DVB-S2 Rexeption

Submitted by themetman on Tue, 04/09/2019 - 07:12

With Eumetcast starting the new DVB-S2 reception starting in August 2014 and replacing the DVB-S reception in December 2014, I have made some notes on setting up an Ayecka SR1 receiver. There is a utility provided by Eumetsat which runs in Windows to set the configuration for you. However the network settings may not match your setup and you will have to either login to the console to correct that using telnet as below, or use the USB cable. I use the telnet application to get into the console from one of my Linux machines. You can use PuTTY if you are using Windows. So in Linux from a terminal type:

telnet <IP_ADDRESS OF SR1>

Enter the password (default is 'telnet') to get to the main menu

1. Configuration
2. Status
3. Network
4. System
5. Statistics
6. ACM Client

then using the numbers 1, 1, 1 to navigate to the Config RX Channel 1 -> Configuration Set 1 item, you can change the settings to match those below.

Limitations

I would have liked to have been able to setup the RX1 for the DVB-S and RX2 for the DVB-S2 and have two dishes, one for each, but there is a limitation of 8 for the number PIDs you can have in total, so they have to be on the same RX, which means physically changing the cables from the dishes.
