Details

The SRM-523 R80523 programmable multiswitch is equipped with two dSCR/Legacy outputs + Terr. TV Out. The single-cable dSCR mode allows independent division of up to 32 SAT STB receivers using two coaxial cables (up to 16 receivers from each output, 16+16 default configuration) or one coaxial cable (32 receivers from one output, after reprogramming with the PC102W R80561 programmer) for each pair. The output in Legacy mode (regular output, as in a Universal LNB or in classic multiswitches) allows connection of a classic satellite receiver.

The SRM 523 R80523 pass-through multiswitch is a device that allows distribution of DVB-S/S2 signals from a single satellite position, DVB-T terrestrial TV and analogue/DAB radio via a single coaxial cable based on digital channel stacking technology. The SRM523 R80523 pass-through multiswitch has full support for receivers operating in two dynamic modes: SCR (Unicable I - 8 User Bans) and dSCR (Unicable II - 32 User Bands). The available output digital signal delivered to end receivers using satellite taps operating in the 5-2400 MHz band. It is equipped with five inputs (four polarisation/band pairs (VL-HL-VH-HH) plus active RTV path) and two dSCR/Legacy outputs. The single-cable dSCR mode allows independent division of up to 32 SAT STB receivers using two coaxial cables (up to 16 receivers from each output, 16+16 default configuration) or one coaxial cable (32 receivers from one output, after reprogramming with the PC102W R80561 programmer) for each pair. The output in Legacy mode (regular output, as in a Universal LNB or in classic multiswitches) allows connection of a classic satellite receiver.

By default, all outputs of the SRM-523 R80523 multiswitch are configured in Legacy mode (the receiver sends a control signal for this purpose: supply voltage 14/18 V, switching signal 0/22 kHz) and switch to Unicable as soon as it receives a DiSEqC command compliant with the EN50494/EN50607 standard (dynamic mode). This means that each of the two outputs of the multiswitch can split the signal to up to 16 receivers using a single EN50607 standard coaxial cable.

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 one coaxial cable up to a maximum of 32 tuners. 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.

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 SRM523 R80523 multiswitches 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 default settings of the SRM-523 R80523 multiswitch (operating mode, User Bands 16+16, UB bandwidth, output level) can be modified with the use of the dedicated PC102W R80561 programmer.

Key features:

fully compliant with EN50494 - Unicable I, 8 UB - User Bands (8 channels)
fully compliant with EN50607 - Unicable II, 32 UB - User Bands (32 channels)
one pair of outputs (2xdSCR/Legacy) and one processor
it is possible to mix receivers supporting EN50607 and EN50494, in the same network (8 x EN50494 + 24 x EN50607)
the built-in AGC circuit - corrects the signal amplification accordingly, so that a constant signal level of 84 dBμV is provided at its output. This means that the installer does not have to worry about signal correction on the multiswitch - he only has to take care of proper signal level on the input of the device
active RTV path
in dynamic mode it enables signal distribution to up to max. 32 receivers
in static mode works as IF/IF converter

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:
