Terra Unicable SRM522 dscr Profi Multischalter

The single-cable SRM-522 multiswitch is compatible with:

a quatro LNB - the four satellite inputs are connected to four signals polarization/band (VL–HL–VH–HH), the fifth is the input of passive terrestrial TV/radio path;

a wide band LNB - the four satellite inputs are used as two pairs connected to SAT IF signals within 290...2340 MHz range, the fifth is the input of passive terrestrial TV/radio path.

The programmable SRM-522 multiswitch has two SAT IF outputs (dSCR1 DC IN and dSCR2 Legacy, 950...2150 MHz ) allowing 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, after reprogramming with the PC102W R80561 programmer). The dSCR2 Legacy output can be in Legacy mode used as a typical SAT output (like in Universal LNBs or standard (legacy) multiswitches) for connecting a legacy SAT TV receiver).

Notice! The Legacy output is operable only with a quatro LNB.

Key features

Signals from a Wideband LNB are fed only via two cables (one satellite) or four cables (two satellites)

Compatibility with quatro LNBs (after reprogramming with PC102W programmer)

AGC system ensures stable 84 dBμV output level

Full compliance with EN50494 - Unicable I, 8 UBs (User Bands)

Full compliance with EN50607 - Unicable II, 32 UBs

Possibility of using receivers compliant with EN50607 and EN50494 in the same distribution network (8 x EN50494 + 24 x EN50607)

Static mode: IF/IF converter

Dynamic mode: distribution of signals to up to 32 receivers

SRM522 R80522 cascadable single-cable multiswitch allows for distribution of DVB-S/S2 signals from one satellite and of 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 SRM522 R80522 multiswitch fully supports receivers operating in two dynamic modes: SCR (Unicable I - 8 User Bands) and dSCR (Unicable II - 32 User Bands). The multiswitch has 5 inputs. Two pairs of SAT IF inputs (V1, H1, V2, H2, 290...2340 MHz) should be connected to two A98222 Wide Band LNBs or to quatro LNBs, the fifth input is intended for terrestrial signals (DVB-T, DAB(+) and FM radio). Two SAT IF outputs (dSCR1 DC IN and dSCR2 Legacy, 950...2150 MHz ) 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, after reprogramming with the PC102W R80561 programmer). The dSCR2 / Legacy output can be used as typical SAT output (like in Universal LNBs or standard (legacy) multiswitches) for connecting a legacy SAT TV receiver).

By default, the SRM522 R80522 multiswitch is configured in dynamic mode, with dSCR OUT operating as Unicable port and Legacy OUT as universal (legacy) port that switches into Unicable mode after receiving DiSEqC command from a receiver/STB (compliant with EN50494 or EN50607 standard). It means that each of the two outputs of the multiswitch can independently feed up to 16 receivers (in the EN50607 standard). The digital signals should be split among the receivers with the use of satellite splitters operating in 5-2400 MHz band.

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.

SMATV systems based on SRM522 multiswitches should be fed from Wideband or quatro LNBs.

The multiswitch should be powered from an external power supply, e.g. PS202F R71468 (20 VDC, 2 A).
