Table 11-11 summarizes the 720i -specific functions
provided by the keyboard interface; most other
alphanumeric and navigational keys provide functions
equivalent to those typical for PC operation. Menu
parameters and serial commands that affect indicator
k e y p a d o p e r a t i o n ( i n c l u d i n g t h e K B D L C K ,
ZERONLY, and KLOCK serial commands) also affect
the remote keyboard.
Note
The keyboard interface is not hot-pluggable.
Disconnect power to the
720i before
connecting the keyboard cable to the Port 1
connector.

11.10 Audit Trail Support
Audit trail support provides tracking information for
configuration and calibration events. To prevent
potential misuse, all configuration and calibration
changes are counted as change events.
Use Revolution III to display audit trail information.
The audit trail display includes the legally relevant
(LR) version number (software version for the code
that provides audit trail information), a calibration
count and, if REGULAT=NTEP, a configuration count.
The exact format of the information shown depends on
the regulatory agency specified for the REGULAT
(FEATURE menu) parameter.
Audit trail information can be printed from Revolution
III or by sending the DUMPAUDIT serial command.
By pressing the MENU key , the Audit Trail menu is
bold. Pressing the Enter key will display the LR
software number and the current audit trail counter.
When done, press
Enter to return to weighing mode.
For NTEP and Measure Canada modes , there are two
numbers displayed; Configs and Calibs. The Configs
n um be r t r a ck s c ha ng es t o the legally relevant
configuration parameter changes. The Calibs number
tracks changes to the scale calibration.
In OIML mode , there is only one number displayed;
Audit Trail. The Audit trail number is incremented for
any legally relevant configuration parameter changes
and all calibration changes. The last date the scale was
calibrated is also displayed.
