Remote Operation

Model GFC7001E Carbon Dioxide Analyzer

8.1.7.5.COMM Port Password Security

In order to provide security for remote access of the GFC 7001E/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 GFC 7001E/EM Analyzer with SECURITY MODE feature enabled, type:

LOGON 940331

NOTE

940331 is the default password.

To change the default password, use the variable RS-232_PASSissued as follows:

V RS-232_PASS=NNNNNN

Where N is any numeral between 0 and 9.
