7.4 Diagnostics
The diagnostics mode can be entered from the RS-232 port as well as from the front panel. The
diagnostics commands available are listed on Table 7-6.
Table 7-6: 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.
NOTE
The diagnostics mode may only be entered via the RS-232 port when
the analyzer is in sample mode.
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.
