I-topology yenethiwekhi evame ukusetshenziswa ekuqedeni isakhiwo sebhasi, ayisekeli inethiwekhi eyindilinga noma efana nenkanyezi. Yonke i-node ixhunywe nge-serial ngebhasi elilodwa kuyisinqumo esihle, esithombeni esingenhla, i-topology yenethiwekhi ejwayelekile yesistimu ye-A8-05B ibonisiwe. Ama-node e-N axhunywe kunethiwekhi enamaphuzu amaningi. Ukuze uthole isivinini esiphezulu kanye nemigqa emide, ukumelana kokuphela kuyadingeka kuzo zombili izinhlangothi zomugqa ukuze kuqedwe ukubonakaliswa. Sebenzisa ama-resistor angu-100 Ω kuzo zombili izinhlangothi (kudingeka kuphela uma ubude bentambo bungaphezu kuka-2km). Inethiwekhi kumele yakhelwe njengomugqa owodwa onezinhlayiya eziningi, hhayi njengenkanyezi. Nakuba ubude bekhebula eliphelele bungaba bufushane ekucushweni kwenkanyezi, ukuqeda okwanele akusenakwenzeka futhi ikhwalithi yesignali ingase yehle kakhulu. KuMdwebo 1 obonise okulandelayo, u-b, d, f ukuxhumana okulungile kanye no-a, c, e ukuxhumana okungalungile.
Umdwebo 1
Uma usebenzisa intambo yenethiwekhi yesivikelo (STP), kufanele ugcine ukuqhubeka kwengqimba yokuvikela ibushelelezi, bese uxhuma uMhlaba endaweni eyodwa, njengoba kuboniswe kumdwebo.
Kudingeka ucingo
Isistimu isebenzise ikhebula le-CAT-5E UTP kanye ne-STP.
Ungayikhetha kanjani ikhebula le-CAT-5E elifanelekile?
Ukumelana kwentambo ngayinye kumele kube ngu-≤35Ω uma ubude bungu-305M (ubude be-FCL).
Isiteshi somnyango esiya ku-Power Supply sisebenzise i-RVV4*0.5, ukukhiya i-RVV2*0.5 esetshenzisiwe.
Isexwayiso:
Isithombe sesiteshi somnyango ngeke siboniswe ngokugcwele esikrinini sesiteshi se-Visual Room uma isiteshi segumbi sihluke kakhulu kugesi wevidiyo, ezindaweni ezifanele ebhasini lesakhiwo ukwandisa ugesi kungaxazulula le nkinga. Ugesi wevidiyo ojwayelekile ovela esiteshini se-Visual Room sebanga eliphezulu awukwazanga ukudlula amamitha angu-30.

Sicela usebenzise i-Scotchlok ukuxhuma izintambo ezimbili
I-Scotchlok
I-UTP ne-UTP
I-UTP kanye nedivayisi akuxhunyiwe ku-inthanethi
Akuxhunyiwe ku-inthanethi futhi Akuxhunyiwe ku-inthanethi
Kudingeka nje i-jaw vice
Isithombe somphumela
Kungani ungasebenzisi i-RJ-45 ukuze uxhume?
Ngenxa yokuthi indinganiso ye-RJ-45 yenzelwe ukusetshenziswa ngaphakathi endlini kuphela, ayibi nomswakama futhi kulula kakhulu ukuyingcolisa noma ukuyingcolisa. Uma i-RJ-45 Head iphukile, kukhona ochwepheshe abanamathuluzi ochwepheshe adingekayo ukulungisa iphutha, lokhu kuzoholela ezindlekweni eziphezulu zokulungisa.
IScotchlok yilokho kanye esikudingayo. Eminyakeni engaphezu kwengu-45 eyedlule, i-3M yethule isixhumi sokuqala sokushintshashintsha kokushisa embonini - iScotchlok Connector UR. Namuhla, njengoba kunesidingo esikhulu samanethiwekhi asheshayo kanye ne-bandwidth ephezulu, uchungechunge oluphelele lwezixhumi namathuluzi e-3M luphinde lwavela. Sicela uvakashele ku-www.3M.com ukuthola ulwazi olwengeziwe lweScotchlok.
