The “Log” (
LOG
) command allows logging to memory, to be turned on or off. This is used
to test a logger without disturbing the existing logged data. The LED will still flash and the
event will appear on the comms (if EV is on) so the operator can verify the event has been
recognised. When the comms cable is removed (or the sleep timer expires), logging is
automatically turned on !

The “Logger Identification” (
ID
) is a unique number embedded in the MiniLog at the time of
manufacture and can only be read. (The first 2 numbers are the year of manufacture)

The “Site Name” (
SI
) variable is used to either identify a specific logger or the location of the
logger. This is a variable string up to 16 characters long and can be any alphanumeric
character. The user can use this field for whatever they wish.
SI<CR>
Display the present site name.
SI=Sydney<CR>
Set the site name to “Sydney”
The password (
PASSWD
) prevents unauthorised access to altering the parameters or clearing
the historical log record. Password access is cleared when the comms is unplugged and the
MiniLog returns to its sleep mode, or the BYE command is performed.
The password is a 4 character alphanumeric string that is upper / lower case sensitive. New
passwords may be entered by first gaining access by entering the existing password, and then
immediately entering the password command again with a new password.
PASSWD=BOMM<CR>
To attempt access, or change password if access already
accepted.
If the password is set to the special value of ****, then the password function is disabled!
That is, the user does not have to enter the password before they change parameters or clear
memory. For example :
PASSWD=BOMM<CR> Enable
access.
PASSWD=****<CR> Password function disabled.
