READ HIGH-SPEED DATA (Command ‘b’)

Purpose: Returns the most recent scanned/averaged data from all channels of the module as

fast as possible. Data is returned directly in its internal (IEEE single-precision

float) binary form (as per implied format 7). It is used as a faster alternative to

the Read High-Precision Data (‘r’) command, since ‘b’ does not have to parse

the position or format parameters, nor does it have transform or encode the internal

data into any other format when the response is generated.

Command

“b”

‘b’ is the command letter

Response

“aaaabbbbcccc..rrrr”

Each 4-byte datum (e.g, ‘aaaa’) is a non-human readable 32-bit (4-byte)

big-endian value (format 7) representing an IEEE single-precision internal

float value.

Description: Returns data for all of the module’s channels, in order highest channel number to

lowest channel number. Thus for a Model 9016, channel #16 will always be the

first 4-byte (32-bit binary, big-endian, IEEE floating-point) value (‘aaaa’) sent in

the response. For Models 9021 and 9022, channel #12 will be first. It is followed

by similar values for lower numbered channels.

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

Example:

• Send command to a module (via its “socket” connection) to return data as fast

possible:

“b”

Data from the most recent scan of all the module’s channels are returned in pure

binary form, 4-bytes per channel (big endian):

aaaabbbbcccc .. rrrr

Note that this response is not shown within quotes “ ” since it is not a valid ASCII

character string.
