NALOOP(8)
–u host:unit
Use the NetAudio server on host that is connected to the DAT-Link with unit-number unit.
Otherwise, use the value of the
then use unit 0 on the local host.
EXAMPLES
To run a loop-back test for 10 seconds at each of the 3 sampling rates using each of the digital
input/outputs, connect a loop-back cable between each input/output and run naloop with no arguments.
T o test only the RCA input/output for 1 minute at each sampling rate, use:
example% naloop -i RCA -t 60
e xample%
To test the Fiber-optic input/output at 44,100 samples/second, running until interrupted, use:
example% naloop -i fiber -s 44100 -t 0

DIAGNOSTICS
naloop exits with status of 0 if everything was fine. If there was a command line error, exit status 1 is
returned. Communication errors with the DAT-Link result in an exit status of 2. If there were data
e rrors (mismatch between actual and expected data), an exit status which is the negative of the number
of failing conditions (sampling rate and input source). Error messages are also displayed.
E NVIRONMENT
Default NetAudio server to use, of the form host:nn , where host is the name of the
AUDIO_DEVICE
host where the server is running and nn is the unit number of the DAT-Link to use
