Data Output Formats
During or after the acquisition, issuing the Set Data Format (
F
) command determines the format of
output data coming from the TempScan/1100 or MultiScan/1200 unit. However, data output formats
differ slightly from data input formats in that Binary formats may be used, and used only for the output
of channel data.
Channel data , defined as data originating from the High/Low/Last (HLL) Registers or
the Acquisition Buffer, may also be output in the Engineering Units or ASCII Count format as well as
the Binary format.
The commands which can initiate channel data output (in Engineering Units, Binary, or ASCII Counts
format) are the
Read Buffered Data (
R
), Read Last Readings (
R#
), and following User Status (
U
)
command queries: Query current HLL Registers (
U4
), Query and clear current HLL Registers (
U5
) and
Query last scan read (
U13
). Meanwhile, the three commands queries which can initiate output in
ASCII Count format are the following: Query current channel configuration (
C?
), Query the current
trigger level settings (
L?
), and Query configured channels (
U8
).
Note: (1) Channel data is the only output data which may use the Binary format. If the Binary
format is selected, then the Engineering Units
engr
parameter will be ignored. (2) For all
other types of output data, if an Engineering Units or Binary format is selected as the data
output format, then these output data values will be interpreted as Engineering Units. (3) If
the ASCII Count format is selected as the data output format, then the output data values will
be interpreted as Count, and the Engineering Units
engr
parameter will be ignored.
Example 12l. Data Output Format Cases
PRINT#1,"OUTPUT07; F0,0X"
•
Case 1: This command line interprets the output data as Engineering Units, Degrees C for the next
R
,
R#
,
U4
,
U5
, or
U13
command issued, and also for the next
C?
,
L?
, or
U8
command issued.
PRINT#1,"OUTPUT07; F1,1X"
•
Case 2: This command line interprets the output data as Binary for the next
R
,
R#
,
U4
,
U5
, or
U13
command issued (only channel data can be in Binary format), but also interprets the output data as
Engineering Units, Degrees F for the next
C?
,
L?
, or
U8
command issued.
PRINT#1,"OUTPUT07; F3,3X"
•
Case 3: This command line interprets the output data as ASCII Counts for the
R
,
R#
,
U4
,
U5
, or
U13
command issued, and also for the next
C?
,
L?
, or
U8
command issued. In this case, the
Engineering Units
engr
parameter is ignored.
