DMX (Digital Multiplex) yog cov txheej txheem kev sib txuas lus digital rau kev tswj cov theem teeb pom kev zoo thiab lwm yam khoom siv, hu ua DMX512. Nws tau tsim los ntawm United States Institute of Theatrical Technology (USITT) thiab tau pib siv los tswj theem teeb pom kev zoo. Niaj hnub no, nws yog dav siv nyob rau hauv theem, concerts, theaters, architectural teeb pom kev zoo, thiab lwm yam sij hawm.
Nov yog qee qhov tseem ceeb ntawm DMX:
1. Multi-channel tswj: DMX512 raws tu qauv tso cai rau mus txog 512 txoj kev ywj pheej tswj ib txhij los ntawm ib tug tib cov ntaub ntawv kab, txhua channel coj mus rau ib tug ntaus ntawv los yog ib tug tej yam cwj pwm ntawm lub ntaus ntawv (xws li brightness, xim, txav, thiab lwm yam. . ntawm lub teeb).
2. Cov cuab yeej siv tau zoo: DMX cov teeb liab tuaj yeem txuas mus rau ntau yam khoom siv sib txawv, suav nrog theem teeb, pos huab, lasers, thiab lub teeb txav, tso cai rau cov neeg ua haujlwm tswj hwm hauv nruab nrab ntawm ntau yam khoom siv.
3. Txoj kev sib kis: DMX feem ntau yog siv XLR interface (3-pin lossis 5-pin) los xa cov teeb liab thiab nthuav tawm ntawm cov khoom siv hauv daim ntawv ntawm cov ntaub ntawv serial, kom ntseeg tau ceev thiab raug tswj cov teeb liab kis tau tus mob.
4. Kev tswj lub sijhawm tiag tiag: DMX tso cai rau cov neeg tsim teeb pom kev zoo los kho thiab tswj cov cuab yeej hauv lub sijhawm, yog li nws tau siv dav hauv kev ua yeeb yam, concerts thiab ua yeeb yam.
5. Terminal tsis kam: A 120-ohm davhlau ya nyob twg resistor feem ntau yuav tsum tau txuas nrog lub cuab yeej kawg hauv DMX512 system kom tsis txhob muaj teeb meem cuam tshuam thiab cov ntaub ntawv tsis raug.
Feem ntau, DMX512 yog tus qauv thiab txhim khu kev qha digital tswj raws tu qauv hauv thaj chaw ntawm theem, kev ua yeeb yam, teeb pom kev zoo vaj tsev, thiab lwm yam, uas tuaj yeem tswj tau zoo thiab synchronize ntau yam teeb pom kev zoo thiab cov khoom siv tshwj xeeb.
