GENERAL DESCRIPTION AND INSTALLATION GUIDE, v3.2

1. GENERAL DESCRIPTION

1.1 System overview

UHP satellite routers are essentially a universal solution for geographically distributed VSAT-class satellite

communication networks. UHP routers can be used to organize simple point-to-point channels, “star”- and

“mesh”-topology networks with several hierarchy levels and bandwidth-on-demand capabilities.

UHP VSAT platform is based on many innovation technologies. It was developed using long-term experience in

satellite service provisioning. Nowadays electronics achievements made it possible to make VSAT platform

compact and assure its efficiency and reach functionality.

Figure 2 UHP-100 Satellite Router

Technical characteristics are given in the appropriate product specification sheets.

1.2 Measurement equipment, tools and accessories

Standard computer (notebook) is required to configure and monitor status of UHP-100 satellite router. The

computer must be equipped with a LAN interface and USB, and also have the following software installed:

Internet browser (WEB browser)

Telnet Client

The Terminal (e.g.: Hyperterminal, included in the OS Windows) (optional)

The router can be accessed via LAN or USB ports. Standard USB AM/BM cable (not supplied) is required for

connection to USB “Console” port of the satellite router.

Connection of a computer to the router via LAN interface is implemented through the Ethernet switch or hub via a

standard network cable with RJ-45 connectors (not supplied).

1.3 Labeling and sealing

The product is marked with the unique Serial Number, as well as Part Number on the bottom of the router case.

The warranty seals are located on the bottom of the product, at the junction of the two parts of the case. Product

warranty will automatically void if such labels have been removed, modified or damaged.

GENERAL DESCRIPTION AND INSTALLATION GUIDE, v3.2

1.5.1 Overview

Each module of UHP-100 satellite router has its own interface to external devices. All the interfaces are

located on the rear panel of the device. The indicators are located on the front panel. LAN Indicators are

integrated into the LAN connectors on the back of the router.

1.5.2 Router composition

UHP-100 router consists of:

1. IF switch with two inputs

2. Two high-speed DVB demodulator

3. Universal modulator

4. IP Router

5. Ethernet switch with two Fast Ethernet interfaces

6. USB console

7. Power supply

Figure 5 UHP-100 router –rear view

1.5.3 Power connector (DC 24V)

UHP-100 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 central contact.

1.5.4 LAN interface connectors (LAN1 and LAN2)

LAN connectors are purposed for connecting of the CPE or for cascading of several routers. Bit rate 10 or 100 Mbps

are supported. Indicators built into the connector mean the following: green –connection (Link) and data

transmission (Activity), yellow –activation of half-duplex mode.

1.5.5 USB CONSOLE

The console port provides local control of the device. A standard miniUSB cable is required to connect to the

router (not supplied).

1.5.6 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 VIS

PROHIBITED.

UHP-100 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.

UHP-100 HIGH-THROUGHPUT SATELLITE ROUTER

GENERAL DESCRIPTION AND INSTALLATION GUIDE, v3.2

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

transmitter and 10 MHz reference signal. UHP-100 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.

ANY OPERATIONS WITH IF TX CABLE SHOULD BE PERFORMED WITH 24 VSUPPLY VOLTAGE TURNED OFF.OTHERWISE,

SELF-INDUCTION ACROSS A LONG CABLE CAN DAMAGE THE TRANSMITTER AND/OR ROUTER.

1.5.7 RESET button

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

reset to factory settings.

1.5.8 IF switch inputs (RX1 and RX2)

UHP-100 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.

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.

Figure 6 Satellite Router UHP-100 series - front view

1.5.9 “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).

1.5.10 “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.
