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:

converts each internal response datum value from..

max. char.

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

single binary float to 8-digit hex integer “ xxxxxxxx”

double binary float to 16-digit hex integer “ xxxxxxxxxxxxxxxx”

single binary float to long integer (EU*1000) then to 8-digit hex integer

single binary float to single binary float (big endian: msb first)

single binary float to single binary float (little endian: lsb first)
