Details

The SRM-524 R80524 programmable multiswitch is equipped with 1 pair of dSCR/Legacy outputs + Terr. TV out. The single-cable dSCR/Unicable mode enables independent splitting of the RTV/SAT signal using common satellite splitters operating in the 5-2400 MHz band according to the Unicable II standard to up to 32 satellite receivers for one pair. By default, each output of the multiswitch from a given pair is programmed in a configuration allowing the division of the RTV/SAT signal to 16 receivers. Each of the multiswitch outputs can be reprogrammed using the PC102W R80561 programmer. The output in Legacy mode (regular output, like in a Universal LNB or classic multiswitches) allows to connect a classic satellite receiver.
The SRM-524 R80524 pass-through multiswitch is a device that allows to distribute DVB-S/S2 signals from one satellite (two satellite positions after using wideband converters), terrestrial DVB-T and analog/DAB radio based on digital channel stacking technology. The SRM-584 R80524 pass-through multiswitch has full support for receivers operating in two dynamic modes: SCR (Unicable I - 8 User Bands) and dSCR (Unicable II - 32 User Bands). It is equipped with 5 inputs (four polarisation/band pairs (VL-HL-VH-HH) plus an active TV path) and 1 pair of outputs: dSCR Out (allowing independent division of the RTV/SAT signal to max. (for independent splitting of the RTV/SAT signal to up to 16 receivers using satellite splitters operating in the 5-2400 MHz band for each of the 2 outputs according to the EN50607 standard) /Legacy Out (normal output, as in a Universal-type converter or in classic multiswitches used for connecting a classic satellite receiver). Included AGC circuit (Automatic Gain Control) appropriately corrects the amplification at the multiswitch's output to ensure a constant, preset signal level.
By default, all outputs of the SRM-524 R80524 multiswitch are configured in Legacy mode and switch to Unicable as soon as they receive a DiSEqC command compliant with the EN50494/EN50607 standard (dynamic mode). This means that each of the two outputs of the multiswitch for 1 pair can independently split the signal to up to 16 receivers using satellite taps operating in the 5-2400 MHz band according to the EN50607 standard.
The device can operate in two modes:
  • dynamic mode (DYNAMIC) - the output frequencies are fixed and each is assigned to a receiver (User Bands), signal division using satellite splitters up to a maximum of 32 receivers (for each of the four pairs). The receivers must comply with EN50494/EN50607 (UNICABLE I/UNICABLE II).
  • static mode (STATIC) - both input and output frequencies are fixed, works as an IF/IF converter allowing distribution of signals from 32 satellite transponders to an unlimited number of receivers (limitation is exclusion of passive components in the installation).
The programming of dSCR multiswitches is performed by the dedicated PC102W R80561 programmer.
The cast housing provides a high shielding effect that prevents interfering signals from penetrating inside the unit.
The multiswitch requires an external power supply, such as PS202F 20 V 2 A R71468.
The table shows the default settings of the SRM-524 R80524 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 to change videaband/quatro converter
  • number of taps - dSCR/Legacy mode: 2 (1 pair)
  • connector DISEqC control enabling connection of PC102W R80561 programmer and simultaneous configuration of all multiswitch outputs
  • built-in AGC circuit - appropriately corrects the signal amplification, so that the multiswitch outputs provide a constant, preset level; automatic equalization of signal levels up to 84 dBμV in the SAT path and 82 dBμV in the RTV path
  • power supply diagnostics via LEDs on the housing
  • fully compliant with EN50494 - Unicable I, 8 User Bands (8 channels for 1 pair)
  • fully compliant with EN50607 - Unicable II, 32 User Bands (32 channels for 1 pair)
  • it is possible to mix receivers supporting EN50607 and EN50494, in the same network, on each output (8 x EN50494 + 24 x EN50607)
There are many models of different satellite receivers on the market today. Not all of them support the SCR/Unicable system in accordance with EN50494 or EN50607. The prerequisite for the use of SCR/UNICABLE technology is its implementation in the receiver. List of available satellite receivers that support single-cable multiswitches:
Ferguson receivers:Cyfrowy Polsat receivers:
  • HD 5000 decoder
  • HD 5500s decoder
  • EVOBOX PVR
nc+ receivers:
  • BOX+
  • mediaBOX+
  • turboBOX+
  • wifi Premiumbox+
  • UltraBox NC+
