Ib lub jumper yog cov hlau uas tshem tau lossis cov yas me me lossis hlau ntsaws uas nws qhov tsis tuaj lossis qhov chaw tso rau ntawm cov khoom siv kho vajtse txiav txim siab seb cov khoom siv yuav raug teeb tsa li cas. Nws ua haujlwm los ntawm kev qhib lossis kaw ib feem ntawm lub voj voog.
Piv txwv li, yog tias lub jumper ntawm lub hard drive nyob hauv "Txoj Haujlwm A" (peb tau tsim qhov no), nws yuav txhais tau tias lub hard drive yog thawj lub hard drive ntawm lub kaw lus. Yog hais tias lub jumper nyob rau hauv "Txoj hauj lwm B" nws yuav txhais tau hais tias lub hard drive yog ib tug thib ob hard drive nyob rau hauv lub computer.
Jumpers (tseem hu ua shunt jumpers) muaj tag nrho tab sis hloov kho kho vajtse qub txheej txheem hu ua DIP hloov. Txawm tias jumpers tsis tshua muaj nyob rau feem ntau cov khoom siv tshiab niaj hnub no vim yog kev teeb tsa tsis siv neeg thiab software tswj kev teeb tsa.
Qhov Tseeb Tseem Ceeb Txog Jumpers
Lub cuab yeej koj hloov lub jumpers ntawm yuav tsum tau kaw. Nrog lub cuab yeej qhib, nws yooj yim dhau los kov lwm cov hlau lossis cov xov hlau uas yuav ua rau muaj kev puas tsuaj lossis tsis xav hloov pauv rau lub cuab yeej teeb tsa.
Ib yam li thaum cuam tshuam nrog lwm cov khoom siv hauv computer, nws tseem ceeb heev uas yuav tsum hnav lub dab teg los tiv thaiv zoo li qub lossis qee yam khoom siv hluav taws xob los tiv thaiv kev xa hluav taws xob mus rau cov khoom, uas tuaj yeem ua rau lawv puas tsuaj.
Thaum lub jumper raug txiav txim siab "rau," nws txhais tau tias nws tau npog tsawg kawg ob tus pins (qhov no kuj txhais tau tias nws yog "kaw jumper"). Ib lub jumper uas yog "tawm" yog txuas rau ib tus pin nkaus xwb. Ib qho "qhib jumper" yog thaum tsis muaj tus pins npog nrog lub jumper.
Strapping yog qee zaum lo lus siv rau txheej txheem ntawm kev teeb tsa lub jumper. Feem ntau koj tuaj yeem siv koj cov ntiv tes los kho lub jumper, tab sis rab koob-qhov ntswg pliers feem ntau yog lwm txoj hauv kev zoo dua.
Kev Siv Feem ntau rau Jumpers
Ntxiv rau cov khoom siv khoos phis tawj zoo li lub hard drive, lub jumper tuaj yeem siv rau hauv lwm yam khoom siv, ib yam li modems thiab suab phaib.
Ib qho piv txwv yog nyob rau hauv qee qhov chaw nres tsheb qhov chaw deb. Cov hom remotes yuav tsum muaj jumpers nyob rau hauv tib txoj hauj lwm raws li cov jumpers nyob rau hauv lub chaw nres tsheb qhov rooj txais. Yog tias txawm tias ib lub jumper ploj lawm lossis tsis raug, cov chaw taws teeb yuav tsis nkag siab yuav ua li cas sib txuas lus nrog lub qhov rooj tsheb. Zoo sib xws yog lub qab nthab kiv cua tej thaj chaw deb.
Nrog cov chaw taws teeb no, hloov qhov twg cov jumpers feem ntau yog kho qhov zaus ntawm cov chaw taws teeb kom nws tuaj yeem ncav cuag lub cuab yeej uas tau mloog ntawm tib zaus.
Xav paub ntxiv ntawm Jumpers
Qhov txiaj ntsig loj tshaj plaws ntawm kev siv jumpers yog tias lub cuab yeej teeb tsa tuaj yeem hloov pauv tsuas yog hloov lub cev ntawm txoj haujlwm ntawm jumper. Lwm txoj hauv kev yog tias firmware hloov pauv cov chaw, uas ua rau cov khoom siv tsis tshua muaj peev xwm ua raws li txhua lub sijhawm vim tias cov firmware tau yooj yim cuam tshuam los ntawm software hloov pauv xws li tsis txhob txwm ua yuam kev.
Qee zaum, tom qab txhim kho IDE / ATA hard drive thib ob, koj tuaj yeem pom tias lub hard drive yuav tsis ua haujlwm tshwj tsis yog lub jumper tau teeb tsa kom raug. Feem ntau koj tuaj yeem txav lub jumper ntawm ob tus pins uas yuav ua rau nws thib ob lossis thawj tsav-lwm qhov kev xaiv yog txav nws mus rau cable xaiv.
Cov khoos phis tawj qub tuaj yeem siv jumpers los pib dua BIOS nqis, tshem tawm CMOS cov ntaub ntawv, teeb tsa qhov hluav taws xob, lossis txawm teeb tsa qhov ceev ntawm CPU.
Ib pawg ntawm ntau lub jumper pins uas tau sau ua ke feem ntau hu ua jumper block.
Plug thiab Ua Si tshem tawm qhov xav tau los kho jumpers ntawm lub cuab yeej. Txawm li cas los xij, qee cov khoom siv tuaj nrog cov lus qhia rau kev tswj cov jumpers yog tias koj xav kho qhov teeb tsa-nws tsuas yog tsis xav tau zoo li nws muaj ntau cov khoom qub qub.
