Kurzübersicht

Single-cable SRM-580 R80580 multiswitch allows for distribution of DVB-S/S2 signals from one satellite and terrestrial signals (DVB-T, DAB/FM radio). The satellite signals can be distributed by means of dSCR technology (digital Satellite Cable Router), requiring only one coaxial line and satellite splitters to provide the signals to compatible SAT receivers, along with terrestrial signals that can be received by standard televisions and radios.

The programmable SRM-580 multiswitch has two pairs of outputs. Each of the outputs can operate as dSCR OUT (the satellite signals transmitted via one coaxial cable can be split among multiple dSCR/Unicable receivers) and Legacy OUT (for connecting a standard SAT receiver).
Key features
  • Full compatibility with EN50494 standard - Unicable I - 8 UBs (User Bands) from each of the 4 pairs
  • Full compatibility with EN50607 - Unicable II - 32 UBs (User Bands) from each of the 4 pairs
  • Possibility of using receivers supporting EN50607 and EN50494 standards in the same subsystem (8 x EN50494 + 24 x EN50607)
  • Static mode: IF/IF converter
Single-cable SRM-580 R80580 multiswitch allows for distribution of DVB-S/S2 signals from one satellite and terrestrial signals (DVB-T, DAB/FM radio). The satellite signals can be distributed by means of dSCR technology (digital Satellite Cable Router), requiring only one coaxial line and satellite splitters to provide the signals to compatible SAT receivers, along with terrestrial signals that can be received by standard televisions and radios. The SRM-580 R80580 multiswitch fully supports receivers operating in two dynamic modes: SCR (Unicable I - 8 User Bans) and dSCR (Unicable II - 32 User Bands).
The SRM-580 multiswitch has 5 inputs (four polarization/band pairs (VL–HL–VH–HH) plus passive terrestrial TV) and 4 pairs of outputs: dSCR OUT (each allowing for independent operation of up to 16 SAT dSCR receivers/STBs fed via one coaxial cable - EN50607 standard) or operating as Legacy OUT (typical SAT output like in Universal LNBs or standard (legacy) multiswitches for connecting a legacy SAT TV receiver).
By default, all outputs of the SRM-580 R80580 multiswitch are configured as Legacy (controlled by 14/18 V and 0/22 kHz commands from SAT receivers). Any output switches to Unicable dynamic mode after receiving DiSEqC command compliant with EN50494/EN50607 standard. This means that each individual output can feed via a single coaxial cable and satellite splitters up to 16 receivers (EN50607).
The device can operate in two modes;

  • DYNAMIC - fixed output frequencies (User Bands) allocated for individual dSCR/Unicable receivers (distribution via single coaxial cable to up to 8 (EN50494 - UNICABLE I) or 32 (EN50607 - UNICABLE II) receivers);
  • STATIC - fixed input and output frequencies, IF/IF conversion allowing for distribution of signals from 32 satellite transponders to an unlimited number of receivers.
The programming of dSCR multiswitches is performed by the dedicated PC102W R80561 programmer.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.
Similarly to other multiswitches, the signals to the SRM-580 multiswitch should be fed from QUATRO LNBs.
The multiswitch should be powered from an external power supply, e.g. PS202F R71468 (20 VDC, 2 A).

The table shows the default settings of the SRM-580 R80580 multiswitch (operation mode - DYNAMIC, 16+16 User Bands, Bandwidth, Level), which can be modified by the dedicated PC102W R80561 programmer.
There are many models of satellite receivers available on the market today. Not all of them support SCR/UNICABLE system compliant with EN50494 and/or EN50607 standard. In the case of implementing solutions based on the standards, all receivers that will be used by subscribers must support SCR/UNICABLE technology. A list of popular satellite receivers available on the Polish market and supporting single-cable multiswitches is provided below:
