In order to provide security for remote access of the M300E/EM, 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, Table 8-1.

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 M300E/EM Analyzer with SECURITY MODE feature enabled, type:
