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 Ω coaxial 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.
