The position indicator switch makes easier the installation of the device verifying the compatibility of the receiver with the multi-switch. Normally a receiver with DiSEqC carries the installation of 4 LNCs, this 4 LNCs usually correspond to four different satellites with their four corresponding bands. The eight first inputs of the multiswitch can be controlled by the means of Toneburst protocol analogical signal, the next 8 inputs can only be programmed by the means of DiSEqC.

In order to verify the compatibility and make a correct installation we must follow the following steps:

1.- The system must be fed by and connected to LNCs.

2.- The satellite receiver must be connected to the output “Out 2” of the multiswitch and it is advisable to connect a Tv to the receiver in order to verify the correct running of the system.

3.- The switch must be in “Mode 1”.

4.- If the receiver has DiSEqC, it will recognize the 4 LNCS by the means of DiSEqC command.

5.- In the display that the multiswitch incorporates it could be verified that the tuned band in the receiver corresponds to a fixed input, since it shows all the time the satellite input that the receiver is communicating to.

6.- Once the installation is finished, we must put the switch in the “Off” position.

 
 
 

This helping system in the installation allows the installer to identify in each cascade multiswitch all the cables that are in the input. It provides the correct position of the cable that we want to connect at any time, by the means of the display of the multiswtich. In order to make a correct use of this system you must follow the following steps:

1.- Verify the status of the power supply’s led of the headend cascade multiswitch. If the light of the LED is fix, the device is running correctly, if on the contrary it is flicking or the LED is off, it indicates that there is a short-circuit or that the feeding of the device is overloaded.

2.- Connect it to the headend cascade multiswitch output.

3.- Turn the small switch of the indicator of position to the position “Mode 2”.

4.- Try to connect the main cables that come from the headend one by one tothe multiswitch terrestrial signal input. The moment when a “0” appears in the display, it will show the terrestrial signal cable.

5.- Once the terrestrial signal cable is correctly connected, we have to select another downlink and connect it in the first multiswitch satellite input. The display will show which the correct input of the cable is.

6.- Repeating the last instruction until we have all the satellite signal cable connected. If during the process of installation, when connecting a cable the position of the display got erased, keep this cable aside and connect it once the remaining cables are fixed in their correct position.

7.- The process for installing the resting multiswitches of the installation is the same.

8.- In the case where we have to install a cascade line amplifier, it has to be placed just before the input or just after the output, depending on the function (pre or post amplifier). Each single path of the amplifier allows the direct current to go through, from the input to the output.

9.- The small connection cables between the amplifier and the multiswitch can not be crossed.

10.- If the display shows a mark after having fixed it correctly, it is possible that one of the cables has a short-circuit.

11.- In the last cascade multiswitch, the main outputs have to be ended with charges of 75 Ohms. If at the moment when the endings are connected a “0” appears, it will be necessary to check this output because it is possible that it has a short-circuit.

12.- After completing the installation, we must fix all the switches of the multiswitch in the “Off” position.
