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

“Vppppf”

‘V’ is the command letter ‘pppp’ is the position field ‘f’ is the format field

Response

Description:

“dddd.. [dddd]”

‘ dddd’ are the data fields, each with a leading space (except f =7 or 8).

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 datum field (‘ dddd’) that will be returned in the requested response. The first datum returned in the response will be for the highest channel number requested, 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
