Ngophuhliso olukhawulezayo lweshishini lokubonisa i-LED, imfuno yemakethe yekhadi lokulawula umboniso we-LED nayo iyanda, kwaye ikhadi lokulawula elingenazingcingo le-LED lingahlangabezana kakuhle neemfuno zabathengi kulawulo olumanyeneyo kunye nemarike yokuhanjiswa kweqela. Umzekelo, ipowusta led screen, iteksi top umboniso LED, ukukhanya pole LED ukubonisa kunye nomdlali led. Ulawulo olulula kunye nokugcinwa lula okukhokelela kwikhadi lokulawula umboniso lukhetho olulungileyo kubasebenzisi. Ukuze ugweme ilahleko engeyomfuneko, abasebenzisi kufuneka banikele ingqalelo kula manqaku alandelayo xa usebenzisa ikhadi lokulawula.
Okokuqala, faka ikhadi lokulawula kwindawo eyomileyo kwaye ezinzileyo. Ubushushu obugqithisileyo kunye nokufuma kunye nokusingqongileyo okunothuli kuyingozi kakhulu kwikhadi lokulawula.
Okwesibini, kunqatshelwe ngokungqongqo ukuplaga kunye nokukhupha i-port ye-serial ngaphandle kokungaphumeleli kwamandla ukukhusela ukusebenza okungafanelekanga ekonakalisa i-serial port yekhompyutheni kunye ne-serial port yekhadi lokulawula.
Okwesithathu, akuvumelekanga ngokungqongqo ukulungelelanisa igalelo lombane wekhadi lokulawula xa inkqubo isebenza, ukwenzela ukuba ugweme umonakalo kwi-port ye-serial port kunye nekhadi lokulawula i-serial port ngenxa yokulungelelaniswa okungafanelekanga kunye nombane ogqithiseleyo. Umbane oqhelekileyo osebenzayo wekhadi lokulawula ngu-5V. Xa ulungelelanisa i-voltage yombane, ikhadi lokulawula kufuneka lisuswe kwaye lilungiswe ngokukhawuleza ngemitha yendalo yonke.
Ngaphambili, kunqatshelwe ngokungqongqo kwi-short-circuit ye-terminal yomhlaba yekhadi lokulawula kunye nesakhelo sokubonisa okukhokelwayo, ngaphandle koko, ukuba umbane we-static uqokelela, kulula ukuyonakalisa i-serial port yekhompyutheni kunye ne-serial port yekhadi lokulawula, okubangelwa kunxibelelwano olungazinzanga. Ukuba umbane ongatshintshiyo unzima, ikhadi lokulawula kunye neskrini esikhokeleyo siya kutshiswa. Ke ngoko, xa umgama wolawulo lwesikrini okhokelwayo ukude, sicebisa abasebenzisi ukuba basebenzise i-serial port isolator ukunqanda umonakalo kwi-port ye-serial port kunye nomtya wekhadi lokulawula ngenxa yeemeko ezirhabaxa ezinje nge-loops yomhlaba, i-surges, ukubetha kombane kunye ne-hot plugging line port. .
Okwesihlanu, kuyimfuneko ukuqinisekisa uxhulumaniso oluchanekileyo phakathi kwekhadi lokulawula kunye ne-port ye-serial port ukuphepha umonakalo kwi-port ye-serial yekhadi lokulawula kunye ne-port ye-serial port yekhompyutha ngenxa yeempawu zokungenisa ezingalunganga.
Ikhadi lokulawula umboniso we-LED yeyona eq engundoqo
