Yintoni iCable ye-DMX? IsiKhokelo sakho esiGqibeleleyo kwiiCables zokuKhanya kwiSigaba soBuchule

Ukumisela izibane zeqonga, izixhobo zesandi, okanye izixhobo ezikhethekileyo? Ukuqonda yintoni intambo ye-DMX yiiba linyathelo lakho lokuqala ukuya ekusebenzeni okuthembekileyo. Iintambo ze-DMX zisebenza njengomqolo wedijithali weenkqubo zokulawula izibane zanamhlanje, zithumela imiyalelo echanekileyo ukusuka kwiikhonsoli zokukhanyisa ukuya kwizinto ezizimeleyo ezinokuthembeka kwelitye kunye nesantya sombane.

Intambo ye-DMX yintambo ekhethekileyo ekhuselweyo ejijekileyo eyakhelweyo ngokukodwa ukuthumela imiqondiso yeprotocol ye-DMX512 phakathi kokulawula ukukhanya kunye nokulungiswa. Ngokungafaniyo neentambo zomsindo eziqhelekileyo, iintambo ze-DMX zibonakalisa umqobo obambekayo we-120 ohms kunye nokhuso oluqinileyo oluphindwe kabini ukugcina ingqibelelo yomqondiso kuyo yonke imigama emide kwindawo enengxolo ye-electromagnetic.

Ukuqonda iProtocol yeDMX512 kunye neDigital Lighting Control Systems

Yintoni eyenza i-DMX512 ibe ngumgangatho woShishino?

I-protocol ye-DMX512 (i-Digital Multiplex ene-512 values), esekwe yi-United States Institute for Theatre Technology (USITT) kwi-1986 kwaye kamva ilungelelaniswe njenge-ANSI E1.11-2008, yatshintsha ulawulo lokukhanyisa ubuchwephesha ngonaphakade. Le protocol ivumela i-console yolawulo enye ukuba ilawule ukuya kuthi ga kwi-512 itshaneli nganye ngaphakathi "kwindalo yonke," kunye netshaneli nganye ephethe amaxabiso olawulo lwe-8-bit (0-255) ukwenzela ukufiphala okuchanekileyo kunye nokulawula umbala.

Isebenza kwi-RS-485 yokwahluka komqondiso kwi-250 kbps, i-DMX512 ihambisa uhlaziyo lwexesha lokwenyani kumaxabiso ukuya kuthi ga kwi-44 yezakhelo ngomzuzwana. Oku kuthetha utshintsho olugudileyo kunye neziphumo ngalo lonke ixesha. Ukuthembeka kweprothokholi kuvela kukuhanjiswa komqondiso okwahlukileyo, okwala ngokwendalo ukuphazamiseka kwe-electromagnetic okuqhelekileyo kwindawo yeqonga egcwele izibane zokukhanya ezinamandla kunye nezixhobo zeaudio.

I-DMX yohluke njani kwiiProtocol ze-Art-Net kunye ne-sACN

Ngelixa i-DMX512 ihleli iyisiseko somthetho, ufakelo lwangoku lusebenzisa iindlela ezizezinye ezisekelwe kwi-Ethernet ezifana ne-Art-Net kunye ne-sACN (Ukusasaza i-ACN). Ezi prothokholi zintsha zinokusasaza iiyunivesiti ezininzi ze-DMX ngaphezulu kweziseko zonxibelelwano ezisemgangathweni, ezixhasa amawaka eziteshi ngaxeshanye. Nangona kunjalo, uqhagamshelo lwentambo ye-DMX ebonakalayo luhlala lubalulekile ekudibaniseni ukulungiswa komntu kwiinodi zenethiwekhi kunye nokugcina ukuhambelana nezixhobo ezindala.

Ulwakhiwo lweCable ye-DMX: Kutheni i-120 Ohm Impedance ibalulekile kwiMfezeko yoMqondiso

Indima enguNdoqo yoMbane woMfanekiso

I-120-ohm yeempawu zokuphazamiseka kweentambo ze-DMX azizenzeki-zihambelana ngokuthe ngqo ne-RS-485 yabamkeli abahlukeneyo kunye nabathumeli. Olu ngqamaniso lokumelana lunqanda ukubonakaliswa komqondiso okunokubangela urhwaphilizo lwedatha, ukwehla kwesakhelo, okanye izibane ezidanyazayo. Xa iintambo ezingezizo (ezinje ngeentambo zeaudio ezingama-75-ohm) zitshintshwa, ukungahambelani kwe-impedance kudala amaza amileyo awonakalise umgangatho wesignali, ngakumbi ukubaleka ixesha elide.

Izinto zoKwakha iCable yeDMX yobuNgcali

I-120-ohm yeempawu zokungaphumeleli kwe Iintambo ze-DMX Ayisiyonto ingaqhelekanga-ihambelana ngokukodwa ne-RS-485 eyahlula abamkeli kunye nabathumeli. Olu ngqamaniso lokumelana lunqanda ukubonakaliswa komqondiso okunokubangela urhwaphilizo lwedatha, ukwehla kwesakhelo, okanye izibane ezidanyazayo. Xa iintambo ezingezizo (ezinje ngeentambo zeaudio ezingama-75-ohm) zitshintshwa, ukungahambelani kwe-impedance kudala amaza amileyo awonakalise umgangatho wesignali, ngakumbi ukubaleka ixesha elide.
