1. Introduction
The Nera SatLink 1000, 1900, 1901 and 1910 are members of the Nera SatLink Terminal family of DVB-
RCS Terminals. They act as IP routers to interface one or more PCs for bilateral communication via the
satellite network. This User Guide covers the installation and operation of the Nera SatLink
1000/1900/1901/1901, commonly also referred to as the indoor unit (IDU) of the DVB-RCS terminal,
together with the accompanying outdoor unit (ODU) equipment.
The parameters of equipment transmitting to satellites are regulated by national and international
authorities in several countries in the world and by the satellite operators themselves. The standards now
in force are described in references [7], [8], [9] and [10]. The SatLabs group, of which Nera Broadband
Satellite is a member, now works to establish type approval for DVB-RCS terminals in cooperation with
Cetecom. Nera will certify its DVB-RCS terminals by these type approval guidelines as soon as they have
been finalised.

1.2 Configuration tool overview
The Nera SatLink Terminal must be configured before it can communicate via the satellite to and from
the network operator Gateway. The parameters to be configured are explained in section 6.2.
The configuration of the terminal can be carried out using the configuration tools:
•Command Line Interface
-Via RS232/Terminal emulator (e.g. HyperTerminal)
-Telnet
•Web-interface
•SNMP
Configuration via CLI and Web-interface is presented in this document. For terminal management via
SNMP, the reader is referred to [6].

3. Installation
3.1 Before installation
3.1.1 Safety
Follow these guidelines to ensure general safety:
•Always comply with national and local electrical codes.
•Keep the installation area clear and dust free during and after installation.
•Keep tools and all components away from walk areas.
•Do not wear loose clothing, jewellery (including rings and chains), or other items that might get
caught on the IDU, the ODU or the interconnecting cables.
•Do not work on the system or connect or disconnect cables during lightning storms.
Follow these guidelines when working with electrical equipment:
•Disconnect all power and external cables before installing or removing a SatLink Terminal.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not act in any way that creates a potential hazard to people or makes the equipment unsafe.
•Never install equipment that appears damaged.
•Carefully examine your work area for possible hazards such as moist floors, unearthed mains
extension cables and missing protective earths.
Should an electrical accident occur:
•Be cautious – do not become a victim yourself.
•Turn off electrical power to the system.
•If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and
then call for help.
•Determine if the victim needs artificial respiration or external cardiac compressions; then take
appropriate action.
3.1.2 Site requirements
The Nera SatLink Terminal shall be connected to the mains 110/230 VAC, 50-60Hz.
