8.4. COM PORT PASSWORD SECURITY
In order to provide security for remote access of the T802, 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, Section 6.2.1).
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 T802 analyzer with SECURITY MODE feature enabled, type:
LOGON 940331
Note 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.
