READ TRANSDUCER VOLTAGES (Command 'V')

Purpose: Returns, for the specified channels, the most recently acquired raw pressure data, converted to volts directly from the averaged A/D counts. This simple engineering-unit conversion bypasses any usage of the transducer’s factory- calculated coefficients or the final calibration process’s correction coefficients (offset and gain). 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	“V[p]ppppf”
Command
	‘V’ is the command letter
	‘[p]pppp’ is the position field
	‘f’ is the format field

Response	“ dddd[ dddd]...”
Response
	‘ 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 (‘ dddd’) that will be returned in the requested response. The first datum returned in the response will be for the highest channel number requested. 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	9
			integer
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

Three 3 pressure calibration points will by supplied when we continue this function later see example for ‘01’ sub-command below. A linear 1st order fit will be used to obtain a new set of offset and gain correction coefficients for these four 4 channels. The maximum average sample count 64 is used to collect each calibration data point, so as to minimize any noise in the data samples.
