2. Hardware overview and functions
2.1 Interfaces and controls
Back panel of UHP has connectors for attachment of radio equipment cables, power and USB. It also has reset button.
UHP back view
Power connector (DC IN)
UHP-1000 router is powered with 24 VDC. AC Power supply adaptor is supplied with the set. The router can be powered
from a DC power source (batteries, DC-DC converter), but the specific power supply mode should be agreed upon with
the Manufacturer. Power supply connector features dimensions 5.5 / 2.1 mm (outer and inner diameters). Positive terminal
of the source is on the center contact.
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. Indicators built into the connector mean the following: left one (green) - connection (Link) and data
transmission (Activity), the right one - yellow) - activation of half-duplex mode.
USB Console
The console port provides local control of the device.
RESET button
Router reset is provided using this button. Also, using special combination of pressings this button allows router reset to
factory settings.
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. 18 V DC LNB power can be output
to this connector by UHP. 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). Power supply circuit is protected with a self-recovering 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.
Demodulator of the continuous signals is intended for reception of satellite channels transmitted by another UHP router
only. On the physical level, transmission format complies with DVB-S and DVB-S2 standards but the channel information
filling (encalsulation) is proprietary and incompatible with DVB - there are no PIDs, etc.
To receive signal (carrier) from satellite, it is essential to know at least four parameters:
- The satellite used in the network (antenna should be pointed to this satellite)
- Polarization (proper polarization should be selected on in the demodulator configuration or the receive converter on the
antenna should be turned to the required position if its polarization cannot be switched over using its supply voltage)
- Carrier center frequency (enter its value in the demodulator configuration)
- Carrier symbol rate (enter the value in the demodulator configuration)
Channel frequency conversion
Satellite channel frequencies fall into five bands:
- Ka (24.0 GHz - 31.5 GHz) - frequency at which Ka satellites transmit and receive carriers
- Ku (10.7 GHz - 12.5 GHz) - frequency at which Ku satellites transmit and receive carriers
- X (7.2 GHz - 11 GHz) - frequency at which X satellites transmit and receive carriers
- C (4 GHz - 5 GHz) - frequency at which C satellites transmit and receive carriers
- L (950 MHz -2050 MHz) - frequency converted by the receive converter (LNB) and which is applied to the router's
demodulator input
UHP itself outputs and inputs L-band frequencies. RF equipment attached to antenna - BUC transmitter and LNB receiver
shift frequencies to fit them to ranges accepted by satellite.
UHP Software 3.0 User Manual 7
Document version 1.0, May 2013 7

Frequency conversion
Some BUCs and LNBs (most of C-band LNBs) use special conversion scheme having down-side frequency conversion
with spectrum inversion. Inversion occurs when BUC LO is higher than required TX frequency. TDM demodulator can
automatically detect spectrum inversion. TDMA demodulator cannot detect it itself and will not work if inversion is not
switched on on modulator to compensate BUC inversion.
Frequency conversion with BUC spectrum inversion
Reception of the signal is done by receive converter (LNB). It performs two functions: amplification of the weak signals and
converting them to signals at a much lower frequency called intermediate frequency or IF. When converting the frequency,
frequency of the local oscillator (LO) is subtracted from that of the signal received by LNB from the satellite. LO frequency
of various LNBs can be 10 GHz (professional converters), 0.975 GHz and 10.7 GHz (sat TV converters). LO frequency is
usually written on the converter case label or in its Manual.
There are double-frequency (wideband) converters containing two LOs with different frequencies. These converters are
switched over using frequency 22 KHz. UHP-1000 routers do not support 22 KHz control signals and cannot switch LO in
such converters. If converter switches the LO using voltage of 13/18 V, the router will be capable of switching LO
frequency.
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.
Warning: 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 is 150 mA, PLL LNB - 500 mA.
Modulator output (TX OUT)
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 and then gets restarted. If power supply is switched on in the configuration, restarts continue at 5 seconds
interval until short circuiting is removed. Powering UHP via TX cable with 24V is possible.
UHP Software 3.0 User Manual 8
Document version 1.0, May 2013 8

Warning: Any operations with TX IF cable should be performed with 24 V supply voltage turned off. Otherwise, self-
induction across a long cable can damage the transmitter and/or UHP. TX out output can feature 24 VDC with a high
short-circuit current. Short circuiting can cause sparks and burns. This voltage can damage measurement equipment
if it is not protected at its inputs. External voltage supplied to this connector will be "diode added" to UHP power
voltage. Supplying negative voltage to center pin more than 24 V of positive voltage is prohibited.

3. State analysis
There are several sources giving information about UHP status and problems.
3.1 Front panel indication
UHP has six LED (Light Emitting Diode) indicators on the front panel. These indicators show status information and
information flow through interfaces.
ERROR
"ERROR" red 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 MCPC channel from the Hub or other UHP. 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 station.
3 - Router cannot calculate time shift with respect to the HUB. The reason can be in the non-availability of reception or a
large number of CRC errors during reception.
4 - HUB cannot receive signal from this station. Please check transmit signal level of the terminal, whether power supply
and the reference signal for the transmitter are switched on (or off if required), whether DTTS or geographical coordinates
are set correctly in the TDMA settings.
5 - Unit is in Backup state of Redundancy mode. Not an error.
Continuous signal with short dims means that the router has hardware or configuration errors, which can be viewed with
the command # show errors .
If ERROR indicator is continuously lit upon power on it means hardware failure of UHP occured which prevents software
from starting. Try to power it off and power on again or press RESET button on rear panel.
STATUS
"STATUS" green indicator indicates the router operation mode. This indicator is always flashing. If it does not flash it
means that the router is not running properly (try to power off or reset). 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 "STATUS" 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).
LOCK
"LOCK" green indicator indicates whether the router receives a channel from the HUB. If there are CRC errors during
reception of information from the channel (e.g. with weak signal from the antenna), the indicator extinguishes for a fraction
of a second at every error. If there are too many errors the indicator may not glow at all in spite of the fact that the router
receives the channel (in this case please check the router demodulator statistics).
TDMA
"TDMA" yellow indicator flashes every time a data placket is received via TDMA RX interface.
SCPC
"SCPC" yellow indicator flashes every time a data placket is received via SCPC RX interface.
TX
"TX" yellow indicator flashes every time a data placket is transmitted in the MCPC mode, and also a burst in the TDMA
mode (bursts can be transmitted even if no data is transmitted inside them).
3.2 Faults
In the router software, there is an information block, which indicates any configuration errors. SYS event in HTTP interface
and "ERROR!!!" message in console prompt appears if the router has any configuration errors:
There are three types of messages:
- Hardware errors.
- Errors associated with the wrong choice of software or router mode.
- Configuration errors.
Current errors can be displayed by clicking on link inside SYS event in using UHP telnet command # show errors .
UHP Software 3.0 User Manual 10
Document version 1.0, May 2013 10

Hardware errors inform about hardware problems with the router. Probably repair is needed.
Software or Mode of Operation errors indicate any mismatch between hardware, software and activated feature licenses.
Configuration error messages focus user's attention on the most important points in the router configuration, that may lead
to instability of operation.
3.3 Events
Events indicate critical conditions of UHP operation. Inducators are red if events are occurring now or yellow if events
occurred before but now their state recovered. Icons remain yellow intil they are cleared with "Clear" link or until UHP is
rebooted. Fault state of stations is transmitted to the hub and then to NMS (if any).

4. UHP access for configuration
4.1 USB interface
When router is connected to a computer via a USB cable the computer creates a serial COM port. The port number can
be found in the Device Manager. To access the port use can be made of either the OS-integrated terminal (Hyperterminal)
or third-party terminal programs.
With the fist connection of UHP-1000 Router to PC the system will request the device driver. UHP.INF driver is available
on CD with documentation or can be downloaded from our web site. In response to the request for driver you should refuse
from search in Internet and select setting from the specified place where UHP.INF is saved.
The system will request confirmation for using a non-certified driver. Ignore any system warnings and proceed with
installation. When finished, please check whether a COM port appeared in the Device Manager. If it is appeared you can
start working with the router.
When working with the port from the terminal program the data rate and control parameters can be set to any value since
they are ignored.
Note: With Windows usb protocol stack there is a peculiarity which leads to "hanging" of the usb-port if it carried an
active session and the connected device (router) at this moment was rebooted. in this case you have to log out from
the terminal program and log in again. you can avoid this by cutting off the session by "hang-up" command and only
then restart the router using reset button or via power supply circuit.
4.2 Telnet interface
Remote access to the configuration can be performed using Telnet protocol. The connection can be provided to any of IP
addresses that are set on the router. UHP-1000 supports simultaneously only one Telnet session. In order the hang
session does not block access to the device forever in case on non-activity (pressing ENTER key), the router auto-
terminates the session after a certain time of inactivity. The time can be set in the configuration, and by default it is 10
minutes.
4.3 Default configuration
By default, UHP-1000 router is configured with IP-address 192.168.222.222 with mask 255.255.255.248 (/29).
Respectively, the computer should be configured with an address, e.g. 192.168.222.217 with the same mask.
Reset to default configuration can be made iither with command # config load default or with special reset button press
sequence. Reset button should be pressed 4 times with ~2 second intervals.
Reset to defaults
Successful reset will be evidenced by fast and simultaneously flashing indicators ERROR and STATUS.
The default address is not shown in the route Table. And what is more, it disappears after the first saving of the
configuration. Thus the first thing to do, with the Telnet access, is to set a new IP-address (it may be equal to the default
address if needed), exit the session, and connect to the new address and only then save the configuration.
After the first saving of the configuration the ERROR and STATUS indicators stop flashing simultaneously.

5. Command interface
UHP has command interface suitable for initial routing setup, monitoring and diagnostics. Command interface works
equally when connecting via USB or Telnet or via local serial console (available in OEM versions of UHP).
Telnet has precedence over USB and serial console. USB has precedence over serial console.
When opening a command session (Telnet of USB) the router can, depending on the configuration, request a password. If
password is not set the commands can be entered immediately.
The system invitation starts with the router name (it is set using the relative command). Then enter "#" symbol in the
administrator mode or ">" symbol in the user mode (user cannot change configuration).
Router commands include key words and parameters. All key words can be reduced to two letters. Letter case is
unimportant. Wrong entered symbols can be edited by returning to them using Backspace key. "Left" and "right" arrows
cannot be used for editing. "Up" arrow is used to recall commands used earlier.
Command syntax meaning
[ ] - optional parameter
x|y - selection of one of the key words, e.g. "on" or "off"
x-y - numerical value in the range from x to y inclusive
STRING - symbols string
IP_ADDR - IP address, e.g. 192.168.0.1
IP_MASK - IP mask in classical or CIDR form (255.255.255.0 /24 /32)
Note: IP address and mask must be separated by blank space - these are different parameters.
Full list of commands
Commands list can be displayed using # help . Most of commands have equal items in HTTP interface. Commands
which do the things unavailable in HTTP or have additional modes are shown in bold.

6.4 Main screen overview
Overview screen shows thorough real time statistics of software modules. It is automatically refreshed every 30 seconds.
In case of loosing a link to UHP browser can display error instead of information here. In this case user should refresh the
page with browser "Refresh" button of F5 key. Some items of overview are links to appropriate settings or stats.
Screen consists of several sections. First three sections are always there, other section presence depends on current
profile mode and activation of certain services. All information from sections is also available in extended statistics
screens which can be opened from tree or from direct links in sections.
UHP overall information section
Overview section
Interface statistics section
Interface statistics
Main operation information, traffic and errors for each interface are shown. Counters can be cleared in clear counters
screen. For LAN interface link state is shown, for demodulator search information or reception quality, for modulator TX
level and TLC state. For Network interface number of RX errors is a sum of all errors of all stations plus errors of TDMA
protocol itself.
Network statistics section
This section appears only if current profile is hub profile. Section is divided into three colums showing statistics of stations,
bandwidth allocation and TDMA protocol.

7. Site setup
Site setup
Site setup screen allows to configure UHP parameters related to installation site.
First unit name is configured. This name appears in top frame and in Telnet command prompt.
Location
Site georgaphical location is specified. Location is used in TDMA timing calculations for stations and neseserity of
location setup depends on timing mode selected. By default location is required for proper TDMA station installation.
RF interface
Here parameters needed for proper functioning of antenna RF equipment are set. Compensations for RF equipment or
satellite frequency shifts are also set here. Compensations of frequencies are needed to adjust actual RX and TX
frequency values to adjust values supplied by hub.
Local oscillator of LNB. Obtained from datasheet. Typical values are 10000000 or 9750000 kHz.
This value is usuallly subtracted (if spectral iversion is off) from all RX frequencies set in profiles
or received from hub within return channel configuration to produce final L-band вњ– value of RX
frequency set on demodulator 950000-2150000. If value is zero (by default) all frequencies should
be set in L-band.
Receive LO
Critical: LO frequencies should either be properly set on WHOLE network or left zeroes on
WHOLE network. Mismatch can result in completely wrong final frequency calculations,
system faults, no service, carrier interference.
Local oscillator of BUC transmitter obtained from datasheet. Typical values 13050000 or
12800000 kHz. This value is subtracted from all TX frequencies set in profiles or received from
hub within return channel configuration to produce final L-band вњ– value of TX frequency set on
modulator 950000-1750000. If value is zero (by default) all frequencies should be set in L-band.
The same warning as in receive LO applies.
Transmit LO
Turns on LNB power 18V on demodulator or 24V power for BUC on modulator, see current
limitations in specification.
