1 Gbps LAN card
 

Edimax LAN-to-USB also useful     

This data is taken from PCs fed by two Ayecka SR1 IP receivers.  The RF feeds are shown in red.  The antenna is pointed to the EUTELSAT 10A satellite at 10° E.  Readings are taken every five minutes, and X-axis times are in UTC.  

Receive PCs are fed from the Traffic LAN ports of the Ayecka SR 1 IP receivers on two private LANs (192.168.10.x/20.x) via GS605 Netgear switches, with 1 Gbps network cards shown as # added to the receiver PCs.  An Edimax USB2.0-Ethernet adapter is an alternative because of better drivers.  From Jan 2015, PC Stamsund has been fed from a TBS5925 USB box.  From Feb 2016, SR1 #2 receiver takes only HVS received on PC Kiruna, and receive-only on PC Lund.  From Feb-2017 PC Lund monitors HVS-1 & HVS-2 with a single-input TBS6903 dual-tuner PCIe card.

The Ayecka SR1 Management ports are connected to the existing 192.168.0.x house LAN, through which management access is possible from any local PC.
