READ TEMPERATURE COUNTS (Command ‘m’)
 
 
Purpose:   Returns the most recently acquired raw temperature data for the specified  
 
 
  channels in averaged A/D counts (in the range -32768 to +32767).  This  
 
 
  command is similar to command ‘a,’ except that the raw data reflects a channel’s  
 
 
  temperature signal instead of its pressure signal.  Each datum returned in the  
 
 
  response will be in the specified high-precision data format, but representing A/D  
 
 
  counts as a signed integer  average.  This command is intended for advanced  
 
 
  users only and is not required for normal operation
 
 
 
Command 
mppppf” 
 
‘m’  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 data 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: 
 
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” 
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 
7  single binary float 
to  single binary float (big endian: msb first) 
8  single binary float 
to  single binary float (little endian: lsb first)
