1. Introduction
The STM SatLink 1000, 1910, and 2000 are the indoor units (IDUs) of the STM SatLink VSAT family of
DVB-RCS VSATs. They perform several functions: they are satellite modems (at Layer 1); they handle
data link layer processing (at Layer 2) for both satellite and LAN communications; and they act as IP
routers and DHCP servers (at Layer 3). All SatLink IDUs provide an Ethernet 10/100 LAN interface for
one or more PCs to engage in two-way communication via a SatLink (or any DVB-RCS compliant)
satellite network.

3.3 IDU Installation
3.3.1 On Desktop or Shelf
Place the STM SatLink VSAT IDU on a flat, stable surface, such as a desktop or shelf, close to the PC or
network device to which it will be connected. Keep its top, bottom and all sides unobstructed to ensure
free airflow. Rubber feet on the bottom provide adequate clearance. Ensure that there is at least 10 cm
clearance at the back to allow room for cable connections.
3.3.2 In Rack
The rack or cabinet should be properly secured to prevent tipping. Equipment that is
installed in a rack or cabinet should be mounted as low as possible, with the heaviest units
lower down, and lighter units toward the top.
Precautions:
•Ensure that the power circuits are properly grounded and use the power cord supplied with the
SatLink VSAT IDU to connect it to the power outlet.
•If your installation requires a different power cord than the one supplied, ensure that the cord used is
certified as indicated by the stamped or embossed logo of the electrical safety authority in your
country.
•If the on/off switch on the back panel is difficult to reach when the unit is fitted in the rack, ensure
that the power outlet into which it is plugged can be reached so it may be unplugged if necessary.
•Ensure that the unit does not overload the power circuit, wiring or over-current protection. To
determine the possibility of overloading the supply circuits, add together the ampere ratings of all
devices installed on the same circuit as the STM SatLink VSAT IDU and compare the total with the
rating limit for the circuit. The maximum amperage ratings are usually printed on units near their
power connectors.
•Do not install the STM SatLink VSAT IDU in a location where the operating ambient temperature
may exceed 45°C.
•Ensure that the airflow around the sides and back of the SatLink VSAT IDU is not restricted.
The STM SatLink 1900/1901/1910 can be mounted in any EIA-standard 19-inch telecommunications
rack or cabinet. The STM SatLink 1000 and 2000 need to be placed on a shelf if it is to be placed in a
rack.
Use a Torx screwdriver and attach the mounting brackets to the router with the screws supplied. Hold the
unit securely, brackets attached, and move it vertically until rack holes line up with the bracket notches,
then insert and tighten the four screws holding the brackets to the rack.
Figure 9: Rack Mounting
SatLink VSAT User Guide
Publication no. 101557 Copyright © 2009 – STM Group, Inc. Page 13 (160)
3.4 ODU Installation
Install the ODU as described in Appendix F, reference [1], and the antenna installation manual. When
installing the STM SatLink 403x transceiver, please check Table 9 in Appendix G whether an adapter is
required to interface the antenna feed horn.
3.5 Interface Connections
3.5.1 RX/TX cables between IDU and ODU
The coaxial cables from the ODU are connected to the type F coaxial jacks on the back panel of the STM
SatLink VSAT IDU.
•Connect one coaxial cable from the ODU TX module input to the jack marked TX.
•Connect one coaxial cable from the LNB to the port marked RX on the back panel.
Use only 75 Ωcoaxial cables fitted with type F plugs for the RX and TX cables. Make sure
that the connectors are of a waterproof version such as F-connector RG6 Compression type
from Cablecon (www.cablecon.dk), article no 99909446
Do not connect and disconnect the coaxial cables with power connected to the STM
SatLink VSAT IDU.
Hint
Use different colour marking on the TX and RX coaxial cables to eliminate likelihood of
interchanging the RX and TX coaxial cables.
3.5.2 Ethernet connection to a Local Area Network (LAN)
The STM SatLink VSAT IDU may be connected to a single PC or to a network via the RJ-45 Ethernet
jack on the back panel.
•Plug one end of the Ethernet cable into the RJ-45 jack on the back panel.
•Plug the other end of the Ethernet cable into the RJ-45 jack a Local Area Network (LAN) device such
as an Ethernet hub, switch or router, according to its manufacturer’s instructions.
The STM SatLink will auto-detect if Ethernet HUB or NODE mode is used and will automatically chose
correct mode, hence there is no need to use a cross-over Ethernet cable for direct connections to PCs.
3.5.3 Power connection
The STM SatLink 1910 models have internal power supply and consequently are connected directly to a
110/230 VAC 50/60Hz outlet using a standard 230 VAC power cord.
3.5.4 Power supply
The STM SatLink 1000 and 2000 have an external power supply that is connected to a 110/240 VAC
50/60Hz outlet using a standard power cord.
The STM SatLink 100 and 2000 must only be connected to the external power supply that
is approved by STM, PN 104170 (LEI-S2425D/Adapter Technology, Model No. STD-2425).
Use of another power supply will void warranty.

4. Connecting a PC to the SatLink VSAT
After installation as described in Chapter 3 is carried out, the VSAT IDU is ready to be powered on.
4.1 Windows TCP/IP Configuration
Verify that the TCP/IP configuration is correct for PCs connected to the LAN you plan to use for your
SatLink VSAT. Push the start-button in Windows, select the Control Panel and then open Network
Connections. Right-click on the relevant Local Area Connection and select Properties. A new window
showing the Network Connection Properties will pop up. In the General submenu of this window, scroll
down, select Internet Protocol (TCP/IP) and then push the Properties button shown in Figure 10. Then
configure the PC client to obtain the IP address automatically from the VSAT IDU (section 4.1.1) or
configure the PC with a static IP address (section 4.1.2).
Figure 10: Windows XP Menu for Configuring the Client TCP/IP Configuration.
SatLink VSAT User Guide
Publication no. 101557 Copyright © 2009 – STM Group, Inc. Page 15 (160)
4.1.1 Dynamic IP configuration of PCs connected to the VSAT LAN
By default the DHCP server in the SatLink VSAT is enabled. When the SatLink VSAT is powered on, all
PCs connected to the VSAT LAN can automatically retrieve their IP configuration from the DHCP
server. The user should verify that the Windows clients are configured to obtain an IP address and DNS
server address automatically. Figure 11 shows the correct Windows XP configuration when the DHCP
server is enabled in the VSAT.
Figure 11: Windows XP TCP/IP setting when DHCP server is enabled in the VSAT
From an MS-DOS window, the user may type ipconfig /all command to verify that the computer has
received correct configuration parameters from the DHCP server such as IP address, subnet mask, default
Gateway, DNS servers and lease time.
Figure 12: ipconfig /all print out from an MS-DOS window

Publication no. 101557 Copyright © 2009 – STM Group, Inc. Page 16 (160)
4.1.2 Static IP configuration of PCs connected to the VSAT LAN
When the DHCP server in the SatLink VSAT is disabled, all PCs attached to the VSAT LAN must be
configured with static IP addresses that are within the address range of the VSAT subnet. The IP
configuration parameters to use for PCs connected to the VSAT LAN are supplied from the system
operator or service provider. Configure the IP address, Subnet mask, Default gateway, Preferred DNS
server, and optionally the Alternate DNS server as shown in Figure 13.
Ensure that the actual IP addresses supplied by the system operator/service provider are
configured and not the IP addresses in the example figure.
Figure 13: Windows XP TCP/IP setting when DHCP server is disabled in the VSAT
Example:
A host may have the following configuration; IP address 192.168.0.2, Subnet mask 255.255.255.0 and
default gateway 192.168.0.1, where the IP address of the default gateway should be the IP address of the
VSAT LAN interface.

The SatLink VSAT Web interface is used to configure a number of parameters before the VSAT can
acquire the forward link and communicate with the Hub via the satellite connection. A default
configuration specifying most of these parameters is pre-loaded on each STM SatLink VSAT, either in
the factory or by the service provider before installation. The following configuration parameters are
typically to be configured using the VSAT Web interface:
-DVB-S2 Reception parameters
-VSAT GPS Position
Other parameters are typically configured automatically from the Hub when the VSAT logs on for the
first time . When other ODUs than the SatLink 403x transceiver is used or if e.g. the Hub operator does

not use automatic VSAT configuration then additional VSAT parameters ight have to be configured
during installation.
6.2.1 Receiver Parameter Configuration
The STM SatLink VSAT is normally pre-configured to be used together with the STM SatLink 403x
transreceiver. But, it is possible to configure the STM SatLink VSAT to operate together with other
transreceivers than SatLink 403x. The list of LNBs that can be used with the STM SatLink VSAT are
listed in Table 5

2) Configure the Receiver parameters as shown in the following table.
Parameter Description
Auto Start •ON
•Off
Specific for the receiver. When set to "ON" the VSAT will automatically acquire the
forward link. It is recommended to always set this to ON for normal operation. Please
always restart the VSAT after saving configuration when having set auto start to ON.
LNB Type Specifies the LNB type with which the VSAT is configured.
Index Table index [0 – 9]. The SatLink VSAT can store up to 10 forward link entries and the
table index is used to identify a single entry.
Priority Forward link search order [0 – 1]. Search is started for priority 0 first and ends with
priority 1.
Symbol Rate (Msps) The forward link symbol rate in Msps.
Frequency (Ghz) Forward link frequency [kHz].
Mode Enter the valid modes :
•DVB-S
•DVB-S2
PopId Population ID to use for forward link acquisition. The STM SatLink VSAT will select
which group in the DVB-RCS system it belongs to based on the configured population
