In order to provide security for remote access of the T200H/M, 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 (see Section 4.9). 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
o
LOGON FAILED - Password not given or incorrect
o
LOGOFF SUCCESSFUL - Connection terminated successfully
o
To log on to the T200H/M analyzer with SECURITY MODE feature enabled, type:
