DIAGNOSTIC COMMANDS

NOTE

THE DIAGNOSTICS MODE MAY ONLY BE

ENTERED VIA THE RS-232 PORT WHEN

THE ANALYZER IS IN SAMPLE MODE.

DIAGNOSTIC COMMANDS

Command		Function
D ENTER SIG		Enter diagnostic Signal I/O mode
D EXIT		Exit diagnostics mode
D LIST		Prints all Signal I/O values. See Table
		5.2 for Signal Definitions
D name[=value]		Examines or sets I/O signal. See
		Table 5.2 for a list of signals. Must
		issue D ENTER SIG before using this
		command.
D RESET		Reset analyzer(same as power on)
D RESET RAM		Resets analyzer and erases RAM.
		Erases all DAS data. Keeps setup
		variables and calibration
D RESET EEPROM		Resets analyzer and erases RAM and
		EEPROM. Erases all DAS data.
		Resets all setup variables to factory
		default. Resets calibration values.
	TABLE 7.5

These commands may be used whether the diagnostics have been entered from the keyboard (SETUP-DIAG) or the RS-232 ("D ENTER <CRLF>"). However, when the diagnostics are entered via the keyboard, no feedback is sent to the RS-232 channel. This prevents the RS-232 output from getting unnecessarily cluttered with diagnostic data.

Whenever the diagnostic mode is entered or exited, a report is issued to the RS-232 output. The table below summarizes the diagnostic reports.

FAQ

What is the purpose of the diagnostic commands?

The diagnostic commands allow the user to enter diagnostic Signal I/O mode, print Signal I/O values, reset the analyzer, and more.

How can I enter the diagnostic mode?

The diagnostic mode may only be entered via the RS-232 port when the analyzer is in sample mode. See the manual for specific instructions.

What feedback is sent to the RS-232 channel when entering the diagnostic mode via the keyboard?

No feedback is sent to the RS-232 channel when entering the diagnostic mode via the keyboard, preventing unnecessary clutter of diagnostic data.
