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.
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
