6.15.2.7. COM Port Password Security
In order to provide security for remote access of the GFC 7000TA, 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, Section 6.11.5). 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 Model GFC 7000TA analyzer with SECURITY MODE feature enabled, type:
LOGON 940331
940331 is the default password. To change the default password, use the variable RS232_PASS issued
as follows:
V RS232_PASS=NNNNNN
