Part2: What’s the difference between DiSeqC and multi-dish Switch? For small numbers of receivers a multi-output LNB is used and all the feeds are taken straight from the LNB but there is a limit to the number of outputs that can reasonably be placed on a LNB. This means that each receiver needs a separate feed and twin-tuner receivers (such as sky+ and freesat+) need two separate feeds.

This table shows what works and what does not:Ī multiswitch is a device used with a quattro LNB to distribute satellite TV signals to multiple (usually more than four) receivers from a single dish and LNB.Ī typical Ku band universal LNB can be switched between four modes (two frequency ranges and two polarisations) selected by signals from the receiver (supply voltage for polarisation and presence or absence of a 22 kHz tone for frequency range). 1.x and 2.x versions are both backwards and forwards compatible. The later versions are backwards compatible with the lower revisions, but the lower revisions are, as might be expected, not forwards compatible with the higher revision numbers. DiSEqC 2.2, which adds bi-directional communications to DiSEqC 1.2Īll four variations were standardized by February 1998, prior to general use of digital satellite television.DiSEqC 2.1, which adds bi-directional communications to DiSEqC 1.1.DiSEqC 2.0, which adds bi-directional communications to DiSEqC 1.0.DiSEqC 1.2, which allows switching between up to 16 sources, and control of a single axis satellite motor.DiSEqC 1.1, which allows switching between up to 16 sources.DiSEqC 1.0, which allows switching between up to 4 satellite sources.Despite its name, it has been used on fully analogue or only partially digital-capable (Astra Digital Radio) satellite receivers. DiSEqC is also compatible with the actuators used to rotate large C band dishes if used with a DiSEqC positioner. DiSEqC is commonly used to control switches and motors, and is more flexible than 13/18 volt and 22 kHz tone or ToneBurst/MiniDiSEqC techniques. DiSEqC was developed by European satellite provider Eutelsat, which now acts as the standards agency for the protocol.ĭiSEqC relies only upon a coaxial cable to transmit both bidirectional data/signals and power. Part1: What’s DiSEqC Switch and MultiSwitch?ĭiSEqC(Digital Satellite Equipment Control),pronounced “Die-Sec”, is a special communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small dish antenna rotor. This article has two parts, from it, you’ll have a more clear understanding of DiSEqC and Multi-Switch.
