BNC interface yog lub txuas rau cov coaxial cable. BNC interface yog ib cov kev zam tshwj xeeb rau kev tso tawm uas txawv ntawm qhov dog dig 15-tus pin D-SUB cov khoom siv sib txuas. Nws yog tsim ntawm RGB peb thawj lub teeb liab xim thiab tsib lub teeb liab sib txuas ua ke rau kab rov tav synchronization thiab ntsug synchronization. Mas siv los txuas cov chaw txuas ua haujlwm thiab lwm qhov system uas yuav tsum tau muaj cov roj tawg ntshav ntau zaus. Q9 txuas thiab BNC muaj qhov sib txawv me me hauv qhov loj me interface, lawv muaj ntsis zoo ib yam, thiab lawv kuj tuaj yeem siv tau. Q9 yog dav siv hauv Suav teb. BNC yog tus qauv thoob ntiaj teb. Tam sim no ntau Q9s nyeg kuj tau ua raws li BNC txuj.
Qhov sib txawv ntawm Q9 taub hau thiab BNC taub hau
Q9 lub taub hau thiab BNC zoo li DB9 cov txiv neej thiab poj niam taub hau, siv rau oscilloscopes, cov tshuab hluav taws xob thiab lwm yam khoom siv. Qhov ntsuas ntsuas ntawm Q9 thiab NBC yog qhov txawv me ntsis. Qhov sib txawv nruab nrab ntawm cov poj niam txuas ntawm NBC yog me dua li ntawd Q9. Feem ntau, oscilloscope yog BNC, thiab nws tuaj yeem tso nrog Q9, tab sis nws yuav puas ntsoog yog tias nws siv sijhawm ntev. Qhov saum toj no yog txhua tus cim, them sai sai kom paub tias 50 ohms haum rau kev xa hluav taws xob, thiab 75 ohms tsim nyog rau cov cim xa khoom. Txoj kab xev digital yuav tsum yog 75 ohms.
BNC (Basic Network Card) interface yog 10Base2 txuas, uas yog, txuas coaxial nyias cable txuas. Nws tuaj yeem cais tawm cov teeb meem tawm tswv yim video, txo kev cuam tshuam ntawm lub teeb liab, thiab cov teeb liab sib kis tau loj dua li qhov zoo tib yam 15-tus pin D-hom interface, uas tuaj yeem ua tiav lub teeb liab teb zoo dua. Daim npav network ntawm qhov sib cuam tshuam tau sib xws nrog Ethernet lossis token network uas siv nyias coaxial cable raws li kev xa mus nruab nrab. Tam sim no, daim npav network ntawm hom kev sib tham no tsis tshua pom, feem ntau vim tias lub network siv nyias coaxial cable raws li cov khoom sib kis tau tsawg dua.
Tam sim no nws feem ntau siv hauv kev lag luam kev nyab xeeb saib xyuas kom xa cov cim video. Tsuas yog qee qhov ntawm cov khoom lag luam tshiab hauv cov lus tshaj 17 ntiv tes muaj qhov zoo ntawm cov kev sib tshuam. Nws cov video teeb liab tawm tswv yim kab yog tsim los ntawm R, G, B, kab rov tav theej thiab scanning ntsug. Lub tshuab txuas no tuaj yeem cais cov cim taw qhia ntawm peb tus thawj xim hauv cov yeeb yaj kiab thiab ua rau lawv nyob ywj pheej ntawm lwm tus, uas tuaj yeem zam kev cuam tshuam rau qhov loj tshaj. Kom cov yeeb yaj duab tawm tswv yim zoo dua qub. Vim li no, BNC txujci ib txwm yog ib qho ntawm cov yam ntxwv ntawm kev tshaj lij ntawm qib kev tshaj lij.
