ohui'ana i ka hope o ka lolouila, a'a'ole paha i lawa ka helu o nā pūnaewele integrated. No ka ho'oholo'ana i kahi pilikia e hana'ia ai ka pino o ka USB ma ka motherboard, e hiki ai ke ho'onui i ka helu o nā awa.
