The programmable SRM-564 R80564 multiswitch has three pairs of Legacy /dSCR +DTT outputs. The single-cable dSCR/Unicable mode enables distribution from each pair of up to 32 independent satellite channels (Unicable II) plus terrestrial signals with the use of ordinary satellite splitters operating in the 5-2400 MHz band.
• Multiswitch designed to work with Unicable I/II receivers
• Number of outputs: 6xdSCR/Legacy
• Built-in AGC in RTV/SAT circuit
• Built-in LNB switch for selecting wideband or quatro LNB - reduced number of input cables
• 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 3 pairs
• Possibility of using receivers supporting EN50607 and EN50494 standards in the same subsystem (8 x EN50494 + 24 x EN50607)
• In dynamic mode, allows to split signal do max. 32 receivers

Details

The programmable SRM-564 R80564 multiswitch has three pairs of Legacy /dSCR + DTT outputs. The outputs allow in dSCR mode for independent operation of up to 32 SAT dSCR receivers/STBs, fed in via two coaxial cables (16+16, default configuration) or via one coaxial cable (32 from one output in Unicable II standard, after reprogramming with the PC102W R80561 programmer) and through a distribution network based on typical passive satellite taps and splitters operating in the 5-2400 MHz frequency range. In Legacy mode, each of the outputs can be used as typical SAT output (like in Universal LNBs or standard (legacy) multiswitches) for connecting a legacy SAT TV receiver).
The single-cable cascadable SRM-564 R80564 multiswitch allows for distribution of DVB-S/S2 signals from one satellite (or, using wideband LNBs, from two satellites) 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 cascadable SRM-564 R80564 multiswitch fully supports receivers operating in two dynamic modes: SCR (Unicable I - 8 User Bans) and dSCR (Unicable II - 32 User Bands).
The SRM-564 multiswitch has 5 inputs (four polarization/band pairs (VL–HL–VH–HH) plus active terrestrial path (DTT)) and six outputs: dSCR (each allowing for independent operation of up to 16 SAT dSCR receivers/STBs fed via one coaxial cable - EN50607 standard) or operating as Legacy (typical SAT output like in Universal LNBs or standard (legacy) multiswitches for connecting a legacy SAT TV receiver).
The built-in Automatic Gain Control (AGC) appropriately adjusts the multiswitch gain to ensure preset, constant output signal levels.
By default, all outputs of the SRM-564 R80564 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 5-2400 MHz 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 practical limit results only from the attenuation of the passive distribution network).
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.
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-564 R80564 multiswitch (operation mode - DYNAMIC, 16+16 User Bands, Bandwidth, Level), which can be modified by the dedicated PC102W R80561 programmer.
Key features
  • Built-in LNB switch for selecting wideband or quatro LNB
  • Six (three pairs) dSCR/Legacy tap outputs
  • DISEqC control connector allowing for connecting PC102W R80561 programmer and simultaneous configuration of all outputs
  • 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 3 pairs
  • AGC system ensures stable 84 dBμV output level in the SAT path and 82 dBμV level in the terrestrial path
  • Possibility of using receivers supporting EN50607 and EN50494 standards in the same subsystem (8 x EN50494 + 24 x EN50607)
  • Power supply diagnostics by means of LEDs located on the device housing
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. As an example, a list of popular satellite receivers available in the Polish market and supporting single-cable multiswitches is provided below:
