The ' f ' parameter identifies the format of each selected acquired datum in each data group of
the stream scan, and is a single numeric digit. Valid format codes are listed in the following
table:
f
converts each internal response datum value from:
0
single binary float
1
single binary float
2
double binary float to 16-digit hex integer " xxxxxxxxxxxxxxxx"
5
single binary float
integer
7
single binary float
8
single binary float
Note
The number of stream scans ( 'num' ) parameter is a positive integer count (from 0 to
2147483647, specified with 1 to 10 numeric digits as needed). It sets a finite limit on the
number of scans delivered in the host data stream. The value 0 for this parameter requests
"continuous" (i.e., unbounded) output scans of the defined host stream.
Example 1:
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 (without bound) and synchronized
with the internal clock at 100 msec., 200 msec., and 400 msec. periods, respectively. Data are
requested in single precision binary big-endian IEEE float format ( f =7). This is the module's
most efficient "native" format.
"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:

to 7-10-digit signed decimal " [-xxx]x.xxxxxx"
to 8-digit hex integer " xxxxxxxx"
to
long integer (EU*1000) then to 8-digit hex
to single binary float (big endian: msb first)
to single binary float (little endian: lsb first)
With the exception of binary formats 7 and 8, all other formats
include at least one leading space in each datum delivered in each
stream scan.
