1. Chiyambi cha DMX

DMX (Digital Multiplexing) ndiye maziko a kuwongolera kwamakono kwa magetsi pa siteji ndi zomangamanga. Potengera zosowa za malo owonetsera zisudzo, imalola wowongolera m'modzi kutumiza malamulo olondola ku mazana ambiri a ma lightlights, makina a chifunga, ma LED, ndi mitu yoyenda nthawi imodzi. Mosiyana ndi ma analog dimmers osavuta, DMX imalumikizana mu "mapaketi" a digito, zomwe zimathandiza opanga kusintha mitundu molunjika, mawonekedwe a strobe, ndi zotsatira zofananira.

2. Mbiri Yachidule ya DMX

DMX idayamba pakati pa zaka za m'ma 1980 pamene makampaniwa ankafuna kusintha ma protocol a analog osasinthasintha. Muyezo wa 1986 DMX512 unafotokoza momwe ma data channels okwana 512 amafalitsidwira kudzera pa chingwe chotetezedwa, zomwe zinapangitsa kuti kulumikizana pakati pa makampani ndi zipangizo kukhale kofanana. Ngakhale kuti pali ma protocol atsopano, DMX512 ikadali yogwiritsidwa ntchito kwambiri ndipo imalemekezedwa kwambiri chifukwa cha kuphweka kwake, kudalirika, komanso kugwira ntchito nthawi yeniyeni.

3. Zigawo Zazikulu za Machitidwe a DMX

 3.1 DMX Controller

 "Ubongo" wa zida zanu:

• Chokonezera cha Hardware: Chowongolera chenicheni chokhala ndi ma fader ndi mabatani.

• Chiyanjano cha Mapulogalamu: Pulogalamu ya PC kapena piritsi yomwe imalumikiza njira ndi ma slider.

• Zipangizo Zosakanikirana: Zimaphatikiza chowongolera cholumikizidwa ndi USB kapena Ethernet output.

 3.2 Zingwe za DMX ndi Zolumikizira

Kutumiza deta kwapamwamba kumafuna:

• Chingwe cha XLR cha ma pin 5: Ichi ndiye muyezo wovomerezeka, koma ma pin 3 a XLR nthawi zambiri amagwiritsidwa ntchito ngati bajeti ili yochepa.

• Zogawanika ndi Zowonjezera: Gawani chizindikirocho pazingwe zingapo popanda kutsika kwa magetsi.

• Terminator: Chotsutsa cha 120 Ω kumapeto kwa chingwe chimaletsa kuwunikira kwa chizindikiro.

 3.3 Zokonzera ndi Zochotsera

 Kuwala ndi zotsatira zake zimalumikizana kudzera pa DMX:

• Zolumikizira zokhala ndi zolumikizira za DMX zolumikizidwa: Mitu yoyenda, ma PAR, mizere ya LED.
• Ma Decoders Akunja: Sinthani deta ya DMX kukhala PWM kapena voltage ya analog kuti mugwiritse ntchito ndi mizere, machubu, kapena zida zapadera.
• Ma tag a UXL: Zipangizo zina zimathandizira DMX yopanda zingwe, zomwe zimafuna gawo la transceiver m'malo mwa zingwe.

4. Momwe DMX Amalankhulirana

4.1 Kapangidwe ka Zizindikiro ndi Ma Channel

DMX imatumiza deta m'mapaketi a ma byte okwana 513:

1. Khodi Yoyambira (byte imodzi): Nthawi zonse zero pamakina okhazikika.

2. Deta ya Channel (mabaiti 512): Baiti iliyonse (0-255) imatsimikiza mphamvu, mtundu, kupendekera/kupendekera, kapena liwiro la zotsatira.

Chipangizo chilichonse chimalandira njira yake yoperekedwa ndipo chimayankha kutengera mtengo wa byte yolandiridwa.

  4.2 Kulankhulana ndi Ma Universe

1. Gulu la njira limapangidwa ndi njira 512.

2. Pa makonzedwe akuluakulu, magulu angapo a njira amatha kumangidwa ndi unyolo kapena kutumizidwa kudzera pa Ethernet (kudzera pa Art-NET kapena sACN).

3. Adilesi ya DMX: Nambala yoyambira ya chipangizo cholumikizira - izi ndizofunikira kuti zingwe ziwiri zisagwiritse ntchito deta yomweyo.

5. Kukhazikitsa Netiweki Yoyambira ya DMX

5.1 Kukonzekera Kapangidwe Kanu

1. Kugawa Masewera: Jambulani mapu ozungulira a malo ochitira masewerawa ndipo lembani mayina a DMX adilesi ndi nambala yake ya njira.

2. Kuwerengera Utali wa Chingwe: Tsatirani kutalika konse kwa chingwe komwe kumalimbikitsidwa (nthawi zambiri mamita 300).

5.2 Malangizo Olumikizira Mawaya ndi Njira Zabwino Kwambiri

1. Daisy Chain: Tulutsani zingwe kuchokera pa chowongolera kupita ku cholumikizira china kupita ku cholumikizira china kupita ku choletsa choletsa.

2. Kuteteza: Pewani kumangirira zingwe ndipo zisungeni kutali ndi zingwe zamagetsi kuti muchepetse kusokoneza.

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

5.3 Kakonzedwe Koyamba

1. Kugawa Ma Adilesi: Gwiritsani ntchito menyu ya chipangizocho kapena ma switch a DIP.

2. Mayeso Ogwiritsa Ntchito Mphamvu: Pang'onopang'ono onjezerani kuwala kwa chowongolera kuti muwonetsetse kuti chayankha moyenera.

3. Kuthetsa Mavuto: Ngati chipangizo sichikugwira ntchito, sinthani malekezero a chingwe, yang'anani zoletsa zomaliza, ndikutsimikizira momwe njirayo yagwiritsidwira ntchito.

6. Kugwiritsa Ntchito Mwanzeru kwa DMX

1. Makonsati ndi Zikondwerero: Konzani magetsi a pa siteji, zithunzi zoyenda, ndi zozimitsa moto ndi nyimbo.

2. Zopanga Zasewero: Kuzimiririka pang'ono kwa pulogalamu isanayambe, zizindikiro zamitundu, ndi kuzima kwa mdima.

3. Kuwala kwa Zomangamanga: Kuonjezera mphamvu pa nyumba zapakhomo, milatho, kapena malo owonetsera zaluso za anthu onse.

4. Mawonetsero a Zamalonda: Gwiritsani ntchito ma gradients amitundu yosiyanasiyana ndi zizindikiro zamadontho kuti muwonetse bokosi lanu.

7. Kuthetsa Mavuto Ofala a DMX

1. Zipangizo zoyatsira: Nthawi zambiri zimachitika chifukwa cha chingwe cholakwika kapena zoletsa zomaliza zomwe sizikupezeka.

2. Zipangizo zosagwira ntchito: Yang'anani ngati zakonza zolakwika kapena sinthani chingwe cholakwika.

3. Kulamulira kwapakati: Chenjerani ndi kusokonezeka kwa maginito amagetsi—sinthani mawaya a zingwe kapena onjezerani mikanda ya ferrite.

4. Kugawa zinthu mopitirira muyeso: Ngati zipangizo zoposa 32 zimagawana malo amodzi, gwiritsani ntchito chogawa chomwe chikugwira ntchito.

8. Njira Zapamwamba ndi Mapulogalamu Opanga

1. Kujambula zithunzi za pixel: Gwiritsani ntchito LED iliyonse ngati njira yosiyana kuti mujambule makanema kapena zojambula pakhoma.

2. Kugwirizanitsa nthawi: Lumikizani ma DMX cues ku audio kapena kanema (MIDI/SMPTE) kuti muwone bwino nthawi.

3. Kulamulira kogwirizana: Phatikizani masensa oyenda kapena zoyambitsa zomwe omvera amayambitsa kuti kuwala kukhale kogwirizana kwambiri.

4. Zatsopano zopanda zingwe: Pa malo omwe mawaya sagwira ntchito, gwiritsani ntchito Wi-Fi kapena makina apadera a RF-DMX.
