1.5.2
Power connector (DC IN)
UHP-1200 router is powered with 24 VDC. AC/DC Power supply adaptor is not supplied. The router can be
powered from different DC power sources (batteries, DC-DC converter). The router can provide power to RF
hardware within the current according to the specifications of the router.
1.5.3
LAN interface connector
LAN connector is purposed for connecting to Ethernet switch using a straight cable. Bit rate 10 or 100 and duplex
mode are software selectable.
1.5.4
IF Rx input
This interface is intended to connect the router to the LNB. The received signal via the built-in splitter (see Figure
4) is fed to a DVB and TDMA demodulators of the router. The input, on the router side, can be fed with 18 VDC
power supply. Whether power source in on or off, the input can withstand external voltage up to 50 VDC (power
supply circuit is provided with a diode). 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.

UHP-1200 modulator is compatible with most satellite transmitters/converters (BUC). Modulator is connected
directly to the IF Tx connector. The router provides 24 VDC power supply to the BUC and 10 MHz reference signal.
UHP-1200 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.
