1. Chiyambi cha DMX

DMX (Digital Multiplexing) ndiye msana wamasitepe amakono komanso zowongolera zowunikira. Kuchokera ku zosowa za malo owonetserako zisudzo, zimathandiza wolamulira mmodzi kutumiza malamulo olondola kwa mazana a ma spotlights, makina a chifunga, ma LED, ndi mitu yosuntha nthawi imodzi. Mosiyana ndi ma dimmers osavuta a analogi, DMX imalumikizana ndi "mapaketi" adijito, zomwe zimathandiza opanga kusinthiratu mitundu yovuta, ma strobe, ndi zotsatira zofananira.

2. Mbiri Yachidule ya DMX

DMX idatulukira pakati pa zaka za m'ma 1980 pamene makampaniwa ankafuna kusintha ndondomeko zosagwirizana ndi analogi. Muyezo wa 1986 DMX512 udatanthauzira kufalikira kwa mayendedwe a data 512 pa chingwe chotchinga, ndikukhazikitsa kulumikizana pakati pa mitundu ndi zida. Ngakhale kuti pali ma protocol atsopano, DMX512 idakali yogwiritsidwa ntchito kwambiri ndipo imayamikiridwa kwambiri chifukwa cha kuphweka kwake, kudalirika, ndi nthawi yeniyeni.

3.Core Zigawo za DMX Systems

 3.1 DMX Wowongolera

 "Ubongo" wa zida zanu:

• Hardware console: Gulu lowongolera thupi lomwe lili ndi ma fader ndi mabatani.

• Software Interface: Pulogalamu ya pakompyuta kapena piritsi yomwe imayika ma tchanelo kupita ku masilayidi.

• Zida Zophatikiza: Zimaphatikiza chowongolera chophatikizika ndi chotulutsa cha USB kapena Ethernet.

 3.2 DMX Cables ndi Zolumikizira

Kutumiza kwamtundu wapamwamba kumafunika:

• Chingwe cha 5-pin XLR: Uwu ndiye mulingo wovomerezeka, koma zingwe za 3-pin XLR zimagwiritsidwa ntchito nthawi zambiri bajeti ikavuta.

• Splitters ndi Booster: Gawani chizindikiro pazingwe zingapo popanda kutsika kwamagetsi.

• Terminator: 120 Ω resistor kumapeto kwa chingwe kumalepheretsa kuwunikira kwa siginecha.

 3.3 Zosintha ndi Ma Decoder

 Kuunikira ndi zotsatira zimalumikizana kudzera pa DMX:

• Zosintha zokhala ndi zolumikizira za DMX zophatikizika: Mitu yosuntha, ma PAR, mizere ya LED.
• Ma Decoder Akunja: Sinthani data ya DMX kukhala PWM kapena voteji ya analogi kuti mugwiritse ntchito ndi mizere, machubu, kapena zosintha mwamakonda.
• UXL Tags: Zida zina zimathandizira DMX opanda zingwe, zomwe zimafuna gawo la transceiver m'malo mwa zingwe.

4.Momwe DMX Amalumikizirana

4.1 Mawonekedwe a Signal ndi Makanema

DMX imatumiza deta m'mapaketi ofika ku 513 byte:

1. Khodi Yoyambira (1 byte): Ziro nthawi zonse pazosintha wamba.

2. Channel Data (512 byte): Bite iliyonse (0-255) imatsimikizira kukula, mtundu, poto / kupendekera, kapena kuthamanga kwake.

Chipangizo chilichonse chimalandira tchanelo chomwe chapatsidwa ndikuyankha kutengera mtengo wa byte yomwe walandilidwa.

  4.2 Ma adilesi ndi Universes

1. Gulu la tchanelo lili ndi ma tchanelo 512.

2. Pakuyika kokulirapo, magulu angapo amakanema amatha kumangidwa unyolo kapena kutumizidwa kudzera pa Ethernet (kudzera pa Art-NET kapena sACN).

3. Adilesi ya DMX: Nambala yoyambira ya tchanelo - izi ndizofunikira kuletsa zosintha ziwiri kugwiritsa ntchito deta yomweyo.

5.Kukhazikitsa Basic DMX Network

5.1 Konzani Mapangidwe Anu

1. Kupereka Zokonzekera: Jambulani mapu osalongosoka a malowo ndikulembani gulu lililonse ndi adilesi yake ya DMX ndi nambala ya tchanelo.

2. Kuwerengetsera Utali Wachingwe: Tsatirani kutalika kwa chingwe (nthawi zambiri mamita 300).

5.2 Maupangiri Opangira Wiring ndi Njira Zabwino Kwambiri

1. Daisy Chain: Sinthani zingwe kuchokera ku controller kupita ku china kupita ku china mpaka choletsa choletsa.

2. Kutchinga: Pewani kulumikiza zingwe ndikuzisunga kutali ndi zingwe zamagetsi kuti muchepetse kusokoneza.

3. Lembani Zingwe Zonse: Lembani mapeto onse a chingwe chilichonse ndi nambala ya tchanelo ndi njira yoyambira.

5.3 Kusintha Koyamba

1. Kupereka Maadiresi: Gwiritsani ntchito menyu ya chipangizocho kapena masiwichi a DIP.

2. Kuyesa Kwamphamvu: Pang'onopang'ono onjezerani kuwala kwa wowongolera kuti muwonetsetse kuyankha koyenera.

3. Kuthetsa Mavuto: Ngati chipangizo sichikuyankhidwa, sinthanani mapeto a chingwe, yang'anani zotsutsa zoyimitsa, ndikutsimikizirani ntchito ya tchanelo.

6. Ntchito Zothandiza za DMX

1. Ma Concerts ndi Zikondwerero: Gwirizanitsani kuyatsa kwa siteji, zojambula zoyenda, ndi zowombera moto ndi nyimbo.

2. Zopanga Zisudzo: Pulogalamu ya Pre-Programme imazilala mosawoneka bwino, ma siginecha amitundu, ndi kutsata kwakuda.

3. Zowunikira Zomangamanga: Onjezani mphamvu pomanga ma facade, milatho, kapena kukhazikitsa zaluso zapagulu.

4. Tradeshows: Gwiritsani ntchito ma gradients osinthika amitundu ndi ma siginecha adontho kuti muwonetsere nyumba yanu.

7.Kuthetsa Mavuto Odziwika a DMX

1. Zipangizo zoyambukira: Nthawi zambiri zimachitika chifukwa cha chingwe chosokonekera kapena kusowa kolumikizira.

2. Zipangizo zosagwira ntchito: Yang'anani ngati pali zolakwika kapena kusintha chingwe cholakwika.

3. Kuwongolera kwakanthawi: Chenjerani ndi kusokonezedwa ndi ma elekitiroma - tumizaninso zingwe kapena kuwonjezera mikanda ya ferrite.

4. Kugawa mochulukira: Ngati zida zopitilira 32 zigawana malo amodzi, gwiritsani ntchito wogawa.

8.Njira Zapamwamba ndi Mapulogalamu Opangira

1. Mapu a Pixel: Gwiritsani ntchito LED iliyonse ngati njira yosiyana kuti mujambule kanema kapena makanema apakhoma.

2. Kulunzanitsa kwa Timecode: Lumikizani zolemba za DMX kuti musewere nyimbo kapena makanema (MIDI/SMPTE) kuti muzichita bwino nthawi yake.

3. Kuwongolera kogwiritsa ntchito: Phatikizani masensa oyenda kapena zoyambitsa zoyambitsa omvera kuti kuyatsa kuphatikizepo.

4. Kupanga mawaya opanda zingwe: Pamalo omwe zingwe zilibe mphamvu, gwiritsani ntchito ma Wi-Fi kapena makina a RF-DMX.
