RUNNING A SPEEDTEST
The only true way of testing the speed of the satellite link is to send a UDP (non-hand-shaking)
stream across it but even this is not 100% accurate as it depends on an IP connection (usually
internet) between the iDirect (receiving) hub and the decoding device. A speed test can be
achieved through streaming video from an encoder to a decoder or by using a program called
iperf.
Before streaming can take place you need to:
a)
Download iperf onto the ‘transmit’ and ‘receive’ computers
b)
Ensure the ‘receive’ computer has a cabled connection to the router (NOT WiFi)
c)
Discover the IP address of the ‘receive’ computer
d)
Map the IP address of the ‘receive’ computer to the TX port number (specified in the
TX computer iperf address) - this tells the home router to forward any incoming data
(arriving at the destination IP address) to the receive computer
e)
Discover the public IP address of the destination (held in the home router)
a)
Downloading iperf:
You can download iperf from https://iperf.fr/download/iperf_2.0.5/iperf-2.0.5-2-win32.zip
Please note that iperf does not currently run on Windows 8
c) Discover the IP address of the ‘receive’ computer
Ensure the computer has a cabled connection to the home router (NOT WiFi)
From the Control Panel, open the
Network and Sharing Centre
