DB connectors, uas yog D-hom data interface connectors, muab faib ua txiv neej thiab poj niam interfaces, thiab yog dav siv nyob rau hauv computers, saib, printers thiab lwm yam khoom. Nyob rau hauv kev lag luam connector, nws muaj npe raws li tus naj npawb ntawm pins nyob rau hauv lub interface. Piv txwv li, 9 tus pins feem ntau yog hu ua DB9, VGA interface yog hu ua DB15, thiab qhov chaw sib txuas uas feem ntau siv hauv kev lag luam tshuab luam ntawv hu ua DB25.
DB connector khoom taw qhia (DB9 ua piv txwv):
DB9 muaj tag nrho ntawm 9 tus pins, tseem hu ua 9PIN hauv kev lag luam txuas. Nws yog ib qho txuas me me hauv DB series, thiab nws kuj yog qhov chaw nres nkoj serial. Feem ntau peb muaj ntau dua ntawm cov khoos phis tawj, thiab DB9 connector interface yeej ib txwm tau tseg rau ntawm lub khoos phis tawj motherboard. Muaj ob hom DB9 connectors, feem ntau yog txiv neej thiab poj niam pob qij txha. Cov uas muaj pins feem ntau yog DB9 txiv neej, thiab cov uas muaj qhov yog DB9 poj niam. DB9 feem ntau yog tsau ntawm lub khoos phis tawj motherboard thiab saib cov teeb liab input interface. Cov kab siv los txuas lub khoos phis tawj teeb liab qhov chaw thiab cov teeb liab saib tau txais qhov kawg yog DB txuas kab, tseem hu ua kab video.
Cov ntaub ntawv cable uas txuas lub computer mus rau lub saib lossis lwm yam khoom siv sab nraud yog cov ntaub ntawv cable nrog txiv neej thiab poj niam DB9 txuas ntawm ob qho kawg, uas feem ntau hu ua video cable lossis VGA cable. VGA cov ntaub ntawv kab tsis yog ib qho kev ruaj khov. Qhov ntev ntawm VGA cov ntaub ntawv kab feem ntau yog kho, xws li 50CM, 1M, 4M thiab lwm yam.
