Pressure Systems, Inc. Model 9116 User’s Manual

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:

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
