4.15.2.7. COM Port Password Security
In order to provide security for remote access of the 9110TH/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:
o
LOGON SUCCESSFUL - Correct password given
o
LOGON FAILED - Password not given or incorrect
o
LOGOFF SUCCESSFUL - Connection terminated successfully
