Conectando dos o más gtmedia

Post by Gguzman »

Hola amigos
Tengo 3 decodificadores Gtmedia V8x que quiero conectar al único cable que viene de la antena. Consulta: se pueden conectar en serie dentro de la casa? Hay problema eléctrico? .
Agradezco anticipadamente sus respuestas.

Ninguno siempre que uséis la misma polaridad y tono

If you use a satellite frequency band splitter, there are diodes in the splitter that stop the power from passing back to the other units. You need "All Ports Power pass" as that allows the power from the box to the LNB.
The only issue you will then have is that any set top box that uses H polarity (18 volts) will stop any other box trying to use V polarity (13V). This is not a power short and damage thing, just that the LNB will "See" the higher voltage only.
When one user selects a channel on H the other user will see "No Signal" if watching a V channel.

There are two output LNB's that allow sharing and "One Cable Solution" C band LNB's that move the V polarity to a higher frequency so all the users can share for C Band LNB's

If most of the channels you and the other users watch are all on the same polarity, then you will have few issues.
Note if you are scanning satellites the scan will scan both H and V polarities and block any users on V. You can set the antenna setting to V only to stop this, if the channels are all on V that you watch and scan.

This splitter is for both UHF TV band and satellites 5-2400MHz, one for 950-2400MHz is just for satellite. You can use either, but not one that is 5-850MHz as that is for UHF TV only.

Thank you Feralkiwi
You have helped me a lot. Now, I will have to set the decoder in one polarity, prefer V, for not usses. I think that Operator company, use to in one polarity for install very decoders at home. Also will use splitter 5-2400Mhz.

Ya te comenté que no tendrás ningún problema siempre que te muevas con la misma polarización y tono cuando los Decos estén encendidos
Tampoco hagas caso si te dicen de desactivar la alimentación LNB, siempre es mejor usar un distribuidor de prioridad

Muchas gracias CAJE
Tomo nota, entonces no hay riesgo de sobrecarga, que era lo que temía.
Lo que no entiendo es lo del tono

La corriente es aproximadamente de 0,09 A el LNB si la comparas con la fuente de alimentación de 1,5 A del deco es insignificante, también tienes que saber que en el sintonizador el regulador tiene una protección que impide que entre voltaje como también lo hacen los BAT.

El tono es de 0 Khz 22 khz que hace como un conmutador, si está con 0 khz el voltaje será de 13 V y cuando emita un tono de 22 khz el conmutador cambiará y aportara 18 V

I have not seen a switch that changes output voltage with 22kHz tone, 0Hz / 22kHz.

There are switches that have two inputs, one for 0Hz and the other for 22kHz, tone "ON".

The 22kHz tone was the first method for using a switch on satellite boxes.
They then added DiSEqC that uses the 22kHz tone as the digital transmission to the switch, passing switch commands as a data stream by turning the 22kHz on / off.
22kHz tone is also used to change between the lower and upper bands on some LNB's like a universal Ku band of 9750/10600, tone on for the upper band on 10600. These LNB's can be set for only the upper band as 10600 LNB and 22kHz "ON".

In case you have brought a switch like this below, the 22kHz tone is used for the LNB's connected to the 22kHz ports and works with both H and V (18v and 13V). Each port is only for that setting H only and 0Hz, V only and 0hz etc.

Most users now use DiSEqC 2, 4 or 8 port switches.
A 22kHz tone switch can not be use before a DiSEqC switch in the LNB cable as it will switch with each data bit sent to the DuSEqC switch. 22kHz switches are used last and can not be use before a universal LNB as they use the 22kHz tone for band change.
I had some issues when I first started with satellite after I brought a tone switch and the LNB's I had were a twin satellite LNB that used 22kHz to switch between satellites on the same dish. When I switched to the second dish, I also switch to the second satellite on the LNB and it did not work.

Me refería al LNB con su conmutador interno

Satellite frequency band splitters contain diodes that prevent power from passing through to other units. This allows power to be delivered from the box to the LNB with an "All Ports Power Pass". To get more information about this then you can also contact me on JTWhatsapp , which I install it GBFunda ,. I will do my best to guide you.
