Txawm hais tias VGA connector kuj tseem hu ua D-sub connector. Qee tus txawm hu nws DB15 connector, tab sis muaj qhov sib txawv loj ntawm lawv:
Pin kev npaj:
VGA connector pins nyob rau hauv peb kab, txhua kab muaj tsib tus pins.
DB15 connector pins nyob rau hauv ob kab, 7+8 kev sib hloov.
Pin function:
3 tus pins ntawm VGA connector yog siv los xa RGB video signals (liab, ntsuab, xiav). 2 pins yog siv rau kab rov tav synchronization teeb liab thiab ntsug synchronization teeb liab. Cov pins seem feem ntau yog siv rau hauv av thiab lwm yam kev tswj cov cim.
Cov pins ntawm DB15 connector muaj feem xyuam rau cov kev siv tshwj xeeb.
Hauv kev sib txuas VGA, DB15 pins 1 txog 3 xa cov cim liab, ntsuab, thiab xiav analog teeb liab. Pins 4 txog 8 yog cov xaim hauv av. Pins 13 thiab 14 xa cov kab ntsug thiab kab rov tav synchronization raws. Rau RS-232 daim ntawv thov kev sib txuas lus, pins yog siv rau cov ntaub ntawv xa mus thiab tswj cov teeb liab. Nyob rau hauv lub tshav pob ntawm MIDI los yog cov cuab yeej muaj, pins 1 thiab 4 yog lub luag hauj lwm rau MIDI tso zis, 2 thiab 5 yog lub luag hauj lwm rau MIDI input, 3 thiab 6 yog lub luag hauj lwm rau grounding, thiab lwm yam pins feem ntau tsis siv.
Daim ntawv thov:
Lub VGA connector yog tsim tshwj xeeb rau kev xa cov duab analog video thiab feem ntau siv hauv computer saib, projectors thiab lwm yam khoom siv video.
DB15 connector yog siv rau video signals, serial kev sib txuas lus, tshuab luam ntawv interfaces, thiab lwm yam. Nws yog feem ntau siv nyob rau hauv ntau yam khoom siv xws li VGA, suab khoom, cov ntaub ntawv kev sib txuas lus, thiab lwm yam.
