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
“n[p]ppppf”
‘n’ is the command letter
‘[p]pppp’ is the position field
‘f’ is the format field
Response
“ dddd[ dddd]...”
‘ dddd’ are datum fields, each with a leading space (except f =7).
Description: The 4 or 5 character hex position field ([p]pppp) specifies a 16 or 20 bit binary bit-
map, with each bit set to 1 to specify a particular channel number (S & P external
rack channels, plus internal channels 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. 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.

single binary float
to
7-10-digit signed decimal “ [-xxx]x.xxxxxx”
