Botae, paw ne multiswitch a wɔde di dwuma ma satellite dish

Satellite television
bere no reyera nkakrankakra, na ɛrebue hokwan foforo ama Intanɛt so television. Nanso, ɛnyɛ okyinnsoromma yi so beae biara na Intanɛt wɔ hɔ mprempren. Sɛnea ɛbɛyɛ na wɔanya ofie kɛse bi a satellite ne asase so sɛnkyerɛnne wom no, wɔde multiswitch di dwuma. Momma yɛnhwehwɛ ne mfiri no mu nkɔ akyiri, nea enti a ehia ne sɛnea ɛka bom.

Dɛn ne nea enti a wuhia multiswitch ma satellite dishes

Multiswitch no di dwuma sɛ “equalizer” ne “distributor” bi ma satellite ne asase so sɛnkyerɛnne no. Nokwarem no, eyi yɛ mfiri ketewaa bi a ɛma wɔn a wɔpɛ TV no asetra yɛ mmerɛw kɛse.

Dɛn nti na wuhia

Sɛ wobɛte nea enti a wuhia multiswitch ase a, ɛsɛ sɛ wudi abɛbusɛm biako ho dwuma: sɛnea wubetumi de television a ɛte sɛ satellite ama wɔn a wɔakyerɛw wɔn din no a wuntwaa mu. Bere a na satellite television agye din kɛse no , asɛmmisa a anibere wom yi sɔree maa wɔn a wɔyɛ adwuma no . Ɔkwan a edi kan na ɛyɛ mmerɛw sen biara no da adi pefee: client biako = antenna biako/satellite a wɔde di dwuma. Nnuru a wɔde yɛ aduan no yɛ mmerɛw. Nanso, ne ɔkwan a ɛnyɛ den a wobetumi afa so no, ɔhaw ketewaa bi sɔre: sɛ adan 48 na ɛwɔ ofie no mu, na ɔdan biara pɛ sɛ wɔde satellite TV si hɔ a, ɛnde antena 48 bɛba ofie no atifi a ɛde data mena. Eyi kyerɛ sɛ, nneɛma a wɔde mena no bɛkata ɔdan no atifi koraa. Wɔ mmeae bi no, ɛnyɛ mmerɛw, na ebinom nso wɔabara koraa.

Ɔkwan a ɛto so abien ne sɛ wode satellite converter bɛhyɛ mua outputs dodow ne subscribers dodow yɛ pɛ. Nanso, ha no, ɛnyɛ wɔn a wɔakyerɛw wɔn din wɔ fie hɔ nyinaa nko na ɛsɛ sɛ obi susuw ho, na mmom wɔn a wobetumi akyerɛw wɔn din nso. Afei nso wɔ gua so seesei ɛyɛ den sɛ wobɛnya converter a ɛwɔ bɛboro 4 outputs. .

Sɛnea wobɛpaw mfiri ahorow a ɛwɔ hɔ

Sɛ worepaw a, ɛsɛ sɛ wufi ase fi nneɛma abien so: nsɛntitiriw dodow a wode bɛka ho ne baabi a ɛne antena no ntam kwan ware. Sɛnea su titiriw no kyerɛ no, wɔakyekyɛ multiswitch no mu ayɛ no:

1. Tumi a wɔde ma: efi 220 V na efi 18 V.
2. Dodow a ɛwɔ hɔ a ɛwɔ input ne output ports.

Nsɛntitiriw dodow no bɛma woate output dodow a wuhia na ama woagye sɛnkyerɛnne no koraa ase.

Cascadable anaasɛ terminal

Ɔkwan a ɛda antenna no ntam no nya multiswitch a wɔhwehwɛ no so nkɛntɛnso tẽẽ: cascaded anaa terminal.

Wɔde Cascaded di dwuma kɛse wɔ adan a ɛwɔ adan akɛse mu, nnwumakuw adwumayɛbea ne adan a nnipa dodow bi te mu. Saa mfiri yi nhia ahoɔden na wɔde nkɔnsɔnkɔnsɔn bi ka ho wɔ baabi a wɔkyekyɛ nsɛnkyerɛnne (mpɛn pii no abansoro biara wɔ ɔdan bi mu). Ɛho hia sɛ wɔde mfiri ahorow no bata wɔn ho wɔn ho ho. Sɛ ɛho hia sɛ wɔde signal amplifier bata ho a, wɔde power injector abɔ mu, a ɛhwehwɛ sɛ AC outlet a ahoɔden yɛ 220 volts.

Afiri no ka switchboard no ho, efisɛ ɛno mu na nhama a efi antenna no mu no hyɛn mu na nhama no fi mu kɔ receiver no mu. Terminal multiswitch no hia anyinam ahoɔden. Ɛne sɛ, wɔ mita bi radius mu no, ɛsɛ sɛ socket bi a AC supply a ɛyɛ 220 volts wɔ hɔ.

Multiswitches a ɛyɛ adwuma ne nea ɛnyɛ adwuma

Afei nso, akuw ahorow te sɛ active ne passive multiswitch models wɔ hɔ. Active model no bi ne signal amplifier a wɔaka abom. Saa ade yi ho hia sɛ wopɛ sɛ wode antenna a ɛwɔ mframa mu nso bata ho a. Nea ɛbɛyɛ na nea wɔpaw no ayɛ mmerɛw no, nnwumakuw binom kyerɛw wɔn nneɛma din sɛnea edidi so yi:

Wɔ passive category no fam no, wɔmfa saa hokwan yi mma. Sɛ wɔbɛyɛ eyi a, wɔde abɔnten so type amplifier foforo bi abɔ mu, na ɛsɛ sɛ wɔtɔ no soronko. Passive ne active multiswitches yɛ soronko wɔ wɔn ho wɔn ho ho wɔ parameters a ɛwɔ input signal no mu: passive de no bɛma indicator a ɛba fam.
