RPT 301 User Manual 13

3.3General Command Format

The instrument is controlled by a sequence of single letter commands. Some commands require one or more numeric values to follow the letter, the correct number of parameters must be sent with this type of command. All command fields must be separated by a comma. The instrument accepts upper-case or lower-case letters.

Single commands

Single commands should be of the form:

Command, P1, P2, ,Pn<CT>

Where, Command is a single ASCII character, P1 to Pn are numbers in

the form:	(-) mmm.ddd
	or
	(-)m.ddddE(-)xx
	e.g. 123.456 or 1.23456E02
Example:

Single Command

<CT> is the command terminator (CR or CRLF)

A,3<CR> selects auto-send mode with 3 second period

a,3<CRLF> has the same effect

Command Strings

Commands can be strung together with a separating semicolon. The whole command string is only interpreted and actioned when a valid terminator is received.

Example:
