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
