Chinangwa, kusarudzwa uye kushandiswa kwemultiswitch kune satellite dish

Nguva yeterevhizheni yesatellite iri kupera zvishoma nezvishoma, ichivhura mikana mitsva yeterevhizheni yeInternet. Nekudaro, hazvisi zvese zvepasi pano zvine Internet ikozvino munharaunda yeruzhinji. Kupa imba huru ine satellite uye chiratidzo chepasi, multiswitch inoshandiswa. Ngationgororei zvakadzama mudziyo wayo, nei ichidikanwa uye kuti yakabatana sei.

Chii uye nei uchida multiswitch kune satellite ndiro

Iyo multiswitch inobata basa remhando ye “equalizer” uye “mugovera” kune satellite uye chiratidzo chepasi. Muchokwadi, ichi chishandiso chidiki chinorerutsa zvakanyanya hupenyu hwevanoda TV.

Sei uchida

Kuti unzwisise kuti nei uchida multiswitch, unofanirwa kugadzirisa chirahwe chimwe chete: iwe unogona sei kupa vanyoreri vako satellite-mhando terevhizheni. Panguva yekurumbira kukuru kwesetiraiti terevhizheni , uyu mubvunzo wakakomba wakamuka kune vanoshanda . Yekutanga uye yakapusa sarudzo iri pachena: mutengi mumwe = antenna imwe/satellite. Nzira yacho iri nyore. Zvisinei, pamwe chete nechisarudzo chiri nyore, dambudziko riri nyore rinomuka: kana pane dzimba makumi mana nemasere mumba, uye imba imwe neimwe inoda kuisa satellite TV, ipapo pachava ne48 antenna padenga reimba iyo inotumira data. Izvi zvinoreva kuti denga richafukidzwa zvachose nevanotumira. Mune dzimwe nzvimbo hazvina kunaka, uye mune dzimwe zvinorambidzwa zvachose. Chinonyanya kukanganisa iboka retambo dzinoratidzwa kune imwe nzvimbo yekunze uye dzinogona kungobiwa kubva padenga. Chechipiri sarudzo ndeyekuisa satellite converternehuwandu hwezvabuda zvakaenzana nenhamba yevanyoresa. Zvisinei, pano munhu anofanira kufunga kwete chete vanyori vose mumba, asiwo vanogona kunyoresa. Zvakare pamusika zvino zvakaoma kuwana shanduko ine zvinopfuura 4 zvabuda.

Inosunungura matenga nemafacade ezvivakwa zvekugara , kuve nechokwadi chekugamuchira chiratidzo kune vese vagari.

Nzira yekusarudza kuti ndeapi marudzi emudziyo aripo

Paunosarudza, iwe unofanirwa kutanga kubva pazvinhu zviviri: nhamba yemapoinzi ekubatanidza uye kuti ari kure sei kubva kune antenna. Zvinoenderana nehukuru hunhu, iyo multiswitch yakakamurwa kuita:

1. Simba rekushandisa: kubva ku220 V uye kubva ku18 V.
2. Inowanikwa nhamba yekupinza uye kubuda madoko.

Nhamba yemapoinzi inokubvumira kuti unzwisise kuti zvingani zvinobuda zvaunoda kuti unyatsotora chiratidzo.

Cascadable kana terminal

Kureba kune antenna kunobata zvakananga mhando inodiwa yemultiswitch: cascaded kana terminal.

Cascaded inoshandiswa zvakanyanya muzvivako zvemafurati, mahofisi emakambani uye zvivakwa zvekugara zvine nhamba huru yevanhu. Iri rudzi rwechigadzirwa hachidi simba uye rinowedzerwa neketani panzvimbo yekugovera chiratidzo (kazhinji pasi pese muchivakwa). Izvo zvakakosha kuti zvishandiso zvakabatana kune mumwe nemumwe. Kana zvakakosha kubatanidza chiratidzo che amplifier, injector yemagetsi yakabatana, inoda AC outlet ine simba re 220 volts. Terminalmultiswitch mhando inokurudzirwa kuti iiswe mudzimba dzega kana mumakamuri madiki. Izvi zvinokonzerwa nechinhambwe chepedyo kune antenna. Chigadzirwa chacho chinosanganiswa mubhodhi rekushandura, nokuti iri mairi umo tambo dzinobva kune antenna dzinopinda uye kubva kune iyo tambo dzinoenda kune anogamuchira. Iyo terminal multiswitch inoda magetsi. Kureva, mukati me radius yemamita panofanira kunge paine socket ine AC inopihwa ye220 volts.

Active uye passive multiswitches

Kune zvakare mapoka akadai seanoshanda uye passive multiswitch modhi. Iyo inoshanda modhi inosanganisira yakabatanidzwa chiratidzo amplifier. Ichi chimiro chinodiwa kana iwe uchidawo kubatanidza on-air antenna. Kurerutsa sarudzo, mamwe mabhureki anoisa zvigadzirwa zvawo sezvizvi:

1. P – passive.
2. A – inoshanda.
3. U – universal type.

Pachikamu chepasi, mukana uyu hauna kupihwa. Kuti uite izvi, imwe yekuwedzera yekunze mhando amplifier yakabatana, iyo inofanirwa kutengwa zvakasiyana. Passive uye inoshanda multiswitches inosiyana kubva kune imwe neimwe mumatanho eiyo yekuisa chiratidzo: iyo passive ichapa yakaderera chiratidzo.

Chii chinonzi multiswitch, chinangwa uye kushandiswa kwechigadzirwa:

Kubatanidza uye kugadzirisa

Iyo multiswitch ine zvibatanidza zvekupinza (inodiwa kune vanoshandura ), uye inobuda (yevanogamuchira). Nhamba yezvibatanidza zvinobuda zvakaenzana nenhamba yevanogamuchira vakabatanidzwa. Nhamba yevanogamuchira inoenderana nenhamba yevatengi vakabatana. Kunzwisisa kukosha kwebasa rezvibatanidza zvinobuda kune zvishoma zvakaoma. Chiratidzo cheKu-bhendi chinodyiswa mukati mayo, iyo yakakamurwa kuva marudzi epolarization pamwe chete nemabhendi maviri. Izvi zvinoreva kuti kuti ugamuchire yakazara yakazara yerukova kubva kune imwe yekufambisa mudziyo (munyaya yedu, setiraiti), iwe uchafanirwa kushandisa 4 switch inopinza, ichibatanidza kune ina inoshandura inobuda (mune dzimwe nguva, akasiyana anoshandura). Antenna yepasirese yenguva dzose inofanirwa kubatana kune chinongedzo chine “Terr” chinyorwa, kana chiratidzo kubva kune vhidhiyo kamera kunze. Kubatanidza radial multiswitch, chirongwa chinotevera chinoshandiswa:
Nhamba inoratidza iyo MR516 modhi. Zvichienderana nezita mune fomula, chirongwa chichava 5 * 16. Pachave ne5 yekupinda (1 yeterrestrial TV), uye 4 yekufambisa setiraiti. 4 yekubatanidza nekuti imwe neimwe polarization ine mativi maviri.

Zano! Inokurudzirwa kushandisa frequency 11700 MHz semuganho weiyo determinant yepasi nepamusoro renji. Icho chiratidzo ichi chiri rudzi rwekuparadzanisa.

Mushure meiyo-on-air antenna, TV renji amplifier inoiswa. Kazhinji, tsigiro yeTV mumultiswitches haina kufambisa, pasina kukwidziridzwa. Izvi zvinokonzerwa nekusiyana kwekugamuchirwa kwechiratidzo chepamusoro-soro, kushandiswa zvisina kunaka kuchaita kuti kuvhiringidzika. Mufananidzo uri pazasi unoratidza girafu rekubatanidza mudziyo kune maviri anoshandura kubva kune akasiyana antenna uye kune imwe yepasirese:
Nhamba iri pamusoro inoratidza kuti quad converter inobuda sei mundiro yega yega. Pakupedzisira, zvakazobuda zvisere zve satellite, 32 zvakabuda uye yakajairwa 1 yechiratidzo chepasi neamplification paTV. Iyo cascade multiswitch yakabatana sezvinotevera:
Model MV516 inoratidzira inofa-cast simbi imba inodzivirira chimiro kubva kunze kwemagetsi kukanganiswa. Kune ese ari maviri anongoita uye anoshanda nzira dzepanyika TV. Maitiro ekubatanidza gumi maTV kune imwe antenna uchishandisa multiswitch: https://youtu.be/BjFxA5Fv_IM

Inowanzo bvunzwa Mibvunzo uye Mhinduro

Mubvunzo wekutanga unowanzo bvunzwa ndewekuti: “Ndeipi mhando yechiratidzo inogona kuendesa multiswitch?”. Mhinduro: mukuwedzera kune yakajeka satellite kutendeuka, iyo multiswitch inodyisawo pa-air amplifiers kuburikidza nekupinza kweTV. Mubvunzo wechipiri ndewokuti: “Sei ndisingagoni kungoshandisa mugamuchiri?”. Mhinduro: unogona, asi iyi sarudzo haina kukodzera kumakamuri umo isingabvumirwe kuisa isingapfuuri 3 vanogamuchira. Usakanganwa kuti chiratidzo chinopatsanurwa, nokudaro kugadzira mhedzisiro yemaoko akasungwa. Mubvunzo wechitatu ndewokuti: “Ndingaderedza sei mutoro unouya pamugamuchiri ini?”. Mhinduro: Kuti uite izvi, zvinokurudzirwa kutenga multiswitch, iyo yakaparadzana magetsi yakatoiswa. Mubvunzo wechina: “Ndingashandisa multiswitch, DiSEqC uye diplexer kune imwe satellite system?”.Mhinduro: “Tekinoroji dzemazuva ano dzinoita kuti zvikwanise kuita izvi pasina matambudziko.” Mubvunzo wechishanu: “Ndeipi shanduko yandinofanira kutora yeEuropean satellite?”. Mhinduro: “Universal”. Mubvunzo wechitanhatu: “Ndinoda kubatanidza vanogamuchira 2 kune imwe ndiro. Ndeipi yakanakisa kugamuchira kutenga? Mhinduro: kwete, unoda converter. Mubvunzo wechinomwe: “Chii chinonzi switch?”. Mhinduro: DiSEqC. Nheyo huru yemudziyo uye pfungwa yekushanda kwemultiswitch iri nyore: mashoma antennas kuti ave nevashandisi vakawanda. Uye ndizvo zvazviri. Imwe diki gadziriso inogona kutsiva boka remarata esimbi, uye kuenzanisa kusawirirana kwenzvimbo dzinoverengeka dzekugara. Inoshandiswa kupatsanura chiratidzo.
