Cable splitter: Understanding Switch diseq the FTA
External switch
There are only two main options, one with most if not all receivers FTA and regular (legacy work) LNB:
22kHz switch, connects 2 LNBs to one receiver
4×1 DiSEqC switch, connects up to 4 LNB receivers.
22khz switches, these are really easy to see from them component video splitter as a splinter, but a simple ON and OFF 0khz 22kHz and are the two component video splitter inputs then a door out to the receiver, if 22kHz is OFF in your receiver connected to component video splitter, the port 0khz , 22kHz, if you have the receiver is connected to the port-22kHz.
This option is to connect 2 LNBs to one receiver.
The switch 22-kHz is Big Brother, is a DTV or 22khz 4×4 switch has four inputs for connecting this switch and two dual LNB hook for as many as 4 receivers.
2 inputs are labeled 13V, 18V & 0khz, 0khz (remember the LNBF switch inside), and the other two inputs 13V, 18V and 22kHz, 22kHz. This allows both polarities of each LNB to the inside component video splitter of the switch are at any time, and that each access to any receiver on a four polarities of the two LNBs.
These switches in a 4×8 for up to 8 receiver hook ups to 2 component video splitter, satellites to come.
DiSEqC is a pulse, also uses a 22kHz signal but uses a single pulse on the switch to a set of 4 diseq ports, the switch in 2×1 and 4×1 models are available in 2 or 4 LNBs to one receiver LNB A receiver, or may not be used for more than one recipient, you must use a different diseq Go for a second receiver.
DiSEqC-1 or 2 or 3 and 4, component video splitter, the menu, DiSEqC switch, causing the switch port numbered, some receivers use A, B, C, D, instead of 1, 2, 3 4
This “pulse” is sent only once when the switch is too far from diseq receiver can not change fail and doors, sometimes back and forth between the channels of passage can be done to make the change, the ‘pulse is repeated each time you change channels, but moving the switch closer to the receiver can improve its performance.
DiSEqC = Digital Satellite Equipment Control, this was designed for FTA receivers.
DiSEqC in two main versions, committed (1.0) and unbound (1.1) are also involved 2-way (2.0) and tied two-way (2.1).
Committed (1.0) switches are the most common and which are equipped with receivers.
These switches require FACTORY software in your FTA is working properly, 1.0 means that the receiver can operate Committed switches only, 1.1, this means Committed and uncommitted can operate switches, 1.2 means the committed and uncommitted DiSEqC motor can run more.
2.0 is the same as above, 2.0, 2.1, 2.2, but the receiver can also receive information from step 2.0 of the control pulse turns off the receiver, then change the doors, then return a confirmation to the recipient, if a 2.0 receiver does not receive email confirmation that the DiSEqC pulse again and again, to confirm the option is on the right door.
Place two DiSEqC Committed switches on one cable is a no-no, we are so committed and uncommitted types of switches, a dedicated switch on the front line (DiSEqC pulse comes from the receiver so first would be the closest to the receiver), then can pass a switch port is not bound Committed Committed to switch to switches uncommitted ignore commands.
Dedicated 4×1 switches component video splitter are about component video splitter $ component video splitter, 20, not committed about $ 80 4×1 switch, is because you must have 16 LNB connected to a receiver to stick with dedicated switches.
There is no switch for multiple receivers Legacy diseq (regular) style LNBs
switch diseq 22kHz and switches can work well together, with one exception, a 22kHz switch must come after the switch diseq component video splitter ’s.
So you can mount 22kHz switch to two LNBs then hook the output switch to go from 22 kHz on port 1 component video splitter of the diseq ‘. So instead of 4 component video splitter, LNBs you could have a link to 5 LNB, you can Add a 22kHz switch to each DiSEqC port for a total of 8 LNB to connect to a receiver.
Dishnet Legacy switches are called SW, SW21 sw64 like or do not use this is not true DiSEqC pulses so work with FTA receivers.
Legacy TWIN and QUAD LNBs have switch SW so that it does not work with FTA Receiver
DishPro Twin or Quad LNB has an internal DiSEqC switch, so that each port on the LNB has access to one of 2 LNBs inside, 110 or 119, 119 and DiSEqC DiSEqC 1 = = 2 110, LNB require a DP Channel List.
are DishPro external switches, there is now a two DP34 and DPP44, both use DiSEqC pulses so true will work with FTA receivers but you must use DP LNBs to take advantage of the multiple receiver aspect component video splitter of this option.
(Not the LNB DPPlus works with FTA receivers, do not really use DiSEqC)
If you connect a standard (non-DP) LNB to a DP switch and more than one receiver you component video splitter, can only get 1 polarity at a time from that LNB. If you connect a receiver only because he was generally working well. I have not been component video splitter, tested.
more receiver switches
If you use standard (non-DP) LNBs you need is a LNB port per receiver, it is easier when you have a dual LNB has two ports so you can connect component video splitter 2 receivers, if you want to have a receiver connected to the third need a third LNB port.
Single-Output (non-DP) LNBs can always be used with a receiver.
But if component video splitter you have a dual LNB you can expand 4 or 8 or 16 outputs.
This is done with a multi-switch, they come in 3×4, 3×8 component video splitter, and 2×16.
You run two cables from the Dual LNB for multi-switch is then 4 LNB outputs (or 8 or 16) when two LNB you component video splitter, want, then have two Multi-switch, only one team for each LNB.
The 4×4 switch 22kHz 2 multi-switches in one case, and you can diseq 4×1 Use with the creation of a multi-satellite multi-receiver.
C or Ku-switch is a switch 0/12V voltage Most FTAs do not have this option, but some do not function as a coaxial cable signal 22kHz and DiSEqC, need component video splitter two wires to the switch, the switch 2 input and output, 0volts a port is connected to another port is connected to 12V.
On the back of component video splitter the receiver (GND ground) and 12V (12 volts) which is where the two wires are connected to the switch, and will be a menu option to ON or OFF 0/12V.
