    Default DiSEqC and 22k tone switch setup



    I am currently using a Humax 5410z decoder which allows for a maximum of 8 satellites dish lnb antennas, using a combination of 22k and diseqc switches.

    My current dish setup is configured like the following.



    The cheapest way to add additional satellites to my configuration would be to purchase another 4 way diseqc switch and run the 2 Diseqc switches through a single 22k tone switch to get the extra satellites. Just wondering if this will work?



    Or will I need to go the more expensive route and purchase additional 22k switches like the following setup?

    Can't see why this won't work. Your best option methinks.
    Would require all port pass switches for H & V Polarity.

    tone burst and 22khz are 2 different types of switching

    If you used tonebust you can use universal lnbs, if you use 22khz you will not have all the bands available to you

    This is the 22k switch I have used. I hope this makes things a lot clearer

    Thanks for that. So Im just using a basic 22k switch. This means I should not connect any Universal LNBS. If so then they will not be able to switch between LO 10.7-11.8 and high 11.6 - 12.7 GHz band. Only get stuck on LO band.

    I always thought a tone burst switch was a 22 khz switch.

    Anyone care to explain to me what ive misunderstood?

    Edit; Ok google showed me my confusion.

    yes correct, the result would depend on what port you put the universal lnb on

    So if I put the 22k Switch first and then put all the universal LNBS on diseqc connected to the OFF port on the 22k switch then they should be ok to run in both high and low band? Its just the 22k ON side that will cause problems with universal LNBs using this switch

    nah, a universal lnb uses 22khz to swtich between high and low band

    if you used a tone burst switch before your disecq then it would work no problems

    That is not the only way it works.
    They happily co-exist in any order.
    This from their site clarifies their intended operation.

    Strange because in the manual for my decuader it states

    LNB Frequency
    When you select universal, both 9750 and 10600mhz are supported at the same time. 22KHz tone setting is unnecessary. (Disabled).

    I just assumed this would be the same as selecting 22KHz off (0KHz).

    Otherwise what your saying is just stick with 22k switches on each Diseqc port for the single LO Frequency lnbs and then leave the universal LNBs on seperate Diseqc ports without 22k switches.

    It's immaterial. Look at the timing on my previous post and you will see that they are independent and can be used together.
    The tone burst is sent within the ~93 ms spaces in the steady 22KHz tone. The later switches/LNB see this as an uninterrupted 22KHz ON or OFF.
    In other words, it doesn't matter where you put them.
