1.2.6 High-speed demodulator IF input (SCPC RX)

SCPC-RX is one of the two signal inputs to receive signals from the satellite (LNB). This input is designed to receive

continuous (SCPC/MCPC) carriers in DVB-S and DVB-S2 formats from the satellite. The input, on the router side,

can be fed with 13 or 18 V power supply. Whether power source in on or off, the input can withstand external

voltage up to 50 V (power supply circuit is provided with a diode). Short circuiting is not welcome since it creates

high load on the device. Power supply circuit is protected with a thermal fuse operating in case of short circuiting.

After short circuiting is removed it may be required to disconnect load from Rx inputs for several seconds so as to

allow the fuse to return to its initial state.

Cable length and cable quality (losses level) can affect the quality and possibility of receiving signals.

1.2.7 Burst demodulator IF input (TDMA RX)

TDMA-RX is the second input for the signal from the satellite (LNB). This input is designed to receive bursts (TDMA)

in UHP proprietary format. The input can also provide, from the router side, supply voltage 13 or 18 V, similar

voltages being simultaneously fed to both inputs. The router can feed this input with a reference signal for using

PLL LNB requiring external reference signal. When reference signal is switched off the router will not distort

reference signal arriving at the input from outside. The rest conditions are similar to those across SCPC RX.

THE TOTAL CURRENT CONSUMED BY EXTERNAL EQUIPMENT THROUGH BOTH RX INPUTS SHOULD NOT BE IN EXCESS OF

750 MA. NORMALLY, CURRENT CONSUMPTION BY DRO LNB - 150 MА, PLL LNB - 500 MА.
