Yintoni i-DiSEqC, indlela yokuyikhetha kunye nendlela yokudibanisa i-dysic

Xa ubukele iTV yesathelayithi , umqondiso ufunyanwa kwenye yeesathelayithi. Iya kwisiguquli , ukusuka apho idluliselwe kumamkeli wesathelayithi. Ukuba, ngenxa yaso nasiphi na isizathu, umsebenzisi ufuna ukufumana uphawu oluphezulu oluvela kwiisathelayithi ezininzi, kufuneka asebenzise umguquli ohlukeneyo ngamnye kubo. Nangona kunjalo, inye kuphela kubo inokudityaniswa kumamkeli ngexesha elinye. I-DiSEqC sisitshixo esidityaniswe phakathi komguquli kunye nomamkeli. Idibanisa isiguquli kwisathelayithi efunekayo ukujonga iinkqubo zayo. Ukusebenza kolu tshintsho kusekelwe kwiprotocol enegama elifanayo. Yenzelwe ukuphumeza umgangatho ohambelanayo. Intambo ye-coaxial isetyenziselwa ukusebenza. Isignali ihanjiswa ngayo, i-voltage yokubonelela yokuguqula, kunye nesignali yethoni yokulawula. Iprothokholi ibonelela ngamanqanaba amaninzi osetyenziso, acwangciswe ngokoluhlu. Ukuba isixhobo sixhasa enye yazo, kuya kuqinisekisa kwakhona ukusetyenziswa kwazo zonke ezisezantsi. Kusetyenziswa iinguqulelo ezininzi zomgangatho, eyona ixhaphakileyo yiDiSEqC 1.0. Esi sixhobo sine-microcontroller kunye nesoftware ekhethekileyo ngaphakathi. Ukutshintsha okunjalo kukuvumela ukuba ufumane imiqondiso kwiisathelayithi ezininzi usebenzisa i- eriyali enye.. Oku kwandisa inkululeko yokuzikhethela xa ubukele iinkqubo.

Isebenza njani idiski

Isixhobo siqhagamshelwe kwisamkeli sesathelayithi kunye neziguquli ezininzi. Ngokuqhelekileyo ababini okanye abane abafumana umqondiso wesathelayithi baqhagamshelwe kwiDiSEqC. Emva kokudibanisa, umamkeli uqwalaselwe. Xa usebenzisa izikimu zoqhagamshelwano ezintsonkothileyo, unokwandisa kakhulu inani labaguquli abadityanisiweyo.

Umfanekiso ubonisa enye yeenketho zoqhagamshelwano olunjalo. Abaguquli baqhagamshelwe ngokuthe ngqo kwiiDiSEqC ezimbini 1.0. Ezi zixhobo ziqhagamshela kwi-DiSEqC 1.1. Ngaloo ndlela, umamkeli unokudibaniswa nabaguquli abasibhozo. Xa udibanisa umguquli, qinisekisa ukuba ubude bekhebula abukho ngaphezu kweemitha ezi-3. Ngaphandle koko, umgangatho womqondiso ofunyenwe ngummkeli uya kuhla.

Ngexesha lenkqubo yokudibanisa, kufuneka ucime umbane kumamkeli ukuze ugweme umngcipheko womonakalo kuwo.

Zeziphi iintlobo zokutshintsha kweDiSEqC kwimarike

I-DiSEqC 1.0 lolona hlobo luqhelekileyo. Ezo zixhobo zinokudityaniswa ngaxeshanye nezamkeli ezine zesathelayithi. Ukusebenzisa i-DiSEqC 1.1 ikuvumela ukuba unyuse inani lezixhobo eziqhagamshelweyo ukuya kutsho kwi-16. Esi sixhobo sinokuqhagamshela ngokuthe ngqo kubaguquli okanye usebenze nabo ezinye iiswitshi. Ikuvumela ukuba uqhagamshelane neDiSEqC 1.0 ezine, nganye kuzo isebenza nabaguquli be-4.
Ukumisela i-DiSEqC 1.1 – indlela yokudibanisa i-satellites ye-8: https://youtu.be/f9lzw5vT-I8 DiSEqC 1.2 yongezelela isebenza njenge-satellite dish rotator. Isetyenziselwa ukubeka ngokuchanekileyo i-eriyali kwisathelayithi esasazayo. Umtshintshi unokudibanisa ngokuthe ngqo abaguquli. Ezinye iimodeli zeDiSEqC 1.2 aziboneleli ngesakhono sokusebenza nabanye abaguquli.
Kukho i-DiSEqC 2.X, enika amandla okufumana isiqinisekiso xa uphumeza imiyalelo. Ngaloo ndlela, utshintsho lunokufumana ulwazi olongezelelweyo malunga nezixhobo ezinxulumene nayo.
Umgangatho we-DiSEqC 3.X unamandla okunxibelelana kunye nezixhobo ze-peripheral. Eli thuba alikasetyenziswa ngokupheleleyo. Kwixesha elizayo, kucwangciswe ukuqinisekisa uqwalaselo oluzenzekelayo ngolu hlobo.

Uqhagamshela njani ngokufanelekileyo iDiSEqC kwaye usete isixhobo

Emva koko, siza kuthetha ngokudibanisa i-DiSEqC 1.0 kwi-Amos, i-Hotbird kunye ne-Astra satellites. Emva kokufaka i-eriyali, kufuneka uqinisekise ukuba abaguquli bafumana iimpawu. ukusuka kwiisathelayithi ezihambelanayo. Emva koko kufuneka udibanise umguquleli ngamnye kwisidibanisi seDiSEqC esihambelanayo. Xa umamkeli ecimile, qhagamshela kwisitshixo usebenzisa intambo. Ukwenza oku, sebenzisa isinxibelelanisi esifanelekileyo seDiSEqC. Emva koko umamkeli uvuliwe. Ngoku kufuneka uqwalasele. Ukwenza oku, umamkeli uqhagamshelwe kwisidibaniso esihambelanayo somamkeli kamabonakude. Emva kokuvula iTV, kufuneka uye kwisethingi yomamkeli. Isicwangciso separameter yeesathelayithi ezikhankanyiweyo siya kuboniswa. Xa useto luvula, kwimenyu evelayo, yiya kwicandelo “loMphathi wesitishi seTV”. Okulandelayo, kufuneka uye kwicandelwana elithi “Ufakelo”. Okulandelayo, kufuneka wenze la manyathelo alandelayo.
Kumgca weDiSEqC ubeke iqhezu 1/4. Kuyo, i-numerator yinombolo yesiqhagamshelo apho i-converter ehambelanayo idibaniswe, kwaye i-denominator ilingana nenani lezixhumanisi ezikhoyo. Kuboniswe apha iiparamitha zesathelayithi yeAstra. Okulandelayo, qwalasela iHotbird, intambo eqhagamshelwe kuyo kwizibuko lesibini.
Iparamitha yeDiSEqC iya kuba yi-2/4. Isathelayithi ka-Amos yayiqhagamshelwe kwizibuko lesi-3.
Apha iparameter ehambelanayo ngu 3/4. Emva kokuba useto lugqityiwe, umsebenzisi uya kuba nakho ukuqala ukubukela iinkqubo zeTV. Inkqubo yokumisela abamkeli abahlukeneyo iyafana, kodwa iinkcukacha zinokwahluka. Umzantsi weskrini sesethingi ubonisa iimpawu zesignali efunyenweyo. Inqanaba kunye nomgangatho ziboniswa njengepesenti. Emva kokuba igalelo ligqityiwe, kufuneka ugcine useto olwenziweyo. Ukwenza oku, cofa nje iqhosha elithi “Menu”. Ukuba i-diagram ye-wiring yokutshintsha eyinkimbinkimbi isetyenzisiweyo, ngoko i-denominator yeqhezu iya kubonisa inani elipheleleyo labadibanisi abakhoyo. Ukuba ngokuhamba kwexesha umnini uthenga ummkeli omtsha okanye uhlaziya i-firmware yayo, ke ukuseta kuya kufuneka kwenziwe kwakhona.

Indlela yokukhetha i-daisik

Ngaphambi kokuba uthenge i-DiSEqC, kufuneka uthathe isigqibo sokuba uceba ukuyisebenzisela ntoni. Ngokuxhomekeke ekubeni bangaphi abaguquli abamele badityaniswe, khetha uhlobo lwesixhobo kunye neskimu soqhagamshelwano. Xa uthenga, kufuneka ukhethe umenzi othembekileyo. Ngokomzekelo, kule nto unokugxila kwiimpawu ezidumileyo. Iimodeli zokuqala zinokuqhagamshelwa kuphela kwiziguquli ezimbini. Ngoku eli nani leeqhagamshelo lithathwa njengelinganelanga. Eyona isetyenziswa ngokuqhelekileyo iDiSEqC 1.0, eyenzelwe ukusebenza ngezixhobo ezine. Kukho iinketho ezineevenkile ezintandathu okanye ezisibhozo. Ekubeni umehluko wexabiso phakathi kwabo ungabalulekanga, kungcono ukuthenga okokugqibela.

Iingxaki zonxibelelwano ezinokwenzeka

Ukusetyenziswa kweDiSEqC kukuvumela ukuba ngaxeshanye ube nokufikelela kwiisathelayithi ezininzi. Nangona kunjalo, ngamanye amaxesha emva kokudibanisa ngolu tshintsho, umqondiso uyanyamalala ngokupheleleyo okanye ngokuyinxenye. Oku kunokubangelwa yile miba ilandelayo:

1. Esona sizathu sinokuba ngumgangatho ophantsi wokwamkela . Ngoko ke, kubalulekile ukujonga ukuchaneka kokulungelelaniswa kwe-antenna. Kufuneka uqiniseke ukuba ibekwe ngokuchanekileyo kwaye akukho miqobo kwindlela yomqondiso.
2. Kwezinye iimeko, unobangela usenokuba intambo ayifakwanga kakuhle . Ukujonga oku, kuya kufuneka ujonge umdibaniso ngamnye.
3. Ngamanye amaxesha iingxaki zokufumana zingenzeka ngenxa yokuba umsebenzisi ukhohliwe ukuhlawula amajelo ahlawulelwayo . Kule meko, kufuneka uhlolisise ibhalansi kwaye ufake imali efunekayo yokuhlawula.
4. Ukuba i-antenna isetyenziswe ixesha elide, kwaye i-DiSEqC ifakwe ngaphandle, ngoko ke ithuba lokuba lingonakaliswe yimozulu embi ayinakukhutshwa .

I-DiSEqC sisixhobo sombane esintsonkothileyo. Ukuze kuqinisekiswe ukusebenza kakuhle kwediski, kuyimfuneko ukulandela imigaqo yokusebenza kwayo. Ujonga njani ukusebenza kwe-dysik: https://youtu.be/iXkmymR0K98

Imibuzo neempendulo

Umbuzo: “Ukuba umsebenzisi uthenge isitya sesathelayithi kwaye ufuna ukufumana imiqondiso kwiisathelayithi ezimbini, akanakukwazi ukuthenga eyesibini kule nto?” Impendulo: “Ngoncedo lwe- multifeed , unokuvula i-eriyali kwiisathelayithi ezimbini okanye ngaphezulu. Inani leziguquli ezisetyenzisiweyo kufuneka lingqinelane nenani lesathelayithi zosasazo. Ngamnye wabo uqhagamshelwe kwisixhobo seDiSEqC, kwaye ngayo ukuya kumamkeli wesathelayithi. Emva koko ukwamkelwa kweetshaneli kufuneka kulungiswe. Umbuzo: “Ndingenza ntoni ukuba iisathelayithi ezininzi ziqhagamshelwe, kodwa uphawu olufunyenwe kuzo alukho kumgangatho owaneleyo?”Impendulo: “Kule meko, kufuneka wenze enye yezinto ezimbini: lungisa kakuhle nganye kuzo okanye wandise ubungakanani be-eriyali. Kwezinye iimeko, kufuneka ususe umqobo kwindlela yomqondiso. Ngokomzekelo, ukuba umthi uyawufihla, ke isitya sesatellite kufuneka sibekwe kwindawo eyahlukileyo.
