1. Intshayelelo kwi-DMX

I-DMX (i-Digital Multiplexing) yintsika yolawulo lwezibane zeqonga nezakhiwo zanamhlanje. Ivela kwiimfuno zeethiyetha, ivumela isilawuli esinye ukuthumela imiyalelo echanekileyo kumakhulu ezibane, oomatshini benkungu, ii-LED, kunye neentloko ezihambayo ngaxeshanye. Ngokungafaniyo ne-analog dimmers ezilula, i-DMX inxibelelana "ngeepakethi" zedijithali, ivumela abayili ukuba bakhethe ngokuchanekileyo utshintsho oluntsonkothileyo lombala, iipateni ze-strobe, kunye neziphumo ezihambelanayo.

2. Imbali emfutshane ye-DMX

I-DMX yavela phakathi kwiminyaka yoo-1980 njengoko ishishini lalifuna ukutshintsha iiprotokholi ze-analog ezingahambelaniyo. Umgangatho we-DMX512 ka-1986 wachaza ukuhanjiswa kweetshaneli zedatha ezifikelela kuma-512 ngentambo ekhuselweyo, nto leyo eyenza unxibelelwano phakathi kweempawu kunye nezixhobo lube semgangathweni. Nangona kukho iiprotokholi ezintsha, i-DMX512 iseyeyona isetyenziswa kakhulu kwaye ixatyiswa kakhulu ngokulula kwayo, ukuthembeka kwayo, kunye nokusebenza kwayo ngexesha langempela.
