1. Introduction

The STM SatLink 1000, 1900, 1901 and 1910 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 mains circuits are properly earthed and use the mains cord supplied with the

SatLink VSAT IDU to connect it to the mains outlet.

•If your installation requires a different mains 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 mains outlet into which it is plugged can be reached so it may be unplugged if need be.

•Ensure that the unit does not overload the mains 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 ampere ratings are usually printed on units near their mains

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 needs 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.

Publication no. 101557, Rev. U, August 9th, 2007 Page 13

Figure 9: Rack Mounting

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 13 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.

Do not connect the Tx cable before the initial configuration of the STM SatLink VSAT

IDU is performed to ensure that incorrect or hazardous signals are not sent to the satellite

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, STM article no 106208

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.

Publication no. 101557, Rev. U, August 9th, 2007 Page 14

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.

For the STM SatLink 1900 and 1901, toggle the back panel push button to set Ethernet HUB or NODE

mode. Toggle to NODE when connecting to an Ethernet switch or an Ethernet hub and toggle to HUB

when connecting to a single PC.

For the STM SatLink 1000 and 1910 there is no push button on the back panel as Ethernet HUB or

NODE mode will be auto-detected and the correct mode chosen automatically.

3.5.3 Mains connection

The STM SatLink 1900/1901/1910 models have internal power supply and consequently are connected

directly to a 110/230 VAC 50/60Hz outlet using a standard 230 VAC mains cord.

3.5.4 Power supply

The STM SatLink 1000 has an external power supply that is connected to a 110/230 VAC 50/60Hz outlet

using a standard mains cord.

The STM SatLink 1000 must only be connected to the external power supply that is

approved by STM , PN 104170 (LEI-S2425D / 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 3is 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.

Publication no. 101557, Rev. U, August 9th, 2007 Page 16

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 Window 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, Rev. U, August 9th, 2007 Page 17

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 (see section

6.2.1). The IP configuration parameters to use for PCs connected to the VSAT LAN are supplied from the

system operator or service provider. Please 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.

Publication no. 101557, Rev. U, August 9th, 2007 Page 18

5. Using the Command Line Interface of the SatLink VSAT

The command line interface can be accessed via either Telnet or the RS-232 port for management of the

SatLink VSAT IDU as well as for showing status and reports.

5.1 CLI users access rights

Four levels of CLI user access rights are available for differentiating user privileges:

•Level 2: installer

•Level 3-5: end users

When shipped from the factory, one user is pre-configured in the SatLink VSAT:

User name Factory default password Privilege level

Install dvbrcs 2

When accessing the CLI via RS-232, if the login prompt is not displayed type ENTER. The login prompt

Password: dvbrcs

When the command prompt is displayed you will now have access to the CLI with privilege level 2.

New users may be added with the CLI command user add, existing users deleted with the CLI

command user del, and the password of the current user or users with lower privilege levels can be

changed with the CLI command user passwd. To list all defined users with lower privilege level than

the user currently logged in, use the CLI command user show. Type ? user to get further help on the

user commands.

For security reasons we recommend that you change the factory set password to your own personal one.

5.2 Online help
