How to use 22K Satellite Switch in your FTA Set-Top Box?

For example if you have two dish antenna and you are using 4X1 DiSEqC switch in both dish antenna. Then think that how your set-top box will give command to both DiSEqC switches. To resolve this issue, you can use 22K satellite switch to send different-different command to both DiSEqC switches.

By turning the 22 KHz option on & off, or to "0" & "22K" on your receiver, the receiver will automatically switch between the two ports allowing reliable operation that sometimes fails when using a 2X1 DiSEqC switch.


Understand it here:
Dish antenna 1 (22K On)
DiSEqC switches -A
DiSEqC switches -B
DiSEqC switches -C
DiSEqC switches -D

Dish antenna 2 (22K Off)
DiSEqC switches -A
DiSEqC switches -B
DiSEqC switches -C
DiSEqC switches -D

If you do setting like above then your free to air satellite receive can send tone separately in both DiSEqC switches. The 22 KHz switch is used to switch between two devices.  All FTA Set-Top boxes have 22 KHz switching capabilities.  By sending a 22 KHz tone to the switch, the receiver controls the ports.  It can be used as a simple LNB1 / LNB2 switch to switch between two different satellite LNBFs or two different DiSEqC switches. 

This 22K switch easily available on Marginprice or other online websites.
