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 1 000F 1 100 7 0”

“c 00 2 00F0 1 200 7 0"

“c 00 3 FF00 1 400 7 0"

Read response:

“A”

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:

“A”

The above example is for a Model 9016 module. It would also be suitable for

Models 9021 and 9022 if no channels above 12 are scanned as in stream 3 above.

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.
