NOTE: The type of data delivered for each specified channel (when the streams
are started) is EU pressure unless sub-command “05” is also executed to
select other types of data in each stream.
Example:
! Configure three (3) separate autonomous host delivery streams, and divide the
module’s channels between them. Channels (1-4) must be delivered to host as fast
as possible, channels 5-8 may be delivered at half that rate, while the remaining
channels 9-16 are delivered at half the previous rate. All streams are generated
continuously and synchronized with the internal clock at 100 msec., 200 msec., and
400 msec. periods, respectively. Data are requested in single precision binary IEEE
float format f=7).

c 00 2 00F0 1 200 7 0"
c 00 3 FF00 1 400 7 0"
Read response:

To similarly acquire data at “relative” rates (1, 2, and 4) using a periodic hardware
trigger (assumed to also cycle at 10 Hz rate), enter the commands:
c 00 1 000F 0 1 7 0
c 00 2 00F0 0 2 7 0
c 00 3 FF00 0 4 7 0
Read responses:

The above example is for a Model 9016 module. It would also be suitable for a
Models 9021 and 9022 if no channels above 12 are scanned as in stream 3 above.
