to congure the DAT-Link + for input and output to the ProPort at 48,000
samples/second. If a dierent sampling rate is required, use the appropriate
entry from Table 11.1 instead of Pro48 . The last setting in Table 11.1 indicates
that the ProPort should use the DAT-Link +'s digital audio output clo ckto
derive the sampling rate.
5. Load the DAT-Link +'s DSP32C with the ProPort I/O program:
naloaddsp PRO16
Note that the \16" sux applies only for DAT-Link revision 1.6. For DAT-
Link revision 1.5 use PRO15 instead.
6. Playback and/or record les via the ProPort using the naplay and narecord
programs. The programs will function as described in Sections 5 and 6 with
the following exceptions:
 Sample-rate conversion ( -s option) is not available. All input and output
will b e at the rate set for the ProPort as indicated in Table 11.1.
 The -S option will have no eect.
 Only linear encoding with 16 bits/sample will be available.
7. To switch back to using the DAT-Link +'s digital inputs and outputs for play-
back and recording, type:
naloaddsp
naset -c
