READ HIGH-PRECISION DATA (Command ‘r’)

Purpose: Returns the most recently acquired engineering-unitpressure data for the specified channels. Each datum returned in the response will be in the specified high- precision data format.

Command “rppppf”

‘r’ is the command letter

‘pppp’ is the position field ‘f’ is the format field

Response “ dddd.. dddd”

‘ dddd’ are datum fields, each with 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 specified. Each (non-binary) datum will be preceded by a space character (except in the case of f= 7). 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: m sb first)		4
8	single binary float	to	single binary float (little endian: lsb first)		4

Unless the EU conversion scalar is altered, the returned data will be in units of psi.
