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).
Models 9021 and 9022 use only channels 12-1.
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:
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
