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 pressure 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 “nppppf”
‘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) 4
