Computer Interface, Commands, and Data Collection

Teledyne API Ultrafine Particle Monitor - Model 651

Model 651 in the terminal emulation software. This is because, although the Model 651 and computer are communicating, the command is not understood. You can ignore this error message – it is only used for testing the connectivity. When data is being reported to the screen of the terminal emulation software, you can either, cut and paste the data into a file, or use the software’s data logging capabilities to capture data. Data in the comma-delimited format can be imported into programs such as Microsoft Excel® spreadsheet software for analysis and graphing.

Appendix B, “Firmware Commands” describes the commands that control the operation and data reporting options for the Model 651 instrument.

C o m m a n d s

It is important to note the following information about the commands and responses:

∙Unless specified as binary-encoded, all commands and responses are sent or received as ASCII characters.

∙All messages are terminated with a <CR> (0x0D) character.

∙All linefeed (0x0A) characters are ignored and none are transmitted.

∙Commands are case insensitive. The backspace character (0x08) deletes previous characters in buffer.

∙Values enclosed by “<>” indicate ASCII characters/values sent/received. For example, <,> indicates the comma was sent or received via the communications channel.

The firmware commands are divided into the categories described below.

Commands	Description
READ	Used to read parameters from the instrument (such
	as flow rate, pressure, temperature, etc.). READ
	commands can be identified by a leading "R".
SET	Set an internal parameter to the value(s) supplied
	with the command (supplied parameters are
	always delimited by a comma). SET commands
	can be identified by a leading "S". The instrument
	will reply to all SET commands with the string
	"OK"<CR>.

Note: When the instrument does not understand a command, it replies with the string "ERROR".
