Terra Unicable SRM584 dscr Profi Class A Multischalter

The programmable SRM-584 multiswitch has four pairs of Legacy /dSCR + DTT outputs. In dSCR mode, the outputs allow 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).

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.

The single-cable cascadable SRM-584 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-584 R80584 multiswitch fully supports receivers operating in two dynamic modes: SCR (Unicable I - 8 User Bans) and dSCR (Unicable II - 32 User Bands).

The SRM-584 multiswitch has 5 inputs (four polarization/band pairs (VL–HL–VH–HH) plus active terrestrial path (DTT)) and eight 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-584 R80584 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 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 (20 VDC, 2 A).
