I have two diseqc 4x1 and i read that we can connect them together to get 7 sats !
without using tone switch or relay

first diseqc switch 4x1
port1=sat1
port2=sat2
port3=sat3
port4= second diseqc 4x1

second diseqc
port1=sat4
port2=sat5
port3=sat6
port4= sat7

can we connect two diseqc switch 4x1 together like that?
progdvb doesn't see second diseqc !

Thanks

What type of second diseq? Impossible use same types. Software send command for select port number X and both devices receive this command.

first diseqc 4x1 diseqc switch,3db losses and doesn't specify the type
is that mean he is 1.0?
second diseqc is 4 inb 2.0 switch
so they cant be connected together?
what i got from you that we can connect 1.0 with 1.1 or 2.1
and we cant connect it with 2.0 or 1.0 , right?
Thanks

You can connect 1.1 + 1.0 or 2.0. But afaik impossible use two 1.0/2.0 in this scheme. Both device receive and process same commands.

In any case I am recommend one device with 8-16 ports. 2 devices always slow and less stable. Also not all DVB devices support more one diseq devices.
