Mawaya awiriwa amatumiza zizindikiro kunja kwa gawo ndikupanga chizindikiro choyenera. Waya wina wa chizindikiro ukakhala pamagetsi okwera kwambiri poyerekeza ndi waya wolozera wa 0V, waya wachiwiriyo umakhala pamagetsi otsika, ndipo mosemphanitsa.

Kulankhulana Kwamagetsi

Kupyolera mu mauthenga otsatizana, byte ya Data imatumizidwa ngati chingwe cha ma bits asanu ndi atatu, ndikuyamba pang'ono ndi kuyimitsa pang'ono pakati. Gawo loyamba nthawi zonse limakhala 0, zomwe zikutanthauza kuti nthawi yachinthu chimodzi yangoyamba kumene. Mukamagwiritsa ntchito DMX, ma bits awiri omwe amayikidwa ku logic 1 amatchedwa "stop bits."

Powerenga kachidutswa koyambirira, mabayiti asanu ndi atatu, ndi awiriwo kumapeto, pali magawo khumi ndi amodzi. Chomwe muyenera kuchitcha ndi chimango. Chidutswa chilichonse ndi 4us kutalika chifukwa chimango chimatumizidwa nthawi 250,000 pamphindikati (nthawi zina amatchedwa 250,000 baud).

Tsatanetsatane wa DMX protocol

Protocol ya DMX imatumiza zoyambira paketi ndi mafelemu angapo pamabasi angapo. Khalidwe lomwe likuyembekezeka ndikuyambitsa paketi, kutumiza mafelemu 513, kenako ndikudikirira (osagwira ntchito) kwakanthawi musanayambe ntchitoyi. Kumbukirani kuti si onse olamulira a DMX omwe angathe kutumiza mafelemu 513 monga momwe zilili.

Mayendedwe a DMX

Pamlingo wake wofunikira kwambiri, DMX-512 ndi gulu la ma data omwe amatchedwa "channel." Mawu akuti "chilengedwe" nthawi zina amagwiritsidwa ntchito kufotokoza njira zonsezi. Makanema onse mu "Chilengedwe" amafika pa 512. Njira iliyonse yakhala nyenyezi yosiyana mu mlalang'amba. Koma m'makina amakono owunikira omwe ali ndi zida zovuta kwambiri, njira iliyonse ya DMX nthawi zambiri imalumikizidwa ndi gawo lina lazowunikira zokha.

Njira iliyonse ikhoza kukhala ndi mtengo pakati pa 0 ndi 255. Choyamba, DMX-512 inapangidwa kuti iziyang'anira ma dimmers ofunikira kwambiri, kotero kuti ma 0-255 amtundu uliwonse adagwiritsidwa ntchito poyang'anira kutuluka kwa kuwala kuchokera ku 0-255. Mwanjira imeneyi, wogwiritsa ntchito amatha kusintha momwe kuwala kwamagetsi kumakhalira. Makanema a DMX tsopano amagwiritsidwa ntchito kuwongolera zinthu monga kuwala, poto, ndi kupendekeka pamagetsi opangira magetsi ndi zida zina zosangalatsa.

Chilengedwe chimodzi cha DMX chitha kuganiziridwa ngati gulu la mayendedwe 512. Chilengedwe chilichonse cha DMX chikhoza kukhala ndi chimodzi mwazinthu 256 zomwe zingatheke (255 Plus 1 kwa 0).

Kuwongolera kuyatsa pogwiritsa ntchito njira

Mtundu uliwonse wa zowunikira zodzichitira zokha uyenera kukhala ndi gawo linalake la chilengedwe cha DMX lopatulidwira ilo. Ndi mayendedwe osiyanasiyanawa, mutha kusintha gawo lililonse la nyali (nthawi zambiri pakati pa 12 ndi 30). Kuwala kumayendetsedwa ndi njira imodzi ya DMX system, pomwe poto ndi mapendedwe amayendetsedwa ndi njira ziwiri ndi zitatu, motsatana. 

Kuwala kulikonse kumakhala ndi adilesi yakeyake ya DMX, yomwe imatiuza njira mu chilengedwe cha DMX yomwe idzayambe kulandira malamulo. Zosankha zamkati zazomwe zimachitika nthawi zambiri zimagwiritsidwa ntchito kusintha adilesi yoyambira ya DMX.

Wogwiritsa ntchito amayenera "kuyika" chowunikira chowunikira kuti apatse chida chilichonse adilesi yapadera ya DMX. Tsopano kuti console ndi magetsi amatha kulankhulana wina ndi mzake, mitundu yonse yamatsenga ikhoza kuchitika. The console coder imatha kusankha kuwala, kusintha zina mwazosintha zake, ndikusunga zosintha. 

Ngakhale kutulutsa kwa kontrakitala nthawi zambiri kumawonetsa zidziwitso zomveka bwino pamikhalidwe yowerengeka ndi anthu pazinthu monga mtundu, mphamvu, malo, ndi zina zambiri, manambalawa nthawi zonse amamasulira kumagulu amtundu wa DMX ndi zomwe amafanana.

DMX-512 ndiyofunika kuti mulankhule ndi magetsi chifukwa imatumiza deta yofunika yolamulira. Mpaka m'malo mwa protocol ya DMX-512 itapangidwa, ndikofunikira kuti aliyense amene amagwira ntchito yowunikira adziwe momwe DMX-512 imagwiritsidwira ntchito pamakampani.

Gawo la Hardware

Chifukwa chowunikiracho chili kutali ndi siteji, DMX512 imagwiritsidwa ntchito nthawi zambiri pamtunda wautali. Kukakhala phokoso lamagetsi mozungulira, chizindikiro chimapita kutali ngati chinganyamulidwe kutali. Izi, komanso kuti DMX imagwiritsidwa ntchito nthawi zambiri m'malo okhala ndi phokoso lamagetsi. Ichi ndichifukwa chake RS-485 idasankhidwa kukhala protocol yabwino kwambiri.

Kuti mudziwe zomwe zizindikirozi zikutanthawuza, muyenera kudziwa kusiyana pakati pa waya wa data (D +) ndi waya wa data (D-) (D-). Timatcha ichi "chizindikiro chosiyana" chifukwa tikuyesa kusiyana. Kotero kuti kusiyana pakati pa zizindikiro ziwiri kumakhalabe chimodzimodzi. 

Zizindikiro zosiyana ngati RS485 zimakonda kumveka phokoso lofanana ndi mizere yonse iwiri. Potha kusiyanitsa pakati pa zizindikiro ziwirizi, kulankhulana kwakutali kumatheka. Muyezo wa DMX umati kuthamanga kwakutali kuyenera kukhala kosapitilira 1,000 mapazi, koma RS-485 idavotera mapazi 4,000.

Ngakhale zambiri za DMX zimatumizidwa pazingwe za XLR-5, zingwe za XLR-3 zothandizidwa ndi DMX zimagwiritsidwanso ntchito. Kwa RS-485, mumangofunika mizere itatu: nthaka, Data+, ndi Data-. Mizere itatu imeneyo nthawi zambiri inali yonse yomwe imagwiritsidwa ntchito. Kukonzekera kukula kwamtsogolo, mizere yowonjezera ya deta inayenera kuwonjezeredwa, kotero chingwe cha XLR-5 chinapangidwa.

Mapangidwe a paketi

Asynchronous serial data popanda kufanana ndi ma bits stop awiri amatumizidwa ngati data ya DMX pa 250 kbit/s. Kotero, pang'ono kapena kuyika kwa wotchi kumatenga masekondi anayi kutumiza. Mapangidwe a paketi ndi abwino, ndipo amayamba ndi BREAK yayitali pomwe Data yaphokoso yokha imatumizidwa.

Pachimake chotsatira chimatchedwa Mark After Break, chomwe chimangokhala kanthawi kochepa (MAB). Chotsatira ndi Start Code (SC), yomwe imatumizidwa ngati 11-bit serial frame ndi mtengo wa 0x00 monga deta. Pali pang'ono pang'ono, baiti imodzi ya data yokhala ndi ma bits asanu ndi atatu, ndi ma bits awiri okwera. Zambiri mu Start Code zitha kuwonetsanso mtundu wamtundu wa DMX womwe uli mu paketi.

Start Code 0x17 imasonyeza paketi ya malemba, pamene Start Code 0xCC imasonyeza paketi Yoyang'anira Chida Chakutali. Pambuyo pa Start Code, zina zonse za DMX zimatumizidwa mu mafelemu 512 omwe ali ofanana. Mafelemu awa amatchedwa ma SLOTs (mitengo ya RGB, makonda a CMY, malo a servo, kuthamanga kwa makina a chifunga, ndi zina ...).

Kodi zabwino ndi zoyipa za DMX512 ndi ziti?

Kukonzekera kwa DMX kungakhale kothandiza nthawi zambiri. Zitha kupanga kusiyana kwakukulu pamawonekedwe anu owunikira, koma zilinso ndi zoletsa zingapo.

Limodzi mwamavuto ndi DMX ndikuti imafunikira ma waya ambiri. Mawaya ochulukirapo amatenga nthawi yochulukirapo kuti akhazikike. Zimatenga nthawi yochulukirapo kukonzekera ziwonetsero zapadera zowunikira pasadakhale. Zimatenganso nthawi yochulukirapo kusintha magetsi pazochitikazo, zomwe zingakhale zovuta. Mungafunike anthu ochulukirapo kuti ayendetse machitidwe owunikira, choncho kumbukirani izi popanga bajeti.

Pali mwayi woti katsatidwe ka mawu ndi kuwala komwe kumabwera ndi chipangizocho. Makonzedwe a phokoso ndi kuwala atha kuwoneka bwino kuposa chilichonse chomwe mungadzipangire nokha. DMX singagwiritsidwe ntchito kuwongolera magetsi omwe sali abwino.

Chimodzi mwazabwino zambiri za DMX ndikuti imagwira ntchito ndi mitundu yosiyanasiyana yamitundu ndi mitundu, kotero mutha kuwakonza onse kuti achite zomwezo. Mutha kusinthana ndi zomwe zidachitika kale, zomwe nthawi zambiri sizinapangidwe bwino. Mapangidwe omwe amabwera ndi zida zina zowunikira nokha kuti chipindacho chiwoneke bwino ndikugwiritsa ntchito magetsi m'njira zambiri. Mitu yosuntha kapena makina ojambulira amatha kupanga zowunikira zomwe zitha kuloza mwanjira inayake.

Kuti zikhale zosavuta kuwongolera magetsi, amapita ndi nyimbo pamene nyimbo yogunda pang'onopang'ono ikuyamba, ndipo mapulogalamu ambiri omwe amabwera ndi makompyuta amaundana, kutha kufananiza mayendedwe a nyimbo kapena sewero ndi chiwonetsero chopepuka. Kutsegula strobing kumayambiriro kwa nyimbo ndi njira yabwino kwambiri yowonjezeretsa chiwonetsero cha anthu.

Zithunzi za Art-Net

Art-Net ndi njira yolumikizirana yaulere. Artnet imatumiza protocol ya DMX512-A yowongolera kuyatsa ndi protocol ya Remote Device Management (RDM) pa intaneti pogwiritsa ntchito UDP.

Protocol ya Art-Net ndikukhazikitsa kosavuta kwa protocol ya DMX512-A pa UDP ndipo imagwiritsidwa ntchito pamaneti amdera lanu ngati Ethernet. Amagwiritsidwa ntchito kutumiza deta yowunikira magetsi pamaneti. Ma Node amatha "kulembetsa" ku node za "ofalitsa", kotero ma node A ndi B amatha kulembetsa ku node C, mwachitsanzo. Zina zowongolera zimaphatikizapo kupeza ma node, kukonzanso magawo owongolera ma node, ndi kutumiza ma timecode. Ndizothekanso kutumiza ndi kulandira zambiri za magetsi (C idzakhala chidziwitso cha unicast ku A ndi B).
