Lan-tester: hauj lwm, los

Lan-tester - ib qho kev ntsuas uas tsim los xyuas lub sam xeeb ntawm telecommunication tes hauj lwm. Feem ntau, xws ntaus ntawv muaj ib tug tseem ceeb ib feem thiab ib tug detachable (feem ntau yog ib tug, tab sis muaj cov qauv nyob rau hauv uas ib tug plurality ntawm tshem feem yog muab). Lan-tester tso cai "prozvanivat" computer network, hu xov tooj sib txuas lus, compression connectors.

Network Tester heev tswj kev ua hauj lwm thiab tej yam sij hawm tshwj xeeb cable tswv. Tom qab tag nrho, lawv txoj hauj lwm yog tsis tsuas mus rau broach kev sib txuas lus, tab sis kuj yuav debug tag nrho cov system. Dig muag, nws yog suab tsis yooj yim sua los mus txiav txim qhov zoo tshaj ntawm cov CRIMP connector, thiab nws lub nplhaib tawm nrog ib tug tester, nws yuav siv sij hawm ib tug ntau lub sij hawm thiab pab. Advancing lub twisted khub yog tsis ib txwm nyob rau hauv tib lub chav tsev, feem ntau qhov xaus ntawm lub cable yog nyob rau hauv txawv sab ntawm lub tsev thiab nyob rau txawv cov plag tsev, thiab "laaj" nyob rau hauv cov ntaub ntawv no ib tug multimeter yuav daunting thiab tsis xis nyob. Qhov ntawd yog qhov chaw uas peb tuaj nyob rau hauv muab rau cov kev pab ntawm xws li ib tug ntaus ntawv raws li lub Lan-tester.

Rau cov "laaj" hlob lub connectors ntawm ob hnub ntawm lub twisted khub. Inserting ib kawg ntawm lub cev lub ntsiab ntawm cov tester connector, thiab lub thib ob - ib tug tshem tau connector ib feem. Tom qab ntawd, peb tig rau tus ntaus ntawv thiab khiav nws nyob rau hauv kev xeem hom. Tsaug rau cov LED zaub, Lan-tester los mus txiav txim tsis tau tsuas yog lub xub ntiag ntawm so ntawm cov khub nyob ntawm tej thiab luv luv-Circuit Court, tab sis kuj mus nrhiav tau hma nyob ntawm tej.

Heev feem ntau, beginners tsis saib xyuas checking crimp connectors. Pib "prozvanivat" tsuas yog hais tias tus computer network tsis ua hauj lwm. Txawm li cas los, qhov kev xeem no yuav tsum tau nqa tawm nyob rau hauv txhua crimp connector kom peb ua tau thiab sam xeeb txog qhov kev twb kev txuas ntawm lub connector pins, tsis yog cov uas tam sim no nyob rau hauv kev siv ib lub computer network. Txwv tsis pub koj yuav tsis tau los mus tiv thaiv rau yav tom ntej uas tsis thiab system tsawg feempua sibtsoo ua.

Muaj ib tug lossis loj xaiv ntawm network testers, ob qho tib si pib xyaum ua thiab kev. Nyob rau hauv ib nutshell, Kuv xav piav txog cov kev pab cuam ntawm kev cov khoom siv.

Xws li tej zaum yuav sim tsis tau tsuas yog cov-khub, tab sis kuj hu coaxial cables. Kev cob qha cov lan-tester (cable) dhau li ntawm tus txheem kuaj piav saum toj no yuav ntsuas qhov ntev, rau qhov teeb meem laus Pib ntsais koj teeb, thiab co tes rau lub xub ntiag ntawm lub active conductors. Xws li muaj high-qib zaub, uas qhia txog tag nrho cov ntaub ntawv tsim nyog rau cov cable mob. Thiab tseem ceeb tshaj, cov pab kiag li lawm muaj ib tug loj tus naj npawb ntawm tej thaj chaw deb modules. Piv txwv li, thaum rub ntawm cables los ntawm kabelgony "networkers" yog feem ntau ntsib nrog qhov teeb meem ntawm kev qhia kom paub txog "tus kheej" cable. Duab txog qhov no: lub ua daim hlau thaiv raws qhov xaus ntawm cov officers 10-15, thiab nws tsuas yog tsis yooj yim sua kom to taub uas ib tug yog "koj li".

"Laaj" amateur tester yuav luag nyob rau ib lub sij hawm ntev, tshwj xeeb tshaj yog yog hais tias tus lwm kawg yog nyob rau hauv lwm sab ntawm lub tsev. Nyob rau hauv xws li ib tug teeb meem no yuav pab tau tej thaj chaw deb modules kev ntaus ntawv. Koj yuav muab nyob rau ib tog ntawm lub module, thiab lawv tus kheej lub thib ob kawg ntawm tus cable los ntawm txoj kev lub ntsiab chav tsev tester rau xam yuav tsum tau hlau.

Yuav kom saib lub ntsab lug, peb hais tias Lan-Tester yog ib tug yuav tsum rau cov neeg uas muaj feem ntau muab kev koom tes nyob rau hauv Broaching cov khub rau lub koom haum ntawm lub network kev sib txuas ntawm lub computer cov khoom.
