Notations:

<> indicates a single ascii character

[] indicates an ascii string

{} text within the braces describes the response (this is essentially a comment)

“” text within quotes represents a literal ascii text string

Description

<cr>

Carriage Return

ascii Carrage Return. This is a command/response delimiter

<sp>

Space

ascii Space Character

[Accuracy String]

Accuracy String

Part accuracy string. Given in % full scale output.

Example: 0.250%FSO

Notes:

1.) There is a space between the numeric accuracy “0.250”

and units “%FSO.”

2.) FSO stands for Full Scale Output (full scale output is

determined by the Pressure Range String.)

[hhhh]

High Resolution Output

This is a four character ascii string representing a

hexidecimal value.

Example: 3F7C

Represents an output count of 16,252

Note: the output is forced to “8000” upon an error.

except error bit 8, see error bit codes.

[llll]

Low Resolution Output

This is a four character ascii string representing a

hexidecimal value.

Example: 1D58

Represents an output count of 7,512

Note: the output is forced to “8000” upon an error.

except error bit 8, see error bit codes.

[Model String]

Model String

Part Model as given in the data sheet (also order number.)

The general model syntax is

[Full Scale Pressure]<sp>[Pressure Units]-[Pressure Model]-DO

Example: 100PSI-D-DO

Where:

Full Scale Pressure=100

Pressure Units=PSI (inH2O, mbar or mmHg available)

DO represents Digital Output

Notes:

1.) Exception to this syntax is the Barometer.

2.) Custom models may be different.
