The /m and /z parameters provide simply-formatted versions of output from the read program that are
convenient for further processing with your own programs.
It is possible to redirect the output of the read program to a file using its /o parameter. In this case, any event
/ error waveforms in the input file are stored to separate waveform files and the report file is annotated with the
waveform filenames. It is not advisable to use the operating system’s redirection mechanism (’>’), because any
waveforms in the input file will be drawn to the screen without a convenient mechanism to match them to a
position in the redirected output file.
9.3.1. Example Output from the read Program
The following brief output from the read program shows the content of a number of 4-byte SpaceWire packets,
together with time-tags of the first byte in each packet and the corresponding end-of-packet token. The data rate
reported, 40.0 Mbits/sec, is the user data rate; this will have been transmitted across SpaceWire at 50.0
Mbits/sec with 2 bits of protocol overhead per byte [the parity bit and the data / control flag].
9.3.2. Plug-ins for the read Program
The usual function of a plug-in is to examine a received packet and, if it is recognised, to interpret it for display.
A plug-in file is provided for the read program to provide interpretation of the SpaceWire RMAP protocol:
ProtocolRxRMAP.class
This plug-in may be invoked using the /p parameter to the read program:
java -jar read.jar <filename> /p RMAP
