6.3.4. UDP Parameters
The UDP section (figure 5.4) holds all the settings specific to UDP. In UDP mode each acquisition
cycle (of ‘x’ number of channels) is packed as a separate UDP packet with a four-byte representation
of the flightDAQ serial number at the start of the packet. These are attempted to be sent out at the
required rate but with no checking for reception or validity of data.
Note that the flightDAQ’s local IP address and local subnet are the same setting as the TCP Comms,
so changing them here will also change it in the TCP page. Also note that the flightDAQ’s local UDP
port is also fixed at 101. Furthermore, it should be noted that due to an oddity in the protocol firmware,
when switching protocol from UDP back to TCP, the user has to select a data rate as well, to complete
the switch back to TCP.
Settings available from this section include setting the UDP address and port for a remote connection
(for auto streaming via UDP at boot up) and a setting that allows the user to set the data output to
IENA specification format.
