In order to provide security for remote access of the T200, 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 (refer to Section 5.5). 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 T200 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.
