23/01/27I-Dhyana 401D kunye ne-FL20-BW zisebenzisa uhlobo lokuvuselela ngokusebenzisa i-optocoupler isolated circuit - umgangatho woshishino osetyenziswa ngokubanzi osetyenziselwa ukwahlula i-electronics yekhamera echanekileyo kuyo nayiphi na i-electromagnetic yangaphandle okanye ukuphazamiseka. Iimfuno ze-optocoupler zodwa ezibangela iisekethe zihluke kancinane kwezo zomgangatho we-TTL osetyenziswa kwezinye iikhamera.
I-optocoupler ngokwayo iyinxalenye yombuso oqinileyo oquka i-diode ephumayo yokukhanya (i-LED), kunye ne-photosensitive transistor, esebenza njengokutshintsha. Xa ikhamera ifuna ukukhupha isiginali yetrigger, isixa esincinci sokukhanya sithunyelwa sisuka kwi-LED siye kwi-transistor ebuthathaka ukukhanya, ethi emva koko ivumele umsinga ukuba uqukuqele kuyo. Kodwa iisekethe ezimbini zihlala zodwa ngokupheleleyo komnye nomnye, okuthetha ukuba ikhamera ikhuselwe kulo naluphi na uphazamiseko lombane kwisixhobo sangaphandle. Ngokukwanjalo, izinto ezibangela igalelo zivuse ii-optocouplers ukuba zigqithise imiqondiso yazo kwikhamera.
Umzekeloukuqala ukuseta kwi-optocoupler-isolated triggering circuits. Ibhokisi eluhlaza okwesibhakabhaka edayiweyo ibonisa izixhobo zangaphandle kwikhamera. Umgca ophawulwe 'TRIGGER OUT' yi-Trigger Out pin yekhamera. Lonke ujikelezo uphindwa kwakhona kwimeko yezikhonkwane ezininzi ze-Trigger Out. Umthombo wombane we-VCC2 kunye ne-resistor R3 kufuneka zongezwe ngumsebenzisi.
Ngokungafaniyo ne-TTL ebangela ukuba i-camera ikhuphe uxhulumaniso lukwazi ukulawula ngokuthe ngqo umbane othunyelwe kunye nentambo yokuqalisa, umzekelo ukuthumela umqondiso we-5V ophezulu kwisixhobo sangaphandle, iisekethe ezizimeleyo ze-optocoupler zisebenza ngakumbi njengokutshintsha, ukulawula nje ukuba isiphaluka esipheleleyo senziwe okanye hayi. Amandla ombane kuloo sekethi kufuneka amiselwe (ekwabizwa ngokuba 'kukutsalwa') ngaphandle ngesixhasi. Okokugqibela ukwenza isekethe epheleleyo i-trigger circuit kufuneka iqhagamshelwe emhlabeni - ikhamera ine-'Trigger Ground' yephini eboniswe kwicandelo le-Pin-Out Diagrams elingezantsi ekufuneka liqhagamshelwe kumhlaba wombane.
Njengoko kubonisiwe kulo mzobo ungentla, umthombo wombane weVCC2 kunye ne-resistor R3 kufuneka zongezwe. I-voltage ekhuthazwayo yi-5V - 24V, kuxhomekeke kumbane olindelwe yi-trigger edibeneyo kwisixhobo sakho sangaphandle, nangona uninzi lwezixhobo ezinokuthi zibe yi-5V. I-resistor R3 inquma i-current equkuqelayo kwisiphaluka, kwaye ukuxhathisa okucetyiswayo yi-1KΩ.
