Modulator is connected directly to the transmitter IF connector. Router provides 24 VDC power supply to the
transmitter and 10 MHz reference signal. UHP-200 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 and then gets restarted. If power supply is switched on in the configuration, restarts
continue at 5 seconds interval until short circuiting is removed.

RESET button
Router reset is provided using this button. Also, using special combination of pressings this button allows router
reset to factory settings.

IF switch inputs (RX1 and RX2)
UHP-200 router can be connected to one or two LNB via respective inputs of the built-in IF switch. These inputs are
software-switchable to any of the demodulators (See Figure 4). Each of the interfaces can power attached LNB
with 13 or 18 VDC. 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 the 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.
The RX2 input of the router can supply 10 MHz reference signal, which is required for PLL LNB with an external
reference signal. When the reference signal is off the router will not distort reference signal arriving at the router
from the outside.

“SYSTEM” Indicator
“SYSTEM” indicator indicates the router operation mode. This indicator is always flashing. If it does not flash it
means that the router is not functioning (please check power supply). Slow flashing (once every second) means
router normal operation. Faster flashing (3 times every second) means that a Telnet remote control session is
established (in this case USB console does not operate until session is over).
Fast (6 times every second), simultaneous flashing of “ERROR” and “SYSTEM” indicators means that the router is
functioning with the factory default configuration. Access to the router in this mode is possible either via USB of
via IP-address 192.168.222.222 (mask 255.255.255.248 or /29).
1.5.11
“ERROR” Indicator
“ERROR” indicator makes it possible to infer about problems in the router functioning. The type of the generated
problem can be judged by the number of indicator flashes:
1 – Demodulator cannot receive SCPC or TDM channel from the other station or the Hub. Please check AGC value
in the demodulator statistics to determine whether there is a signal from antenna (see description of reception
problems) to separate LNB and cable faults.
2 – Router cannot receive TDMA configuration from the HUB (TDM/TDMA network mode). The reason can be in
the non-availability of receive channel from the HUB, CRC errors during reception, wrong configuration of the
Terminal.
