Cov qauv network topology feem ntau siv qhov xaus ntawm cov qauv tsheb npav, tsis txhawb nqa lub network puag ncig lossis lub hnub qub. Txhua lub node yog txuas nrog serial los ntawm ib lub tsheb npav yog qhov kev xaiv zoo, hauv daim duab saum toj no, cov qauv network topology ntawm A8-05B system tau qhia. N nodes txuas nrog hauv lub network ntau lub ntsiab lus. Rau qhov ceev dua thiab cov kab ntev dua, qhov kev tiv thaiv xaus yog qhov tsim nyog ntawm ob qho kawg ntawm kab kom tshem tawm cov kev cuam tshuam. Siv 100 Ω resistors ntawm ob qho kawg (xav tau tsuas yog tias qhov ntev ntawm cov xov hlau > 2km). Lub network yuav tsum tau tsim ua ib kab nrog ntau qhov poob, tsis yog ua lub hnub qub. Txawm hais tias tag nrho qhov ntev ntawm cov xov hlau tej zaum yuav luv dua hauv kev teeb tsa hnub qub, qhov kev xaus txaus tsis tuaj yeem ua tau lawm thiab qhov zoo ntawm lub teeb liab yuav poob qis heev. Hauv Daim Duab 1 uas tau qhia tom ntej, b, d, f yog qhov txuas zoo thiab a, c, e yog qhov txuas tsis raug.
Daim Duab 1
Thaum siv cov xov hlau tiv thaiv network (STP), Yuav tsum tswj kom qhov txuas ntxiv ntawm cov txheej tiv thaiv du, thiab txuas lub ntiaj teb ntawm ib qho taw tes, raws li qhia hauv daim duab
Yuav tsum tau siv hlau
Lub kaw lus siv CAT-5E UTP thiab STP cable.
Yuav ua li cas xaiv cov kab CAT-5E uas tsim nyog?
Qhov tsis kam ntawm txhua txoj hlau yuav tsum ≤35Ω thaum ntev yog li 305M (FCL ntev).
Qhov rooj rau qhov chaw muab hluav taws xob siv RVV4 * 0.5, kom xauv siv RVV2 * 0.5.
Ceeb Toom:
Daim duab ntawm qhov rooj yuav tsis pom tag nrho hauv Visual Room-station lub vijtsam thaum Chav-station txawv ntawm lub hwj chim video, ntawm qhov chaw tsim nyog hauv lub tsev kom nce lub hwj chim tuaj yeem daws qhov teeb meem no. Lub hwj chim video dav dav los ntawm chav-station pom ntawm qhov deb tshaj plaws yuav tsis pub tshaj 30 meters.

Vim li cas ho tsis siv RJ-45 rau kev sib txuas?
Vim tias tus qauv RJ-45 tsuas yog siv rau hauv tsev xwb, nws tsis tiv taus dej noo thiab yooj yim ua qias neeg lossis oxidized. Yog tias lub taub hau RJ-45 tawg, muaj cov kws tshaj lij tuav cov cuab yeej tshaj lij uas xav tau los kho qhov txhaum, qhov no yuav ua rau cov nqi kho dua siab dua.
Scotchlok yog qhov peb xav tau tiag tiag. Tshaj 45 xyoo dhau los, 3M tau qhia txog kev lag luam thawj qhov insulation displacement connector - Scotchlok Connector UR. Niaj hnub no, nrog rau kev thov ntau ntxiv rau cov tes hauj lwm ceev ceev thiab high-bandwidth, tag nrho cov koob ntawm 3M connectors thiab cov cuab yeej tau hloov zuj zus dua. Thov mus saib www.3M.com kom paub ntau ntxiv txog Scotchlok.
