What is needed is for the first layer ( the 2 way ) to respond first, then the second layer, so any of the 8 lnbs can be selected.
In this case if all switches were the same type ( committed ) then it cannot work properly as all switches would respond together. When it is necessary to cascade switches eg Diseqc 1.0 commands are for this type of switch. There are two types of switch available, the usual common one is called a committed switch. This can be useful sometimes, if you ever consider using a Sky box in place of your diseqc compatible receiver ( Sky boxes have no diseqc control built in ) then use the Astra2 ( Uk freesat and Sky ) in diseqc position 1. If the diseqc menu is not set up at all, the satellite connected to port one will come through to the receiver. If you start the scan process and find the channels are not as expected, exit and reselect the diseqc position. Traps for the unwary – if the same frequency is used on 2 of the satellites you are trying to set up, the signal indicator may show ok, when you are on the wrong satellite. When the correct lnb is selected for the satellite indicated in the diseqc menu, the signal strength display will show a signal is present. With an 8 or 16 way switch, select the diseqc 1.1 command menu. The 4 positions are usually numbered but some receivers use ABCD instead
With a 4 way switch, select the diseqc 1.0 command menu. Setting up a receiver to work with DiseQc commands This was further advanced with USALS (Universal Satellites Automatic Location System ) sometimes referred to as diseqc 1.3, which uses the DISEQC commands to select preset positions automatically, without the installer having to program each position. There is a further DISEQC protocol, DISEQC 1.2 which is used to control a motor or positioner which steers a dish to the right angle to receive signals from a satellite. The packages on this website commonly use a single dish to pick up 2, 3 or 4 satellites.Spain2 for example uses a two way diseqc switch and a single dish to give ALL the available free Spanish channels, which are distributed over Hotbird and Astra 1 satellites. The lnbs can be on one dish or several dishes. DISEQC 1.1 allows up to 16 lnbs into one output. Developed by the satellite builders Eutelsat, originally to enable users to switch between the two popular satellites over Europe -Astra and Eutelsats own Hotbird satellite, it was adopted by most set top box manufacturers and is now standard.ĭISEQC 1.0 allows up to 4 lnbs to be switched into one output.
