Lan-magwajin: description, nadi

Lan-magwajin - wani kayan tsara don duba mutunci sadarwa networks. Yawanci, irin wannan na'urar qunshi wani babban bangare kuma wani m (yawanci daya, amma akwai model a wanda wani jam'i na m rabo da aka bayar). Lan-magwajin damar "prozvanivat" kwamfuta cibiyar sadarwa, tarho da ãyõyinMu, matsawa haɗawar.

Cibiyar sadarwa Gwaji ƙwarai facilitates aikin da kuma kubutar da lokaci kwararru na USB aiki. Bayan duk, su aiki ne ba kawai ga broach sadarwa, amma kuma a cire kuskure dukan tsarin. Gani, shi ne kusan ba zai yiwu ba domin sanin ingancin da crimp connector, kuma zuwa ga zobe fita da wani magwajin, zai dauki lokaci mai tsawo da kuma mataimaki. Dannawa da Twisted biyu ne ba ko da yaushe a cikin wannan dakin, sau da yawa da iyakar da waya ne a daban-daban bangarorin ginin da kuma a kan daban-daban benaye, da kuma "ci gaba" a cikin wannan harka a multimeter zai zama fuskantar da kuma m. Wannan inda muka zo a cikin m taimakon da irin wannan na'urar a matsayin Lan-magwajin.

Domin da "ci gaba" damfara masu haɗin a duka biyu na ƙyallen maƙalawa a Twisted biyu. Sa daya karshen cikin manyan jiki na magwajin connector, da kuma na biyu - mai ciruwa connector part. Bayan haka, muna kunna na'urar da gudu da shi a cikin gwajin yanayin. Godiya ga LED nuni, Lan-magwajin domin sanin ba kawai gaban karya na Twisted biyu wayoyi da kuma gajarta da'ira, amma kuma ya samu garwaya wayoyi.

Sau da yawa sosai, sabon shiga sakaci dubawa crimp haɗawar. Fara "prozvanivat" kawai idan kwamfuta cibiyar sadarwa ba ya aiki. Duk da haka, wannan gwajin dole ne a da za'ayi a kowane crimp connector don tabbatar da daidaito da kuma mutuncin dangane da connector fil, ba kawai waɗanda suke a halin yanzu a cikin yin amfani da kwamfuta na cibiyar sadarwa. In ba haka ba ba za ka iya hana gaba kurakurai da kuma tsarin hadarurruka.

Akwai babbar selection na cibiyar sadarwa testers, duka mai son da kuma sana'a. A dunƙule dai, ina so in bayyana amfanin sana'a kayan.

Irin wannan na'urorin ya iya gwada ba kawai Twisted-biyu, amma kuma tarho coaxial igiyoyi. Professional lan-magwajin (USB) kuma da misali gwajin aka bayyana a sama za a iya auna tsawon, don en, da sigina na sauti, kuma sigina gaban aiki conductors. Irin wannan na'urorin da high-sa nuni, wanda nuna duk dole bayanai a kan USB yanayin. Kuma mafi muhimmanci, wadannan na'urorin da babban yawan m kayayyaki. Alal misali, lokacin da ja da igiyoyi ta hanyar kabelgony "networkers" sukan fuskanci matsalar ganewa na "kansa" na USB. Hoto game da wannan: garkuwar mai danko da iyakar Twisted nau'i-nau'i 10-15, da kuma shi ne kawai zai yiwu ba ga fahimta wanda daya ne "naku".

"Ci" mai son magwajin iya ja a kan na dogon lokaci, musamman idan wasu karshen ne a cikin wancan gefe na ginin. A irin wannan halin da ake ciki zai taimaka m kayayyaki masu sana'a na'urar. Za ka iya sa a kan kowane karshen da a koyaushe, kuma kansu a karo na biyu da ƙarshen USB ta wajen main naúrar magwajin yin lissafi da ake bukata waya.

A takaice, mu ce Lan-Gwaji ne dole ne ga mutanen da suke sau da yawa da hannu a broaching Twisted biyu ga kungiyar na cibiyar sadarwa sadarwa na kwamfuta kayan aiki.
