Some Notes about Programming and Syntax Diagram Conventions

The first colon can be left out for the first command or query in your message. That is, the example given above could also be sent as INP:WAV 1313.

Command and Query Syntax

All characters not between angled brackets must be sent exactly as shown.

The characters between angled brackets (<…>) indicate the kind of data that you send, or that you get in a response. You do not type the angled brackets in the actual message. Descriptions of these items follow the syntax description. The most common of these are:

string	is ascii data. A string is contained between a ' at
	the start and the end, or a ' at the start and the
	end.
value	is numeric data in integer (12), decimal (34.5)
	or exponential format (67.8E-9).
wsp	is a white space.

Other kinds of data are described as required.

The characters between square brackets ([…]) show optional information that you can include with the message.

The bar () shows an either-or choice of data, for example, ab means either a or b, but not both simultaneously.

Extra spaces are ignored; they can be inserted to improve readability.
