8.4. PASSWORD SECURITY FOR SERIAL REMOTE
COMMUNICATIONS
In order to provide security for remote access of the T300/T300M, a LOGON feature
can be enabled to require a password before the instrument will accept commands. This
is done by turning on the SECURITY MODE (Mode 4, Table 6-1). Once the
SECURITY MODE is
enabled, the following items apply.
A password is required before the port will respond or pass on commands.
If the port is inactive for one hour, it will automatically logoff, which can also be
achieved with the LOGOFF command.
Three unsuccessful attempts to log on with an incorrect password will cause
subsequent logins to be disabled for 1 hour, even if the correct password is used.
If not logged on, the only active command is the '?' request for the help screen.
The following messages will be returned at logon:
LOGON SUCCESSFUL - Correct password given
LOGON FAILED - Password not given or incorrect
LOGOFF SUCCESSFUL - Connection terminated successfully
To log on to the T300/T300M Analyzer with SECURITY MODE feature enabled,
type:
LOGON 940331
940331 is the default password. To change the default password, use the variable RS-
232_PASS issued as follows:
V RS-232_PASS=NNNNNN
Where N is any numeral between 0 and 9.
