Anonymous | have 2 dual sats pointed at 110 and 119 hooked up to 2 recievers using diseqc sat 4x1 switches. Have one coax cable coming from each sat going to the switch with the proper switch numbers on the setup menue on the reciever. My problem is when one reciever changes channels the second reciever loses its signal. Once you change channels on the second reciever the signal comes back. Also on some echo 9 channels reciever 1 has to be on a channel on echo 9 for the 2nd reciever to get that channel. I don't understand what is going on. bad switches? dish pointing? |

try this Unregistered guest | I don't know if this is the expert way to do it, but I have two cables coming from each sat(dual lnbs) going into 2 separate diseqc switches. Each diseqc then runs one wire out to the receiver. |

|
still in need of help Unregistered guest | That is what I have. One cable from each sat going to one switch then one cable from that switch going to one reciever. So I have two switches, one for each reciever |
|
Anonymous | the switch I have allows for 4 LNBs it is a diseqc 20. Your saying it is not the right one. |

Bronze Member Username: SpankPost Number: 20 Registered: Oct-05 | Sorry, not that one specifically but it is a 4 X 4 that I think you need. The link above is for direct not dishnet. |
|
thank you Unregistered guest | thanks i try one and see what happens |

Anonymous | NEED A DISQUE 4 (lnb'S) X 2 (RECEIVERS)..THEREBY DISQUE 4X2 |

Bronze Member Username: Thill1951akalkPost Number: 97 Registered: Oct-05 | Beginners guide to switching -------------------------------------------------------------------------------- This document is directed to novice,and slightly experienced hobbyists.Its purpose is to help those in need of answers to basic switching setups;It is not directed to those involving 2 or3 types of LNB's to 5 receivers...you should already be blueprinted. Ok,lets start at the beginning..the very beginning.When you enter the switch forum,scroll down to the bottom left of the page.You will see "display options".Where you see "last month" boxed with a down arrow,view the other options and select "beginning",and then select "show threads".This will be your next destination after you have read this basic setup document....read carefully. You must determine your setup and gear.Here we will try to get you started with the most efficient and reliable switches. One LNB to one receiver..............no switch needed One LNB to two receivers...............no switch needed(requires a DUAL output LNB) Two LNB's to one receiver............This can be done with any one of the following; AB switch/2x1 diseqc/4x1 diseqc/22Khz switch/4x4 multiswitch (1) A/B switch from wallyworld or Ratshack;works great,switches every time...you will need 2 cables run to switch. (2) 2x1 diseqc switch;works reasonably well;antennae settings must coincide with switch inputs. (3) 4x1 diseqc switch;Probably the most widely spread and unreliable switch on the market.Performance level is abysmal.Does NOT like 2 different types of LNB,long cable runs,water,humidity,or anything else.Best brand by far for a good price is Chieta,and Spaun for high end...better be for the money. (4) 22Khz switch; Very reliable tone switch.Easily installed and reasonably priced.One line from each LNB to switch,and one line out to receiver.Highly recommended. (5) 4x4 multiswitch; Very versatile switch that requires dual LNB's.It can drive up to 4 receivers,and is 22Khz operated as well.These were around in the old D*V days and have an excellent track record and are highly recommended. Two LNB's to two receivers..........This is where multiple switches is required in 3 of 4 examples. (1) 2x1 diseqc switch;2 required for this installation,as well as 2 dual LNB's.The outputs from each LNB will go to a separate 2x1 switch,and from switch to receiver. (2) 4x1 diseqc switch;2 required for this installation,as well as 2 dual LNB's.The outputs from each LNB will go to a separate 4x1 switch,and from switch to receiver. (3) 22Khz switch; 2 required for this installation,as well as 2 dual LNB's.The outputs from each LNB will go to a separate 22Khz switch,and from switch to receiver. (4) 4x4 multiswitch; 1 required for this installation,as well as 2 dual LNB's.The outputs from LNB #1 will go to Sat A inputs,and the outputs from LNB #2 will got to Sat B inputs.Do not be concerned with the 18v and 13v allocation,as the switch "freezes" these voltages within the unit.Set 1 sat to 22Khz ON,and the other to OFF(in your settings). This unit can drive up to 4 receivers. Three LNB;s to one receiver...........As much as we hate to say so,the 4x1 diseqc switch is the simplest(although not the most efficient) switch for this job.As the cost of these has dropped,so has the quality. Four LNB's to one receiver..........Again,reluctantly,the 4x1 diseqc is the simplest choice. Two LNB's to three receivers..........4x4 multiswitch Two LNB's to four receivers............4x4 multiswitch |

Bronze Member Username: SpankPost Number: 22 Registered: Oct-05 | The LNB on your satellite dish is capable of tuning to a satellite transponder that is broadcasting in either left-hand or right-hand circular polarity. When you tune to a channel on your receiver, the receiver sends a switching signal back up the coax cable to the LNB in the form of a 14-volt or 18-volt DC voltage level to select the correct polarity for the transponder you have requested. This is why you cannot use a splitter for adding additional DSS receivers. If you do, the LNB gets a conflicting set of commands from the two sat receivers if they both try to access transponders of differing polarity. As a result, you can get a signal on one receiver while not the other if different transponders have been selected by each. A multiswitch is basically a box that contains splitters and A/B switches. The outputs of each LNB are connected to the A and B inputs of the multiswitch. In this configuration, one LNB is dedicated to left-hand polarity transponders and the other LNB is set up for right-hand polarity. The inputs to the multi-switch from the LNBs are split for either 4 or 8 outputs each (more if a larger multiswitch is desired). These split outputs are paired and connected to a series of A/B switches such that one side of the switch sees input A and the other side sees input B. The outputs of the multiswitch are routed to each receiver you have in your household. When you tune to a channel, instead of the LNB being switched to the correct polarity, the 14-volt or 18-volt signal selects either transponder A or B by toggling the A/B switch. The LNBs are no longer switched when you change channels. Instead, the switching occurs inside the multiswitch (hence the name) and the correct polarity is selected for the desired channel/transponder. Note that there are two different types of multiswitches available - passive (unpowered) and active (powered). If you have cable runs longer than 100 feet for any receiver, a powered multi-switch is highly recommended. The long run can degrade the voltage output from the receiver and the multiswitch may not work properly if the voltage drop is too great. A powered multiswitch detects the difference in the voltage levels and compensates for it. |
