EASTAR UHP-1000 SERIES SATELLITE ROUTER

INSTALLATION AND OPERATION MANUAL, V. 2.3

(SW VERSION 2.2.9)

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) and continuous (SCPC/MCPC) carriers from the satellite in

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.

1.2.8 Modulator output (TX OUT)

TX OUT output can feature 24 VDC with a high short-circuit current. Short

circuiting can cause sparkle spread and burns. This voltage can damage

measurement equipment if it is not protected at its inputs. Supplying

external voltage to this connector is objectionable and supplying more than

24 V is prohibited.

UHP-1000 modulator is compatible with most satellite transmitters/converters (BUC). Those

incompatible are only transmitters that require to explicit ―TX On‖ FSK command but such

transmitters are extremely rare and are not widely employed.

Modulator is connected directly to the transmitter IF connector. Router provides 24 VDC

power supply to the transmitter and 10 MHz reference signal. UHP-1000 is not provided

with a separate protection on the transmitter power supply circuitry. Use is made of current

protection for the power supply adapter. In case of a short circuit the router is de-energized
