READ TEMPERATURE VOLTAGES (Command ‘n’)
Purpose:
Returns the most recently acquired
raw temperature
data for the specified
channels converted to engineering-unit Volts directly from the averaged A/D
counts. It is similar to command
‘V,’
except that the raw data reflects a channel’s
temperature
signal instead of its
pressur
e signals. Each datum returned in the
response will be in the specified high-precision data format.
This command is
intended for advanced users only and is not required for normal operation.
Command
“
n
ppppf
”
‘
n
’ is the
command
letter
‘
pppp
’ is the
position
field
‘
f
’ is the
format
field
Response
“
dddd.. dddd
”
‘
dddd
’ are the
datum
fields, each with a leading
space
(except
f
= 7
or 8).
Description:
The 4-character hex
position
field (pppp) specifies a 16-bit binary bit-map, with
each bit (set to 1) specifying a particular channel number (16-1, left-to-right).
The
1-character
format
field (
f
) specifies the format of each
datum
field (
dddd
)
that will be returned in the requested response. The first datum returned in the
response will be for the highest channel number supplied, and each (non-binary)
datum will be preceded by a
space
character. Some formats may not be
applicable to the specific type of data being requested. Valid formats are shown
in the following table:
f
converts each internal response
datum
value from . . .
max. char.
0 single binary float
to 7-10-digit signed decimal “ [-xxx]x.xxxxxx”
13
1 single binary float
to 8-digit hex integer “ xxxxxxxx”
9
2 double binary float
to 16-digit hex integer “ xxxxxxxxxxxxxxxx”
17
5 single binary float
to long integer (EU*1000) then to 8-digit hex integer
9
7 single binary float
to single binary float (big endian: msb first)
4
8 single binary float
to single binary float (little endian: lsb first)
