Tshaj tawm DMX512 lub teeb teeb liab, tus yam ntxwv impedance 120Ω, siv cov khoom zoo thiab siab dawb paug (OFC) oxygen-dawb tinned tooj liab hlau tso tseg; tshwj xeeb yog tsim los ntawm polyethylene rwb thaiv tsev, 2 cores twisted, aluminium foil ntxiv rau tinned tooj liab hlau nrog 95% kev pab cuam Braided ob-txheej shielding, lub sheath yog tsim los ntawm tshwj xeeb formulated PVC khoom, thiab cov pa sheath yog dub.
DMX512 yog cov txheej txheem dimming, uas tuaj yeem siv rau digitally tswj dimmers thiab lwm yam khoom siv tswj hauv qhov chaw xws li theem, ua yeeb yam, studios, thiab lwm yam. Nws yog qhov tsim nyog rau ntau lub ntsiab lus tus tswv- qhev tswj qhov system, thiab nws cov kev sib tshuam hauv daim ntawv. txais cov qauv tsheb npav ntau lub ntsiab lus, tsis muaj cov ntaub ntawv channel thaiv teeb meem, nws txoj kev sib txuas yog yooj yim, thiab kev ntseeg siab yog siab.
Cov kev cai ntawm DMX512 cov ntaub ntawv kis tus nqi thiab cov yam ntxwv decentralized ntawm kev tswj network. Lub cev txheej txheej yog tsim los nrog RS-485 lub tsheb npav transceivers, thiab lub tsheb npav siv ib tug khub ntawm twisted-pair xov hlau kom paub txog kev sib txuas ntawm lub dimmer thiab lub dimmer. Lub tsheb npav RS-485 txais kev sib npaug sib kis thiab kev txais tos sib txawv, nrog kev txais siab thiab muaj peev xwm tiv thaiv kev cuam tshuam. Lub teeb liab kis tau tus mob mus txog 1000m. Yog hais tias lub dimmer nyob deb dhau ntawm lub dimmer, lub amplifier lossis teeb liab splitter tuaj yeem siv los txhim kho lub teeb liab. DMX512 raws tu qauv siv lub tsheb npav-hom qauv, tab sis cov ntaub ntawv yog kis unidirectionally los ntawm lub dimmer mus rau lub dimmer, yog li tsis muaj qhov tshwm sim ntawm cov ntaub ntawv thaiv los ntawm kev sib tw ntawm cov dimmers rau txoj cai siv lub tsheb npav.
